Climate change and the problems that cause global warming. The combustion of fossil fuels is the largest contributor to the increasing concentration of greenhouse gases (GHG) in the atmosphere. Scientists have gathered conclusive evidence temperatures :1.5°C and 5.5°C above current temperatures by 2100. CO2 emissions and the top 10 emitting countries account for about two-thirds of the world CO2 emissions. Both the extent and thickness of Arctic sea ice has declined rapidly over the last several decades. . The U.S. Climate Change Science Program issued a report predicting an increase in extreme weather in North America, including both floods and droughts, as a result of global warming. There is strong evidence that that heavy downpours will become more common and more severe along with the rise in global temperature. Some scientists have hypothesized that warmer ocean surface temperatures will lead to an increase in hurricanes and tropical storms.Consequences of global warming and rising sea. A global solution: renewable energy in generating electricity. Will create a federal Renewable Portfolio Standard (RPS) that will require 25 percent of American electricity be derived from renewable sources by 2025, which has the potential to create hundreds of thousands of new jobs on its own. In his annual State of the Union address, President Obama called for legislation that would require the generation of 80% of US energy from "clean" sources by 2035.
