US Scientists Launch World's Biggest Solar Geoengineering Study (theguardian.com)

In what will be the world's biggest solar geoengineering program to date, U.S. scientists part of the $20 million Harvard University project are going to send aerosol injections 20km (~12.4 miles) into the earth's stratosphere "to establish whether the technology can safely simulate the atmospheric cooling effects of a volcanic eruption," The Guardian reports. From the report: Scientists hope to complete two small-scale dispersals of first water and then calcium carbonate particles by 2022. Future tests could involve seeding the sky with aluminum oxide -- or even diamonds. Janos Pasztor, Ban Ki-moon's assistant climate chief at the UN who now leads a geoengineering governance initiative, said that the Harvard scientists would only disperse minimal amounts of compounds in their tests, under strict university controls. Geoengineering advocates stress that any attempt at a solar tech fix is years away and should be viewed as a compliment to -- not a substitute for -- aggressive emissions reductions action. But the Harvard team, in a promotional video for the project, suggest a redirection of one percent of current climate mitigation funds to geoengineering research, and argue that the planet could be covered with a solar shield for as little as $10 billion a year. Some senior UN climate scientists view such developments with alarm, fearing a cash drain from proven mitigation technologies such as wind and solar energy, to ones carrying the potential for unintended disasters. If lab tests are positive, the experiment would then be replicated with a limestone compound which the researchers believe will neither absorb solar or terrestrial radiation, nor deplete the ozone layer.

    This is a massive waste of money, and it's dangerous. When you move past the "adjustments" (fabrications) to climate data, there's no evidence the Earth is getting warmer. In fact, the Earth has been cooling slightly for the past few decades. Climate scientists have stated that sea ice is decoupled from global average temperates when they said that Antarctic sea ice would grow as the Earth warms. In the longer term, we're likely to descend back into another ice age, based on natural cycles. We actually need the Earth to be warm in order to support human civilization. Accelerating the process of global cooling is probably going to be incredibly damaging to human life. It's a waste of money because it's attempting to solve a problem that doesn't exist. It's also extremely dangerous. Let's not destroy human civilization because we believed the global warming lies. I'm certain I'll be modded down by moderators who are eager to censor my views, but that just underscores how Slashdot readers and scientists don't care about the truth and would prefer to silence it.

    The proposed scheme reduces Earth's infrared energy surplus by reducing the amount of visible light reaching us from the sun. Photosynthesis requires certain wavelengths of visible light; so reducing the amount of sunlight reaching plants will reduce photosynthesis, which will in turn reduce the conversion rate of CO2 to O2. So while less energy comes into the system, more CO2 remains in the system, and the latter will tend to offset the former. The net effect on warming might be zero. Worse, we could be upside-down on the transaction, with the net effect actually worsening global warming in the long term. Yes, volcanic eruptions reduce average temperatures; but their effects are fairly short-lived, and don't give us much of a clue about the consequences of reducing the amount of sunlight reaching the Earth's surface over a span of decades or centuries. Also, it strikes me that we might experience significantly-reduced crop yields as an additional result of the reduced photosynthesis - not a good thing when we may also be losing arable land as a result of rising sea levels.

    I really hope the folks tinkering with our biosphere are asking the same questions, (and more), and coming up with credible answers. I know they're generally a smart lot of people; but their track record so far WRT climate change models and predictions isn't nearly good enough to justify their apparent excess of hubris.

      Because if it works, we might pat ourself in the back, go on doing business as usual, and declare the problem solved, and indeed that would be in some sense appropriate, since the problem would be solved at least partially (leaving alone ocean acidification and other problematic things).

      BUT then at that point sustaining the effort becomes a big unbreakable international COMMITMENT. And if for ANY reason we stop sustaining the scheme after several decades, we will, in the span of only a few years, get several decades worth of warming, at that will probably way more lethal since if the warming happens gradually we (and life on earth) will have a marginal chance to adapt, but if a lot of warming happens very fast, then adaptation chances would be way reduced, and consequences potentially catastrophic and lethal for the whole ecosystem including us.
