Judge Orders EPA To Produce Science Behind Pruitt's Climate Claims (scientificamerican.com)
EPA must produce the opposing body of science Administrator Scott Pruitt has relied upon to claim that humans are not the primary drivers of global warming, a federal judge has ruled. From a report: The EPA boss has so far resisted attempts to show the science backing up his claims. His critics say such evidence doesn't exist, even as Pruitt has called for greater science transparency at the agency. Now, a court case may compel him to produce research that attempts to contradict the mountain of peer-reviewed studies collected by the world's top science agencies over decades that show humans are warming the planet at an unprecedented pace through the burning of fossil fuels. Not long after he took over as EPA administrator, Pruitt appeared on CNBC's "Squawk Box," where he was asked about carbon dioxide and climate change. He said, "I would not agree that it's a primary contributor to the global warming that we see." The next day, Public Employees for Environmental Responsibility, or PEER, filed a Freedom of Information Act request seeking the studies Pruitt used to make his claims. Specifically, the group requested "EPA documents that support the conclusion that human activity is not the largest factor driving global climate change." On Friday, the chief judge of the U.S. District Court for the District of Columbia, Beryl Howell, ordered the agency to comply.
It was nice knowing you. But now you're just getting in the way of the current administration. You were signed into law by a Democrat, so expect to be repealed soon by a Republican majority Congress.
Consider that the United States obesity epidemic has been caused by a government policy to promote carbohydrate consumption and discourage fat consumption. That policy was based on scientific research.
Not true.
These recommendations emanated from hearings held in the mid-to-late 1970s by the Senate Select Committee on Nutrition and Human Needs, despite a “boisterous mob of critics,” including those within the scientific community who pleaded with the Committee to wait for more research “before we make announcements to the American public.” In response, Committee Chairman Sen. McGovern responded that “Senators don’t have the luxury that the research scientist does of waiting until every last shred of evidence is in.”
This was a classic case of, "We have to do something, this is something, we have to do this." The scientists were very clear that there was no research supporting the policy recommendation.
Nope, no sig
Here is an interesting one
An interesting paper, thanks. I'd say the authors have substantially contributed to our understanding of the long term evolution of ice sheets, and their models will (within boundaries and with significant uncertainties) go some way towards predicting how the northern hemisphere ice sheets will change over the coming decades.
Still, it's worth pointing out that the fact that it was briefly warmer 5000 years ago doesn't contradict either the notions that CO2 traps heat or that increasing CO2 levels in the atmosphere causes global warming, or the notion that mankind is responsible for rapidly increasing the concentration of atmospheric CO2.
As regards your other nugget:
...which is what led Phil Jones, Director of the CRU of East Anglia and a primary contributor to the IPCC, to agree that
according to the global temperature record used by the IPCC, the rates of global warming from 1860-1880, 1910-1940 and 1975-1998 were identical
. So if the heating over those periods - two well before the rapid rise in CO2 - are the same as the "big trigger" that caused the whole IPCC/global warming issue in the first place, then how do we know that it's because of CO2?
That's a good question, and I guess the answer is "We don't, completely". Numerous factors influence the climate, not just levels of CO2. The fact remains though that we are rapidly increasing the levels of atmospheric CO2, whereas we have no control over the other factors.
I feel it's worth pointing out, just in case someone reads your post and doesn't follow the links, a couple of things:
Firstly, unlike your "quote" which is actually the question that was asked (missing the question mark), Phil Jones' response was that "the warming rates for all 4 periods are similar and not statistically significantly different from each other. Ascribing false certainty, as you do, might lead one to question the integrity of your argument.
Secondly, it's also worth pointing out that, since the rates are similar, it also follows that temperatures have been consistently rising, and are continuing to rise. One might think that this alone justifies concern over what will happen as they continue to rise, with regards sea levels, weather patterns and behaviour, and so on.
Finally, since you linked to the article, why don't we give Phil's answer to the question "Would it be reasonable looking at the same scientific evidence to take the view that recent warming is not predominantly manmade?". His answer: "No"
