The liberal use of water for irrigation by farmers cultivating rice is contributing to a rapid drop in groundwater levels In the northern Indian state of Haryana.

Convincing farmers that it’s worth it to reduce their water consumption will rest on our ability to help develop local groups to manage aquifers at the community-level.

In a Melting Iceland, Drilling Deep to Stem Climate Change

Underground, carbon dioxide disperses through volcanic basalt, and solidifies into a substance similar to limestone. A geologist shows off a core taken from the injection zone.

Iceland is pioneering a new technology to deal with climate change. Its Hellisheidi geothermal power plant, the world’s largest, hosts arguably the world’s most advanced program to capture and lock away globe-warming carbon dioxide.

Iceland has a complicated relationship with climate change. As in much of the far north, global warming is already exerting many effects here–arguably both good and bad. Yet the country contributes relatively little to the warming, since most of its energy comes from geothermal and hydro plants, which produce little carbon dioxide. Now, it is on the scientific cutting edge of the issue.

I hear that the Archean Earth
Spewed lava and was hot,
(While much later, “Snowball Earth,”
Apparently was not),
Some have said that life sprung out of
Spreading-ridge-type stew,
Photosynthesis seems likely
Based on carbon records, too.

In the Ice

Some examples of the sea ice that we have encountered so far. Top left: bands of grease ice, Top right: small pancake ice merged together; bottom left: larger pancake ice; bottom right: The Nathaniel B. Palmer steaming through dense sea ice cover.

Several days ago we reached our main work areas along the margin of East Antarctica. Our expedition is relatively late in the season and the seas around Antarctica are starting to freeze.
