As you may have seen, it rained quite a lot the first day we were at ALV. I realized that I am not only short on goodlooking clothes, but also on real raincoats. The one I had functioned the other way around. It was like bees to honey. But I am sure you agree with me that it´s just because of the “unexpected” or “special happening” that you remember it better. A time worth remember. It´s like 70 hours in a car, singing “100 bottles of…” or discuss important issues with close friends. Do I recommend you to visit this place? Yes!

Tomorrow I will tell you two things I experienced that could have ended in catastrophy.
Speaking of climateexchange; Here are some quotes and links that give light to the global warming and how close to disaster we actually are:
"According to Dr. James Hansen, a top climate scientist at NASA, it´s much more important to hurry than we thought. “-If we wait ten more years this way, we will pass the point where it´s impossible to make everything right again. It would be as warm as it was thousands of years ago…” …”if we shall have any chance to change anything it must happen whithin one, two or three years.”

The top climate scientist at NASA says the Bush administration has tried to stop him from speaking out since he gave a lecture last month calling for prompt reductions in emissions of greenhouse gases linked to global warming.

The scientist, James E. Hansen, longtime director of the agency's Goddard Institute for Space Studies, said in an interview that officials at NASA headquarters had ordered the public affairs staff to review his coming lectures, papers, postings on the Goddard Web site and requests for interviews from journalists.

The authors use the model for climate simulations of the 21st century using both "business-as-usual" growth of greenhouse gas emissions and an "alternative scenario" in which emissions decrease slowly in the next few decades and then rapidly to achieve stabilization of atmospheric CO2 amount by the end of the century. Climate changes are so large with "business-as-usual", with additional global warming of 2-3°C (3.6-5.4°F) that Hansen concludes "'business-as-usual' would be a guarantee of global and regional disasters."
"Climate effects may still be substantial in the 'alternative scenario', but there is a better chance to adapt to the changes and find other ways to further reduce the climate change," said Sato.
While the researchers say it is still possible to achieve the "alternative scenario", they note that significant actions will be required to do so. Emissions must begin to slow soon. "With another decade of 'business-as-usual' it becomes impractical to achieve the 'alternative scenario' because of the energy infrastructure that would be in place," says Hansen.

"Civilization developed, and constructed extensive infrastructure, during a period of unusual climate stability, the Holocene, now almost 12,000 years in duration. That period is about to end".
Dr. Hansen has been saying for three years that we have, at best, ten years to stop the rise in CO2 emissions and start their decline, or the earth will become 'a different planet' than what we have taken for granted for thousands of years. But we have seen very little changed in government policy and it appears that Dr. Hansen feels it is necessary to take it up a notch.

Twentieth century sea level trends, however, are substantially higher that those of the last few thousand years.
Since 1993, an even higher sea level trend of about 2.8 mm/yr has been measured from the TOPEX/POSEIDON satellite altimeter.
Recent observations of Greenland and the West Antarctic Ice Sheet raise concerns for the future. Satellites detect a thinning of parts of the Greenland Ice Sheet at lower elevations, and glaciers are disgorging ice into the ocean more rapidly, adding 0.23 to 0.57 mm/yr to the sea within the last decade.
A global temperature rise of 2-5°C might destabilize Greenland irreversibly.

ALV looks a lot of fun. Berit has turned into a giant since I saw her last!
About the climate change articles: very interesting. "I don't think it's real." That's what a student of mine said in class. She even argued that glaciers were growing in certain parts of the world, so we have nothing to worry about. But, as a teacher in speech class, I have to allow for students to express freely and without restrictions (sometimes, unfortunately)! I can only direct and give them info to credible sources. Very frustrating, especially when it comes to very polarizing issues. "An Inconvenient Truth" is a pretty eye-opening documentary.

An Inconvenient Truth is a Great documentary! Pretty frustrating when people deny the scientific community and listen to nutjobs like Rush Limbaugh instead...but I was encouraged driving through Oklahoma and Texas last week. We saw lots of wind generators in the fields. Yesterday when we flew over Holland we noticed them sitting on platforms in the ocean. It feels good that we have at least began the process to find alternative and clean energy.
