I guess the conspirators got him… 🙂 That still shows indeed the march of science, somehow the conclusions that are more supported are deemed false by a few blogessors just because of the progress itself. ---

The current search of the oceans proves that even the IPCC doesn’t believe the science is settled (as if science is ever settled). And another straw man, the scientists are not reporting that is settled, what it can say is that the prevalence of the evidence is telling us to act, for even less probabilities of harm we decided to act to regulate tobacco smoke. This was also ignored then: > **[RealClimate: Unsettled Science](https://www.realclimate.org/index.php/archives/2009/12/unsettled-science/)** > > RealClimate: Unusually, I'm in complete agreement with a recent headline on the Wall Street Journal op-ed page: "The Climate Science Isn't Settled" The article below is the same mix of innuendo and misrepresentation that its author normally writes,... > [@](#): > > The phrase “the science is settled” is associated almost 100% with contrarian comments on climate and is usually a paraphrase of what ‘some scientists’ are supposed to have said. The reality is that it depends very much on what you are talking about and I have never heard any scientist say this in any general context – at a recent meeting I was at, someone claimed that this had been said by the participants and he was roundly shouted down by the assembled experts. > > The reason why no scientist has said this is because they know full well that knowledge about science is not binary – science isn’t either settled or not settled. This is a false and misleading dichotomy. Instead, we know things with varying degrees of confidence – for instance, conservation of energy is pretty well accepted, as is the theory of gravity (despite continuing interest in what happens at very small scales or very high energies) , while the exact nature of dark matter is still unclear. The forced binary distinction implicit in the phrase is designed to misleadingly relegate anything about which there is still uncertainty to the category of completely unknown. i.e. that since we don’t know everything, we know nothing. > > In the climate field, there are a number of issues which are no longer subject to fundamental debate in the community. The existence of the greenhouse effect, the increase in CO2 (and other GHGs) over the last hundred years and its human cause, and the fact the planet warmed significantly over the 20th Century are not much in doubt. IPCC described these factors as ‘virtually certain’ or ‘unequivocal’. The attribution of the warming over the last 50 years to human activity is also pretty well established – that is ‘highly likely’ and the anticipation that further warming will continue as CO2 levels continue to rise is a well supported conclusion. To the extent that anyone has said that the scientific debate is over, this is what they are referring to. In answer to colloquial questions like “Is anthropogenic warming real?”, the answer is yes with high confidence. > > But no scientists would be scientists if they thought there was nothing left to find out. Think of the science as a large building, with foundations reaching back to the 19th Century and a whole edifice of knowledge built upon them. The community spends most of its time trying to add a brick here or a brick there and slowly adding to the construction. The idea that the ‘science is settled’ is equivalent to stating that the building is complete and that nothing further can be added. Obviously that is false – new bricks (and windows and decoration and interior designs) are being added and argued about all the time. However, while the science may not be settled, we can still tell what kind of building we have and what the overall picture looks like. Arguments over whether a single brick should be blue or yellow don’t change the building from a skyscraper to a mud hut. > > The IPCC reports should be required reading for anyone who thinks that scientists think that the ‘science is settled’ – the vast array of uncertainties that are discussed and dissected puts that notion to bed immediately. ---

> [@FXMastermind](#): > > This is almost like the Pope turning around and saying Catholicism is nonsense. > Something I noticed years ago. But nice to see a real climate expert say it. Nope, he is like a retired Mormon telling the Pope what to do. He is not really an expert climate scientist and he retired from ecology work a long time ago. And as a result he gets things wrong: > [@](#): > > In his most recent book, “The Vanishing Face of Gaia”,[22] he rejects scientific modelling that disagrees with the scientific findings that sea levels are rising faster, and Arctic ice is melting faster, than the models predict and he suggests that we may already be beyond the tipping point of terrestrial climate into a permanently hot state. Given these conditions, Lovelock expects human civilization will be hard pressed to survive. He expects the change to be similar to the Paleocene-Eocene Thermal Maximum when atmospheric concentration of CO2 was 450 ppm. At that point the Arctic Ocean was 23 °C and had crocodiles in it,[23][24] with the rest of the world mostly scrub and desert. Indeed, he even recently gave up on that, so the Telegraph must think that a “never mind” is ok for current contrarian expertise. Someday the denier media like the Telegraph will learn about false equivalency. And what an expert is supposed to be. [![](https://img.youtube.com/vi/ZpcwyeGQlA8/hqdefault.jpg "Potholer54: "9.

While I disagreed with his doomsday nonsense, he seems to have become far more rational of late. > [@](#): > > In an April 2012 interview, aired on MSNBC, Lovelock stated that he had been “alarmist”, using the words “All right, I made a mistake,” about the timing of climate change and noted the documentary An Inconvenient Truth and the book The Weather Makers as examples of the same kind of alarmism. Lovelock still believes the climate to be warming although the rate of change is not as he once thought, he admitted that he had been “extrapolating too far." He believes that climate change is still happening, but it will be felt farther in the future.[32] Of the claims “the science is settled” on global warming he states:[33] > “One thing that being a scientist has taught me is that you can never be certain about anything. You never know the truth. You can only approach it and hope to get a bit nearer to it each time. You iterate towards the truth.

The Los Angeles Times reported in 2009 that Lovelock, who is known for formulating the Gaia hypothesis in the 1960s, considered those reports “too optimistic, constrained by ‘consensus’ (a word that makes his teeth itch) and wedded to computer models.” Climate experts, in turn, distanced themselves from Lovelock’s doomsday rhetoric. The IPCC’s chairman, Rajendra Pachauri, told Agence France-Presse in September 2009 that Lovelock’s predictions were “highly improbable”; [RealClimate.org](http://RealClimate.org), a blog written by climate scientists, noted in 2006 that Lovelock’s claims weren’t supported by scientific research. Watch the video I linked to, it is a very good lesson on who to look for regarding who is an expert and who is not. The reality is that it is the contrarians that do rely a lot on non experts, scientists who are retired for a long time in their fields, or experts in other fields that are not what you really need. ---

You drastically misunderstand the purpose of the IPCC and the nature of climate science. Scientific knowledge is cumulative over time, especially in a very complex and rapidly advancing field such as climate science, and even the best assessment of the current knowledge of such a field soon becomes out-of-date. The IPCC’s multiple Assessment Reports are updates, not fixes. ---

Indeed **Kimstu**. I should add a warning to these threads, others that do understand the science should be careful to not wonder aloud how it is possible that a graph of past temperatures from an early report by the IPCC, is accepted by contrarians as “the truth” while better supported graphs published more recently by the same organization are just lies. You will only get a headache. ---

Yeah, cause wondering aloud is dangerous. Also, the evidence for much warmer periods than the present is overwhelming. In fact, it’s beyond reproach. The people trying to sell you that now is the warmest ever, and we are in grave danger, they are deluded. ---

So much for telling others that you understand the science. Scientists already know that there were past warmer periods, and that CO2 was one of the elements of those past warnings. Thanks to paleoclimatology is that science can tell you that as CO2 has not reformed from what it did in the past, it is clear that we can not go using the atmosphere as a sewer and to not expect that to not drive the current warming observed.

The overwhelming consensus of scientific studies on climate indicates that most of the observed increase in global average temperatures since the latter part of the 20th century is very likely due to human activities, primarily from increases in greenhouse gas concentrations resulting from the burning of fossil fuels. > > While there is public debate about the attribution of recent climate change, it is not a strong feature of the discussions of climate scientists. or the peer reviewed literature. This is why this document uses the strong language “overwhelming consensus”. A variety of studies have noted that while most American adults believe climate change is happening, less than half of American adults think that climate scientists agree-- i.e., that there is a scientific consensus-- that human activities are a major cause of warming.
