What Is Climate Change? How climate change raises the risk of glacier and rock collapse Climate change means abrupt shifts in temperature and weather. Some of these shifts occur naturally, while others result from human activities such as burning fossil fuels like coal, oil and gas. Burning fossil fuels produces greenhouse emissions that act like a blanket wrapped around the Earth, trapping the sun's heat and raising temperatures. The main greenhouse gases, such as carbon dioxide and methane, cause climate change. Clearing land and deforestation can also release CO2. Agriculture, oil and gas are the primary sources of methane emissions. These are a few of the main sources of greenhouse gases. We face a huge challenge, but we have many solutions. Climate change can be reduced by eliminating CO2 from the atmosphere, which requires systemic changes. The United Nations Environment Programme estimates that countries must double their pledges under the Paris Agreement within the next dec...
