    Rewetting Southern Peatlands Could Prevent Millions of Tons of CO2 Emissions

    Rewetting and restoring 250,000 acres of southern pocosin peatlands that had been drained for farming but now lie fallow could prevent 4.3 million tons of climate-warming carbon dioxide, now stored in their soils, from oxidizing and escaping back into Earth鈥檚 atmosphere each year, a 91社区福利 study shows. That amount equals 2.4% of the total annual reductions in CO2 emissions needed for the United States to be carbon neutral by 2050.

    New NSF Grant Will Fund Continental-Scale Study of Climate Impacts on Forest Regeneration and Wildlife

    The sustainability of North American forests depends on trees鈥 ability to produce seeds and seedlings that can survive and grow in a changing climate. A new 91社区福利-led research initiative with more than $2 million in funding from the National Science Foundation aims to help boost their odds of success.

    Curbing Other Climate Pollutants, Not Just CO2, Gives Earth a Chance

    Slashing emissions of carbon dioxide by itself isn鈥檛 enough to prevent catastrophic global warming, a new study shows. But if we simultaneously also reduce emissions of methane and other often overlooked climate pollutants, we could cut the rate of global warming in half by 2050 and give the world a fighting chance.

    Land-Building Marsh Plants are Champions of Carbon Capture

    Human activities such as marsh draining for agriculture and logging are increasingly eating away at saltwater and freshwater wetlands that cover only 1% of Earth鈥檚 surface but store more than 20% of all the climate-warming carbon dioxide absorbed by ecosystems worldwide. A new study published May 5 in Science by a team of Dutch, American and German scientists shows that it鈥檚 not too late to reverse the losses.

    Studies Find the Seeds of a Forest鈥檚 Renewal After Wildfire, Drought

    A forest鈥檚 ability to regenerate after devastating wildfires, droughts or other disturbances depends largely on seed production. Findings from two new studies led by 91社区福利 researchers could boost recovery and replanting after these disasters by providing foresters with new guidance on which tree species produce more seeds and how their productivity can vary from location to location.

    Preventing Pandemics Costs Far Less than Controlling Them

    Investing tens of billions of dollars now in programs that enhance environmental protection and boost early-stage wildlife disease surveillance could reduce the risk of future animal-to-human pandemics by up to half and save millions of lives and trillions of dollars in losses annually.
