Rosenthal et al 2013
Posted on Nov 2, 2013 by Steve McIntyre
There has been considerable recent attention to Rosenthal et al 2013: WUWT here, Judy Curry here, Andy Revkin here.
The article itself presents a Holocene temperature reconstruction that is very much at odds both with Marcott et al 2013 and Mann et al 2008. And, only a few weeks after IPCC expressed great confidence in the non-worldwideness of the Medieval Warm Period, Rosenthal et al 2013 argued that the Little Ice Age, Medieval Warm Period and Holocene Optimum were all global events.
Although (or perhaps because) the article apparently contradicts heroes of the revolution, Rosenthal et al 2013 included a single sentence of genuflection to CAGW:
The modern rate of Pacific OHC change is, however, the highest in the past 10,000 years (Fig. 4 and table S3).
In the Columbia and Rutgers press releases accompanying the article, this claim was ratcheted up into the much more grandiose assertion that modern warming is “15 times faster” than in previous warming cycles over the past 10,000 years (though the term “15 times faster” is not actually made in the peer reviewed article):
In a reconstruction of Pacific Ocean temperatures in the last 10,000 years, researchers have found that its middle depths have warmed 15 times faster in the last 60 years than they did during apparent natural warming cycles in the previous 10,000.
Rather than quoting the article itself, Michael Mann, an academic activist at Penn State University, repeated the claim from the press release in an article at Huffington Post entitled “Pacific Ocean Warming at Fastest Rate in 10,000 Years”. – Click here to read the full article
Historical Temperature Trends In Antarctica
Posted on November 2, 2013 by Paul Homewood
SPPI have just published “Historical Temperature Trends In Antarctica”, which gives an overview of recent studies of temperature trends from the ice age to the present day. The paper is 14 pages long, but I will try to sum up the main points here.
The first section summarises the glacial periods, really making the, now well established, point that temperature changes preceded CO2 changes, and did not follow. As I say, this is now well established, so I will move on to the next section.
The paper identifies several studies which provide evidence that Antarctic temperatures were higher than now in both the Roman Warm Period and the Medieval Warm Period. There is also substantial evidence of the Little Ice Age there.

The Revenge of Lewandowsky – our deserts
Posted on November 3, 2013 by Jeff Id
Sorry to have been gone so long. It seems impossible to blog with so many other fun things going on. Still, I read my favorite blogs and occasional climate paper, even if I don’t comment much. Recently Lewandowsky et Mann (birds of a feather?) published yet another pro-government rant claiming to be science related.
It is hardly worth reading but read it I did: The Subterranean War on Science. My willingness to read that is proof that I am literally as dumb as a rock. Don’t make the same mistake!
The article is one of the most disgusting pieces I have yet read from the “Climate Science™” community. It is written as though it actually has supporting references but the article is beyond reprehensible in content. It has literally zero scientific value and wouldn’t make the cut at a blog but somehow a “journal” managed to publish it. I did manage to leave a comment:
I can’t believe the self-righteous tone of these alleged scientists. I also am stunned at the fact that fake work like this continues to be touted as having any foundation in actual science.
Whether you agree with their other work or not, this paper is nothing but government funded pro-government propaganda and they, and their coworkers, should each be ashamed at having their names and institutions associated with it. Completely disgusted.

Solar Activity Makes Big Headlines
Posted on November 3, 2013 by Inform The Pundits!
Last month had the largest monthly change in solar sunspot activity since July 2007.
October was a very busy month for solar storms linked to sunspots. They made global headlines.
Daily sunspot tallies make up the oldest continuous data series in all of science. It officially goes back to January of 1749.
Sunspots are ginormous solar magnetic storms that unleash powerful solar winds and lethal doses of radiation directly affecting Earth. Knowing how many there are is vitally important.
How accurate have sunspots been counted? How well have we recorded the 11-year sunspot cycle over the centuries?
The surprising answer to that question is, not very well!
A look at October’s daily sunspot tallies demonstrates it. – Click here to read the full article
UKIP, energy policy and the shift of public opinion on EU membership
Posted on November 3, 2013 by tallbloke
This is just a brief post regarding the UK’s need to regain its sovereignty, and UK Independence Party’s tactics to achieve that goal. This is vital if the UK is to regain control over its energy policy, and end the madness of the E.U. Tory/Libdem and Labour party obsession with ‘carbon emissions’. – Click here to read the full article
“as disconnected from reality as an abandoned wind farm is from the grid” …

Green fantasies have been at the forefront of government waste spending for the past 6 years, peaking during the ‘Gillard Period’. Time for ‘change’, via Greenie watch:
Let’s get rid of all the useless wind farms
By TERRY MCCRANN, a much-read Australian financial journalist
I STILL have a dream. Of that one day when we start pulling down all the utterly useless, landscape-blighting, bird-killing, people-punishing, so-called wind farms.
We’ll leave a few, some stripped of their turbines, some left with a blade to turn lazily and even more uselessly in the occasional breeze; all, like fragments of the Berlin Wall, as testimony to the time when insanity engulfed our supposed intellectual and policy-making elites. – Click here to read the full article
Shock News : Policy To Increase Wind Farms Across East Australian Grid “A Dangerous Strategy”
Posted on November 4, 2013 by CACA
Academic Study :
WIND FARMS IN EASTERN AUSTRALIA – RECENT LESSONS
“…careful scrutiny of the available wind farm operational data shows that, on the eastern Australian grid, it is not possible for wind energy ever to displace dispatchable, reliable generation supplying the base load demand. In this regard, an examination of the graphs comprising Figure 3 clearly indicates that the proposal by some Australian policymakers to replace major coal-fired power stations with a fleet of wind farms is not technically achievable.
Additionally, the analysis shows that further increased wind penetration, even if spread evenly across the eastern Australian grid, will result in an increasing contribution to grid instability, potentially making wind energy an increasing threat to grid operational security and reliability. To continue a policy strategy to increase wind penetration across the eastern Australian grid, to seek to meet a target of some 20% installed capacity, as has already been achieved in South Australia, (with the presumption that wind may thereby meet 20% of base load requirements), has the potential to be a dangerous strategy. – Click here to read the full article
No thanks but yes please
Posted on November 4, 2013 by Trust, yet verify
This is something I didn’t expect. According to CNN four climate scientists wrote an open letter to use nuclear in order to fight global warming. They state that only nuclear power can make enough clean power to slow climate change. Those who signed the statement: James Hansen, Ken Caldeira, Kerry Emanuel and Tom Wigley. Rather known by those following the climate controversy.
If we assume that CO2 is the problem, then nuclear energy would be the path to go. It is a proven technology, it doesn’t emit much CO2 (only at extraction and with transport) and gives a reliable output. Considering that renewables are still a marginal part in the energy mix, nuclear energy should be the logical choice when one wants to abandon fossil fuels. – Click here to read the full article
The Oceans are Not More Acidic Now Than in the Past 300 Million Years [UPDATED]
Posted on October 6, 2013 by Ruth Dixon
…as the Guardian now agrees.
[Update: 9 Oct 2013 13.01 pm: The headline and first paragraph of the article have now been changed following email correspondence between Fiona Harvey and me. Credit to Fiona and the Guardian for this response. The links now lead to the updated version which can be compared with the screenshot below. Further update: See also http://www.newssniffer.co.uk/articles/690315/diff/0/1 for a side-by-side comparison.]
Fiona Harvey’s article in the Guardian on 3 October 2013 Ocean acidification due to carbon emissions is at highest for 300m years misrepresents the scientific literature. This error has propagated across the Twittersphere.

Pragmatic leverage points to tackle climate change
Posted on November 3, 2013 by Judith Curry
It’s time to move beyond the old debates and endless gridlock, and find pragmatic, new leverage points to tackle climate change. – Jon Foley
Jon Foley has an interesting essay entitled Breaking the Cycle of Climate Inaction. Excerpts:
One reason we’re so stuck is that most of the climate solutions being proposed are beyond the capabilities and vision of national political leadership.
Let’s face it: Politicians in Washington can’t even pass a routine budget bill, and the United Nations can’t pass a resolution condemning Syria for gassing its own civilians.
[W]e need to match our climate solutions to situations where leadership is still effective. We need to find targeted, strategic opportunities to reduce emissions, matching solutions to effective leadership. – Click here to read the full article
