Global Warning! The Earth is heating up and most scientists believe that it's all our fault. When we burn fossil fuels, greenhouse gases such as carbon dioxide increase and surround the earth like a thick blanket. This traps heat and temperatures rise. Scientists say that in the next 100 years, average temperatures will rise by about 3°C. This doesn't sound like a lot, but it means BIG trouble! Ice is already melting, sea levels are rising and the climate is changing. How exactly is all this changing our world, and what will happen if we don't act in time? Cities under the sea According to recent climate reports, melting ice from the polar ice caps and mountain glaciers could cause sea levels to rise by about 1 metre by 2100. If this happens, whole countries such as the Maldives will vanish and millions in low- lying areas like parts of Bangladesh will lose their homes. Already, two small Pacific islands have disappeared under the waves. Coastal cities including Shanghai, Bangkok, New York and London will also be under threat. In Greenland, ice is melting three times faster than just a few years ago. If the ice sheets of Greenland and Antarctica ever melt completely, sea levels will rise about 60 m. That's enough to cover almost every major city on Earth!
