Sentences with phrase «like human aerosol»

Note that while the BEST approach is based on correlations, they are correlations of variables with known causal relationships (i.e. an increased greenhouse effect is known to cause global warming), although they do not appear to have considered some important influences like human aerosol emissions or the El Niño Southern Oscillation.

Not exact matches

Each model had run simulations that included anthropogenic climate influences like human - released greenhouse gases and aerosols as well as simulations run without those human influences.

In particular, human - induced aerosols like soot and combustion particulates actually work the opposite, reducing the amount of precipitation clouds can form.

However there are other first order drivers of climate including natural ones like solar variation and human driven ones like land use change, aerosols and soot.

Aerosols, or microscopic particles like soot or black carbon in the air, occur naturally but have also been increasing due to human activities since the industrial revolution.

The hole in the ozone layer over Antarctica was created by human - produced chlorofluorocarbons (CFCs) that came from things like aerosol cans and air - conditioners and refrigerators.

Somewhere there should also be a cost in human health bill for coal and gas — related to other aspects of fossil fuel epidemiology — like poisoning from mercury from coal emissions or asthma from aerosols from gas plants.

Natural gas produces almost no aerosol pollution, and this is good for human health and the regional environment, but for climate change could be like opening a dam full of water into the valley downstream full of people.

If we modify the first statement to include other human influences like methane and aerosols the limit of the second statement is slightly reduced, perhaps to 0.7 C.

In other words, the slowed surface warming isn't a result of a smaller global energy imbalance due to factors like increased cooling from human aerosol emissions.

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.
