A New 66 Million-Year History of Carbon Dioxide Offers Little Comfort for Today
Scientists have produced a new curve of how atmospheric carbon dioxide affects climate. It makes clear that its effects can be long lasting.

Climate Change May Have Huge Impacts on Staple Crops Within 10 Years, Says NASA
The study projects that wheat will do better in temperate regions, but corn production could plummet in warmer ones. Some crops may decline in nutritional value.

Taro Takahashi, Who Uncovered Key Links Between Oceans and Climate
Taro Takahashi, a seagoing scientist who made key discoveries about carbon dioxide and the earth’s climate, has died. In a career spanning more than 60 years, he and his colleagues documented how the oceans both absorb and give off huge amounts of carbon dioxide, exchanging it with the atmosphere.

Where Is All That Carbon Dioxide Going?
Concurrent with the announcement that human carbon emissions reached a new peak this year, Galen McKinley, a researcher at Columbia University’s Lamont-Doherty Earth Observatory, discusses the difficulties of tracking the sources and destinations of carbon dioxide.

Why are Past Surface Temperatures and CO2 Concentrations Important?
Kelsey Dyez, a geochemist at the Lamont-Doherty Earth Observatory, describes how the carbon dioxide content of the atmosphere influences climate.

What Geology Has to Say About Global Warming
The most important lessons drawn from geology are that the earth’s climate can change radically, and rapidly. We can’t say precisely at what CO2 level we’re in danger of melting Antarctica, but that threshold could be reached in 150-300 years, if CO2 levels keep rising at the current rate.
