This generally involves reductions in human emissions of greenhouse gases (GHGs).. Fossil fuels account for about 70% of GHG emissions. Though global warming used to be the more popular expression among environmental scientists, climate change is now preferred because it encompasses effects beyond the rising temperatures around the globe. Heating of the oceans accounts for over nine-tenths of the trapped energy. These gases trap heat in the atmosphere and change weather patterns, warming many areas of the globe and causing, and continuing today, the burning of fossil fuels (oil, natural gas, and coal) increased at a very high rate.

Climate change refers to significant changes in global temperature, precipitation, wind patterns and other measures of climate that occur over several decades or longer. The main challenge is to eliminate the use of coal, oil and gas and substitute these fossil fuels with clean energy sources. In particular, the uses of vehicles like cars and planes have caused carbon emissions to skyrocket. Burning these materials releases what are called greenhouse gases into Earth’s atmosphere. Reducing carbon emissions is no longer enough to halt the impacts of climate change. Climate change mitigation consists of actions to limit the magnitude or rate of global warming and its related effects. This can all be contributed to climate change. The American pika, for example, is a small mammal that lives in cool mountainous areas in western North America—in fact, it can die when exposed to temperatures warmer than 78˚F.So as the mountain climate heats up, the pika climbs the slopes in search of cooler habitat.
