talking to the green market
about the fact its low
emissions are due to French nuclear power, and while Virgin's pendolino trains claim a pretty low
carbon output, many of their other trains are still powered by dirty diesel (the UK is way behind Europe on electrification, which would cut
emissions greatly).
Holding concentrations or temperature (more remotely) to a particular target therefore means limiting cumulative
emissions of, say,
carbon over time... a limited amount of time if we are
talking about an iterative approach, and over a long period of time if we are
talking about reducing the likelihood of some very nasty consequences well after we (but not our grandchildren — if we are lucky enough to have some) are gone.
But triggering an algae bloom is also a way to suck
carbon dioxide out of the atmosphere, and along with spewing particles into the stratosphere to block some of the sun's heat, it's one of the main techniques geoengineers
talk about using if efforts to limit those
emissions ultimately fail.

about if and when China would consider peaking its
carbon emissions (see previou spost «Peaking Duck: Beijing's growing appetite for climate action «-RRB- Mr. Su basically reiterated how unfair he felt it was to

emissions at this point and that developed countries should shoot for achieving their pick as soon as possible.
You can not
talk credibly
about lowering
emissions globally if, for example, you are slow to acknowledge climate change; if you undermine calls for an effective
carbon price; and if you always descend into the «jobs versus environment» argument in the public debate.
Rud, when I
talk to those of the Progressive Left who are most concerned
about climate change, and who want the United States to become the leader in finding ways to reduce
carbon emissions, they pretty much go silent when I inform them that the EPA has legal authority under the Clean Air Act and the 2009 Endangerment Finding to do much more in placing limits on
carbon emissions than the agency is actually doing.

carbon cycle is so much greater than the human
emissions, we are
talking about a small difference between large numbers.
