A Conversation With Whales

In the article referenced below, the New York Times writer investigates one of the animals on the endangered species list according to NOAA fisheries: the sperm whale. The population of the sperm whale has declined 70 percent in the last 150 years. Although the article’s intention is not to highlight this fact, I think it is worth noting due to our recent time spent studying the red list and other life forms that are in peril because of depopulation. In this case with the sperm whales, the cause is due to the amount that have been killed by humans for food and oil. In this article, however, the objective is to investigate the intellect and social capabilities of sperm whales. The process that is under investigation by the free diving scientists is the practice of coda clicks by which the whales communicate. Objectively, at first exposure, the sounds seem primitive and unintelligent in nature, but upon further investigation by the team, there have been much more intricate and elaborate parts found within each basic sounding click. The interesting part of each click is found “when the clicks are viewed on a spectrogram, a visual representation of an audio signal, each reveals a remarkably complex pattern. Inside these clicks are a series of shorter clicks, each lasting a few thousandths of a second”. The most fascinating part, in my opinion, is the potential that these clicks have in terms of communication. While socializing, the sperm whales very possibly could be communicating in a much more complex and intellectual way that previously thought. Even more interesting is the possibility that arises if we are able to decode these clicks and use them to converse with the whales.

New Zealand Penguin Population

One of the most rare and endangered species is the yellow-eyed penguin that resides in New Zealand. This species of penguin is very shy to humans and is hard to be spotted because they are always hiding under thick shrubbery when humans approach. This penguin is the most rare and just 10 years ago the population was around 6,000; and today the population is around 2,000. One of the leading factors for this penguin to be endangered is that only 18% of the babies survive their first year of life. As we learned in Module 11 of class, the main reason for the continued trouble for the bird is caused by humans. The largest human impact is farmers are bulldozing their habitats to create areas to raise cattle and sheep. The farmers didn’t realize the damage they were doing to the penguin’s habitat. Another factor causing deaths of these penguins is cats and dogs are preying on the animals and taking out young penguins before they have a chance to grow up and reproduce. The leading cause of death for baby penguins is heat stress, which is becoming worse and worse with increasing temperatures from the global climate change.

The increasing climate change and human impacts will continue to cause problems for the yellow-eyed penguin and other animals around the world. It will be interesting to see how animals and humans adapt to the increasing concerns of endangered species.

Climate Change Hits Hard in Zambia

As reported by the New York Times in the article “Climate Change Hits Hard in Zambia, an African Success Story”, the country has been affected by climate change due to droughts but environmentalists report that the Kariba Dam remains steady. The dam is known to be of the world’s largest hydroelectric dams that provide the country with electricity.

The Kariba Dam has contributed to the country’s economy and political stability becoming as they continue to be one of the fastest growing economies in the continent. Unfortunately, due to droughts, the water levels have hit record lows. In the past, the Kariba even provided electricity to neighbor countries but the reserves are not enough for Zambia. This has affected the stability of the country and they are now struggling to pay their civil servants.

Due to power cuts, companies such as Good Time Steel, the biggest steel maker in the country, lost a third of its production capacity. Jacky Huang, a manager at the company, explains that the company has recently abandoned new projects due to the conditions of the country.

Zambia is only of the many countries in Africa whose economic stability is being affected by climate change. Many say the continent is not ready for the climate changes and Africa is expected to warm up faster than the rest of the world. Zambia is starting to see the economic damage as small and large business are being affected due to the Kariba Dam shortages.

 

Module 11 lab

Why is much of the tropics considered as a biodiversity hotspot?

Well the term hotspot is any place with at least 1500 types of vascular plants that are uniquely occurring in that area. https://www.learner.org/courses/envsci/unit/text.php?unit=9&secNum=4 Tropical plants can’t thrive in places that aren’t tropical. Palm trees can’t grow in Detroit. Tropical rain forests have the distinction of having thousands of different plants and tens of thousands of different animals that don’t occur in other parts of the world. That and the diversity in plant life would satisfy the definition of a biodiversity hotspot. http://www.eoearth.org/view/article/150650/ All the animals in the tropics have adapted to live in the tropics, they can’t transplant to Fargo, North Dakota and survive there. Many of them, such as the poison dart frog need to keep their skin moist through the humidity of the rain forest and will die without it. Evolution has permanently affixed these animals and plants to living in this one biosphere.

Acreage for Genetically Modified Crops Declined in 2015

The world’s farmers have increased their use of genetically modified crops steadily and sharply since the technology became broadly commercialized in 1996; however, this will not be the case anymore.  The article states that 2015 was the first time the acreage used for the crops declined.  According to a nonprofit that tracks, the plantings of biotech seeds.  The organization said the main cause for the decline, which measured 1 percent from 2014 levels, was low commodity prices, which led farmers to plant less corn, soybeans and canola of all types, both genetically engineered and non-engineered.  Only three countries account for more than three-quarters of the total global acreage. And only four crops account for the majority of biotechnology use in agriculture.  In many cases, more than 90 percent of those four crops grown in those three countries, and in other large growers like Canada, India and China, is already genetically modified, leaving little room for expansion.

There have been efforts to expand use of biotechnology to other crops and to other countries. These have created difficulties due to opposition from consumer and environmental groups, regulatory hurdles and in some cases scientific obstacles.  The International Service for the Acquisition of Agri-Biotech Application’s plan is to help small farmers in developing countries take advantage in biotechnology.  This in turn can increase farmer income and reduce use of chemical pesticides.  It receives financial support from various foundations, companies, trade groups and governments, including Monsanto and the United States government.  The overall acreage planted with biotech seeds in 2015 fell 1 percent globally to 444.0 million acres, from 448.5 million acres in 2014.  The crops were grown in 28 countries and used by up to 18 million farmers, most of them small ones in developing countries, the report said.  I guess we will just have to wait and see how this all plays out.  Allow more time to collect data and move from there.

Exxon

Recently papers have been released by The Center for International Environmental Law.  The papers show that Humble Energy has know about rising CO2 levels since 1957 which is nearly 60 years.   The data also demonstrated that rising CO2 levels would cause warming earth temperatures.  Humble Energy now belongs to Exxon a major energy company. The papers also reveal that Exxon used the information to plan against regulation.  This is because oil would be less profitable with more regulations to prevent CO2 from rising.  Investigations by four attorneys in the US Virgin Islands are underway.  Exxon does not have an ties to the Virgin Islands meaning their courts hold little influence.  However Exxon has already challenged the investigation in Texas.

Although Exxon denies any involvement of hiding or abusing climate science, the papers seem to be evidence of the contrary.  The company once again acknowledged that climate change may be a threat.  Showing the issue is whether Exxon withheld valuable information when they first discovered the problem in 1957.

Honey Bees: ASU Researcher’s Study May Help Improve Lifespan

According to the Module for this week annual losses of colonies averaged about 33% each year and 1/3 of this percentage is from colony collapse disorder (CCD). In an article published in Arizona news, a study on honey bee larvae performed by Arizona State University’s School of Life Sciences was explained. The cause of decline, explains researcher is caused by a combination of stressors such as parasites, pathogens, pesticides, environmental changes and malnutrition. The objective of the study was to better understand the resilience of the bee colonies that survive through tough living conditions. Researchers found that when bees are challenged nutritionally by being denied food, it changes the fundamental physiology that affects them when they are adults. They also found that by starving bees during their development, they become more resistant to tough living conditions and CCD. The more starved these bees are, the more susceptible to disease they are. The study urges beekeepers to keep bees as close to their natural state as possible meaning no pesticides or antibiotics. Also to stay away from agricultural and urban practices. Researcher from this study concludes by adding, “the effort of the scientists and beekeepers to understand bees and save bees have resulted in significant enhancement of honey bee health by improving bee management practices.” This might be true but colonies are still collapsing and honey bees are still on the decline. There is always more to do.

Continued scrutiny of Exxon for climate change knowledge

Documents from Exxon regarding its knowledge of the causes and effects of climate change, and the company’s role in the former, continue to surface. Sure, the idea that Exxon lied to the public about climate change might damage its PR, but to what end? Information, like that released a few days ago (1), further solidify the argument that Exxon had a moral obligation to change its behavior based on its knowledge of climate change, but morals did not keep Exxon from lying about the negative impact that burning fossil fuels has on climate. So what about legal obligations? Will any executives receive criminal charges for deceiving the public? Unlikely, based on lack of precedent. Then what civil charges can be brought against Exxon that will incentivize it to change behavior?That’s what the focus of news about Exxon should be on. I think that consumers are unlikely to stop buying Exxon gas based on their perception of the company (but I want the news to inform me about this, too!), and even if they want to, they’re unlikely to know if Exxon has had a part in extracting or refining their purchased gas. For example, Sheetz gas is probably a mix of Exxon and other sources, but you can’t know for sure, because Sheetz doesn’t know for sure (2).

We know companies do things to things to protect themselves. That usually ends up sucking for public health, but it’s not news. The things I want to know are: will citizens complain to their representatives if they know that Exxon is scummy? How likely are representatives respond in such a way that damages Exxon’s profits? How likely is success of litigation against Exxon for lying to investors about climate change, and so the value of the company, and what effect would success have?

Sierra Nevada Snowpack and Its Effects

Throughout this course, the class has been analyzing climate change and its effect on the different places around the world.  In the article I have chosen to blog about this week, titled “Sierra Nevada Snow Won’t End California’s Thirst” the New York Times discusses how the snowpack in Sierra Nevada was greater this year than it has been in years.  The cause of the snowpack is stated as primarily El Nino and definitely the result of changing climate systems.  This snowpack serves as an important factor as it supplies water for the surrounding regions, especially California.  The article states that the Sierra snowpack supplies California with nearly 30 percent of their water as the snow melts and flows into rivers and reservoirs.  Also, the snowpack is even more valuable than just rain because the accumulation of snow serves as a reservoir that gradually melts, supplying the needs of industries, people, agriculture, and forests.  It is interesting to keep finding out new ways that climate change is effecting the places we live in.  I found this article specifically interesting because I was unaware of how detrimental the snow influences the populations around them.  California continues to live with water restrictions and it is crazy to think that as global warming continues and gradually increases the situation may only get worse.

NASA is Facing a Climate Change Countdown

NASA’s two largest launch pads are located a quarter of a mile away from the encroaching ocean. These launch pads sit atop of two 50 foot artificial hills. Most of the Florida Space Coast is in threatening danger due to climate change. Researchers have proposed that the sea levels could rise five to six feet by the end of the century due to the warming of the Antarctic ice sheet. An astronaut, named Scott Kelly, just recently returned from a year long trip in space and spoke of differences in the earth that he had observed from his prior trip from 2010. He stated, “It seems to me there is more pollution in India and China than what I saw last time. Definitely noticed the fires this summer in the USA; sometimes, could see the smoke all the way to Chicago.”

Much of the land that is owned and operated by NASA is “within 16 feet of mean sea level”. This means that the sites owned by NASA will be under severe threat from climate change although, retreating the facilities inland is not an option. The most inexpensive way to deal with climate change would to be upgrading the facilities to prepare for the changing climate. The reason these billion dollar facilities are located on the coast is due to the fact that it is much safer to launch rockets over water than over land and human civilization. The article finishes with a very sound statement, “Water, once the solution to many of the space agency’s problems, is becoming its biggest threat.”

Blog 11 – Climate change is polar bears’ biggest threat

Polar bears, which depend on seasonal sea ice which they use as a platform to hunt mammals after their summer fast, are declining in number really fast. There are less than 25,000 polar bears left and its population will decline by 30% by 2050 due to the loss of their habitat. The amount of sea ice at its lowest point each year has shrunk at a rate of 14% per decade.  Thus, annual ice-free periods of five months will spread hunger among polar

The ice is freezing later in the fall, but its is the earlier spring ice melt that is especially difficult for the bears since they have a narrower timeframe in which to hunt during the critical season when the seal pups are born. That has direct impact on the average bears weight, which has dropped 15% causing reproduction rates to decline. Also, remaining ice is farther from shore making it less accessible. These larger gaps of open water make the bears’ swim more hazardous

The shrinking polar ice cap will also cause a decline of seals. Thus, polar bears are started to display cannibalistic behavior due to longer periods of hunger, instead of killing others for dominance or so they can breed with the female.

However, warming temperatures are not the only threat polar bears face; human invasion, pollution and resource exploitation add to this negative spiral.We should start taking action before it is too late to help prevent potentially catastrophic consequences.

I personally think that should be a responsibility for ALL countries because such a large epidemic like that could begin to effect other surrounding countries if we do not step in and help stop the problem in one place. If other countries just sit back and watch sea level rise and destroy a country it will only get worse for those other countries because as other places are destroyed, they sit back and do nothing about it and contribute to the problem, making it worse for everyone all over the world and causing these problems to occur faster.

 

In the article Drowning History: Sea Level Rise Threatens US Historic Sites” it talks about many different historic sites across America that are low-laying by the water, as well as speaking about historic sites all over the country. The article tells you about how all of these historic sites can be ruined or even completely submerged because of sea level rise, if sea level rises only 3 feet it can cause 1.5 billion dollars’ worth of damage to the Statue of Liberty. In Boston the annual amount of floods in the 1070s was only two, in between 2009 and 2013 the amount rose to 11 and could rise to 72 floods a year if sea level would rise to 11 inches. The article also speaks about Newport, Annapolis, and Jamestown, Hawaii, and sites in other countries like South Africa on Robben Island where Nelson Mandela was imprisoned for 27 years.

So when sea level rise affects one place or one country it is really effecting all of us, and what really we need to do is rise about these levels and help each other.

Climate Change a Massive Threat to Food Security and Agriculture

The article “Climate Change is a Massive Threat to Food Security and Agriculture” talks about the impact of climate change in Australia for the future. It starts by alerting the Australian people that they can expect climate change to make food scarcer as well as expensive in the near future. The fact that the earth is getting warmer and warmer every day is having a significant impact on crop yields in southern Australia. Another fact that is also contributing to this impact is the low rainfall that Australia is suffering lately due to climate change.

The bad news is that these negative factors will only become bigger in the future and therefore crop yields will continue to be affected and in a larger scale. It is important to note that some extreme weather events such as droughts, cyclones, and bushfires will end up leading to a significant decrease in productivity regarding the agricultural sector in Australia. This is a really big issue in the country since agriculture is responsible for $50 billion of the country’s GDP, which represents about 2.4%. Besides that, Australia exports a big number of agricultural products, and suffering from the decrease in production will lead to less money coming into the country. These factors discussed previously will also cause Australia’s strong food security characteristic to become less strong.

Some farmers have started to change their way of production in order to try to escape from this severe issue. They count on the young generation of farmers that seems to be more knowledgeable regarding this topic. Australia definitely needs to make changes in its agricultural culture in order to be able to adapt to climate change, otherwise the country will suffer severely from food security as well as in economic power.

Antarctic Ice May Melt Faster Than Expected

Scientists are predicting that Antarctica’s western ice sheet may be actually melting faster than previously expected. Scientists have developed physics-based simulations that can forecast melting of ice in different areas. The focus of the simulations in the article were targeting the area of Western Antarctica. The simulation states that in the worst scenario possible, the sea level in that area could raise 18-34 inches by 2100. This amount is higher than predicted a few years ago. The article states that if the world is able to control greenhouse gas emissions to levels they pledged in the past, then the sea level rise will still be 3-12 inches higher than previously predicted. These predictions bring a new alarming fact that needs more and more attention to control the future sea levels. The simulations are also predicted by the year 2500, the sea level could be a total of 42 feet higher. This is a huge problem because that big of a sea level rise will likely flood the entire world. Antarctica is a rather difficult area for scientists to predict because the ice is a lot thicker and melts at a slower rates than other ice areas. It will be interesting to see what the future holds with ice melting and the way it affects sea level rises.

Alarming Climate-Related Death of Coral Around World

As explain in the New York Article, “Climate-Related Death of Coral Around World Alarms Scientists”, researchers have found devastation in coral around the world, specifically in the Kiritimati Island. As Kim Cobb, a marine scientists, reports there is substantial devastation even 30 feet underwater with “red-brown fuzz” covering the entire reef.

Scientists believe that the heat stress created by weather events have affected the coral reefs. While some may not know the importance of the reefs, coral provide food and shelter to many marine species. Consequently, this affects the human population as many marine species feed over a billion people. Also, millions of people depend on fishing as their main income around the world; In the Philippines alone, more than a million people are in the fishing industry.

Bleaching is a consequence of high heat and bright sunshine which recently has been out of control. Bleaching refers to the acceleration of the algae metabolism which can create toxins. Scientists explain that even if temperatures to drop and the corals recover, many will remain vulnerable to disease and if the temperatures continue to rise, the corals will starve to death.

Scientists recently found the largest bleaching at the Australia’s Great Barrier Reef with only four sectiong of of 520 individual reefs with no signs of bleaching. Australia is not the only region affected, other dying reefs include Réunion, East Flores, Guam, and many more. As temperatures continue to increase, Kobb worries about the future of corals. Most recently, water temperatures were reported to be 10 degrees warmer than average which does not allow coral to recover.

Rising Sea Level and Its Effects

In module 10, the class discussed how rising sea levels are becoming a more prominent issue and how they effect a vast amount of things within our environment.  In the article I have chosen to blog about this week “NASA Is Facing A Climate Change Countdown” the New York Times writes that NASA is facing some serious problems due to the rising sea level and other issues involved with climate change.  In the article, one of the leading scientists for NASA explains that beaches surrounding the facility used to be nearly 50 yards out, however, in recent days are barely 10.  The sand of the facility beaches is being swept away by coastal erosion and storms.  The problem becomes even more severe when looking at where a few of the larger launchpads are located, and how they may be underwater in future years.  While NASA is already seeing issues among there vast amount of facilities across the nation from climate change, it is noted that these changes will only become more severe as warming increases, sea levels rise, and storms become stronger.  I found it really interesting to read how government facilities such as NASA are being affected just as much as the general public and how the effects of global warming are already being noticed.  The pictures within the article showed the severe changes and I am curious to see how NASA will deal with this issue moving forward.

Schwartz, John. “NASA Is Facing a Climate Change Countdown.” The New York Times. The New York Times, 04 Apr. 2016. Web. 10 Apr. 2016. <http://www.nytimes.com/2016/04/05/science/nasa-is-facing-a-climate-change-countdown.html?rref=collection%2Fsectioncollection%2Fearth&action=click&contentCollection=earth®ion=rank&module=package&version=highlights&contentPlacement=1&pgtype=sectionfront&_r=0>.

Rising Sea Levels Could Cost NASA Billions

In a 2014 report, researchers for NASA concluded that sea levels could rise as much as two feet by 2050, and more recently a study concluded that sea levels could rise as much as six feet by the end of the century. Seeing as two thirds of NASA’s $32 billion worth of structures are within sixteen feet of mean sea level and much of it coastal, this will have huge impacts for the leader in space exploration. NASA reports that coastal flooding at Johnson Space Center in Texas could double in frequency, flooding at Kennedy Space Center in Florida could as much as triple in frequency and flooding at Ames Research Center in San Francisco could increase as much as ten-fold. NASA uses their status as the leader in space exploration to spread information and raise awareness about global warming and change and how it impacts the rise of sea levels and other aspects of our planet. Astronaut Scott Kelly, while aboard the ISS for a year, took numerous photographs of the planet. These photographs show increases in pollution in Asia and India. The smoke from the California wildfires is visible all the way to Chicago. Smog above Mexico City can be seen clearly. Storm systems are occurring in unexpected places. NASA and their astronauts attribute these storm systems to the increased pollution and the fragile atmosphere. Satellite pictures taken by U.S. and international satellites show a clear rise in sea level that NASA believes is linked to the melting of the polar caps from this increased pollution and global warming.

 

Unless global warming is addressed in a serious manner, this could end up costing NASA billions of dollars in repair, moving and environmental rebuilding.

Rising Sea Level Threatens NASA Facilities

Sea level rise is a prolific topic in climate change that I have written about a few times this semester. This week brings a new victim to be threatened by the rising tides: the National Aeronautics and Space Administration. Besides leading the world in space exploration, NASA also contributes a great deal of research on climate change and its impacts, making it ironic that they should be among those expected to be most immediately effected. Furthermore, I would have expected NASA to be among the most prepared groups, as they work on some of the nation’s most sophisticated technology. However, about two thirds of NASA’s facilities lie within 16 feet of sea level and along coastlines [1], making them exceptionally vulnerable to storm surges coupled with rising sea level. Couple the billions of dollars of investment and low elevation with an expected increase in the magnitude of hurricanes going forward, and you have a recipe for disaster. The Kennedy Space Center in Florida will likely be the first to experience these effects, as their beaches are already showing signs of major erosion, but the centers in Houston and San Francisco will likely also begin to see these changes by the end of the century. While retreat from the shorelines may be a slow, expensive, and difficult process, it will likely become necessary in the future. For this reason, and as with all issues related to climate change, it is best to begin investing in that solution now before the problem becomes too large and exceeds our ability to cope.

  1. http://www.nytimes.com/2016/04/05/science/nasa-is-facing-a-climate-change-countdown.html?rref=collection%2Fsectioncollection%2Fearth&action=click&contentCollection=earth&region=rank&module=package&version=highlights&contentPlacement=1&pgtype=sectionfront&_r=0

The main purpose of this article was to show how climate change has been killing coral which is leading to negative effects in the water ecosystems. Kim Cobb, a researcher from the Georgia Institute of Technology was sampling coral in in the Kiritimati Islands when she was something strange. She saw that an entire coral was covered with “red brown fuzz”.  The “red brown fuzz” was algae that grew on top of dead coral. All this coral is dying due to the mass bleaching that is occurring around the world. Some scientist believe that severe heat stresses that came from multiple weather events such as the pass El Nino is causing this problem. According to data that was college by the same scientist, this passed El Nino has threatened more than a third of the Earth’s coral reefs and many may not recover.
This is a big problem because coral reefs are an essential part of the ocean’s ecosystems. They provide food and shelter for a quarter of all marine species. In addition, people that feed off these ecosystems will also be effected because the fish they hunt will disappear which mean that will have to find a new food source. Since the bleaching is still occurring and will not be over for the several months, scientists don’t know how this will exactly affect the ocean’s ecosystem. All they know is that this will have a negative effect on the oceans and this bleaching needs to be closely observed.

 

Glacial Lake Missoula

There is plenty of evidence that the sea flooded the interior of continents in Earth history. About 12,000 years ago, the valleys of Western Montana lay underneath a lake nearly 2,000 feet deep. It was then when the failure occurred. The water pressure caused the glacier to become resilient and the water began to escape under the ice dam. Water reached a maximum height at an elevation of 4,200 feet that debilitated the glacial block until water burst through in a devastating flood that raced across Idaho, Oregon and Washington. Huge waves and pieces of ice ripped away soils and mountainsides, deposited massive ripple marks and carved the Columbia River Gorge. At that point, Glacial Lake Missoula was as big as Lakes Erie and Ontario combined and the flood waters ran with the force equal to sixty Amazon Rivers.

Harlen Bretz and Joseph T. Pardee were the two geologists that studied this event to find the causes of the features in eastern Washington. They realized that these features must have been formed by enormous scale flooding of devastating proportion. It took several years for the geologic community to accept their interpretation but thanks to the clues to the puzzle provided by these two geologists we have been able to discover one of the most unbelievable events in history.

Module 10

Sea level rise will obviously have a direct impact on certain coastal areas.  Do you think that the burdens of dealing with this problem should be the responsibility of all countries, or just the countries with the impacted coastal areas?

Examined from a practical standpoint do I think the world is going to aid every nation where a coast line will be affected by sea level rise? Is Saudi Arabia going to aid Israel if massive flooding happens there? Probably not in this particular universe. Is the U.N. going to show up and help in Bangladesh if they get flooded out? That’s sort of what they exist to do.

In our collective unconcious we can only really see past our massive differences through the empathy of tragedy. https://en.wikipedia.org/wiki/Collective_unconscious Flooding is easy to relate to for most countries because most of them have rivers that flood.  It’s why the movie “Independence Day” has one of the best speeches in any movie ever about the fourth of July no longer being an american holiday, because we can all empathize with fighting aliens, even though we’ve never actually done that. https://www.youtube.com/watch?v=9t1IK_9apWs

But if the question is will any country put the well being of people they’ve never met before over the needs of their people, even if they really don’t want to meet those same needs. You ever met a politician who ran on a platform of, “Let’s help those people over there with that thing”? I didn’t think so. This is probably gonna be a country by country solution.

Methane, and decoupling of emissions and growth

The International Energy Agency released preliminary data from 2015 regarding countries’ respective GDP and CO2 emissions, noting that even in China and the US, GDP has increased as reported CO2 emissions have decreased (1). Although, the IEA must rely on voluntary emissions reporting, and many Chinese firms have allegedly intentionally understated their CO2 emissions, so that the data may not be entirely accurate (2). Likewise, the IEA’s report solely measures CO2 emissions, but methane accounts for about a quarter of current global warming. As countries continue to replace coal with natural gas, methane emissions are projected to increase even as CO2 emissions decrease (3). Politically, the IEA’s report is great news, since the seemingly unfounded fear among many politicians is that the economy must suffer in order to regulate GHG emissions, but I wish the IEA’s report measured CO2 equivalent instead of just CO2.

The Loss of Treasured Places

Sea level rise will of course change the appearance of landscapes that have been known and treasured by many, but the effects of sea level rise far surpass the nostalgic emotions of a changing place.  I took this opportunity to do some research into a place that I have loved since I was a child, and a landscape that I treasure.  Cape Cod, in Massachusetts, has been the inspiration of novelists and poets, including Mary Oliver.  It is home to a national park: the Cape Cod National Seashore, which was set aside by President Kennedy as a place that he also treasured.  Like many places, it is drastically changing.

A report by the U.S. Geological Survey warns that sea level will rise about 8 inches.  I have watched the water wash away the land and convert grassland to marshland.  Alongside this rise in sea level comes a correspondingly larger rise in storm surges and the potential for flooding.  If water were to rise 10 feet above its normal levels during a storm, it would cover route 6 and cut off Provincetown from the rest of the Cape.  If a 4 foot rise occurs as the result of a storm, nearly 5,000 homes would be destroyed.

A digital tool, created by the Cape Cod Commission, further shows the effects of hurricanes on the coast of Cape Cod.  A category 4 Hurricane would eliminate much of Wellfleet Harbor (where my house is) and would flood the town of Provincetown on the tip of the cape. The inner cape would also be affected by hurricanes and large storms, as flooding would reach the towns of Dennis and Harwichport.

As I stated, however, it is not just the change in landscape and flooding of homes and businesses that are at risk with a rising ocean.  Cape Cod home prices are being affected by climate change and rising ocean levels now.

The Boston Globe reported on housing prices in Truro, the town between Wellfleet and Provincetown on the outer edges of the Cape.  Sotheby’s International Realty, one of the largest realtor’s on the cape, employs an individual to produce SLOSH flood maps for clients and educate them on the quickly eroding sand on the ocean side of the Cape.  Houses have to routinely be moved further from the shore – a fascinating process of lifting a structure and moving it 10 feet backward that I have observed countless times.

Ultimately, rising oceans will change landscapes all over the world, but looking at each of these places as unique and special may help to convey the gravity of the situation to individuals who do not see it.

Illuminating the Effects of Light Pollution

In class we have discussed many different effects and cycles of pollution of the world and atmosphere by gases such as carbon dioxide. The atmosphere is the initial receiver, but it passes the negative effects onto the life forms of earths surface and waters. Similarly, light pollution has recently changed the way things work dramatically in the ecosystem. Like CO2, it is only very recent in the relative history of the earth that humans have been producing artificial light and the production was increased exponentially, in the same way that CO2 byproducts were and still are. The effects of light pollution are certainly less extreme, but they do disrupt the natural cycle of life in many respects. The article mentions the timing of coral spawning in the The Great Barrier Reef being out of sync since the process is dependent on the full moon. Artificial light in some places is easily confused with that of the moon, and therefore the spawning is mistimed and less effective. With reproduction on the decline, the coral that contributes so much to the life of the ecosystem could dramatically affect every other life form above it in the food chain. Another major effect of light pollution is found in the diminishing population of sea turtles. When sea turtles hatch on land, they know to travel to the farthest glow on the horizon (i.e. the moon), but again, the confusion with a nearby developed area in addition to the added light for predators to see by, results in many more baby sea turtles are not making it to the safety of the ocean. There are multiple other consequences of light pollution in our ecosystem including that which affects humans’ circadian rhythm by decreasing the production of melatonin.  Although these side effects are not as impending as those from CO2 pollution, they should receive attention especially since they are already affecting humans directly.

Clouds Cooling Power

Clouds are made up of water and ice. The more water in the cloud influences the amount of solar radiation reflected into the atmosphere.  As the earth warms the ratio of ice to water increases in favor of water.  Since there is more water this should result in more reflection and hence cooling.  However with less ice there is less capacity for water to replace ice, causing more warming.  This means that warming could occur faster than previously predicted by scientists.  A recent study has suggested this could be the difference of 1.3 degrees C.

This would render the goals set by the Paris climate almost useless as their goal was to stop warming above 1.5 degree C.  At the same time the 1.3 degree C rise is only one study so it the actual value is still unknown it could be more or less.  Overall the trend shows warming caused by unpredicted water in clouds ratio. Scientist at Yale who preformed the study stressed that study needs to trigger action not despair or a feeling of hopelessness in combating climate change.

I think that following this discovery makes sticking to the Paris conference even more important.  It also highlights the need for even more action to counter climate change.
