The paper focuses on a chart of the Earth’s surface temperatures going back to 1880. Asness, who wrote the paper along with his co-worker Aaron Brown, does not deny that global temperatures are rising. But he says temperatures are rising at much slower rate than many suggest. What’s more, Asness and Brown say, based on the current pace of global warming, it will take another 500 years before the changes become a real problem.But hey, Cliff Asness runs one of the world's largest hedge funds, so he must be an expert on everything, right, including all of science? Else how did he get rich?
Asness writes that he is not trying to deny the science of climate change, but that he is just looking at the data and what it says on its own. He offers other observations about climate change, including that the decline in Arctic sea ice or rising sea levels could just be the result of a mild increase in temperatures and not a sign that the world is about to get dramatically warmer.
“I’m not sure about the idea of beating people about the head and shoulders, but within less than a year, you will look like complete fools (if you buy this crap)Hansen is, of course, right.

The modelling approach is inherently of no value for predicting future temperature with any calculable certainty because of the difficulty of specifying the initial conditions of a sufficiently fine grained spatio-temporal grid of a large number of variables with sufficient precision prior to multiple iterations.

Doubling times of 10, 20 or 40 years yield sea level rise of several meters in 50, 100 or 200 years.But there's no evidence of a doubling time of 10, 20 or 40 years. The latest Aviso sea level data now shows, over the satellite era, an acceleration of 0.026 mm/yr2 over a sea level rise of 3.36 mm/yr -- that's an acceleration/SLR of 0.72% per year, or a doubling time of 97 years.
In an email to Slate, Ruth Mottram, a climate scientist who was skeptical of the initial draft, calls the final study “considerably improved.” Mottram, who specializes in studying the Greenland ice sheet, said “the scenario they sketch out is implausible, though perhaps not impossible … it’s frankly terrifying.”"Perhaps not impossible" isn't exactly a ringing endorsement that says the paper deserves to be part of any "canon."
Richard Alley, a key figure in the polar research community, also gave the Hansen study cautious praise. “It usefully reminds us that large and rapid changes are possible,” Alley said in an email, and that “uncertainties are clearly loaded on the “bad” side.” Alley stressed, though, that the Hansen result was only a single study, and wasn’t detailed enough to be used as a firm prediction.
Kim Cobb, a climate scientist specializing in ancient climate change, agrees that the Hansen study is useful mostly because it explores the worst-case scenario. “My bet is on non-linearities kicking in that we cannot yet measure adequately,” Cobb said in an email. “In that way I think it’s important to explore the upper limits.”Instead of the support Holthaus apparently thinks these give to the canonization for Hansen's paper, these are actually quite tepid remarks that duly show respect for the paper's authors without going anywhere close to endorsing their conclusions.
"If we’ve learned any lessons during the past few decades, perhaps the most important is that preservation of our environment is not a partisan challenge; it’s common sense. Our physical health, our social happiness, and our economic wellbeing will be sustained only by all of us working in partnership as thoughtful, effective stewards of our natural resources."
Since the 1950s, the tribe has lost 98 percent of its land to rising sea levels, coastal erosion and flooding. The island, about 50 miles south of New Orleans, once covered 15,000 acres, but the land has eroded to a tiny strip measuring a quarter-mile wide by a half-mile long, according to a report by Northern Arizona University....Also from Inside Climate News: Flood Damage Costs Will Rise Faster Than Sea Levels, Study Says; Research begins to show that damage will increase exponentially and aims to give coastal cities a way to prepare for them. (We need a term, akin to the "Singularity," for the moment people realize climate change is at their doorstep and it's too late to fix it.)
The threat to the tribe has come not only from climate change but from other human activities such as oil and gas development that has caused a decline in sediment deposits from the Mississippi River.
"Who is the aggrieved party [from climate change]...? What are the monetary damages...? Lynch's suit would be unlike the tobacco settlement because there states were paying out large amounts of money for the health care of smokers.... [They had clear standing as an aggrieved party who suffered financially from the tobacco company's lies.]And he said
"demonizing people" would be a mistake.In a panel discussion in the last half-hour of the session I asked the panel for their reactions to Lynch's testimony. Hoffman was on the panel and called it a "horrible idea," "a similar tactic to what was done to Michael Mann," and that people are surely already coming up with "metaphors to Copernicus."
As I have mentioned on a number of occasions in this space, we believe the risks of climate change are real and those risks warrant constructive action by both policymakers and the business community.though who knows what ExxonMobile is saying (and doing) out of the other side of their mouth. A couple of decades ago, perhaps they thought the science was too uncertain to mention (and, despite what any of their internal scientists were saying, it was according to IPCC assessments I and II). Or they thought that any damage was small, or would be small, and offset by agricultural gains and other benefits. They might say that their oil used for personal and public transportation was and is a huge benefit to society? Or, in the time before electric cars, are people suffering an attack of appendicitis supposed to ride their bike to the ER? They could argue on all these points and more that their product gave more benefit than harm.

"The ability to understand and explain extreme events in the context of climate change has developed very rapidly over the past decade. In the past, a typical climate scientist’s response to questions about climate change’s role in any given extreme weather event was “we cannot attribute any single event to climate change.” The science has advanced to the point that this is no longer true as an unqualified blanket statement. In many cases, it is now often possible to make and defend quantitative statements about the extent to which human-induced climate change (or another causal factor, such as a specific mode of natural variability) has influenced either the magnitude or the probability of occurrence of specific types of events or event classes."EOS: Scientists Find the Point of No Return for Antarctic Ice Cap -- about 600 ppmv
An America in which Trump can represent one of the major parties feels like a very different country from the one many of us thought we lived in. Like a lot of people, I was much too complacent. It can happen here, and it might.Here is picture from today's Trump rally, in Florida, covered by Slate, where he (Drumpf) asked people to raise their hand to pledge to vote for him.
The Oregon Legislature just voted today to eliminate coal generation [and ban its import, after 2030] from the state's future and committed its largest utilities to supply at least half of their electricity from renewable resources by 2040. Combined with Oregon's existing hydroelectric base, that means the state will be on track for an electricity system that's 70 to 90 percent carbon-free by that date. The legislation will make Oregon's energy among the cleanest in the country, and puts the state in the growing top tier of renewable energy standards, along with California, New York and Hawaii.More at the NRDC's blog.
The new dataset shows substantially increased global-scale warming relative to the previous version of the dataset, particularly after 1998. The new dataset shows more warming than most other middle tropospheric data records constructed from the same set of satellites. We also show that the new dataset is consistent with long-term changes in total column water vapor over the tropical oceans, lending support to its long-term accuracy.
