Emissions reductions are also needed, but by themselves they cannot achieve their goal

There are two basic plans for responding to global warming: emissions reductions alone, and geoengineering alongside emissions reductions.
Geoengineering -- blocking up to 2% of incoming sunlight -- was the main plan for dealing with global warming in the Federal Science report of 1965. However, a few years later the New Left Movement, with its ideological orientations against technology and the West, captured environmentalism. It excluded geoengineering from the global warming discussion, which came to be confined exclusively to cutting greenhouse emissions.
