Sentences with phrase «offsetting human emissions of greenhouse gases»

In other words, the EF defines carbon uptake in forests as the single mechanism for offsetting human emissions of greenhouse gases from industrial activity to the atmosphere.

Not exact matches

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.

Thus it is entirely unsurprising that these short - term effects all aligning in the cooling direction in recent years have offset much of the surface warming caused by human greenhouse gas emissions.

All of these studies find that humans are responsible for close to 100 % of the observed global warming over the past 50 years, and human greenhouse gas emissions are responsible for close to 150 % of the observed warming, with human aerosol (sulfur dioxide - SO2) emissions offsetting approximately one - third to one - half of that greenhouse warming.

So, in order to trigger another LIA, a new grand solar minimum would have to cause about 1 °C cooling, plus it would have to offset the continued human - caused global warming of 1 to 5 °C by 2100, depending on how our greenhouse gas emissions change over the next century.

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).
