A commenter on the most recent edition of het's AWOGWN asks an interesting set of questions: How would temperature data have been seen during the last 10,000 years prior to the peak of each of the previous Milankovich cycles? What caused the temperature to reverse course in those cycles and why would we not expect … Continue reading What did temperatures do as the last glacial minimum ended 120K years ago?
(image info and credits) Fake skeptics of anthropogenic global warming love to set up the straw man that mainstream climate science believes that CO2 is the one and only driver of climate change.Â They can then use it in many different attacks, such as gee whiz isn't it stupid that they haven't even thought of … Continue reading Volcanos may be countering greenhouse warming
Headline of the week from NPR.Â It is worth noting that even if the Republican representative has now apologized for his remarks and admitted they were stupid either because he realizes it or because he has to, he has not changed his position on a special tax on bicycles. (h/t willard)
Over on the history of CO2 thread, that old chestnut of an issue has been raised, namely that there's this one paper in one journal, notorious for publishing anti-science papers on climate (a field well outside its focus), that has shown wild flucuations in CO2 to levels well above today's in times as recent as … Continue reading The other Beck
I have always like this graphic from Global Warming Art: It puts the current CO2 rise into sharp perspective in terms of historical flucuations, both in its magnitude and rapidity. Well, even better for impact is the video below from Youtube user CarbonTracker: Especially intriguing is watching the seasonal rise and fall, the collective breathing … Continue reading History of atmospheric CO2
A recent model study of some hypothetical effects of biological feedbacks of climate sensitivity to doubled CO2 came into the comments here. The paper was referenced in an article on the Register and is being misused as a revelation that the world is not going to warm so much after all. mandas had a good … Continue reading Climate Sensitivity: not so much?
Okay, the "Globally and Seasonally averaged" thread has grown to over 500 comments and thus reached its point of diminishing return in terms of the time it would take to read it and the utility of doing so. And while on the one hand I don't like to feed what is drifting towards to troll-like … Continue reading Global and Seasonal thread summary and continuation
Another good video from greenman: It is very discouragin to hear a 60 year old science program explaning exactly the same basics of climate change that Inhofe and half the new republican congress claim today is an IPCC hoax.
No, not how much I will write now, but the approximate value of the two pictures I will post, using standard conversion rates. (see Eli's place for source and commentary) (this one from Global Warming Art) But don't let your lying eyes and faculties of reason fool you, we are on the cusp of a … Continue reading 2000 words
Greenman's latest: Entertaiing and informative, as usual! I did not know there was a "theological" debate about CO2 levels in the atmosphere, interesting.
