Paleoclimatologist studies sea levels in a desert | Meet the "minds" behind all that climate change data | Grist
Three million years ago, during what is known as the mid-Pliocene climate optimum, Earth was a much warmer place. In fact, this period marked the most recent time during which the climate was consistently warmer than it is today for an extended period. During the mid-Pliocene climate optimum, global temperatures were as much as 5.4 degrees F above today's averages. As a graduate student, Raymo proposed that this warmth was due to higher levels of carbon dioxide in the atmosphere at the time, a hypothesis that is still being tested today.

While orbital forcings offer a fascinating window into the historical mechanisms of climate variation, Raymo emphasizes that they are overshadowed today by human-driven effects on the climate. "People sometimes ask me: 'When will the next ice age be?'" she says. "The answer is that I'm pretty sure we have already prevented it. [OK, so with CO2 at 400ppm or so, it's impossible to have an ice age?  How do we know that, and if that were true, would it be a bad thing?] Like it or not, we are now the main drivers of the climate, even though so far we've been doing it completely by accident."
Climate Lessons: Why Would You Believe This? (5 of 8) 'The effects of climate change [due to man] are already being felt in Asia and Africa.'
Once again, the sentence we have examined in context, is seen to be misleading in the light of the evidence we have shown, and does not give support for alarm and extragavant actions that in all likelihood would makes things worse for countries in Asia and Africa by crippling their economic development.

It is easy to imagine such sentences being used every week in schools throughout the world, encouraging sympathy, alarm, and dismay in children. And with what justification? I have not yet found any.
Some common sense on global warming (a guest post by R. Campbell) – Telegraph Blogs
Today, though, you’re in luck. A friend of mine called Roddy Campbell has written a most excellent and balanced article on the state of current knowledge about Man-Made Global Warming. It’s much more reasonable and fair than I would be capable of. Over to you, Roddy.
Global warming: Observing the effects of climate change so far
So I would like to see a list of documented changes to our habitat caused by global warming and the attribution studies that indicate that these changes were indeed caused or greatly exacerbated by human emissions of CO2.
Great Academics Go Along With the Pack | Climate Skeptic
Note that skeptics cannot claim to get a lot of research grants, because the alarmists control the funding. Skeptics can’t get into peer-reviewed journals, because, as the East Anglia emails make clear, a small group of alarmist scientists are blocking their publication. Mann’s research has been judged outstanding by his peers because he agrees with his peers.

In a large sense, Penn State’s only test of Mann’s ability is that he is currently a member in good standing of the small in-crowd that dominates climate science. His science is good because it comes to the right conclusions.
Might As Well Be Walking on the Sun | Climate Skeptic
This is a hilariously bad siting. It demonstrates how small things can sometimes have big effects. The MMTS sensor has a very limited cable length. This does not mean that it only comes with a short cable (begging the question of why they can’t just buy a longer one), but that it can only have a short cable due to signal amplification issues. As a result, we get this terrible siting because it needs to be close to the building, whereas even a hundred yards away there were much better locations
