We find a higher sensitivity of extreme events to aerosol reductions, per degree of surface warming, in particular over
the major aerosol emission regions.

It was certainly going on during the last 20 years of the 20th century, and was certainly a
major contributor to both CO2
emissions AND sulfate
aerosols during this period — a period that saw the ONLY
major runup of global temperatures that could possibly be attributed to CO2
emissions.
These scenarios presume that there are no
major volcanic eruptions and that anthropogenic
aerosol emissions are rapidly reduced during the near term.
The estimates — based on analysis of fire's impact on
emissions of carbon dioxide, nitrous oxide, and methane; albedo or the reflectivity of Earth's surface; and release of
aerosols and other particulates — suggest fire plays a
major large role in climate than conventionally believed.
The sections below give a systematic overview of the
major natural
aerosol sources and their relations to climate parameters while anthropogenic
aerosol emissions and combined
aerosols are the subject of Chapter 2.
If the
major emitters of greenhouse gases find it hard to agree on setting caps on
emissions now, what makes you think the world can agree to injecting
aerosols in the stratosphere as a solution?
Appendix II gives, in tabulated form, the values for
emissions, abundances and burdens, and, radiative forcing of
major greenhouse gases and
aerosols based on the SRES1 scenarios (Naki» cenovi» c et.
