Turning carbon emissions into rocks（图）
碳排放 岩石 清洁能源 气候学
2022/12/15
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...
Extraordinary carbon emissions from El Nino-induced biomass burning estimated
El Nino carbon emission carbon dioxide
2021/7/15
In 2015, massive biomass burning events occurred in Equatorial Asia which released a large amount of carbon into the atmosphere, whose signals were captured by in-situ high-precision measurements onbo...
Unexpected wildfire emissions impact air quality worldwide（图）
Unexpected wildfire emissionst air quality worldwide
2020/9/27
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
2017/10/3
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...
New study: Iceberg influx into Atlantic during ice age raised tropical methane emissions
Iceberg influx into Atlantic ice age tropical methane emissions
2015/5/28
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...
Researchers show emissions from forests influence very first stage of cloud formation
emissions from forests influence first stage cloud formation
2014/5/15
PITTSBURGH—Clouds play a critical role in Earth's climate. Clouds also are the largest source of uncertainty in present climate models, according to the latest report of the Intergovernmental Panel on...
The discovery of a new form of microbial life that can consume the potent greenhouse gas methane has earned University of Queensland (UQ) researchers a place in the prestigious journal Nature.
Emissions of Organic Compounds in Surfactant Solutions under Air Turbulence
Volatilization rate Volatilization reduction Surfactants Wind Interface concentration
2012/8/25
The objective of this study was to investigate the effects of surfactants aggregating the gas-liquid interface on the
volatilization rates of the organic compounds. The changes in the overall mass tr...

Air quality the Yangtze River Delta, China
2011/2/21
Regional trans-boundary air pollution has become an important issue in the field of air pollution modeling. This paper presents the results of the implementation of the MM5-CMAQ modeling system in the...
Sensitivity of stratospheric Bry to uncertainties in very short lived substance emissions and atmospheric transport
stratospheric Bry lived substance emissions atmospheric transport
2011/2/16
We evaluate the sensitivity of Bry entering the stratosphere with a simplified model that allows calculations over a wide parameter range for parameters that are currently poorly quantified. The model...
