2014 SkS Weekly Digest #47

Posted on 23 November 2014 by John Hartz

SkS Highlights

President Obama's climate leadership faces the Keystone XL challenge by John Abraham attracted the highest number of comments of the articles posted on SkS during the past week. Coming in a close second was John Cook's Why we need to talk about the scientific consensus on climate change. Both articles were inititally posted on the blog, Climate Consensus - the 97% hosted on The Guardian.

Quote of the Week

According to Francis*, the extreme U.S. winter of last year and now, the extremes at the beginning of this season, fit her theory. "This winter looks a whole lot like last winter, it’s a very amplified jet stream pattern," she says. "We know that when we get these patterns, it tends to be very persistent. And it is definitely the type of pattern that we expect to see more often as the Artic continues to warm so fast."

*Jennifer Francis, Research Professor, Rutgers University

Comments 1 to 2:

  1. The "Tropical Pacific Ocean moves closer to El Niño" link is not working.  It links to a page with the address "" which gives a 404 error.

    Moderator Response:

    [JH] Link fixed. Thanks for bringing this glitch to our attention.

  2. I am looking forward to Alexandre Lacerda's upcoming SkS item “Drought and Deforestation in Brazil”

    The need to be able to reasonably predict things like El Nino/La Nina and resulting regional rainfall is highlighted by the current drought in Sao Paulo.

    Even if El Nino could be more reliably predicted the potential rains in Sao Paulo would appear to be difficult to reliably forecast. The presentation of El Nino impacts summarized by NOAA here indicates that rainier conditions would be expected in southern Brazil but potentially not as far north as Sao Paulo.

    An added challenge of the rapid climate change due to rapidly increased impacts like atmospheric CO2 appears to be that rapid short-term changes of climate patterns make it even more difficult to establish reliable short-term forecast models (models to regionally predict things like generally expected rainfall 3 to 6 months in advance) because what has happened in the past in the short-term is less likely to be what will happen in the future.

    Sao Paulo appears to be at the mercy of whatever will come in the next few months. And a few years ago Tofino on 'reliably rainy' Vancouver Island had its reservoir almost run dry without getting warning several months in advance that it was likely to happen.
