Roger Pielke Sr, a genuine, respected climate scientist, has a bit to say about the new Doomsday Clock including global warming:

This type of news perpetuates the misinformation on the issues of climate to the public. Statements such as, “This is the first time it has included climate change as an explicit threat to the future of civilisation”, are not consistent with any existing climate assessment.
Claims such as, “”Whether it’s a threat of the same magnitude or slightly less or greater is beside the point,” said Michael Oppenheimer, a geoscientist from Princeton University, US,” have absolutely no basis in the published climate science literature.

Indeed. You can search those 1000 scientific articles Al Gore quotes for reference to climate change as a threat to civilization and you won’t find one.

Oh, and if you want a peer-reviewed article questioning alarmism that Gore says doesn’t exist, here’s today’s example (PDF link):

[I]f CO2 concentration remains constant at present, the CO2 greenhouse effect will be deficient in counterchecking the natural cooling of global climate in the following 20 years. Even though the CO2 greenhouse effect on global climate change is unsuspicious, it could have been excessively exaggerated. It is high time to re-consider the trend of global climate changes.

Nope. Doesn’t exist. Please move on. Nothing to see here.
