A few others have addressed this issue in previous posts, but I wanted to jump in with my two cents.

Yesterday’s New York Times notes that a group of evangelical leaders have entered the debate over climate change:

Despite opposition from some of their colleagues, 86 evangelical Christian leaders have decided to back a major initiative to fight global warming, saying “millions of people could die in this century because of climate change, most of them our poorest global neighbors.”

Among signers of the statement, which will be released in Washington on Wednesday, are the presidents of 39 evangelical colleges, leaders of aid groups and churches, like the Salvation Army, and pastors of megachurches, including Rick Warren, author of the best seller “The Purpose-Driven Life.”

“For most of us, until recently this has not been treated as a pressing issue or major priority,” the statement said. “Indeed, many of us have required considerable convincing before ing persuaded that climate change is a real problem and that it ought to matter to us as Christians. But now we have seen and heard enough.”

Later in the article, Rev. Ted Haggard – speaking for himself and not in his capacity as president of the National Association of Evangelicals, which is not participating in this effort – states that “there is no doubt about it in my mind that climate change is happening, and there is no doubt about it that it would be wise for us to stop doing the foolish things we’re doing that could potentially be causing this. In my mind there is no downside to being cautious.” Well, no downside except nearly destroying the global economy in an effort to reverse a process that may or may not be caused by man in the first place. (Jay Richards sums up the downside nicely in this post.)

One wonders whether Rev. Haggard and the others behind this declaration have been informed of the recent discovery that plants release vast amounts of greenhouse gasses. Or that one of the most famous pieces of supporting evidence for the global warming hypothesis – the “hockey stick” graph that purports to show a sudden rise in global temperatures at the beginning of the 20th century after centuries of relative stability – has been found to be riddled with serious errors. Or that global warming is not just restricted to Earth, but also seems to be occurring on other planets in the Solar System, which may cause one to think that global warming on Earth might just have something to do with… the Sun.

The group will be taking their message into the media via a television campaign:

The television spot links images of drought, starvation and Hurricane Katrina to global warming. In it, the Rev. Joel Hunter, pastor of a megachurch in Longwood, Fla., says: “As Christians, our faith in Jesus pels us to love our neighbors and to be stewards of God’s creation. The good news is that with God’s help, we can stop global warming, for our kids, our world and for the Lord.”

That would all be well and good if we knew for sure that humans were the cause of global warming. But it’s clear that we don’t know that for sure. (And if warming is indeed caused by the Sun, pletely dependent on God for a solution unless we embark on a Monty Burns style quest to block the Sun’s energy from reaching Earth.) In their editorial on the “hockey stick,” the Wall Street Journal sounded a note of caution that we would all do well to heed:

But the important point is this: The world is being lobbied to place a huge economic bet–as much as $150 billion a year–on the notion that man-made global warming is real. Businesses are gearing up, at considerable cost, to deal with a new regulatory plex carbon-trading schemes are in the making. Shouldn’t everyone look very carefully, and honestly, at the science before we jump off this particular cliff?
