Lakes also feel global warming

As we all now, global warming has been affecting our planet for several decades, now. The temperature has been increasing everywhere on Earth. Some scientists have decided to measure yet another effect of global warming, and that is the heating up of the lakes around the globe.
Between the years of 1985 and 2009, scientists conducted an experiment, where special kinds of satellites measured the temperature of the surface of 167 lakes. Scientists discovered a schocking result. The lakes got warmer at the rate of 0.045 degrees Celsius per year. In some lakes, the hating up rate was as high as 0.10 degrees Celsius a year. Even though this might not seem like a very big number, it can be, because it can cause the algae in the lakes to start reproducing rapidly. A lot of algae can make the lake poisounous for the fish. Another fact that was discovered is that lakes get warmer faster in the northeren parts of the Northern Hemisphere. However, it was also found out that in the United States, the lakes in the south-western part, warmed more quickly, then the big lakes in the north. This is quite interesting, and also quite stressing, because you can't come up to a conclusion to where the lakes are warming faster.
Scientists also found out that in some regions, the lakes are getting warmere then the air around them. And, even though it is schocking, this can help scientists. How? Well, the scientists constantly take the air, and then measure it's temperature, to see how the global warming works, and to get a better idea of how the Earth is warming up. Now, that the scientists can also measure the temperature of the surfaces of lakes, that will help them get a clearer image of what we are doing to our planet. However, there are still people who are willing to help our planet, and that is why the United Nations Framework on climate Change, will be held this year from November 29 until December 10, in Cancun, Mexico. Representatices from different countries will come and discuss how the Kyoto Protocol has been doing. The Kyoto Protocol is a plan to help the Earth by making all the big polluters reduce the greenhouse effect, and the emmisions of CO2.
I think that it is good that they are having a conference about global warming, but that won't change anything. They need to go out there, and speak to people about it, and inform them on what they could do, to make even a slight difference. This is a problem on a planetary scale, and I find it really shocking that now, our lakes are getting affected, as well.
