Page 19: Research news on greenhouse gases
Greenhouse gases are atmospheric constituents that absorb and emit infrared radiation, thereby contributing to the greenhouse effect and Earth’s radiative energy balance. Major greenhouse gases include carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), ozone (O₃), and various halogenated compounds, along with water vapour (H₂O) as a feedback agent. Their radiative forcing depends on concentration, spectral absorption properties, atmospheric lifetime, and overlap with other absorbers. In climate research, greenhouse gases are quantified via metrics such as global warming potential and effective radiative forcing to assess their contribution to anthropogenic climate change and to inform emissions mitigation strategies.
A new global map uses a fleet of satellites to catch methane leaks from the energy sector
When it comes to global warming and greenhouse gases, methane is one of the bad guys. It's the second most important contributor to climate change after carbon dioxide. However, quantifying the exact amount being released ...
Satellites help tackle landfill methane leaks
Satellites are emerging as a powerful new tool in the fight to curb emissions of methane. While methane is much shorter-lived in the atmosphere than carbon dioxide, it is vastly more potent at trapping heat, which makes rapid ...

A new framework addresses fair distribution of emissions
Ten years ago, on 12 December 2015, the Paris Climate Agreement was signed at the UN Climate Conference. In order to limit global warming to well below two degrees, only a certain amount of CO2 may be emitted worldwide. While ...

Greenhouse gases projected to sharply increase extreme flooding in Central Himalayas
Rising greenhouse gas emissions could see the size of extreme floods in the Central Himalayas increase by between as much as 73% and 84% by the end of this century.

When companies 'go green,' air quality impacts can vary dramatically
Many organizations are taking actions to shrink their carbon footprint, such as purchasing electricity from renewable sources or reducing air travel. Both actions would cut greenhouse gas emissions, but which offers greater ...

Degraded peatlands emit nearly twice as much greenhouse gas as previously thought, study finds
For the first time, researchers have produced a detailed, high-resolution map of peatlands in the EU, showing that these areas emit twice as much greenhouse gases than previously thought. The research, led by eco-hydrologist ...

24,000 times more harmful to the climate than CO₂: Measurements reveal SF₆ gas emissions in Germany
Sulfur hexafluoride (SF6) is a chemically stable, colorless, odorless, and non-toxic gas. It is used all over the world, primarily as an insulating and protective gas in electrical switchgear within medium- and high-voltage ...

Emissions from global wildfires far higher than previously thought
The total emissions of greenhouse gases and airborne particles caused by wildfires are almost 70% higher than previously assumed. Researchers at Wageningen University & Research discovered this in a long-term study conducted ...
