There is some more good news on the global warming front. Al Gore and Canadian environmentalist Sheila Watt-Cloutier have been joinly nominated for the Nobel Peace Prize.

Climate change is also a threat to global welfare. One hundred million climate refugees, major changes in potable water supply and a reduction in biological diversity that will first and foremost hit the poor who live in and depend upon nature – these things will quickly become a major security threat.

It is nice to see people taking notice and taking action. It gives me hope.
