In ocean carbon recycling, size matters

The journal Nature Geoscience published a study today from UCI Earth system scientists on the size-reactivity continuum in the ocean carbon cycle. Detrital (not living) organic matter is a very large reservoir of carbon stored in the world’s oceans; it’s roughly equal in size to the amount of carbon dioxide in Earth’s atmosphere. Marine organic matter spans […]

Tree species influence boreal forest fire behavior and subsequent effects on climate

Irvine, Calif., Feb. 2, 2015 – For a better understanding of how forest fires behave and interact with climate, scientists are turning to the trees. A new study out of UC Irvine shows that differences in individual tree species between Eurasia and North America alter the continental patterns of fire – and that blazes burning […]

Satellites reveal possible catastrophic flooding months in advance, UCI finds

Data from NASA satellites can greatly improve predictions of how likely a river basin is to overflow months before it does, according to new findings by UC Irvine. The use of such data, which capture a much fuller picture of how water is accumulating, could result in earlier flood warnings, potentially saving lives and property.

Ocean plankton sponge up nearly twice the carbon currently assumed

Irvine, Calif. – Models of carbon dioxide in the world’s oceans need to be revised, according to new work by UC Irvine and other scientists published online Sunday in Nature Geoscience. Trillions of plankton near the surface of warm waters are far more carbon-rich than has long been thought, they found. Global marine temperature fluctuations […]

Soil microbes produce less atmospheric CO2 than expected with climate warming

As global temperatures increase, microbes in soil become less efficient over time at converting carbon in soil into carbon dioxide, a key contributor to climate warming.

Glacier in West Greenland

Warmer ocean speeding Greenland glacier melt

Glaciers in West Greenland are melting 100 times more rapidly at their end points beneath the ocean than they are at their surfaces, according to a UC Irvine/NASA study.

Antarctic ice loss speeds up, nearly matches Greenland loss

Ice loss in Antarctica increased by 75 percent in the last 10 years due to a speed-up in the flow…
