And this (dated two years ago, but based on an eight year project in Antarctica) explains what Global Warming is, as well as what it does. It seems that the polar ice caps are melting, and the permanent ice is shrinking at the rate of 9% per decade, at which rate they will have disappeared by the end of this century. Some of that ice is 890,000 years old! Check out the graphics on the Arctic ice, and the likely impact on Bangladesh. There are two projections on global average temperatures for the rest ovf this century, from the UN environment programme(UNep) and the Intergovernmental Panel on Climate Change (IPCC).
Sceptics, and those with vested interests in industries which produce high fuel emissions, may continue to scoff, but if English farmers are now able to grow almonds, apricots, olives and kiwi fruit in the open, (See 'Almonds are the new English roses), you have to wonder!
Where have I found all this? See the infrequent farmer, who has decided to work with climate change. He's in my sidebar, and well worth reading.
