New study: ‘…climate system is only about half as sensitive to increasing CO2 as previously believed’

A giant step in the right direction.

UPDATE: Also see Roy Spencer’s blog post here that discusses this paper.

Watts Up With That?

Warming since 1950s partly caused by El Niño

HUNTSVILLE, Ala. (Nov. 11, 2013) – A natural shift to stronger warm El Niño events in the Pacific Ocean might be responsible for a substantial portion of the global warming recorded during the past 50 years, according to new research at The University of Alabama in Huntsville (UAH).

“Our modeling shows that natural climate cycles explain at least part of the ocean warming we’ve seen since the 1950s,” said Dr. Roy Spencer, a principal research scientist in UAH’s Earth System Science Center and the new study’s lead author. “But we also found that because the globe has had more frequent La Niña cooling events in the past ten or fifteen years, they are canceling out some of the effects of global warming.”

    Bob,
    I would like to send you an essay regarding a hypothesis of major climate change. Could you send me an address to send to?

    Reply: kingdube, I deleted your email address to cut down on the spam you might have gotten.

    Can you link the paper?

    Regards

    Bob

    This work reminds me of the work by DeFreitas et al on ENSO that caused such a kerfuffle as exposed in the Climategate emails. But it is so good to see that others are waking up and describing the influence of the ocean cycles. With kind regards, Robin.
