Over at Wattsupwiththat.com I read that the Swiss mountain glaciers were melting at a faster rate in the 1940s than they are today.
"The most recent studies by researchers at ETH Zurich show that in the 1940s Swiss glaciers were melting at an even-faster pace than at present. This is despite the fact that the temperatures in the 20th century were lower than in this century. Researchers see the main reason for this as the lower level of aerosol pollution in the atmosphere."
By aerosol pollution they mean soot and other small particles in the atmosphere. These can be caused by volcanic eruptions among other things. They're not all down to man made global warming.
The earth's climate may be changing. The glaciers may indeed be melting. But it's just wrong to put it all down to man made global warming. We need honest study; study where the results are not controlled by a cheque book or vested interests. I have no axe to grind other than a genuine desire for the truth.
We have more to fear from the cold than from the warmth. It's possible that we could still be in the grip of the Little Ice Age, when the Thames would freeze over and fairs be held on the ice, were it not for the effects of the Industrial Revolution, where the atmosphere was heated by countless factory chimney stacks. But that could also have been a coincidence.
Apparently they can grow potatoes in some parts of Greenland again. But remember, when the Vikings discovered it over a thousand years ago, they named it because it was green with vegetation. That was during the Medieval Warm Period.
The climate changes. It always has. It's not all down to man. Perhaps the sun has something to do with it?
