According to the IPCC, the anthropogenic greenhouse gas (GHG) emissions contributing most evidently to Global Warming in terms of relative radiative forcing are CO2 , CH4 , halocarbons and N2O. CO2 emissions originate mainly from combustion of fossil fuels, and are quite well-known. However, ...
Agriculture and land use are major sources of greenhouse gas (GHG) emissions but previous estimates were either highly aggregate or provided spatial details for subsectors obtained via different methodologies. Using a model–data integration approach that ensures full consistency between subsectors, we ...
Food systems contribute one-third of global anthropogenic greenhouse gas (GHG) emissions, roughly 16.5 GtCO2e year−1from a total 54 GtCO2e year−11,2, with both pre- and post-production phases representing a high and increasing share of total emissions3. The Food and Agriculture Organizati...
Greenhouse gas emissions (GHGs) Thedirect greenhouse gas (GHG) emissions from facilities we operate (Scope 1) were 50 million tonnes on a CO2-equivalent basis in 2023, down from 51 million tonnes of CO2equivalent in 2022. The indirect GHG emissions from the energy we purchased (electricity, ...
The meaning of GLOBAL WARMING is an increase in the earth's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution. How to use global warming in a sentence.
The world's population is now over 50% urban, and cities make an important contribution to national greenhouse gas (GHG) emissions. Many cities are developing strategies to reduce their emissions. Here we ask how and why emissions differ between cities. Our study of ten global cities shows how...
Stabilizing greenhouse gas (GHG) emissions from croplands as agricultural demand grows is a critical component of climate change mitigation. Emissions intensity metrics--including carbon dioxide equivalent emissions per kilocalorie produced (`production intensity')--can highlight regions, management practices...
which may offset some warming. The lowest-emissions scenario, which assumed steep cuts in greenhouse gas emissions beginning in 2015, predicted that the global mean surface temperature would increase between 1.0 and 1.8 °C (1.8 and 3.2 °F) by 2100 relative to the 1850–1900 average. This ra...
Collectively, reservoirs created by dams are thought to be an important source of greenhouse gases (GHGs) to the atmosphere. So far, efforts to quantify, model, and manage these emissions have been limited by data availability and inconsistencies in methodological approach. Here, we synthesize reser...
Like carbon dioxide (CO2), methane is a greenhouse gas that contributes to global warming. Although its warming effect is shorter-lived, methane is much more potent than carbon dioxide. So, if you want to counteract global warming, eliminating methane emissions pays off right away. Bovaer® ...
