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...
Funding Environmental Issues: Past, Present and Future Environmental issues are changes to nature that are bad and mostly caused by human activity. These problems affect air, water, soil, plants, animals and human health. They are connected to each other, so solving one often helps solve others. The History of Environmental Problems Coal consumption increased during the Industrial Revolution and as cities became more smoke-filled, the serious environmental damage increased. In the 1800s and early 1900s, scientists began to understand how carbon dioxide traps heat in the atmosphere. The 1970s saw the advent of global activism. The United Nations Environment Program (UNEP) was founded at th...
