Either way this stuff should be "last resort" only.

Bill Gates backs climate scientists lobbying for large-scale geoengineering
Other wealthy individuals have also funded a series of reports into the future use of technologies to geoengineer the climate
A small group of leading climate scientists, financially supported by billionaires including Bill Gates, are lobbying governments and international bodies to back experiments into manipulating the climate on a global scale to avoid catastrophic climate change.
The scientists, who advocate geoengineering methods such as spraying millions of tonnes of reflective particles of sulphur dioxide 30 miles above earth, argue that a "plan B" for climate change will be needed if the UN and politicians cannot agree to making the necessary cuts in greenhouse gases, and say the US government and others should pay for a major programme of international research.
Solar geoengineering techniques are highly controversial: while some climate scientists believe they may prove a quick and relatively cheap way to slow global warming, others fear that when conducted in the upper atmosphere, they could irrevocably alter rainfall patterns and interfere with the earth's climate.
Geoengineering is opposed by many environmentalists, who say the technology could undermine efforts to reduce emissions, and by developing countries who fear it could be used as a weapon or by rich countries to their advantage. In 2010, the UN Convention on Biological Diversity declared a moratorium on experiments in the sea and space, except for small-scale scientific studies.Although I agree with the sentiment, that is rather rich, coming as it does from someone backed by the entire U.S. Government, bureaucracies full of interests, conflicted and vested.
Concern is now growing that the small but influential group of scientists, and their backers, may have a disproportionate effect on major decisions about geoengineering research and policy.
"We will need to protect ourselves from vested interests [and] be sure that choices are not influenced by parties who might make significant amounts of money through a choice to modify climate, especially using proprietary intellectual property," said Jane Long, director at large for the Lawrence Livermore National Laboratory in the US, in a paper delivered to a recent geoengineering conference on ethics....MORE
As President Eisenhower said in his Farewell Address, after that bit about the Military-Industrial Complex:
...Akin to, and largely responsible for the sweeping changes in our industrial-military posture, has been the technological revolution during recent decades.
In this revolution, research has become central; it also becomes more formalized, complex, and costly. A steadily increasing share is conducted for, by, or at the direction of, the Federal government.
Today, the solitary inventor, tinkering in his shop, has been overshadowed by task forces of scientists in laboratories and testing fields. In the same fashion, the free university, historically the fountainhead of free ideas and scientific discovery, has experienced a revolution in the conduct of research. Partly because of the huge costs involved, a government contract becomes virtually a substitute for intellectual curiosity. For every old blackboard there are now hundreds of new electronic computers.
The prospect of domination of the nation's scholars by Federal employment, project allocations, and the power of money is ever present--and is gravely to be regarded.Something to think about.
Yet, in holding scientific research and discovery in respect, as we should, we must also be alert to the equal and opposite danger that public policy could itself become the captive of a scientific-technological elite....

How to Trigger an Ice Age the Easy Way, Killing Billions of People
The secret to killing billions and billions of people without being too obvious about it, is to make it difficult or impossible to grow enough food to feed them. Geological history demonstrates that the best way of doing this -- short of a global thermonuclear war -- is by triggering a global ice age. If winters are too long and summers are too short and cold, crops cannot be grown, and livestock will starve. Without enough food, billions of people will die, until there are only enough people to match the dwindling food supplies.See also:
