“The use of stone to make stone that can cut flesh is important,” Richard Leakey said. “We’re not empirical things, we’re thinkers. … What was it that triggered that response?”

From Sendai to Rio: A Call for Action

Japan damage from 2011 tsunami

The people living on the northeast coast of Japan had learned to expect large earthquakes. But despite being one of the best-prepared nations, they were caught off-guard by the force of the March 11, 2011, earthquake and tsunami that devastated their coastline and led to the meltdown of reactors at the Fukushima nuclear power plant.

Can we manage the needs of 9 billion people for water, food and energy without depleting our resources and ruining the environment? “The solutions,” says Tim Fox, “are all within the capability of existing technology.”

The United States and five other countries agreed this week to fund an effort to cut emissions of methane, soot and other pollutants to start to slow the rate of human-induced climate change.

Russian scientists this week finished penetrating more than two miles through the Antarctic ice sheet to Lake Vostok, a huge freshwater lake that has been buried under the ice for millions of years. But they won’t know what they’ve found until next year.

The NYC Department of City Planning has proposed new zoning rules to make it easier to retrofit buildings for energy efficiency – including a provision on rooftop greenhouses.

Fast & Cheap: Shortcuts to Curb Global Warming

by | 1.12.2012 at 3:13pm | 7 Comments
Landfills are rich in methane-producing bacteria that decompose garbage. Typically, excess methane simply leaks into the atmosphere, but a system of pipes can capture the gas underground and divert it to power plants instead. Installing such systems on a broad scale could reduce human-caused methane emissions by 8 percent, according to a new study.

Relatively cheap, simple steps using existing technologies could cut projected global warming by one degree Fahrenheit – a substantial amount — by focusing on sources of methane and soot, concludes a new study by an international team of scientists.

Earth Institute Science in Spotlight

Sediment cores taken from the Dead Sea indicate the area has dried up almost completely, probably in conjunction with the recession of glaciers. In the middle of a relatively dry period, the lake is under additional stress now from human consumption. (Photo: Adi Torfstein)

Research presented by Earth Institute scientists at the 2011 American Geophysical Union fall conference generated a lot of attention from the media. Much of it came from a press conference held to discuss findings by Steve Goldstein from the Lamont-Doherty Earth Observatory and his colleagues on the potential for future drying up of the Dead Sea.

From Distant Past, Lessons on Ocean Acidification

Oceans turned more acidic during a period of great warming some 56 million years ago, causing an extinction of bottom-dwelling marine species known as foraminifera, a scenario that may be happening again now, only much more quickly.
