Remember – there’s really no dispute over the evidence that catastrophic anthropogenic climate change is underway. All the models predict it; the science is solid; the consensus is broad and unshakable.

Oh, and pay no attention that significant downward revisions have had to be made in recent US temperature data:

Climate scientist Michael Mann (famous for the hockey stick chart) once made the statement that the 1990’s were the warmest decade in a millennia and that “there is a 95 to 99% certainty that 1998 was the hottest year in the last one thousand years.” (By the way, Mann now denies he ever made this claim, though you can watch him say these exact words in the CBC documentary Global Warming: Doomsday Called Off).

Well, it turns out that according to the NASA GISS database that 1998 was not even the hottest year of the last century. Many temperatures from recent decades that appeared to show substantial warming have been revised downwards.

A good deal of interesting information in that post – read the whole thing. Via Q and O.

A climatologist reflects on his visit to AGU’s conference last week. Salient bit here:

What I see is something that I am having a hard time labeling, but that I might call either a "hangover" or a "sophomore slump" or "buyers remorse." None fit perfectly, but perhaps the combination does. I speak for (my interpretation) of the collective: {We tried for years – decades – to get them to listen to us about climate change. To do that we had to ramp up our rhetoric. We had to figure out ways to tone down our natural skepticism (we are scientists, after all) in order to put on a united face. We knew it would mean pushing the science harder than it should be. We knew it would mean allowing the boundary-pushers on the "it’s happening" side free reign while stifling the boundary-pushers on the other side. But knowing the science, we knew the stakes to humanity were high and that the opposition to the truth would be fierce, so we knew we had to dig in. But now they are listening. Now they do believe us. Now they say they’re ready to take action. And now we’re wondering if we didn’t create a monster.

Read the whole thing. I wonder when this will spread among anti-global warming Evangelicals. (hat tip)

[UPDATE: Goldberg at the Corner invokes a variation on the skepticism theme: "Anti-clericalism was certainly partly driven from the suspicion that priests and other clergy were preaching their versions of the gospel simply to empower themselves. I've long argued that one of the reasons Washington-based reporters are liberal, or statist, is that if the subject they cover is considered hugely important, then they in turn will be considered hugely important." A reader responds with Cui bono.]

If climate scientists ever wonder why they are looked upon with suspicion among some people in society, they need look no further in their willingness to compromise their own intellectual standards in policy debate on the issue of disasters and climate change.

What he’s saying is that the scientific method involves both establishing an hypothesis, and making a diligent effort towards disproving that hypothesis to see whether one’s original assumptions still hold up.

I’m not sure many of the outstpoken global warming moralists in evangelical circles today get this. That’s because people of faith don’t normally operate like this.

Other than notables like McDowell who found Christ while trying to disprove him, Christians are geared from children’s church onward to absorb and apply church doctrine based on the concerted studies of biblical authorities, or in the case of Scripture, first-hand witnesses inspired by the Holy Spirit. While we might critically analyze biblical truth as it applies to our lives today, we rarely set ourselves toward disproving the Bible itself as a way to establish it’s veracity.

There is an important distinction, then, between aggressively promoting environmental stewardship as a God-ordained moral ethic (which it is), and aggressively promoting a particular area of human-derived environmental science as a moral ethic (which it is not).

Being salt and light in the world means making this distinction evidently clear to all.

Beloved, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world… — 1 John 4:1

During this year’s hurricane season, global warming will likely become a topic of discussion at dinner tables across the United States (and likely in other countries as well).

Al Gore recently released his documentary on climate change. “An Incovenient Truth” asserts that global warming is indeed a real occurance, and that it is being caused by CO2 being pumped into the atmosphere by factories, vehicles, etc. Gore also asserts that the majority of the “scientific community” agree that global warming is a human caused phenomenon. Tom Harris, writing for the Canada Free Press says that climatologists are beginning to get fed up with these assertions.

Harris argues that the so-called “majority” of scientists who are cited in reports like those in Gore’s film are not climatologists. They are very qualified in reporting the effects of climate change, but are not qualified to report on the causes of climate change. Reports that computer simulations predict massive climage change are also misleading. These simulations are not really predictions, they are scenarios. According to Dr. Tim Ball, climatology professor at the University of Winnipeg, not only are these models only scenarios but “these models have been consistently wrong in all their scenarios.” Ball claims that it is irresponsible that the researchers behind these simulations have allowed the public to think that their scenarios are predictions.

Before I point you to the rest of the article, there’s a quote from a professor of climatology that I loved: “Gore’s circumstantial arguments are so weak that they are pathetic. It is simply incredible that they, and his film, are commanding public attention.” That comes from Prof. Bob Carter.

Now, while I don’t endorse massive pollution of the environment on principle, I also don’t condone finger pointing at empty space (there is a big star that tends to have quite an impact…some people call it the Sun). That said, this is a great review and commentary on global warming that also cites several experts on climate change.

Jay Richards, Director of Media and a research fellow at Acton, is quoted in the cover article in the new issue of World Magazine. The article, “Greener Than Thou” explores the Evangelical Climate Initiative (ECI) and questions the clarity of its vision and the accuracy of its claims regarding global warming and human-induced climate change. The ECI is the latest environmental policy initiative from evangelical leaders, signed by 86 people including Rick Warren (author of the Purpose Driven Life) and Jack Hayford (president of the Four Square Church).
