Emission reductions and global dimming

From Sam Carana of Arctic News

"Damned if you do and damned if you don’t"

The calculations may differ but the point is the same as Guy McPherson’s

Stopping the planes from flying after 9/11 brought about an immediate reduction of 1C

The effects of emission reductions

With the necessary dramatic cuts in emissions, there will also be a dramatic fall in aerosols that currently mask the full warming of greenhouse gases. 

From 1850 to 2010, anthropogenic aerosols brought about a decrease of ∼2.53 K, according to a recent paper. 

In addition, more aerosols are likely to be emitted now than in 2010, so the current masking effect of aerosols may be even higher. 

Stopping aerosol release may raise temperatures by 0.4°C or 0.72°F (low) to 2.5°C or 4.5°F (high), and when stopped abruptly this may happen in a matter of weeks.
