The Royal Society Proposes First Framework For Climate Engineering Experiments

Jason Koebler writes The Royal Society of London, the world's oldest scientific publisher, has unveiled a proposal to create the first serious framework for future geoengineering experiments. It's a sign that what are still considered drastic and risky measures to combat climate change are drifting further into the purview of mainstream science. The scientific body has issued a call to create "an open and transparent review process that ensures such experiments have the necessary social license to operate."

    DO NOT DO THIS. If it works and you overshoot, you'll induce another ice age, which can happen in as few as a couple of years. Unlike moving in from the oceans over 100-300 years (a nuisance, and less damaging to human life than slowing technological advancement by massive intervention in the economy) an ice age will indeed, and actually, and rapidly kill billions of people.

      I should think that any geo-engineering attempt to reduce atmospheric CO2 would have to be on a massive scale - there will be plenty of time for the anxious to voice their concerns and present their evidence.

      Besides, if anything I think we've been far TOO consultative through this process. We spent what? 30 years listening to denialists and waiting for them to produce some evidence for their theory (that anthropogenic CO2 does not cause warming unlike natural CO2 which is mysteriously different).

We may have crossed some other lines to do with the Indian monsoon, the African monsoon, the savannahization of the amazon rainforest and the collapse of the boreal forests.

      No one wants to do geoengineering, except those with an interest in the fossil fuel industry. But the time to reduce emissions was 20 years ago, and while reductions now will make for savings, the consequences of what we have already done are likely horrific in terms of biodiveristy and displacement and starvation of vulnerable peoples.

      So it needs to be on the table. Open and transparent is very important, but I think that there'll be plenty of interest in making sure that concerns are considered.

      And the inertia will be all towards caution in this case, (again barring people with an interest in the fossil fuel industry). Geo-engineering may have benefits for the entire world if it ameliorates AGW, but it also has to be funded.

      There has been plenty of warming in the last 17.5 years. The warming of the surface air temperature has been marginal, (but not statistically significantly "no warming" as you appear to be claiming.) The best you can correctly and scientifically say, is that there might be a reduction in the rate of warming of the surface air temperature.

      The oceans have warmed. As can be seen from the direct measurements, if you're into science, but if you're not, it's clear and obvious from sea level rise which is primarily thermal expansion.

      Ice sheets have lost mass.

      re: They make models that show doom, and don't match up with reality.
      No they don't. They make models that investigate the climate.

      Some aspects match with reality well. Some aspects require finer modelling. (And there are probably some physical processes that are not fully understood either, especially with respect to cloud formation).

      Sure, all (I think) models have a double-Intertropical Convergence Zone. That doesn't mean that they aren't useful. Quite the opposite. The most exciting phrase to hear in science, the one that heralds the most discoveries, is not "Eureka!" but "That's funny...". And so work on the DICZ progresses. Science advances. We learn more stuff.

      Claiming "Models don't match reality! All this science must therefore be rubbish!" is the call of the Luddites. Einstein didn't overthrow Newton, he built upon his work, and Newton did upon the giants upon whose shoulders he stood. This is how science works.

    In light of reporting in the July-August issue on Harvard’s position on fossil fuel divestment, we wrote Messrs. Paul J. Finnegan and James F. Rothenberg [members of the Harvard Corporation, and Treasurer and past Treasurer, respectively], expressing the perspective summarized below.

    Harvard currently holds substantial investments in fossil fuel. The past is no longer prologue for this asset class.

    The scientific community—including Harvard’s distinguished climate-related faculty—assert the world must hold global temperatures to no more than 2 degrees C above the preindustrial figure. Governments agree. And, yet, we have already gone half the distance to this ceiling, and are actually accelerating our rapid approach to it. We face an existential planetary threat.

    By investing in fossil fuel companies that cling to the outdated business model of measuring success by discovery of new reserves, Harvard is encouraging (and expecting to profit from) the search for more fossil fuel—which will become unburnable if we stabilize global temperatures at levels necessary to sustain life as we know it. When the lid is put on, and carbon emissions are severely limited—as they must be—Harvard will be left holding stranded and devalued assets that can never be burned. (Proven reserves are three to four times what’s needed to transition to renewables by 2050.)

    Across the country, hundreds of student organizations work to persuade their institutions’ endowments to divest. Sooner or later, as in the case of companies doing business in apartheid South Africa, divestment from fossil fuel companies will occur. Harvard should be among the first to do so. There are strong, independently sufficient arguments beyond the financial one of stranding to justify divestment. They include the moral (it is repugnant to profit from enterprises directly responsible for carbon emissions or to allow shareholder funds to be deployed in searching for more fossil fuel), the practical (a well-led institution should not wound itself by permitting endowment holdings to demoralize faculty and students, with adverse effects on quality of education, enrollment, and campus environment) and, in Harvard’s case, the unique opportunity (and corresponding duty) it has, as one of a handful of world leaders in education, to lead on this planetary issue.

    We support these other arguments for divestment. However, we wanted to bring the financial argument, in particular, to Harvard’s attention. Over the past three years, equities in the coal industry declined by over 60 percent while the S&P 500 rose by some 47 percent. Coal, we submit, is the “canary in the oil well.” Disinvestment now, before this opinion becomes commonplace, is just sound, risk-averse investment judgment, fitting well within the duties of a fiduciary.

    So this is where I personally opt out.
            I will deny climate change simply in an effort to keep people from screwing with the planet and to encourage others to protest experiments.
            My next house will have two airconditioners, four cars (all SUV's), two pools, and as much 'always on' electronic gadgetry as I can stuff in it.
            All my future purchases will be quadruple wrapped in plastic, all my food processed, and I'll no longer recycle.

    If you're going to engineer the planet, I'm going to make it worth your while.
