I am getting a little tired of reading all the doom-and-gloom AGW stories in the media recently. As the Copenhagen Conference draws nearer, it will only get worse, so I will try to focus on more positive things.
Remember, before I left for Europe, I mentioned that I would be gone during the annual sea-ice minimum in the northern hemisphere. This is something that is closely watched and generally generates a media frenzy when it gets quite low. What happened this year? The sea-ice was the third lowest on record. What is interesting is that the sea-ice has been increasing year over year since 2007. After reading so many reports on how positive feedback cycles were going to accelerate the loss of sea-ice, I find it surprising that we seem to be going in the opposite direction. Perhaps there is a mechanism that is pushing things in the opposite direction. If El Nino sticks around through the winter, I wonder if that will affect the arctic sea-ice. I am not aware of a connection between the two, but the last two years we had La Nina during the winter and the sea-ice increased. Anyway, more sea-ice is good news (as long as it is not part of a new ice age…lol).
For those worried about carbon emissions, there is more good news. New methods for burying carbon underground are in development. This particular approach would pressurize power plant effluent into a liquid stream of CO2 and pump it underground. Some people are worried about pumping CO2 underground, but at least there are options.
How about this? Direct drive could make wind turbines cheaper to maintain. GE is pushing to use direct drive in offshore wind turbines.
Floating manmade islands/piers, in rivers could generate electricity for cities and also serve as new green/park space for residents. When it comes to energy, there are a lot of new ideas.
Data centers (for the internet) are using a growing share of the world’s energy resources, however, a new trend in computing called “cloud computing” – where you store your data in a server instead of in your computer at your house, could lead to much more efficient operation. A new data center constructed by Yahoo in New York will use one quarter of the energy that their older data center’s use.
A little side detour in to space news: It is looking increasingly likely that there is water on the moon. Data from several different spacecraft are building the case for water and this is good news for any future potential moon bases.
And now what I would like to call time wasting links. These are some cool photo galleries for those who are interested in science and nature.
A photo gallery of glaciers as they appear from space.
Crazy pictures of the big Australian dust storm.
Some cool impact craters found around the globe.
New visiualization techniques help scientists understand complex and large data sets.
Have a good Thursday! Meteorologist Justin Loew.
