Hazardous Living: Climategate climatologists cleared of wrongdoing

Last November, a thousand private e-mails between prominent climatologists were hacked, resulting in a brouhaha that threatened to discredit the work presented in the Nobel Prize-winning Intergovernmental Panel on Climate Change’s Fourth Assessment Report.

A Martian icecap, now in 3-D

Move over, James Cameron. Researchers have created the first 3-D subsurface pictures of Mars’ northern icecap — and they’re using these images to solve a 40-year-old Martian puzzle.

The puzzle centered around Chasma Boreale, an ice canyon in the northern icecap that is comparable in size to the Grand Canyon, and the spiral troughs that extend in a pinwheel-fashion from the icecap’s center. How each of these features formed has long mystified researchers.

Blogging on EARTH: "Climategate" scientist tells his side

SAN FRANCISCO: In November, hackers broke into the e-mail server of the University of East Anglia’s Climate Research Unit and stole thousands of e-mails dating back to 1996 written by and to climate scientists. The e-mails, which were then leaked to the public, contained the typical stuff of science (and of e-mails, for that matter): amid discussions of data and theory, there was debate, confusion, flippancy, dark humor and questioning.

Crystal Ball EARTH: Policy: A tale of two years

In U.S. policy, the past year was dominated by discussions of energy and climate change issues, at least in the earth sciences realm. In the first year of his administration, President Barack Obama focused on his top campaign priorities — but between discussions of healthcare reform, trying to rejuvenate the economy and setting up his cabinet, he still found time to discuss the sciences.

Why red leaves remain elusive in Europe

As leaves change color every fall, the North American landscape transforms from a rolling verdure to a collage of vibrant yellows, oranges and reds. The autumn foliage in Europe, however, is rather bland, composed of mostly yellow leaves with red-leafed trees few and far between. Why this is the case has remained a mystery for years. But discovering why Europe’s leaves don’t turn red is only half of the battle; determining why the trees’ leaves turn yellow in the first place is the other.

Raindrop study splashes old assumptions

Predicting the weather has been central to human civilization since the Babylonians started studying cloud patterns in 650 B.C. The key to weather predictions is making correct assumptions. Today, instruments like Doppler radar that measure rainfall work under the assumption that raindrops fall at their terminal velocity. A new study, however, shows that some raindrops fall faster than they should, indicating rainfall instruments — and by extension, weather forecasts — may need some tweaking.

Earth: The movie (not the magazine)

Blogging on EARTH (the magazine)

Earth Day is over. But you don’t have to wait until next year to celebrate the planet. Disney’s new movie “Earth,” which opened Apr. 22, offers some spectacular views of the planet and its inhabitants.

Capturing carbon from coal plants: Is it feasible?

On a remote patch of rolling plain in western North Dakota lies a massive labyrinth of buildings, tanks, towers, pipes and conveyors. This industrial behemoth — the Great Plains Synfuels Plant — is designed to turn the vast deposits of lignite coal that lie in the ground into substitute natural gas.

Iron fertilization foiled by "shrimp"

The argument over whether ocean iron fertilization is a good way to sequester carbon dioxide may be coming to an end. Last month, a group of researchers seeded 300 square kilometers of the southwestern Atlantic Ocean with six metric tons of dissolved iron. Just as researchers hoped, algae bloomed, doubling in biomass within the first two weeks of the fertilization. But then, an unexpected guest showed up: tiny shrimp-like crustaceans that dined on the algae.
