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.

Over the past two weeks, perhaps a dozen people asked me about the recently published paper of Shakun et al. in Nature. It allegedly demonstrates that the global temperature followed CO₂ around the warming associated with the last interglacial warming, between 20 to 10 thousand years ago. One even sent the story as a news item on NPR. So, having no other choice, I decided to actually read the paper and find what is it all about. Should I abandon all that I advocated over the past decade?

Dear Rep. Adam Schiff (representing California's 29th district).

Although I presently live outside the US, I am a registered voter in the 29th district which you represent. I kindly ask that you will drop your support of SOPA.

Out of curiosity, I opened a few weeks ago a poll asking the visitors of this site, what do they think is the primary cause of global warming. 429 people answered the poll (thanks to all of you!).

The results can be summarized as follows.

First, the visitors of this site have the following background:

Background	Fraction (Votes)
Layman	54.9% (232)
General Scientist	41.1% (174)
Climate Scientist	4.0% (17)

A few days ago I had a very pleasant meeting with Andrew Bolt. He was visiting Israel and we met for an hour in my office. During the discussion, I mentioned that the writers of the recent IPCC reports are not very scientific in their conduct and realized that I should write about it here.

A few weeks ago, the hacker/whistleblower has done it again. A new release of a large amount of e-mails from the same source (University of East Anglia) has surfaced in Russia. It is most likely from the same original batch because the last of the new e-mails is from 2009. Here is my perspective of things. Here are my thoughts about it.

Any repeating visitor will notice that I have changed the site. In fact, besides changing the appearance, the backbone engine running the site was upgraded from drupal 5 to drupal 7. Here is a very short summary how the site was upgraded.

Three weeks ago I visited the underground laboratory of Gran Sasso near l'Aquila. Little did I know that it would make headline news so soon, for "discovering" particles moving faster than the speed of light. Since a few people asked me what did I think of it, I decided to write something about it here.

The CLOUD collaboration from CERN finally had their results published in nature, showing that ionization increases the nucleation rate of condensation nuclei. The results are very beautiful and they demonstrate, yet again, how cosmic rays (which govern the amount of atmospheric ionization) can in principle have an affect on climate.

Masada, the Dead Sea, the Messinian Salinity Crisis and Augustus Ceasar, all in one post.

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...
