Turning carbon emissions into rocks（图）
碳排放 岩石 清洁能源 气候学
2023/7/7
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....
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Reevaluation of the carbon emissions embodied in global value chains based on an inter-country input-output model with multinational enterprises
跨国企业 国家间 投入产出模式 全球价值链 碳排放
2023/5/9
Multinational enterprises actively participate in global production networks. However, the current global value chain accounting framework fails to consider the emissions originating from the producti...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The emissions responsibility accounting of multinational enterprises for an efficient climate policy
跨国企业 排放责任核算 高效气候政策
2023/5/9
The achievement of global warming limits below 2 °C and 1.5 °C requires deeper involvement of nonstate and subnational actors. In this paper, we focus on multinational enterprises (MNEs) and propose a...
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...
Losses of eelgrass beds give rise to large emissions of carbon and nutrients
eelgrass bed ecosystem eutrophication nitrogen
2021/8/5
Losses of important eelgrass meadows in western Sweden since the 1980s have led to considerable bottom erosion and the release of carbon and nitrogen; substances that contribute to increasing climate ...
Extraordinary carbon emissions from El Nino-induced biomass burning estimated
El Nino carbon emission carbon dioxide
2021/8/3
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...
Asymmetry in CO2 emissions and removals could skew climate targets
carbon dioxide emissions climate targets carbon dioxide removals
2021/8/4
Changes in climate resulting from carbon dioxide (CO2) emissions into the Earth's atmosphere are not equal to the climate changes from deliberate CO2 removals -- and assuming such a balance could lead...
Urban rivers are hotspots of riverine greenhouse gas (N2O, CH4, CO2) emissions in the mixed-landscape chaohu lake basin
Urban rivers greenhouse gas GHG Global warming
2021/7/27
Growing evidence shows that riverine networks surrounding urban landscapes may be hotspots of riverine greenhouse gas (GHG) emissions.
Unexpected wildfire emissions impact air quality worldwide（图）
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...
第34届国际湖沼学大会专题6：浮游生物动态对内陆水体甲烷通量和排放的影响（Effects of plankton dynamics on methane fluxes and emissions from inland waters）
第34届 湖沼学大会 浮游生物动态 内陆水体甲烷通量 排放影响
2018/1/20
Natural and man-made inland waters represent globally significant sites of methane production and emit annually about 100 Tg of this potent GHG to the atmosphere. On the other hand, a large fraction o...
第34届国际湖沼学大会专题1：碳循环和水库温室气体排放（Carbon cycling and greenhouse gas emissions in reservoirs）
第34届 国际湖沼学大会 专题 碳循环 水库温室 气体排放
2018/1/18
Reservoirs are environmental reactors that receive and process large amounts of carbon from their catchments and from the organic matter flooded during the impoundment process. Part of the ensuing emi...

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...
