2015 SkS Weekly Digest #10

Posted on 8 March 2015 by John Hartz

SkS Highlights

Attracting the highest number of comments of the articles posted during the past week were:

El Niño Watch

The long-awaited El Niño has arrived. After keeping a close eye on evolving conditions in the Pacific, scientists yesterday announced the official onset of El Niño, a phenomenon affecting weather worldwide. But the nascent event is likely to have little global impact, scientists say.

The US National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Centre upgraded its assessment from 'El Niño Watch' to 'El Niño Advisory', meaning an event is now occurring.

Scientists have classified the current event as a "borderline, weak El Niño" with a 50 to 60 per cent chance of persisting through Spring. Its weak strength and late timing mean "widespread or significant global impacts" are unlikely, yesterday's report says.

Quote of the Week

Vice President Joe Biden took a strong stance against climate change deniers in an interview with VICE founder Shane Smith.

The interview is part of VICE's documentary series, which airs on HBO and is premiering its third season on Friday. The first episode, titled "Our Rising Oceans," will focus on sea level rise.

"It gets to the point where you can't look anyone in the eye seriously and say, well, it's nothing having to do with manmade," he said.

Reacting to members of Congress who deny climate change is real, Biden said, "It's almost like denying gravity now... the willing suspension of disbelief can only be sustained for so long."

SkS in the News

Lindzen Illusion #2: Lindzen vs. Hansen - the Sleek Veneer of the 1980s  is cited and linked to in the Climate Nexus article, Lindzen Cites Debunked Science to Defend Denier-for-Hire Soon in 'Wall Street Journal' posted on The Huffington Post.

In his Energy & Environment blog post (Washington Post), The GOP’s climate change skepticism, in one groan-worthy video, Puneet Kollipara references and links the SkS Global Warming & Climate Change Myths webpage. 

Tracy D’Augustino, Michigan State University Extension quotes from, and links to, the The Debunking Handbook in her article, Combating science misconceptions: Help take the fiction out of science.

  1. Thanks for the El Nino updates.

    Romm just posted something on likely increases in rates of warming:

  2. Anyone:

    Where is the best information on the Gulf Stream?  I'd like it for a class this Friday in Virginia.  Current flow rate (in Sverdrups), historical flow rates and trends, ancillary effects, theories, peer reviewed publications, effects of El Nino or La Nina events, other thermohaline circulation factors, of note, affecting the Gulf Stream, etc

    Thank You

  3. wili,

    Related to Romm's post and the El Ninoish condition that has developed and may continue through the spring, the current Arctic sea ice extents here appear to be starting to decline early. However, as with any near term climate matter 'wait and see'. A few other years have had similar early dips followed by regrowth of sea ice extent.

  4. swampfoxh, no idea if it is the "best" source, but Google found this.

  5. @ OPOF

    The current "interesting" state of sea ice extent is eliciting more than a few comments on the Arctic Sea Ice Blog.

    Your "wait & see" advice is well made, as, by way of a cautionary example, between Day 68 and Day 80 last year, sea ice area (as measured by UIUC on Cryosphere Today) went up by 600k sq kms.

    The corresponding numbers for Day 68 of 2015 were posted a few hours ago on CT.

    cheers    btf

  6. Folks living near Santa Cruz, California:  There is a Climate & Policy Conference this Friday night and Saturday day.  Richard Alley will be keynote speaker Friday night.
