  • models suggest that cut may also have cut into the warming of the state's climate in an unexpectedly big way, preventing temperatures from climbing even higher.
  • "This indeed has major implications for mitigating climate change on a global scale," says Ramanathan. "We have the chance to see a quick global response."

    I know at least of a few people who share this point of view :)

    I think it is worth noting that Dyson's is not saying that climate change is an illusion - it is evident that a lot of CO2 is emitted into the atmosphere and hence something will change. His point is that we just don't know what will change and by how much and that (much) more experimental data is necessary to make predictive models.

    On missing experimental work: just read in the news that condensation in cirrus clouds has been studied recently and that the models where incorrect as to what the significance of organic substances and soot is in cirrus cloud formation. http://www.sciencemag.org/content/early/2013/05/08/science.1234145

    http://www.nature.com/news/2010/101022/full/news.2010.558.html hmm should be the ACT in Nature, no? ;)

    Yeeesss :) So the "non-commercial" rockets do not emit soot? And how many "non-commercial" launches per year are there in comparison to the commercial ones? Finally commercial space-flight seems more realisable than ever, and "non-commercial" guys will do everything to prevent situation in which they have to compete on an open market... Coming years should be very interesting...

    Some bacteria can influence the weather. Up high in the sky where clouds form, water droplets condense and ice crystal grow around tiny particles. Typically these particles are dust, pollen, or even soot from a wildfire. But recently scientists have begun to realize that some of these little particles are alive - they are bacteria evolved to create ice or water droplets around themselves. old but might be worth a discussion
