A scientist the Bush administration tried to gag is writing about recent climate discoveries.
A satellite study of the Greenland ice cap shows that it is melting far faster than scientists had feared - twice as much ice is going into the sea as it was five years ago. The implications for rising sea levels - and climate change - could be dramatic.

Yet, a few weeks ago, when I - a Nasa climate scientist - tried to talk to the media about these issues following a lecture I had given calling for prompt reductions in the emission of greenhouse gases, the Nasa public affairs team - staffed by political appointees from the Bush administration - tried to stop me doing so. I was not happy with that, and I ignored the restrictions. The first line of Nasa's mission is to understand and protect the planet.

This new satellite data is a remarkable advance. We are seeing for the first time the detailed behaviour of the ice streams that are draining the Greenland ice sheet. They show that Greenland seems to be losing at least 200 cubic kilometres of ice a year. It is different from even two years ago, when people still said the ice sheet was in balance.
Sounds like Greenland is soon going to be a nice place to buy real estate. I'm more worried about the beachfront properties in the rest of the world.

Greenland had much less snow cover a thousand years ago than now. The Vikings were able to live there and raise cattle etc. Then it gradually got colder and snow-covered year round and they had to leave their colony there. The greenhouse effect can't happen unless something stops convection or air circulation. The runaway greenhouse theory comes from the idea that Venus is now so hot because it's atmosphere is mostly CO2. But that's not why it's hot. Venus is rapidly cooling, not heating up. It's hot because it's a young planet. Planets form by fissioning off of larger planets or stars. Lots of theories in astronomy are wrong, because they don't take electrical forces into account. Over 99% of the universe is plasma, which is ionized matter, which is electrically charged. So electrical forces need to be considered. A good site on this is www.thunderbolts.info. Aloha.

The study about climate has been advanced a lot from the traditional ways. Today, we have satellites that provide us necessary information about these facts.

Thanks for sharing.Is as a peacemaker. I find debating painful. I am not good at it. plain and simple. I admire those who can do it well.
