Chemist Peter Psarras has good reason to call himself a musical rock star—after all, he plays bass and keyboard semi-professionally—but he’s more likely to claim “rock” stardom of the geological bent....
The U.N.’s Intergovernmental Panel on Climate Change suggested in a recent report that with every degree of warming, global agricultural production will be reduced by 10 to 25 percent, threatening the...

Unexpected wildfire emissionst air quality worldwide
2020/10/30
In lab studies of wildfire, nitrous acid seems to be a minor actor, often underrepresented in atmospheric models. But in the real-world atmosphere during wildfires, the chemical plays a leading role.I...
77 countries committed to cut greenhouse gas emissions to net zero by 2050, while 70 countries announced they will either boost their national action plans by 2020 or have started the process of doing...

Ammonia Emissions Unlikely China Haze
2017/10/25
As China struggles to find ways to remedy the noxious haze that lingers over Beijing and other cities in the winter, researchers from Georgia Institute of Technology have cast serious doubt on one pro...
Methane-eating bacteria in lake deep beneath Antarctic ice sheet may reduce greenhouse gas emissions（图）
Methane-eating bacteria lake deep Antarctic ice sheet reduce greenhouse gas emissions
2017/9/1
An interdisciplinary team of researchers funded by the National Science Foundation (NSF) has concluded that bacteria in a lake 800 meters (2,600 feet) beneath the West Antarctic Ice Sheet may digest m...
Pity the poor plant. When faced with danger, animal species have their fight-or-flight response, but vegetation has no such option. Literally rooted in place, plants have taken defense to creative lev...
Methane-eating microorganisms help regulate emissions from wetlands
Methane-eating microorganisms regulate emissions wetlands
2015/7/13
Though they occupy a small fraction of Earth's surface, freshwater wetlands are the largest natural source of methane emitted into the atmosphere. New research identifies an unexpected process that ac...
New study: Iceberg influx into Atlantic during ice age raised tropical methane emissions
Iceberg influx into Atlantic ice age tropical methane emissions
2015/6/18
A new study shows how huge influxes of fresh water into the North Atlantic Ocean from icebergs calving off North America during the last ice age had an unexpected effect – they increased the productio...

2014/7/15
A University of Queensland scientist is involved in an international collaboration that has proposed a new strategy for marine conservation, which involves unconventional, proactive tactics, in a pape...
Researchers show major increase in CO2 emissions
CO2 emissions the world's natural 'sinks' carbon
2009/12/15
A rise in atmospheric CO2 emissions continues to outstrip the ability of the world's natural 'sinks' to absorb carbon, according to academics from the University of Sheffield, who have proved this usi...
Stalled Economy or Not, Record Year for CO2 Emissions--People Still Consumed More Per Capita in 2008（图）
Stalled Economy Record Year CO2 Emissions
2009/12/10
Each person on the planet produced 1.3 tons of carbon last year—an all-time high--despite a global recession that slowed the growth of fossil fuel emissions for the first time this decade, according t...
Professor Ernest Moniz, director of the MIT Energy Initiative (MITEI) and former undersecretary of the U.S. Department of Energy, today unveiled a report on reducing carbon dioxide emissions from exis...
