Ancient plankton help researchers predict near-future climate

Temperature data inferred from plankton fossils from the Pliocene, an era with CO2 levels similar to today’s, allowed a research team to rectify discrepancies between climate models and other proxy temperature measurements.

New Studies Increase Confidence in NASA’s Measure of Earth’s Temperature

A new assessment of NASA’s record of global temperatures revealed that the agency’s estimate of Earth’s long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing evidence that past and future research is correctly capturing rising surface temperatures.

Leafcutter ant colonies may be an overlooked source of carbon dioxide emissions, new study finds

Factories mass produce goods for society and many emit greenhouse gases in the process, but not all are run by humans. Some factories lie underground and are operated around the clock by tireless six-legged workers. A new study in the Journal of Geophysical Research: Biogeosciences, a journal of the American Geophysical Union, shows leafcutter ant nests can emit carbon dioxide at a rate thousands of times higher than regular soil.

Diving robots find Antarctic winter seas exhale surprising amounts of carbon dioxide

More than 100 oceanic floats are now diving and drifting in the Southern Ocean around Antarctica during the peak of winter. These instruments are gathering data from a place and season that remains very poorly studied, despite its important role in regulating the global climate.

Researchers find mushrooms may hold clues to effect of carbon dioxide on lawns

Researchers at the University of New Hampshire set out to determine how rising carbon dioxide concentrations and different climates may alter vegetation like forests, croplands, and 40 million acres of American lawns. They found that the clues may lie in an unexpected source, mushrooms.
