Sunlight has more powerful influence on ocean circulation and climate than North American ice sheets

Sunlight has more powerful influence on ocean circulation and climate than North American ice sheets

(Santa Barbara, Calif.) –– A study reported in today's issue of Nature disputes a longstanding picture of how ice sheets influence ocean circulation during glacial periods.

Rocks could be harnessed to sponge vast amounts of CO2 from air, says study

Rocks could be harnessed to sponge vast amounts of CO2 from air, says study

Scientists say that a type of rock found at or near the surface in the Mideast nation of Oman and other areas around the world could be harnessed to soak up huge quantities of globe-warming carbon dioxide. Their studies show that the rock, known as peridotite, reacts naturally at surprisingly high rates with CO2 to form solid minerals—and that the process could be speeded a million times or more with simple drilling and injection methods. The study appears in this week's early edition of the Proceedings of the National Academy of Sciences.

Zoologists: Sea snakes seek out freshwater to slake thirst

GAINESVILLE, Fla. — Sea snakes may slither in saltwater, but they sip the sweet stuff.

So concludes a University of Florida zoologist in a paper appearing this month in the online edition of the November/December issue of the journal Physiological and Biochemical Zoology.

Ecologists use oceanographic data to predict future climate change

Earth scientists are attempting to predict the future impacts of climate change by reconstructing the past behavior of Arctic climate and ocean circulation. In a November special issue of the journal Ecology, a group of scientists report that if current patterns of change in the Arctic and North Atlantic Oceans continue, alterations of ocean circulation could occur on a global scale, with potentially dramatic implications for the world's climate and biosphere.

Evidence found for climate-driven ecological shifts in North Atlantic, says Cornell study

ITHACA, N.Y. – While Earth has experienced numerous changes in climate over the past 65 million years, recent decades have experienced the most significant climate change since the beginning of human civilized societies about 5,000 years ago, says a new Cornell University study.

When it comes to sea level changing glaciers, new NASA technique measures up

A NASA-led research team has used satellite data to make the most precise measurements to date of changes in the mass of mountain glaciers in the Gulf of Alaska, a region expected to be a significant contributor to global sea level rise over the next 50-100 years.

Global warming predicted to hasten carbon release from peat bogs

CAMBRIDGE, Mass., Nov. 6, 2008 -- Billions of tons of carbon sequestered in the world's peat bogs could be released into the atmosphere in the coming decades as a result of global warming, according to a new analysis of the interplay between peat bogs, water tables, and climate change.
