Michael Mann implies that skeptics might have weaponized anthrax and would commit bioterrorism | JunkScience.com

Watch for the butterfly net to overtake the hockey stick in global warming symbolism.

Note how Mann’s phony anthrax attack segues into claims about tobacco industry tactics to discredit and intimidate scientists.

PSU Climatologist Michael Mann answering questions often raised by climate skeptics, warning against intimidation of scientists

[Mann] It's due to fossil fuel emissions and rising greenhouse gas concentrations. That conclusion has actually been established by taking models, theoretical models of the climate and subjecting them both to natural factors like volcanic eruptions and changes and the behaviour of the sun and the human factors of increasing greenhouse gas concentrations and what those more recent studies show is that you can't explain that anomalous recent warming from natural factors. We can only explain it when we include the effect of humans on the climate.
...[Mann] Yeah, so both in our estimates and many other estimates of how temperatures have changed in the past, we do see about 1,000 years, a period of relative warmth. Not warmth that actually rivals the most recent decades. The most recent warming takes us outside of that range of the past warmth. But there was an interval of time about 1,000 years ago that was little warmer than the colder interval that we call the Little Ice Age which took place several centuries later. Now we can actually explain that period of moderate temperatures 1,000 years ago based on natural factors. A fairly high amount of solar activity, so the sun was a little bit brighter; there were relatively few volcanic eruptions, which are a cooling influence on the climate. So when we put those natural factors into the climate, we can actually explain that relatively warm medieval period.

Die Klimazwiebel: Excitement around Climate of the Past

One of the most negative breaches of the review process that we have seen pictured in the Climate Gate emails was the attempt by reviewers to agree on negative reviews, with the stated goal of bringing down a particular manuscript.

End Of March : Ponds Frozen | Real Science

I noticed this afternoon that most of the ponds are frozen over here in Fort Collins. That is unheard of this late in the spring. We didn’t make it above freezing all weekend.

The Arctic however is ice-free.
