Landfills represent significant anthropogenic sources of methane (CH 4 ) and carbon dioxide (CO 2 ); the main constituents of greenhouse gases (GHGs) resultant from microbial decomposition of organic waste. In
Carbon and nitrogen losses from degraded wetlands and methane emissions from flooded wetlands are both important sources of greenhouse gas emissions. However, the net-exchange dependence on hydrothermal conditions and wetland integrity remains unclear. Using a global-scale in situ database on net greenho...

Dominguez also addressed concerns that the targeted reductions in carbon intensity for fuels aren't strict enough to reduce the use of liquefied natural gas as a marine fuel, which emits greenhouse gases when burned. He said it's a “transition fuel,” o...
【题目】Scientists blame greenhouse gases for being a major cause of climate change aroundthe world. This is because greenhouse gases trap heat in the atmosphere and make theplanet warmer.Carbon dioxide is one of the major greenhouse gases. Most of this heat-trapping gasis produced through human...

The bulletin, the fourth in an annual series, explores the intricate relationship between air quality and climate. The chemical species that lead to a degradation in air quality are normally co-emitted with greenhouse gases. Thus, changes in one inevitably cause changes in the other. ...
The concentration of greenhouse gases in the atmosphere has increased rapidly due to anthropogenic activities, resulting in a significant increase of the earth’s temperature and causing global warming. These effects are quantified using an indicator suc
