"Extreme Ice" on PBS' NOVA series

Want some real evidence of Climate Change? If you missed the PBS program "Extreme Ice" you missed a lot. The program, a collaboration between PBS (Public Broadcasting) and National Geographic, highlights the rapid decline of glaciers around the planet. And even more worrisome, the unexpected changes in the Greenland and Antarctic ice caps. While losing the mountain glaciers will only bring sea level increases of one to three feet by the end of this century the loss of the major ice caps would cause changes in the hundreds of feet! This would be very bad news for any major coastal cities.

Still think Climate Change is BS? Time to wake up.

• Don't forget! Earth Hour 2009 tonight at 8:30pm local time. Lights out for a hour to make your statement. #


• #earthhour good participation in Auburn. Probably around 30 to 40%. Someone got the memo! #

Nature Conservancy's State of the Birds report

I don't know about you, but one change I've seen in my environment is a reduction in birds in my backyard. Whether it's domestic cats (hopefully not, I have two!), habitat destruction, or climate change something is causing a steep decline in our avian friends. There is good news and bad news in the report. Download (4mb PDF) the report and read it for yourself.

ESA's Earth Explorer Satellite Program

ESA (European Space Agency) will be launching a series of satellites named Earth Explorers. Each of these satellites will examine our planet with a different set of instruments. Our planet is changing in many ways and these robotic explorers will help us understand how and why.

The first mission, Gravity field and steady-state Ocean Circulation Explorer (GOCE), just launched from Russia and will map the Earth's gravitational field in detail. An unique mission, the GOCE satellite flies at the edge of the Earth's atmosphere with constant orbital corrections provided by an ion engine. The next missions are listed below from ESA's web site:

ADM-Aeolus
The prime aim of the Atmospheric Dynamics Mission is to demonstrate measurements of vertical wind profiles from space, using a high performance Doppler Wind Lidar based on direct-detection interferometric techniques. ADM-Aeolus is due for launch in 2011.

EarthCARE
Earth Clouds Aerosols and Radiation Explorer (EarthCARE) will improve the representation and understanding of the Earth's radiative balance in climate and numerical forecast models. EarthCARE is due for launch in 2013.


Opportunity missions:

SMOS
The Soil Moisture and Ocean Salinity (SMOS) mission, scheduled for launch in 2009, will exploit an innovative instrument designed as a two-dimensional interferometer for acquiring brightness temperature observations at L-band (1.4 GHz) for the estimation of soil moisture and ocean salinity to further our understanding of the Earth's water cycle.

CryoSat-2
The CryoSat-2 satellite replaces CryoSat, which was lost as a result of launch failure in October 2005. Scheduled for launch towards the end of 2009, CryoSat-2 will measure fluctuations in the thickness of ice on both land and sea to provide conclusive evidence as to whether there is indeed a trend towards diminishing ice cover, furthering our understanding of the relationship between ice and global climate. CryoSat-2 will carry an innovative SAR/Interferometric Radar Altimeter (SIRAL).

Swarm
The objective of this mission is to provide the best-ever survey of the geomagnetic field and its temporal evolution in order to gain new insights into the Earth system by improving our understanding of the Earth's interior and climate. Swarm is due for launch in 2010.

North pole expedition looking for signs of climate change

A British team is on the arctic ice this Spring looking for signs of climate change. The Catlin Arctic Survey will be trying to determine if the Arctic ice cap is breaking up and if it is, put a solid time frame on the break up. To this end, the three team members, Pen Hadow, Ann Daniels, and Martin Hartley will be out on the ice from February to about May. They will be carrying a ground-penetrating radar that allows the expedition to measure ice thickness and composition.

You can follow the survey at the Catlin Artic Survey's website.
