DF has posted that the Antarctic Ice extent has increased. It has indeed. However, the volume of land-borne ice in Antarctica is falling:

http://www.theguardian.com/environment/ ... -satellite

Ice on the sea melting or accruing will not affect sea levels as much as ice lost from glaciers and ice sheets on land.

By the way Sass, when was it that we 'conquered nature'. Were we just being hubristic?

It is certainly healthy to be skeptical; it is one of the rights/ requirements of being a citizen in a democracy to be skeptical of what the powers that be are telling you. However, the anti-science bias that is manifest in a good part of the opposition to climate change is not valid in my mind.


What you claim is "anti-science bias" was based on writing by a scientist--and a climatologist. Lennart Bengtsson is not a rube or a "denier." However, when he raised questions, he was attacked.

RJ and I might disagree about climate change and the methods used to address it, but at the end of the day it is just a problem to be solved and not a stand-in for larger issues. Science has ushered in the amazing progress we have seen over the past several hundred years--not religion.


Science that does not question is not science; it is religion.

The persistence of religion, in spite of scientific undercutting of its validity, is a testament that religion continues to provide things largely missing in modern society (meaning, a sense of community, shared values, solace for old age and fear of death, etc). Science will continue its search for truth instead of received truth.


In the case of AGW, this is false. The "received truth" is that Man is responsible for Global Climate Chaos and the only option we have is to drastically cut our use of carbon-based fuels, no matter what or Kevin Costner's Waterworld will be our future.

And it is still the best way to a better society. And while it is understandable why those that are religious would be eager to point out the limitations of science, that anti-science bias driving at least some of the climate change opposition is a cause for concern
.

Meh. I'll not be dragged into your anti-religion rant.

Part of our hubris is believing we know that the Earth is incapable of adapting in ways we don't foresee.

Again, if a scientist, or many of them, can see that their models are not accurate, then isn't there reason to do more research and more thinking, rather than just assume that the science that led to flawed modeling is "settled?"

I think you may find that could work both ways.

Oh, there certainly is a case for more research. That is what the IPCC is about - showing the results of the latest research.

But how inaccurate are these models, really? It's easy to cherry pick the most extreme examples (often the top value of a range of projected outcomes), but how wrong are the standard models?

This is just semantics. My point is that we're not just slaves to our environment, we have the capacity to shape it through technology.

Yes, we do. But there are unintended consequences sometimes. And you seem quick to do down the renewable energy technologies.

For example, much is made of the variability of renewables (in that hydro, wind and solar all rely on a non-constant energy source). However, a study in the US showed that going up to 33% of power from renewables would save money overall - the cost of the variability was outweighed by the savings. http://arstechnica.com/science/2013/09/ ... avings/#p3

It's also easy to point at the eco-nutters and denounce them (and then by extension, apply the broad brush to everyone who agrees with the scientific consensus which is far less extreme). That's like pointing to Fred Phelps and using it to denounce all Christians.

And even then it's not always as simple as you point out:
The green lobby is way too dogmatic in my view. They endlessly harp on about the need to cut emissions and yet at the same time refuse to countenance the two forms of energy we currently have (gas and nuclear) which have proven to be most successful in effecting a cut in carbon.
One of the most high profile environmental disputes is over DRAX power station in Yorkshire. It's not a nuclear station, it's not even a gas power station. It's a relatively new (originally opened in 1974, but only fully completed in 1986) coal power station. The largest in the UK, it is also the largest single source of CO2 emissions in the country. It also uses petcoke (petroleum coke, a byproduct of petroleum cracking and other processes) which emits more CO2 than coal, and also has a high sulphur content.

While on DRAX...

I'm very reluctant to see my bills spiral out of control and see thousands of jobs disappear from my country to more lax regimes so we can be sacrificed on the altar of 'sustainability'.
Much of the coal burned at DRAX comes from overseas. While it sits on the Selby field, a large coal seam, only a handful of UK mines are still open. So we import from Poland, Russia, South Africa, Colombia. Thousands of miles away and not all of them the nicest of regimes.

Of course, DRAX is now using some biomass for burning. Which will save money, reduce the need for imported coal and reduce CO2 emissions. I think it's to be supported in that move, but I can also see that it's not the ultimate solution - it's still burning stuff (which is wood pellets imported from Southern US states).

America is pretty much the only major economy to have cut carbon emissions in recent years and it hasn't done that by moving to renewables, it's done it by the move to gas from highly polluting coal as an interim measure.
Most likely it's been caused by recession. I looked to see longer term trends.
http://en.wikipedia.org/wiki/File:Regional_trends_in_annual_per_capita_carbon_dioxide_emissions_from_fuel_combustion_between_1971_and_2009.png


Seems that OECD (Western) Europe has also reduced per capita emissions over the past 30-40 years. And also sharply at the end of the last decade (again, recession). The most startling cuts have not been in the USA, but in Russia and Ukraine (which dominate the non-OECD Europe) in the early 1990s.

I'm not sure if that really supports your argument tbh. The most startling reductions have come in countries which have seen the steepest drop in living standards.

That's a slightly disingenuous point of course, since in no way could you accuse Russia and Ukraine of following a green agenda. Their falling standard of living hasn't been caused by trying to control carbon emissions. However, it does neatly show the correlation between carbon emissions and economic output.

The second part is absolutely and demonstrably true. Its since the industrial revolution that CO2 and other warming gases have been accumulating in the atmosphere and oceans, and warming the planet.
But we live in the environment. We aren't slaves to it but inhabitants of it.

The question is are we slaves to specific technologies? Tied to them by economic bonds, enforced by those who gain from the relationship. (The coal mining companies, oil companies etc.)
Or can we adapt and use technologies that don't shape our environment negatively but still provide most of the benefits of the technologies who's byproducts have shaped the environment?

This is a different take on a story I posted the other day

In their desperation to find even a tiny shred of peer-reviewed science to challenge the volumes of research from around the world about human-caused climate change, deniers have often held up Willie Soon's work.

Dr. Soon, an astrophysicist at the Harvard-Smithsonian Centre for Astrophysics, is known for studies that purportedly show that the sun, and not CO2 emissions from human activity, is the main factor in climate change, and that climate change in the 20th century wasn't that unusual to begin with. He has also argued that mercury emissions from burning coal are no big deal.

Now, in response to a Greenpeace investigation, Dr. Soon has admitted that U.S. oil and coal companies, including ExxonMobil, the American Petroleum Institute, Koch Industries, and the world's largest coal-burning utility, Southern Company, have contributed more than $1 million over the past decade to his research. According to Greenpeace, every grant Dr. Soon has received since 2002 has been from oil or coal interests. This despite the fact that he once told a U.S. Senate hearing that he had not been hired by, employed by, or received grants from any organization "that had taken advocacy positions with respect to the Kyoto protocol or the UN Framework Convention on Climate Change."

Dr. Soon has also been affiliated with a number of industry front groups, including the coal-funded Greening Earth Society, and Koch-Exxon-Scaife-funded groups including the George C. Marshall Institute, the Science and Public Policy Institute, the Center for Science and Public Policy, the Heartland Institute, and Canada's Fraser Institute.

Correspondence uncovered by Greenpeace also found that Dr. Soon led a plan in 2003 to undermine the Intergovernmental Panel on Climate Change's Fourth Assessment Report years before it was even released in 2007.

It's not news that the fossil fuel industry has funded an ongoing campaign of doubt and misinformation about the effects of its products and about the dangers of climate change -- people and organizations from science historian Naomi Oreskes (author of Merchants of Doubt) to Greenpeace have been exposing these efforts for years. From hiring trolls and front groups to post comments on websites, submit letters to editors, and write opinion columns to sponsoring "scientific" research and holding conferences, it's all been well documented. (The same tactics have also been used by the tobacco industry.)

The latest revelation is a bit of an embarrassment for oil giant Exxon, though. The world's largest oil company had admitted that it funded these efforts but promised in 2008 it would stop giving money to groups that lobbied against the need to find clean energy sources.

It's also an embarrassment for those who, in the face of overwhelming scientific evidence, deny the existence of climate change -- or admit that it's happening but say we can't and shouldn't do anything about it. Of course, they will continue to repeat the same discredited points about "climategate" and medieval warm periods and CO2 as plant food, and they'll continue to take the advice of industry shills like Tom Harris to bombard the media with opinion articles and letters to editors and to post numerous comments under online articles.

Some rightly point out that we should look at the science and not at who is paying for the research. So what about Dr. Soon's science? Well, let's consider one paper that Dr. Soon published with colleague Sallie Baliunas, which attempted to discredit the work of Michael Mann, director of the Earth System Science Center at Pennsylvania State University. Three editors of the publication that ran the study resigned in protest, including incoming editor-in-chief Hans von Storch. He said "the conclusions [were] not supported by the evidence presented in the paper." Greenpeace notes also that 13 of the scientists cited in the paper published rebuttals stating that Dr. Soon and Dr. Baliunas had misinterpreted their work.

After all their digging, deniers have only been able to find a few minor errors in the volumes of peer-reviewed science about climate change, and have had to rely on manufactured scandals and conspiracy theories to bolster their arguments. It only takes a bit of investigating to poke holes in the scant bits of research that have attempted to discredit real climate science. Let's stop wasting our time on deniers. It would be better spent trying to resolve the serious problems we have created.

About the 97% "consensus" thing, apparently it's a bit misleading:

Where did this 97 percent figure come from? This story has become interesting over the last few days. The most prominent form of it comes from Prof. John Cook of the University of Queensland in a paper published last year that purported to have reviewed over 11,000 climate science articles. Does anyone really believe that Cook and his eight co-authors actually read through all 11,000 articles? Actually, the abstract of the paper supports the point I made above that most papers don’t actually deal with what the Climatistas say:

We find that 66.4% of abstracts expressed no position on AGW [Anthropogenic Global Warming], 32.6% endorsed AGW, 0.7% rejected AGW and 0.3% were uncertain about the cause of global warming. Among abstracts expressing a position on AGW, 97.1% endorsed the consensus position that humans are causing global warming. [Emphasis added.]


Pause here and note that it is odd to see that some folks apparently haven’t gotten the memo that you’re not supposed to call it “global warming”—“climate change” is the term of art now. Anyway, to continue, read this slowly and carefully:

Among abstracts expressing a position on AGW, 97.1% endorsed the consensus position that humans are causing global warming. In a second phase of this study, we invited authors to rate their own papers. Compared to abstract ratings, a smaller percentage of self-rated papers expressed no position on AGW (35.5%). Among self-rated papers expressing a position on AGW, 97.2% endorsed the consensus.


Let’s translate: Among the one-third of papers that “endorse” the “consensus,” there is near unanimity. In other words, among people who agree with the consensus, nearly all of them agree with the consensus. Again—the only mystery here is that the number isn’t 100 percent. Perhaps this would have been too embarrassing to report, like a North Korean election. For this exercise all climate scientists may as well be called named Kim Jong Il.

The plot thickens. Prof. Cook refused to share his data with anyone. Shades of the East Anglia mob and their tree ring data. But also like the East Anglia mob, someone at the University of Queensland left the data in the ether of the internet, and blogger Brandon Shollenberger came across it and starting noting its weaknesses. Then the predictable thing happened: the University of Queensland claims that the data was hacked, and sent Shollenbeger a cease-and-desist letter. That just speaks lots of confidence and transparency, doesn’t it?

Brilliant, except:

1. If coal and oil invest in research, you presume it is biased. However, if government invests in research ALL OF ONE TYPE (pro-AGW), you presume it is unbiased. It seems to me you might be biased.

2. Your long quote has nothing to do with Lennart Bengtsson, who was the subject of my post.

Is it a safe presumption that research paid for by oil and gas might be biased?
If governments, or universities, invest in research to learn about changes in the atmosphere and its effects on climate ... is that presumably biased? What we know about Dr. Soons work indicates this is the case.

There is a large financial reward to be gained by the oil and gas industry..... (and the coal industry)
Researchers who do good research, that produces reputable reports that pass peer review.... will be rewarded with future support. But there is no evidence that the results of the research must be predetermined... (If you can find some Fate, have at it. All I've ever seen is inuendo)
In fact, if there was credible, ground breaking work that disputed the current consensus, that could hold up to scrutiny and review, its likely that the scientists would gain more than if their work added to the consensus. Because genuine discovery comes with rewards...

Yeah it does...
Lennart's being shunned by his community for ignoring reality.
If he had joined the Flat Earth society, he would be shunned too.

Its interesting that there is some similarity here concerning our conversation about tolerance...
Apparently the scientific community finds Lennarts position intolerable. That is something they can't tolerate.
And they've pressured him, through criticism mostly, that he can't handle. Apparently because he really doesn't have the evidence to support his scepticism that hols up to the scrutiny he's receiving...
Now, it might be said that at some point many scientists were lone voices expressing new ideas that the majority of their peers would not accept... (Gallileo for instance. Though in truth the Greeks knew the world was a globe, and he was just rediscovering a fact.)
The difference is that as Galileo's information was scrutinized it held up. And as new inquiries into the area added information, the truth of his position became ever more clear.

we've known for almost 200 years that CO2 holds more energy than most other atmospheric gasses. Its a fact. That increasing the concentration of CO2 in the atmosphere will increase the energy held in the atmosphere has never been disputed with any information.
And the more that is learned about the work Dr, Soon and others ... the alternatives to why the climate is warming (also an observed fact, albeit one that some seek to confuse by starting data points for warming in 1998 rather than say 1898...) have fallen away.

1. YOU introduced Soon, not me. I neither vouch for him or accuse him.

This is like asking me to find proof that the current government is anti-coal. You either believe what they say and do or you don't. They could not be more clear. Please point to any research the government has supported that has come out against AGW. It's not innuendo. It's 100%.

Not true. I point to Lennart Bengtsson (not Soon) and what happened to him? Were his questions examined, or was he cajoled/threatened/cowed into submission? Since you seem to have skipped it:

Lennart Bengtsson, a research fellow at the University of Reading and one of the authors of the study, said he suspected that intolerance of dissenting views on climate science was preventing his paper from being published. “The problem we now have in the climate community is that some scientists are mixing up their scientific role with that of a climate activist,” he added.

Professor Bengtsson’s paper challenged the finding of the UN’s Intergovernmental Panel on Climate Change (IPCC) that the global average temperature would rise by up to 4.5C if greenhouse gases in the atmosphere were allowed to double. It suggested that the climate might be much less sensitive to greenhouse gases than had been claimed by the IPCC in its report last September, and recommended that more work be carried out “to reduce the underlying uncertainty”.

The five contributing scientists, from America and Sweden, submitted the paper to Environmental Research Letters, one of the most highly regarded journals, at the end of last year but were told in February that it had been rejected.

A scientist asked by the journal to assess the paper under the peer review process wrote that he strongly advised against publishing it because it was “less than helpful”. The unnamed scientist concluded: “Actually it is harmful as it opens the door for oversimplified claims of ‘errors’ and worse from the climate sceptics media side.”

Professor Bengtsson resigned from the advisory board of Lord Lawson of Blaby’s climate sceptic think-tank this week after being subjected to what he described as McCarthy-style pressure from fellow academics. . .

Professor Bengtsson, the former director of the Max Planck Institute for Meteorology in Hamburg, said he accepted that emissions would increase the global average temperature but the key question was how quickly.

He added that it was “utterly unacceptable” to advise against publishing a paper on the ground that the findings might be used by climate sceptics to advance their arguments. “It is an indication of how science is gradually being influenced by political views. The reality hasn’t been keeping up with the [computer] models. Therefore, if people are proposing to do major changes to the world’s economic system we must have much more solid information.”

Um, if you made a mistake, why not admit it rather than just lie? That article is about Soon, not Bengtsson. You should have the capacity to know the difference.

I think.

Its interesting that there is some similarity here concerning our conversation about tolerance...
Apparently the scientific community finds Lennarts (sic) position intolerable. That is something they can't tolerate.
And they've pressured him, through criticism mostly, that he can't handle. Apparently because he really doesn't have the evidence to support his scepticism that hols (sic) up to the scrutiny he's receiving...


Five scientists do research that calls some conclusions into question and the response is one scientist saying it could potentially make the work of critics simpler, therefore it should not be published. Is that science or suppression?

And, you seem to revel in the McCarthy-like tactics used against him. Nice.

That's what I am saying: it more closely resembles Scientology than Science. True science does not fear questions; it embraces them.

Now, it might be said that at some point many scientists were lone voices expressing new ideas that the majority of their peers would not accept... (Gallileo for instance. Though in truth the Greeks knew the world was a globe, and he was just rediscovering a fact.)
The difference is that as Galileo's information was scrutinized it held up. And as new inquiries into the area added information, the truth of his position became ever more clear.


Here's where you (again) miss the boat. The scientist who suggested rejecting Bengtsson's article did not do so on the basis of flaws in the paper. He was motivated by concerns that were neither mathematical nor scientific.

Suppression is not science.

I think it is the guy from that blog who is being misleading, DF. first thing he does is ask whether the scientists actually read the 11,000 papers. Well, no. They did read the abstracts which is basically a short synopsis of the paper. If he does not get that difference then he should not be posting on this topic. If he does, then he is trying to mislead readers with that question.
Secondly, he mentions that over 2/3 of the papers did not state any position at all on climate change. Ok, but you still have 3,000 or so that do. That is still plenty of data.
Next, he examines the second part of the study where the authors of the study were asked to rate their papers with regard to climate change (please note that they were not asking the scientists as to their personal views on climate change). There, the scientists self-rated at a much higher rate with only 35% saying that their papers did not take a position on climate rate. But as to both the review of the abstracts by the authors of the study and the scientists ratings the papers themselves there was a consensus that human activity caused climate change.
This is where this critic of the 97.1 goes off the deep end. He says that the among the one-third of papers that endorse the consensus, nearly all of them endorse the consensus. Then he compares it to a totalitarian election asking why isn't it 100 percent (yeah why would it not be 100 percent)
Well, he's either an utter idiot or a liar or both. He quoted the results of the study (which was nice so we could point out his idiocy). It is not the case that the study found that among the papers that endorsed the consensus 97 percent endorsed the consensus. He is trying to imply that 2/3 of papers don't endorse the consensus. The results were that of the abstracts reviewed only 1/3 stated any position at all on climate change and of those there was a 97.1 consensus on those that did (and with regard to self-rating by authors of paper 65 percent felt that their papers stated a position on global warming and there was a 97.2 consensus) .
Again, the study did not that only one-third of the papers endorsed the consensus and then go to find that of those papers there was a 97.1 consensus. That is a ludicrous interpretation. It took a look at 11,000 abstracts and found that 1/3 took a position on climate change at all and of those 1/3 that took a position there was a 97.1 consensus.
I know you posted this in good faith,DF but this guy makes me mad with his utter disregard for the truth.

Oh come on. How do you expect to be taken seriously when you make pathetic arguments like this ?

By all means feel free to point out the specific aspects of Bengtsson's work which equate to flat-earthery. I'm sure you've read his published work and are eminently qualified to pass judgement. Oh wait, you haven't and you aren't. I'm willing to bet you couldn't even tell us what it is that Lennart Bengtsson has actually said.
