Detection of climate change, attribution of causes, and projections

Question 1

Using what estimates strongly suggests that anthropogenic GHG’s are affecting climate
(particularly in the past few decades).

Answer 1

Radiative forcing of pollutant gases, volcanic emissions, and solar variability, models approximate the observed data best when all three
forcing factors are included.

Question 2

Where are anthropogenic aerosols such as – sulphur particulates and other particulates such as soot found?

Answer 2

In the troposphere

Question 3

An indirect effect of aerosols is to…

Answer 3

act as condensation nuclei for water vapour within clouds, increasing the number of small droplets, which makes clouds more reflective and which also exerts a cooling.
