Sentences with phrase «by human aerosol emissions»

If we add in the warming effects of the other long - lived greenhouse gases, the best estimate rises to 1.22 °C surface warming caused by human emissions (we've only observed ~ 0.8 °C warming because much of that has been offset by human aerosol emissions).

And exactly how much global warming is being offset by human aerosol emissions?

Not exact matches

The warming commitment if we stop all human emissions (GHG and aerosol) is probably very substantial: The cooling effect of the aerosol will very quickly disappear, thereby «unmasking» the greenhouse warming, approximately half of which has been canceled by aerosol cooling up to now.

Human aerosol emissions are also offsetting a significant amount of the warming by causing global dimming.

Analyses of the ground and aircraft data performed by Setyan et al. (2012), Shilling et al. (2013), and Kleinman et al. (2016) showed that organic aerosol production increased when human - caused emissions from Sacramento mixed with air rich in isoprene, an organic compound wafting from many plants that originate in the area's foothills.

Greenhouse gases can be attributed to about 0.9 °C of this warming, but it has been partially offset by about 0.3 °C cooling from human aerosol emissions.

To slow the rate of anthropogenic - induced climate change in the 21st century and to minimize its eventual magnitude, societies will need to manage the climate forcing factors that are directly influenced by human activities, in particular greenhouse gas and aerosol emissions.

This result shows, for 160 years, the GMT pattern (the climate) has not been affected by human CO2 emission, volcanoes and aerosols!

The warming commitment if we stop all human emissions (GHG and aerosol) is probably very substantial: The cooling effect of the aerosol will very quickly disappear, thereby «unmasking» the greenhouse warming, approximately half of which has been canceled by aerosol cooling up to now.

The identification of other, sometimes more powerful, greenhouse gases such as methane, the contributions to atmospheric carbon dioxide from other human activities such as deforestation and cement manufacture, better understanding of the temperature - changing properties of atmospheric pollution such as sulphur emissions, aerosols and their importance in the post-1940s northern hemisphere cooling: the knowledge - base was increasing year by year.

Radiative forcing is a way to quantify an energy imbalance imposed on the climate system either externally (e.g., solar energy output or volcanic emissions) or by human activities (e.g., deliberate land modification or emissions of greenhouse gases, aerosols, and their precursors).

Warming from decade to decade can also be affected by human factors such as variations in the emissions, from coal - fired power plants and other pollution sources, of greenhouse gases and of aerosols (airborne particles that can have both warming and cooling effects).

The failure to actually reduce global emissions has meant that all possibilities are now on the table, including some that sound like premises from a science - fiction novel: Humans could sequester carbon dioxide by removing it from the air through technologies that mimic trees, or we could spray water droplets in the lower atmosphere to reflect light and heat back to space, or we could seed sulfur aerosols in the stratosphere to do the same.
