    Well at least they're making public what they don't know. Of course more legitimate scientists have known about the "problem" for a very long time.

    There are quite literally hundreds more articles on clouds but these (and the links they have) will get you started quite nicely.

    Since when has Watts been a legitimate scientist?

    Perhaps Dr. Spencer should have a look at the fact that there was also a La Nina and a solar minumum going on at the same time. And even then, 2008 was still only the tenth warmest year on record.

    And of course, you'll have no trouble showing us in a laboratory setting how a 67% increase in CO2 caused the warming, right?

    Not at all, thank you.

    Hmmmmm, lets see....the author of the first article is Dr. Henrik Svensmark and this is his wiki bio for the research impaired. Looks like a pretty legit scientist to me.

    Henrik Svensmark is director of the Center for Sun-Climate Research at the Danish Space Research Institute (DSRI), a part of the Danish National Space Center. He previously headed the sun-climate group at DSRI. He held postdoctoral positions in physics at three other organizations: University of California, Berkeley, Nordic Institute for Theoretical Physics, and the Niels Bohr Institute.[1]

    In 1997, Svensmark and Eigil Friis-Christensen popularised a theory that linked galactic cosmic rays and global climate change mediated primarily by variations in the intensity of the solar wind, which they have termed cosmoclimatology. This theory had earlier been reviewed by Dickinson.[2] One of the small-scale processes related to this link was studied in a laboratory experiment performed at the Danish National Space Center (paper published in the Proceedings of the Royal Society A, February 8, 2007).

    Svensmark's research downplays the significance to which atmospheric CO2 has affected recent global warming.

    Reporting from a legit scientist. I would assume that's OK with you seeings's how you do it all the time. Or do you follow a different set of rules?

    Almost all studies since then can find little to link cosmic rays and global warming.

    Cosmic Rays Do Not Explain Global Warming, Study Finds

    Unlikely that cosmic rays affect global warming

    There are scientific uncertanties about cosmic rays and cloud formation. Some researchers have claimed that a reduction of cosmic rays during the last decades has contributed to the global temperature rise. The hypothesis is that fewer cosmic rays causes fewer cloud droplets and reduced droplet size, and that this again causes global warming, since reduced cloud droplets would reflect less energy from the sun back to space. However, the researchers who stick to this hypothesis find little support amongst colleagues.

    “According to our research, it does not look like reduced cosmic rays leads to reduced cloud formation”, says Jon Egill Kristjansson, a professor at the University of Oslo.

    This result is in line with most other research in the field. As far as Kristjansson knows, no studies have proved a correlation between reduced cosmic rays and reduced cloud formation.

    Kristjansson also points out that most research shows no reduction in cosmic rays during the last decades, and that an astronomic explanation of today’s global warming therefore seems very unlikely
