The IPCC summary for policy makers is out, and as I started writing these lines so was the last draft of the main report. Of course, it will take a while to digest the 2200 pages of the full report (it has a lot of starch!). Until I do, here are my first impressions from having read the summary and having skimmed the full scientific report.

Spring weather here in Israel was rather strange. Although winter with most of its precipitation should have been over, we had a few very rainy days. We're now in the midst of a heat wave with temperatures as much as 20°C higher than just a week before. In between there was a nice gravity wave appear over the Arava Valley, the first one I have ever seen in a rain radar!

A very interesting paper recently appeared in nature. It describes the detection of a precursor eruption of a supernova progenitor more than a month before the supernova explosion itself. It is particularly interesting because this detection was not serendipitous—it was based on my prediction.

Last month I participated in EIKE's (Europäisches Institut für Klima und Energie) conference on Climate Change. They video record the lectures, which means that mine is now online. I thought I'd share it with you. Have fun.

My wife and I had our kitchen renovated. Since this involved breaking a few walls (and cutting out a new window), we knew it would raise a lot of dust. Mind you, here in the middle east houses are built from concrete and concrete blocks, not wood. To minimize the dust annoyance (and damage), we decided to quarter off the living room from the kitchen by using large nylon sheets hung from the ceiling to the floor. 

After the dust settled down (literally…), we found something quite bizarre. The nylon walls developed very beautiful dust dendrites, akin to the more familiar frost dendrites (like these frost dendrites I have seen while living in Toronto). 

I was asked by quite a few people about my opinion on the BEST analysis of Richard Muller and his group in Berkeley. Since I didn’t want to keep my friends without an answer, I took a more careful look into the analysis. Here is what I think of it.

There are two parts to the analysis. The first part is a reconstruction of the temperature over the 20th century. The second part includes analyzing this reconstruction and drawing various conclusions out of it.

After being busy with the submission of two research proposal and trying to stay afloat with the pretty heavy teaching load I have this semester, I decided I should take a short break and post something on my blog. I actually have quite a few things I have been wanting to write about, but it seems that the most relevant thing is the the mini-war which is raging not to far from here. So, I thought I'd stray from my usual and write about the middle east.
