After a long lull in activity, I decided it's about time I write an update about my thoughts on global warming. Here it is.

I recently stumbled upon one of the most meaningless papers I have ever seen. The paper "proves" that the scientists advocating an anthropogenic greenhouse warming (AGW) are statistically more credible than the "unconvinced". Their main goal is to convince people that they should join the AGW bandwagon simply because it is allegedly more credible.

Last May I had a conference in the island of Vulcano. During the conference I had a half day excursion to the Island of Stromboli, where I climbed the mountain and got to see one of the most impressive geological phenomena one can see... Here are my impressions, photos and even a movie of it.

After being asked once too many about the climategate scandal, I decided it would save me some time if I simply wrote down my opinion about it.

There are 12, but that's not the main point of this blog entry...

A week ago was Earth day, and just like the trend elsewhere, Israel joined with an hour long blackout. In principle, I am very much in favor of environmental awareness, and if it brings some, so be it. But if you ask me, overall, this event is a rather pointless gimmick. Why?

I few months ago, I had a paper accepted in the Journal of Geophysical Research. Since its repercussions are particularly interesting for the general public, I decided to write about it. It's called, using the "Oceans as a Calorimeter to quantify the solar radiative forcing".

I recently returned from Lijiang (in Yunnan, China). One of my legs was a flight from Chengdu to Beijing, and it is certainly a flight I will never forget.

I recently attended the 3rd Space Climate Symposium which took place in Saariselkä, about 250 km north of the arctic circle in Finnish Lapland. Because of the prolonged solar minimum, my hopes were for a high auroral activity, but my expectations were not. Luckily, it was my hopes which were fulfilled!

Here is a summary of the northern lights I have seen.

If you check the dates, you'll notice that I am utterly delinquent with respect to posting at this site. Unfortunately, it is because I have an administrative post - I am chairman of the faculty union at the Hebrew University. And it really takes up precious time, which otherwise, would have allowed me to write.

Just recently, Sloan and Wolfendale published a paper in Environmental Research Letters, called "Testing the proposed causal link between cosmic rays and cloud cover". In the Institute of Physics Press Release, it said, "New research has deal a blow to the skeptics who argue that climate change is all due to cosmic rays rather than man made greenhouse gases". Did it really?

Realclimate.org continues with its same line of attack. Wishfulclimate.org writers try again and again to concoct what appears to be deep critiques against skeptic arguments, but end up doing a very shallow job. All in the name of saving the world. How gallant of them. This time it is an ill-founded attack by Jahnke and Benestad.

Jerusalem was under siege, again. Last time it was Bush. This time, it was snow because of which we had two snow days. So, I didn't have to teach and instead could build a snowman with my kids. I could also look at the rain radar, which appeared to exhibit a few interesting phenomena.

One of the phenomena appears to be that of open-cell convection, i.e., air rising (and precipitating) on the cell boundaries.

A few words about the longest strike ever in the Israeli Universities, a strike which ended last week. No science in this post. Sorry.

On my personal views of President Bush's visit to my humble town of Jerusalem. A few thoughts about quantum mechanics and the speed of sound.
