June 2017 ENSO update: pancake breakfast 

A change is afoot! After months of suggesting an elevated chance for El Niño to develop, the CPC/IRI forecast has flattened out, and neutral conditions are expected (50-55% chance) to continue through the fall.

A recipe for neutral

In fact, the Nino3.4 region (a key ENSO monitoring area in the tropical central Pacific) is hovering around 0.5°C warmer than the long-term average. Yep, that’s the threshold for El Niño, but surely you remember that ENSO is a seasonal phenomenon, meaning those warmer sea surface temperatures need to stick around for several months—long enough to provoke an atmospheric response

Monthly sea surface temperature Nio 3.4 index

Despite the warmer sea surface temperatures, the atmosphere is not behaving like El Niño. During May, the indicators that we track looked very average, including both the upper-level and near-surface winds over the equatorial Pacific and the amount of rain and cloudiness in the central Pacific and Indonesia. The indexes that measure the difference in the atmospheric pressure between the central Pacific and the far western Pacific, the Southern Oscillation Index and the Equatorial Southern Oscillation Index, were both close to zero in May, indicating, again: neutral conditions.

Most of the recent forecast models predict that the Niño3.4 region will move closer to average temperatures over the next few months. The average of all the dynamical model forecasts in the North American Multi-Model Ensemble flattens out at slightly above the long-term mean for the rest of this year. Averaging all model forecasts together usually produces the best forecast, because it reduces the noise and highlights the signal. Stay tuned—next month, I’m writing a post all about computer climate models. (Try to contain your excitement!)

Combine these neutral atmospheric conditions, cooling forecasts, and the lack of any substantial warmth under the surface of the Pacific, and you get the current forecast of an approximately 50-55% chance of continuing neutral conditions through the fall.

Quote of the Week...

Per Espen Stoknes, a Norwegian psychologist, has examined why people continue to feel disconnected from climate warnings, despite the strength of the science. He says, “People think this is far off – it is not here and now, it’s also up there in the Arctic or Antarctica, it affects other people, not me, I’ll be old before this really happens, other people are responsible, not me. We distance ourselves from it in so many ways that the pure facts are not sufficient to generate a sustained sense of risk”.

SkS Spotlights...

The Renewable Energy Policy Network for the 21st Century (REN21) is the global renewable energy policy multi-stakeholder network that connects a wide range of key actors. REN21’s goal is to facilitate knowledge exchange, policy development and joint action towards a rapid global transition to renewable energy.

REN21 brings together governments, nongovernmental organisations, research and academic institutions, international organisations and industry to learn from one another and build on successes that advance renewable energy. To assist policy decision making, REN21 provides high quality information, catalyses discussion and debate and supports the development of thematic networks.

REN21 is an international non-profit association and is based at the United Nations Environment Programme (UNEP) in Paris, France. REN21’s network structure is made up of the following agents:

– the General Assembly

– the Steering Committee

– the Bureau

– the Secretariat

Darth Trump’s Climate Alliance Exit #Episode I “Hope”

On a planet very near, very near indeed….

It is a period of climate change. The Resistance rushes to bring about a clean energy revolution, but Darth Trump ended a newly formed alliance to address the growing climate crisis.

The Jedi meanwhile try to gather as much climate data as possible, to help better predict future outcomes, and to inform the public. At the same time heat trapping gases are still released into the atmosphere, further contributing to warming the planet.

Renewables 2017 Global Status Report

The 2017 Edition of the REN21 Renewables Global Status Report reveals a global energy transition well underway, with record new additions of installed renewable energy capacity, rapidly falling costs, and the decoupling of economic growth and energy-related carbon dioxide (CO2) emissions.  This year’s report continues REN21’s long-standing tradition of providing the most up-to-date data and informative infographics to detail renewable energy’s contribution to the energy transition.

Climate Feedback Reviews...

Climate Feedback asked its network of scientists to review Global Warming’ Is a Myth, Say 58 Scientific Papers in 2017 by James Delingpole, Breitbart, June 6, 2017

Five scientists analyzed the article and estimated its overall scientific credibility to be ‘very low’.

A majority of reviewers tagged the article as: DerogatoryFlawed reasoningInaccurate, and Misleading

Comments 1 to 5:

  1. Is today's Poster of the Week a joke, or another "fake news" or what?

    Acording to my understanding of current AGW crisis, it's the big oil companies who "contrived" (i.e. brought about) the crisis, and climate scientists have exposed the big oil actions are responsible for it, and not a vice versa.

    The definition of the word contrive (to bring about, to plot) indicates my understanding of the Poster's meaning is correct. Or maybe someone can point ne to see a different nuance here, rather than fake news I'm currently seeing. In any case, the poster is very dubious, if one can understand it like I've at my fisrt glance.

  2. Chriskoz, the poster is satire, and sarcasm, so not to be taken literally.

    But satire is risky. Satire works better in an article, when its possible to insert a couple of little things that are so obviousy insane, it becomes obvious it's satire.

  3. Is the policy against Political comments always the case or is there an exception when politcal discussion is invited like in the Toon of the Week? I assume there are no exceptions?

    [JH] The comment threads for both the Weekly Digest and the Weekly News Roundup are akin to "open threads." Political comments are permitted as long they comport with all of the other parts of the SkS Comments Policy.

    [RH] You have enough to discuss already. Please don't start another topic.

  4. Too @3 , to the best of my knowledge, "Political" comments are strongly discouraged — where "politics" is taken to be in the sense of Partisan Politics (a situation where, as you will doubtless have noticed on the internet, many Americans fall into a brainless and intense left/right tribal battle).  There are abundant websites where such emotional venting is permitted, for those who wish to indulge in that exercise.

    Here at SkS, the website exists for discussion of the science of Global Warming.  AGW is affecting the present physical world, and so affects (in a major way) present and future human society — and so must necessarily involve a political aspect of how to best manage & counteract the AGW problem.   But that means politics in its purest form e.g. the political actions/decisions that should be taken by "Statesmen" who wish to best allocate society's resources to tackle the problem.   This is essentially partisan-free politics.

    While at first glance, the Toon of the Week may resemble something typically found on a partisan newspaper : nevertheless if you look more closely at the situation, you will see that the cartoon disparages three individuals and their anti-science stance (which they take to the detriment of all humanity).   Whether these 3 are partisan-red or partisan-blue, is a matter which is quite immaterial here.

  5. Calm down. Just trying to understand the mores here. I appreciate the eduction on personal versus political mockery. That's a very fine line that is being threaded.
