WGIII is out - Mitigation options and societal impacts

Sou | 4:05 AM Feel free to comment!

The IPCC AR5 WGIII Summary for Policy Makers is now available for download. Without making a recommendation for any particular option, it assesses "the scientific, technological, environmental, economic and social aspects of mitigation of climate change".  It also assesses societal implications of different mitigation policies.
For this assessment, about 900 mitigation scenarios have been collected in a database based on published integrated models.

That's a lot of mitigation scenarios to work through! I'm still reading the report as I write this. It looks as if the main report will be chock full of facts and figures as well as emphasising what will probably seem obvious to most readers.

One item that fits in the "facts and figures" category is this one, about how if we don't do something, we're stuffed:
Without additional efforts to reduce GHG emissions beyond those in place today, emissions growth is expected to persist driven by growth in global population and economic activities. Baseline scenarios, those without additional mitigation, result in global mean surface temperature increases in 2100 from 3.7 to 4.8°C compared to pre‐industrial levels 10 (median values; the range is 2.5°C to 7.8°C when including climate uncertainty, see Table SPM.1)

Yep, the report comes right out and says we could be heading for a temperature rise of 7.8°C.

We've not done enough to stay safe.  We've not promised to do enough to stay below 2°C of warming. But we can get there if we put our collective mind to it.
Estimated global GHG emissions levels in 2020 based on the CancĂșn Pledges are not consistent with cost‐effective long‐term mitigation trajectories that are at least as likely as not to limit temperature change to 2°C relative to pre‐industrial levels (2100 concentrations of about 450 and about 500 ppm CO2eq), but they do not preclude the option to meet that goal (high confidence). Meeting this goal would require further substantial reductions beyond 2020. The CancĂșn Pledges are broadly consistent with cost‐effective scenarios that are likely to keep temperature change below 3°C relative to preindustrial levels. [6.4, 13.13, Figures TS.11, TS.13]

The more we delay the more dangerous and costly it becomes and the fewer choices we'll have.
Delaying mitigation efforts beyond those in place today through 2030 is estimated to substantially increase the difficulty of the transition to low longer‐term emissions levels and narrow the range of options consistent with maintaining temperature change below 2°C relative to pre‐industrial levels

The report includes some pie-in-the-sky scenarios for comparison, such as everywhere on earth starting to mitigate immediately and there is a global price on carbon. It's not all bad news. If we act properly, there will be lots of associated benefits such as clean air (which some parts of the world haven't seen in a while).

The SPM touches on different sectors: transport, buildings, and industry as well as agriculture, forestry and other land use (which has its own acronym AFOLU). It also discusses what actions have been taken around the world to mitigate, in a broader policy context. The final (short) section covers international cooperation.

The main report should also be out shortly.  Meanwhile, you can read the Summary for Policy Makers.


By the way, the only mention of this at WUWT so far is a dig at ClimateProgress (archived here), although for some reason Anthony Watts neglected to mention that the ClimateProgress article was about WGIII.

Anthony probably didn't realise what Joe Romm's article was about, even though it's mentioned in the snapshot he took.  He was too busy trying to make a "funny" out of Joe Romm writing:
You read that right, the annual growth loss to preserve a livable climate is 0.06% — and that’s “relative to annualized consumption growth in the baseline that is between 1.6% and 3% per year.” So we’re talking annual growth of, say 2.24% rather than 2.30% to save billions and billions of people from needless suffering for decades if not centuries. As always, every word of the report was signed off on by every major government in the world.

How deluded is Anthony Watts? Let us count the ways...

Sou | 5:07 AM Go to the first of 9 comments. Add a comment

Anthony Watts has an article up (archived here, updated here) about how people tend to mostly only read articles they agree with.  I'm not surprised if that is a finding.  What I am surprised about is this, from Anthony:
On the plus side, love it or hate it, WUWT is read almost equally by both sides of the climate debate
If it is, they aren't saying.  Remember this poll that Anthony took last year when he was canvassing responses to the Lewandowsky survey?  If that's any guide and I don't see why it wouldn't be, it shows that almost all his readers (more than 97%!!) are fake sceptics.



You only have to read the comments on WUWT articles to know that by far the majority are from people in various shades of denial - from the 8% Dismissives through to utter nutter conspiracy theorists, with rare comments from people who know what they are talking about.  (Anthony limits comments from science types to about two or maybe three on his blog at a time - more than that he censors them or bans people outright.  He can't have facts clearing the muddy waters of denial.)

(Update: so far not a single comment only one comment from anyone who remotely accepts science (Steven Mosher who sort of accepts it a little bit, and posted an utterly irrelevant link about something else), out of 31 responses.  So much for Anthony's claim of being read by "both sides almost equally"!)

Anthony also thinks that arguably the most widely read climate website, Climate Progress, has fewer comments these days because it doesn't post articles from fake sceptics.  Well I beg to differ.  The main reason Climate Progress has fewer comments than it used to have is because it only accepts comments from people having one of the following accounts: facebook, yahoo, AOL or hotmail, which cuts out a lot of people who might otherwise have commented.  Another reason is probably because it's posting more articles each day.

As for stats - ThinkProgress has 287,154 followers and Climate Progress has 59,217 followers - and those are just the Twitter followers.  I'd expect it has multiples of that in readership if you include people who haven't a Twitter account and/or don't follow them on Twitter.  Anthony has 8,510 Twitter followers - nothing to sneeze at but fewer than Michael Mann and an order of magnitude less than Joe Romm's Climate Progress. WUWT might be popular and visited by a lot of people, but ThinkProgress has a considerably larger readership than Anthony Watts' anti-science blog.

I've also got to say that I've yet to see Anthony Watts take any notice of all the science he says he reads.  Heck, from where I sit he doesn't even read half the articles he posts on his own blog.

Update

Ironically, in the HW comments two people who I take to be WUWT regulars reckon there must be many many more "alarmists" than fake sceptics who read but don't comment at WUWT and are arguing that many many more "alarmists" than fake sceptics would have read but not completed Anthony's poll above.  Like 60 times more! Yet Anthony's poll above was to "prove" that it's deniers who didn't take a survey.  And deniers usually complain they are drowned out by "alarmists".

Fake skeptics are not known for consistency or logic or arithmetic or scale or relativities.


From the WUWT comments


Well, there are only a few comments so far (archived here, updated here).  There is nothing of much interest yet. No-one has confessed to habitually visiting SkepticalScience.com :)  I wonder what more of his readers will say. Anthony gave me an indirect plug in his article.  Will I get a rash of visits from WUWT readers who are hoping to broaden their thinking?  (Fat chance!)

Ed Mr. Jones says:

Echo Chambers are where critical thinking goes to die.

DayHay says:

I am part of a consensus, leave me alone.

Tim Walker says:
December 6, 2013 at 9:52 am
Thanks for this introspective post.

This one epitomises WUWT.  Don't leave the safety of deniersville, deride anyone who wants to discuss actual science at WUWT and then complain that "they" won't engage with you. Oh, and write "algore"!   _Jim says:
December 6, 2013 at 10:29 am
Doug Danhoff says December 6, 2013 at 10:12 am I agree in principle, and am discouraged that neither side wishes debate.
Huh?
‘They’ won’t come off their ‘reservations’ or out of their cloistered hallowed ivory towers!!!
What are we to do, stand there with megaphones shouting across the moat?
When was the last time Algore debated anybody?
When we do get ‘one’ here (purported; most come here to troll), they seem to have the mental faculties of a 10 yr old (Sisi?) … I even try to engage the few socialists we have show up in an even-handed non-derogatory manner, JUST to get one under a microscope to see what makes them tick, but, they slink away, choosing not to engage even on a polite level …

Ignorance & callous indifference from Anthony Watts for the victims of Typhoon Haiyan, just to protest global warming!

Sou | 5:52 PM Go to the first of 11 comments. Add a comment
Addendum: See below for my reaction to Bob Tisdale having a shot at me.


The people living in the Philippines and Vietnam are in our thoughts this weekend, with the devastation being wrought by a mammoth typhoon.  This article is about how some science rejectors reacted to the news.

Anthony Watts wrote an article about Super Typhoon Haiyan (Yolanda). True to form, he peppered it with protests about global warming, writing this as his opening line (archived here):
Prepare yourselves for the second coming of Katrina, because you can bet that this storm will be hyped as an indicator of “global warming”.

Anthony liked that line so much that he adapted it in the body of his article.  Anthony didn't mention the people in the path of the typhoon, but he did manage to get in mentions of two of deniers' pet targets: Al Gore and Bill McKibben, writing:
With winds like that, expect to see complete devastation as it makes landfall. That of course will be hyped into an AGW caused storm, just like Katrina. Al Gore and Bill McKibben are already testing lies language on Twitter. Bear in mind that we have a very short historical record of Typhoon strength, and any claims that this is the strongest storm ever need to be qualified with that fact. Nobody has any credible record of typhoon strength back more than a few decades.

I'm not going to write at length about the devastation the storm is causing.  The news is still coming in, with recent reports that more than 100 people perished in the typhoon in just one of the areas hit, Tacloban.

What I'm writing this article for is to point out a bit of idiocy by Anthony Watts and Bob Tisdale.

Anthony wrote that the NOAA was wrong.  Actually he said that Heidi Cullen was wrong.  But Heidi was linking to an NOAA article.

Anthony Watts wrote (archived here):
UPDATE4: Dr. Heidi Cullen of Climate Central wins the “First Haiyan BS award” with this missive. 


Super Typhoon was fueled by lots of heat energy from throughout the water column


Anthony says that both Heidi Cullen and NOAA were writing bullshit.  Here is the NOAA article Dr Cullen linked to in her retweet:
Nov 07, 2013
Warm Water Fuels Haiyan Intensification
The intensification of Super Typhoon Haiyan is being fueled by "ideal" environmental conditions - namely low wind shear and warm ocean temperatures. Maximum sustained winds are currently at 195 mph, well above the Category 5 classification used for Atlantic and East Pacific hurricanes. Plotted here is the average Tropical Cyclone Heat Potential product for October 28 - November 3, 2013, taken directly from NOAA View. This dataset, developed by NOAA/AOML, shows the total amount of heat energy available for the storm to absorb, not just on the surface, but integrated through the water column. Deeper, warmer pools of water are colored purple, though any region colored from pink to purple has sufficient energy to fuel storm intensification. The dotted line represents the best-track and forecast data as of 16:00 UTC on November 7, 2013.

Here is a low resolution copy of one of the NOAA images with the colour bar indicating energy (click here to see the images at NOAA):

Seas are warm in the tropics - warm enough for tropical cyclones to form and grow


Anthony continues putting foot in mouth, writing:
As Bob Tisdale observes, there’s nothing to support this along the track of Haiyan:
Lots of the typical BS accumulating already about Typhoon Haiyan.  Let’s push some of it aside and present the sea surface temperature anomalies for the early portion of Haiyan’s storm track.
There was nothing unusually warm about the sea surface temperature anomalies for the early portion of Typhoon Haiyan’s storm track last week, the week of Wednesday October 30, 2013.  We’ll have to wait for Monday to see what the values were for this week.

"Nothing unusually warm" - says Bob.  But the seas don't have to be "unusually" warm.  Tropical cyclones need warm water to sustain themselves and grow.  Sea surface temperatures in the tropics are generally warm, and often warm enough or else there'd never have been tropical cyclones.  As stated here on a NASA page about the Super Typhoon (my bold italics):
AIRS infrared data also revealed that the sea surface temperatures are warm in the area of the South China Sea where TD30W is moving. Warm sea surface temperatures over 26.6C/80F are needed to maintain a tropical cyclone's intensity and those in the path of TD30W are warmer than that, enabling the storm to intensify through increased evaporation.

And there's no need for Bob to wait until Monday.  He can come here and look at the chart provided by the Bureau of Meteorology from the link on this page (Daily/Globe/Analysis).  I've animated the global sea surface temperature for the 7 and 8 November 2013.  I colour matched the parts on the charts before inserting the arrows.  The sea surface temperature is shown as warmer than 26.6°C over a large area:

Data Source: Bureau of Meteorology Australia

Now the sea surface temperature just has to be warm enough to fuel a tropical cyclone.  Contrary to what Bob Tisdale and Anthony Watts implied, the sea surface does not have to be anomalously warm to fuel a tropical cyclone.  It just has to be above 26.6°C to sustain a tropical cyclone, according to NASA.  Here is the anomaly chart for the 8 November from the link on this page (Daily/Globe/Anomaly).  It shows that most of the area didn't differ from the baseline by more than +/- 1°C, although some areas were 1 to 2°C above the baseline.

Source: Bureau of Meteorology Australia

Now we can understand why Perennially Puzzled Bob Tisdale keeps getting things wrong, even though we can't excuse it.  Bob's not had any formal training in meteorology or climate science and is, by inclination, a climate science denier.  He spends his days trying to figure out how to reject science - ironically having to start with real science from real scientists so that he can distort it and pretend the facts aren't the facts.


Addendum

Perennially Puzzled Bob Tisdale thinks I don't know what I am talking about, writing hopefully "Why Few Find Sou at Hot Whopper to be Credible"  (archived here).  He got distracted by the arrows which I put in to match the map colours to the scale at the bottom (the arrows were not to show where the typhoon was located), so he missed the point I was making.  Surprised?  Not really.

The point I was making was that Bob's comment which Anthony reposted (as quoted above) that "There was nothing unusually warm"  is irrelevant.  As long as the seas are warmer than 26.6C then if there's a tropical cyclone or typhoon it's warm enough to sustain it.

If Bob has a gripe he should take it up with Anthony Watts.  It's got nothing to do with me.  However looking at the post that Anthony Watts copied and pasted (archived here), I have to say that it would be reasonable to assume that Bob's comment about sea surface temperatures were intended to relate to the super typhoon and Anthony and I interpreted it as Bob intended.   Which just goes to prove my point made earlier - Anthony Watts should know better.

Bob expands on and explains in his later post (archived here) that all he was trying to show was that it wasn't global warming that caused the hurricane.  That may be what he was trying to say, but it's not what he wrote at the time (archived here).  I'll leave it to scientists to consider attribution, though I very much doubt it's possible to determine what impact global warming had on a single typhoon.  (Global warming affects all weather but that's not to say that huge typhoons could not happen in a cooler world.)

Oh, and Bob's wrong when he writes: "And one of the persons on this planet she dislikes most is me."  Bob has tickets on himself doesn't he.  I neither like nor dislike Bob Tisdale.  I've never met the man.  I think what he writes is mostly nonsense and I laugh at his sad attempts to show that global warming is caused by magical leaping ENSOs.  But he could be as sweet as a cuddly teddy bear as a person.  I neither know nor care.

Sou 10 Nov 7:53 pm AEDST



However, Anthony Watts studied meteorology for several years (he didn't graduate) and he spent several more years announcing the weather on television.  So what's his excuse?  Did he waste his time all those years and not learn a thing?  Or is it that he doesn't care about facts.  Is it just a matter of "anything goes" as long as it supports his rejection of climate science.


The big question for Bob Tisdale and Anthony Watts: Is it magic or warm oceans?


How do Bob Tisdale and Anthony Watts explain how this super typhoon got started and how did it grow so huge?  They both claim that the sea surface temperatures weren't anomalously warm, which is a straw man because nobody claimed that they were.  Bob and Anthony were trying to argue that NOAA was wrong and there wasn't a lot of energy in the ocean fuelling the storm.  So are they dropping back to the "it's magic" meme so favoured by science deniers?


Will tropical cyclones become more frequent in a warming world?


Super Typhoon Haiyan or Yolanda (depending where you live) was one of the biggest if not the fiercest in the measured record when it made landfall. The science isn't in on whether tropical cyclones will become more frequent.  As I've commented elsewhere, the IPCC latest report, AR5 WG1 it indicates tropical cyclones are projected to stay the same or decrease, but the ones that emerge will be fiercer and wetter.  But there is low confidence (still considerable uncertainty and conflicting analysis, particularly whether all strengths of cyclones will increase in frequency or whether it will only be the biggest ones.)


From the WUWT comments


There were quite a few WUWT readers who didn't slavishly follow Anthony Watts' lead, and who recognised the devastion.  However others mocked the plight of those in areas devastated by the typhoon. For example, philjourdan doesn't appreciate how unusual was Sandy or Super Typhoon Haiyan.  He says:
November 8, 2013 at 12:55 pm
One thing I think most of us have missed (and if I missed a comment addressing this, my apologies).
Haiyan is a pussy cat of a storm! How do we know? Climate Alarmists tell us this. They claim Sandy was a superstorm because of the billions in damages done! Haiyan’s damage total is going to come no where near that. So it cannot be a bad storm.

While there were some who decided that "warmists" would hijack the issue, not seeing that it was Anthony Watts himself who used the tragedy to push his denialist barrow.   For example, Andy Wilkins says:
November 7, 2013 at 2:18 pm
It’ll be horrific for anyone in the direct path, and what annoys me most is that people such as the odious Joe Romm will use these peoples’ suffering to advance his warmist agenda.
I checked climateprogress and found an article, not by Joe Romm but by Katie Valentine.  She did reference climate change at the end of her article about the typhoon, but with a much lighter touch than Anthony Watts' protest and in context - writing this:
The Philippines are no stranger to typhoons — around 20 hit the island nation each year. Just last December, Super Typhoon Bopha slammed into the country with 175 mph winds, causing widespread destruction and killing nearly 650 people.
The Philippines has appealed for international help on the role of climate change in such weather events before. During last year’s international climate talks in Doha, which were underway when Super Typhoon Bopha made landfall, the lead negotiator for the Philippines broke down as he asked participating countries to do something about climate change, saying the country had “never had a typhoon like Bopha.”
“I appeal to all, please, no more delays, no more excuses,” he said. “Please, let Doha be remembered as the place where we found the political will to turn things around. Please, let 2012 be remembered as the year the world found the courage to find the will to take responsibility for the future we want. I ask of all of us here, if not us, then who? If not now, then when? If not here, then where?”
This year’s international climate talks will begin next week in Warsaw.


TomRude probably dismisses any expert in meteorology and says:
November 8, 2013 at 12:28 pm
It’s been a long time since Jeff Masters could be taken seriously…

jonny old boy might reject climate science but he knows a Super Typhoon when he reads about it and says:
November 8, 2013 at 11:04 am
this storm will make history if its track prediction is accurate…. it is shaping up to be Vietnams biggest natural disaster in its modern history. This is nothing proven to AGW/climate blah blah blah but this IS unusual and extremely violent.

Old England couldn't give tuppence for people living far from the motherland or for climate science, and mockingly says:
November 7, 2013 at 1:51 pm
Typhoons of this strength are unprecedented before tens of thousands of wind turbines were been erected – ergo they must be related to and with 95% certainty caused by the number of wind turbines – or have I misunderstood how the reasoning behind most of warmist ‘climate science’ works ?

If you're interested you can read more comments archived here.  They are a mixed bag of sympathy, mockery and, of course, the usual rejection of science.

Anthony Watts claims he's won the Battle of the Brains ...ha ha ha

Sou | 8:16 PM Feel free to comment!


Anthony thinks he's clever, cleverer even than Dr Joe Romm


This quote from Anthony Watts (of WUWT) is funny, though once again it's not tagged as "humour".  Anthony decides he is cleverer than 'alarmists', in fact he even thinks he's smarter than Joe Romm and writes:
From the University of Alberta, this news release is making the rounds, but what many of the alarmists don’t get (Joe Romm for example) is that these plants had to have a warm environment to grow in first, then they were covered by ice, emerging again after the LIA ended. Many reports are only looking at the current emergence in a warmer period as if it is unique. – Anthony
Anthony, I believe you'll find, should you ask him, that Dr Romm knows that the bryophyte was not frozen in ice before it was frozen.  I wouldn't mind betting that there might even be one or two of Anthony's Dismissives who would twig to that.

Clever little Anthony is correct when he writes that the bryophytes emerged after the end of the Little Ice Age ended.  They emerged about 160 years after it ended.

It took more than the ending of the little ice age for these mosses to emerge.  It took human activity to heat up the world and cause a widespread and sharply accelerating ice retreat across the Canadian Arctic Archipelago according to the abstract:
Across the Canadian Arctic Archipelago, widespread ice retreat during the 20th century has sharply accelerated since 2004. In Sverdrup Pass, central Ellesmere Island, rapid glacier retreat is exposing intact plant communities whose radiocarbon dates demonstrate entombment during the Little Ice Age (1550–1850 AD)....


What makes this warming unique


As for this warmer period being unique - does anyone think Anthony would be willing to admit its unique features?  Here are some unique features of this warmer period:

  • It's the first time ever since Homo sapiens evolved that carbon dioxide has been this high;
  • It's the first time in the history of earth in which there has been such a rapid period of warming as a result of human activity;
  • This past hundred years marks the first period ever in the history of Earth that any species has had the power to choose whether to end the world as we know it or whether to limit the damage being wreaked upon life on earth.
  • It's probably the first major mass extinction event since the Cretaceous–Paleogene (K–Pg) extinction event, which took place about 66 million years ago.
  • It would be the first time in the history of earth that a sentient species knowingly and willingly charged full pelt towards its own destruction, if Anthony Watts had his way.


Who's won the Battle of the Brains?


Hands up everyone who thinks Anthony Watts has it all over his scientific dog, Kenji and Dr Joe Romm when it comes to intellect.

Who has the best brain?





Now to the unfrozen bryophytes.  Here again is a link to the abstract in PNAS1.  Below is a repost from The Conversation.

Frozen plants from the Little Ice Age regenerate spontaneously

By Akshat Rathi, The Conversation

Retreating glaciers are proving to be good news for plant scientists. Underneath one such glacier on Ellesmere Island in Canada, researchers have found plants they believe have regrown after being entombed in the glacier for more than 400 years, since a cold period called the Little Ice Age.

These plants are called bryophyte, a group that includes mosses. They are non-vascular, which means they do not have tissue that distributes resources throughout the plant and they do not reproduce through flowers and seeds. They use spores instead. But they also possess the ability to regrow from tiny fragments of themselves through a process called clonal growth. “This ability makes bryophytes pretty tough,” Andrew Fleming, a plant scientist who was not involved in the study, said.

The discovery reported in the journal Proceedings of the National Academy of Sciences was made by a team led by Catherine La Farge, an expert on bryophytes at the University of Alberta. Because the bryophytes found were not much different from similar variety found in the wild today, La Farge used radio carbon dating to confirm the age of their find.

The plants were trapped during a period known as the Little Ice Age, between the 16th and 19th centuries, when glaciers were growing in size. Arctic glaciers have recently been retreating and, since 2004, the rate of ice melt has increased dramatically. La Farge is hopeful that, in addition to these plants, the melting glaciers will release other interesting flora and fauna of that time.

When these bryophytes were found they were blackened, but sported a hint of green. 
See to the right of the rock in the middle. Catherine La Farge

This discovery does not displace the record of the oldest frozen plant to be regenerated. That belongs to a 32,000 year old specimen of Silene stenophylla, which was regrown by using tissue extracted from its frozen seeds.

These bryophytes are also not the hardiest plants we know. That title belongs to what are commonly known as resurrection plants, which are able to survive extreme dehydration. Some of these are commonly found in deserts, such as Selaginella lepidophylla found in Chihuahuan Desert on the border of Mexico and the US.

Liars in the MSM are called to account

MobyT | 2:10 AM Feel free to comment!
It's good to see more and more people speaking out against lies, odious rants, rampant misogyny and disinformation on the internet, particularly when it comes from 'personalities' and mainstream media. 

Climate Progress has a report by Graham Readfearn about the Australian Press Council findings in relation to lies written by Andrew Bolt and offensive articles penned by James Delingpole (speaking of odious).

More and more people are starting to take action against disinformation of the type The Australian revels in.  Tim Lambert from Deltoid continues to act as a watchdog, reporting its frequent untruths about climate science.  In his latest piece, he writes about a particularly disgusting and false headline in The Australian.

I wonder if it's because as global warming gets worse, science deniers are decreasing in numbers and it's left to the more extreme ratbags to write stuff.
