In the article, the phenomenon of climate change was discussed with a focus on the rising temperatures of lakes around the world. This is an important issue that needs to be analyzed because as the temperatures increase, there is major risk in effecting fresh water supplies and various ecosystems around the world. Also, fresh water is used for manufacturing, energy production and irrigation to crops, so if the temperatures continue to rise, there will be an effect on certain properties within different ecosystems and that can hurt humans and animals of all kinds.

To analyze these trends, scientist collected twenty five year of satellite temperature and ground measurement data from 235 lakes around the world. What they found was that the lakes of the world have a rising temperature of 0.61 degrees every decade and that is significantly higher than the rising temperatures of the oceans and the atmosphere. In addition, the rising temperatures of the lakes also will increase algal blooms. This is an issue because algal blooms can rob the water of oxygen and can be toxic to the fish and animals that use those certain lake. The rising temperatures also effect emissions of methane and greenhouses gases. They are predicted to go up by 4% by the end of the decade.  

From the analysis of the lakes, it has become clear to scientist that these changes that they observe are unavoidable and already taking place. Scientist have to come up with ways to help ecosystems adapt to these changes because it is impossible to reverse the changes. This problem is something that needs more attention or else many communities and ecosystems will be negatively affected over the next few decades.
