Recently I read an article in Nature that highlighted major issues with the IPCC report. This article is titled Dangerous Assumptions and written by Roger Pielke, Tom Wigley, and Christopher Green. The main argument put forward by the authors is that the Intergovernmental Panel on Climate Change (IPCC) assumes a large amount of spontaneous technological advancement which is unrealistic and dangerous. For example, 2/3 of the improvements required to stabilize the atmosphere is already built into the IPCC AR4 (4th Assessment) report, their most recent report. The authors argue that the IPCC estimates are optimistic at best and unachievable at worst.

As many of you have noticed, I have not posted to this blog in quite some time. I´ve been preoccupied with travelling in South America for the past 3 months, and have not made the time to post to this blog. For those who are interested in my personal travels, you can check out my other blog here. I have seen some
Hopefully when I return I will get things moving with this blog, but for now it is on a bit of a hiatus. When I get back I´ll try to post some information on some of the climatically interesting things I´ve observed while travelling (e.g., melting tropical glaciers, the driest desert in the world, etc…).

I didn’t expect to see stories in the news on the Arctic Sea Ice extent this early in the season, since the minimum sea ice extent does not occur until around September. But as of now, it looks as though the melt is tracking last years record loss.
This will be interesting to monitor… For those who are interested, the progress of the sea ice can be monitored here from a webpage set up by the National Snow and Ice Data Center here in Boulder.

Recently I ran into an interesting website, www.eoearth.org. On this website there is various information and one page in particular talked about Climate Change (collection). While reading this webpage I ran into another link for a timeline. Well I do love my history so I clicked on it, it actually is quite informative and shows how long climate research has really been going on. Take a look!

Have you ever wondered how much other planets in our solar system are like Earth? Venus is especially much like Earth because they have similar characteristics such as chemical make-up, mass, distance from the sun, and size. Many Scientists have theorized that Venus and Earth started out the same and over time, have changed into the state they are in now. European Scientist have more evidence to prove that theory with the recent mission to Venus. Evidence of even more similar characteristics such as strong atmospheric winds, lightning storms, and cloud vortexes over it’s polar regions according to the article “Venus Craft Reveals Lightning, Supports Watery Past” by James Owen from the National Geographic (November 2007).
