Because fighting terrorism is taking actions to seek out and kill those who would perpetrate it.. I certainly hope he doesn't seek to exterminate all of us who emit CO2 and Methane.. Because that would result in the extermination of all life on this planet as well; a seeming contradiction to what he claims to be trying to preserve. Global warming is a challenge to restore a somewhat stable balance to the planet's environment. And given the paleo-climatic history of the planet, the environment is ANYTHING BUT STABLE.. There have been periods of extreme warming and cooling long before the advent of mankind and industrialization. Thus, what we REALLY are trying to do is thwart the planet's natural cycles to maintain the climatic "status quo". That's also known as "geo-engineering"... (and I'm not particularly opposed to it). And the best means of accomplishing that is by facilitating the planet's natural means of sequestering CO2 by the cultivation of oceanic phytoplankton blooms via natural/organic nutrient fertilization. The oceans, not the rain forest, are the true "lungs" of this planet. And by increasing the ocean's ability (via phytoplanktonic fertilization) to absorb CO2, we will be able to offset most increases in CO2 levels (whether natural or man-made). One of the "dirty little secrets" in the debate over increasing CO2 levels is that phytoplankton levels in the oceans have been diminishing for decades. Thus, even IF we manage to decrease CO2 emissions, it will have to outpace the decreasing ability of the oceans to absorb it. In sum, every year phytoplankton levels decrease in the oceans due to lack of micronutrients, the "balance" we're seeking to restore becomes harder to achieve. Decreasing man-made CO2 emissions is all well and good, but without increasing levels of oceanic phytoplankton, we may find our efforts in vain. And one more beneficial consequence of increasing phytoplankton levels is that it augments the foundation of the marine food chain. And scientific evidence has clearly shown that our fisheries are quickly being depleted as well. Yet, any efforts at advancing research of oceanic fertilization is ostracized by the global warming scientific community. It's called "geo-engineering".. the very thing we're trying to do by aiming at climatic "stability" in an historically unstable paleo-climatic record. As a final note, I might add that Bloomberg failed to discuss an already existing technlogy that is woefully underfunded, the creation of alternative fuels via Algae farming. No one seems to want to mention it, despite the fact than acre of algae could produce upwards of 5,000 gallons of bio-diesel per year (compared to 300 gallons of ethanol from an acre of corn, or 60 barrels of bio-diesel from an acre of soybeans). And the one advantage of producing fuel from algae is that it does not compete with human food consumables.ngm.nationalgeographic.com ngm.nationalgeographic.com Hawk
