I agree. The definition of geoengineering is “*deliberate *large-scale
manipulation of the planetary environment to counteract anthropogenic
climate change.” This comes from: Shepherd, J. G. S. et al., 2009:
Geoengineering the climate: Science, governance and uncertainty, RS
Policy Document 10/09, (London: The Royal Society).
I completely agree that global warming is the problem we have to deal
with, but calling it "geoengineering" confuses issues. Clearly humans
are causing global warming. The latest survey shows 70% of Americans
now accept this. The question we are researching is to determine the
potential benefits and risks of proposed geoengineering schemes so that
policymakers can make informed decisions in the future if we they are
tempted to implement different schemes. If it soon seems to be more
dangerous than not doing it, that will put more pressure on mitigation.

It is well said but I will observe that putting a geo-engineering
label on what we are doing to ecosystems and the climate through human
use of energy and agriculture is not in my opinion an effective
communication technique to get people to have less visceral reactions
to the topic of intentional geo-engineering. We need to recognize
that there are big differences in context in the two realms.
It is a strong point that a full evaluation of the risks of
intentional geo-engineering should also consider the climate risks
that are potentially altered by specific geo-engineering approaches.
But I think saying something like "we are already geo-engineering"
will fall on deaf ears with the broader audience that is thinking
about this subject.

I get it, and I get that intentions matter. On the other hand, we
are globally engineering and energy system (rather than a climate
system). It certainly has in aggregate geo-engineering scale, and
also individual companies operate on truly global scale. That
said, this is a form of geo-engineering, which deliberately
ignores the climate consequences. So maybe we are not
geo-engineering the Earth Climate, but we have created an energy
flux that is about 4 orders of magnitude larger than “natural”
energy fluxes flowing into the metabolism of members of a
mammalian species. We consume in the developed countries about
100 times as much energy per capita as our own metabolism
consumes, and in part because of it, we are able to attain a
population density that is hundred times higher than that of other
mammals our size. It also turns out that species of different
size have comparable energy consumption per unit area of land. We
humans have engineered a system that provides a four orders of
magnitude larger energy input.
So we are geo-engineering, and we ignore the consequences on the
climate.
