Natural forces affect climate? Who knew?

"Near-surface warming in the Arctic has been almost twice as large as the global average over recent decades -- a phenomenon that is known as the 'Arctic amplification'. The underlying causes of this temperature amplification remain uncertain."

So begins an article in the current edition of Nature -- another apparent repudiation of the "science is settled" mantra.

Associated Press story here.

The study reportedly doesn't contradict global warming consensus or dispute a human influence but indicates what's happening is much more complex, and less understood, than we're generally led to believe.

It reinforces my skepticism about efforts to stop or reverse global warming. If there are powerful natural forces at work -- as obviously there always have been through the planet's earlier warming and cooling episodes -- how much really can be done to make any difference?

I certainly support efforts to conserve energy and reduce pollution. It's logical to conclude that we should stop doing whatever may be harmful. But I remain leery of costly and potentially economically ruinous remedies that ultimately will have little beneficial impact.

It may be that it's more practical to seek ways to adapt to changes in climate than to attempt to change climate.

Stop making sense on this issue, Doug.

Don't you know that's not allowed when we're discussing a cherished political/social/economic agenda item like this?

Now that's applied rationality on settled science.

Excellent post.

Thanks, guys. This may strike some as heresy.

Doug, global warming has become the "third rail" of politics these days; very gutsy of you to use truth and common sense to question the Algore's of the world.
Cyclical climate change was around long before man, and will continue after we're gone.

Doug said:

Not me. But there are plenty of scientists, like hurricane expert Bill Gray, who say this is all a lot more complicated, and fraught with more uncertainty, than Al Gore and others tell us. Gore says global warming will produce more frequent and powerful hurricanes. Gray says not so, hurricanes follow natural cycles.

Stop making sense on this issue, Doug.

Bubba! I have just bought you a ticket to the San Francisco Zoo, since a recent and amazing thing has happen. A baby Polar Bear floated into San Francisco Bay on a very large ice cube, waving a Exxon Flag. You will find the little baby Polar Bear in the old Tiger part of the park at the zoo. I expect you to give a big hug to the little Bear as a welcome effort from you..
Can I depend on you? Or will we have to ship you North on the Ron Paul bimp to prove that Global warming does affect impair Republican minds?

Doug, the principle of "look before you leap" is heresy to any shyster trying to panic people into an unresearched sale. They're trying to make people leap with their scary cant and their insistence that the "science is settled." There's a post on EnvironmentNC that talks about John Tierney's article on how last year's scares didn't materialize: it wasn't the warmest year on record (coldest since 2001), sea ice grew faster than ever, hurricane seasons have been mild, etc.

Doug said:

Thanks for the link, Jon. It's helpful to have that information.

The laugh of the year was when a government grant scientfic Global warming research group made plans to go to the Arctic expecting a easy path to the scene of the Global warming crime and was frozen in much early than their research data claim. Their leader was quoted as saying " We had no idea where all of this ice came from?"

Doug Johnson said:

There was a story yesterday, where the Russian scientist were warning of global cooling.
