What is climate change?

Fossil fuels contain carbon which has been buried in the ground for millions of years. When burnt, the carbon is released into the atmosphere in the form of carbon dioxide , a colourless odourless gas. Carbon dioxide is one of the gasses known as greenhouse gasses , so-called because they trap the sun’s heat within the atmosphere in much the same way as the glass in a greenhouse traps the heat. As the concentration of greenhouse gasses in the atmosphere increases, the global temperature rises. The effects of this are wide ranging, and include: Melting of polar ice caps and glaciers in mountainous regions Desertification Rising sea levels due to melted ice Reduced albedo of the planet due to melted ice Flooding due to melting of glaciers Flooding due to increased sea levels More extreme weather, like Hurricane Katrina Collectively, these effects are known as climate change. Our planet exists in[…]
