Worst global warming predictions likely the most accurate, study finds
Just another prophecy, and an act of faith. They think that models which provide the best fit to the past will predict the future. Yet that is exactly what does NOT happen. Fitting a model to the past does NOT predict the future. All the Warmists' troubles would be over if it did
The worst-case predictions regarding the effects of global warming are the most likely to be true, a new study published this week has warned.
"Our study indicates that if emissions follow a commonly used business-as-usual scenario, there is a 93 per cent chance that global warming will exceed 4°C by the end of this century," Dr. Ken Caldeira, an atmospheric scientist at the Carnegie Institution for Science, who co-authored the study told The Independent.
This research shows a dramatic increase over previous estimates, which placed the likelihood of such a drastic increase at just 62 percent.
Since the Earth's climate system is incredibly complex, different scientists have put forward different models to determine how fast the planet is warming. This has resulted in a range of predictions, some more dire than others.
The new study, published in the academic journal "Nature", aimed to determine whether the upper or lower-end estimates are more reliable.
Caldeira and co-author Dr. Patrick Brown looked at models that proved to be the best at simulating climate patterns in the recent past. They reasoned that these models would present the most accurate estimates.
"It makes sense that the models that do the best job at simulating today's observations might be the models with the most reliable predictions," Caldeira explained.
According to the researchers' conclusions, models with higher estimates are more likely to be accurate, meaning the degree of warming is likely 0.5°C higher than previously accepted.
Scientist that weren't involved with the research have come out in support of the findings as well.
"There have been many previous studies trying to compare climate models with measurements of past surface-temperature, but these have not proved very conclusive in reducing the uncertainty in the range of future temperature projections," Professor William Collins, a meteorologist at the University of Reading, said.
Professor Collins explained that the new study "breaks the issue down into the fundamental building blocks of climate change."
While the overwhelming majority of climatologists and environmental scientists agree that climate change is a problem accelerated by human activity, representatives from the fossil fuel industry and the administration of U.S. President Donald Trump have dismissed such claims.
However, with more and more research backing worst-case predictions, complete dismissal of such findings becomes increasingly difficult. This study in particular addresses one key point climate change deniers often seize upon: the uncertainty that comes with so many different climate models.
"This study undermines that logic," Dr. Brown told MIT Technology Review. "There are problems with climate models, but the ones that are most accurate are the ones that produce the most warming in the future."

Susan Crockford on the starving polar bear story
I saw this story when it first came out and thought it was too shallow to be worth comment. Bears die. How do we know what this one was dying of? Nobody made any attempt to find out. It was just asserted that global warming was the culprit. Anyway, it may be useful to present some comments from a bear expert -- JR
In August, this bear would have been only recently off the sea ice: since most bears are at their fattest at this time of year, something unusual had to have affected his ability to hunt or feed on the kills he made when other bears around him did not starve and die. It could have been something as simple as being out-competed for food in the spring by older animals.
But if sea ice loss due to man-made global warming had been the culprit, this bear would not have been the only one starving: the landscape would have been littered with carcasses. This was one bear dying a gruesome death as happens in the wild all the time (there is no suggestion that a necropsy was done to determine cause of death, just like Stirling’s bear that supposedly died of climate change.)
In fact, research done by polar bear specialsts that work in the field shows that the most common natural cause of death for polar bears is starvation, resulting from one cause or another (too young, too old, injured, sick) (Amstrup 2003):
“Starvation of independent young as well as very old animals must account for much of the natural mortality among polar bears… Also, age structure data show that subadults aged 2-5years survive at lower rates than adults (Amstrup 1995), probably because they are still learning hunting and survival skills.”
…
“I once observed a 3-year-old subadult that weighed only 70 kg in November. This was near the end of the autumn period in which Beaufort Sea bears reach their peak weights (Durner and Amstrup 1996), and his cohorts at that time weighed in excess of 200 kg. This young animal apparently had not learned the skills needed to survive and was starving to death.” [my bold]
But as Mittermeier has made clear, facts don’t matter in cases like this Somerset Island bear’s death: it’s all about the message.
I’ve asked this question before because it speaks to the present political climate: where were the appeals to help the many starving polar bears back in the spring of 1974 when females with newborn cubs were starving in the Eastern Beaufort Sea because the thick spring ice drove ringed seals away before they gave birth (Stirling 2002)?
Here is what Stirling and Lunn (1997:177) had to say about the mortality event of 1974 that they witnessed:
“…in the spring of 1974, when ringed seal pups first became scarce, we capture two very thin lone adult female polar bears that had nursed recently, from which we deduced they had already lost their litters. A third emaciated female was accompanied by two cubs which were so thin that one could barely walk. We have not seen females with cubs in this condition in the Beaufort Sea, or elsewhere in the Arctic, before or since.”
What Stirling and Lunn witnessed and documented is scientific evidence that natural variation in spring sea ice can have devastating effects on polar bears, including mass mortality events (Crockford 2017). However, we have not seen any similar mass starvation events that have been conclusively shown to be caused by low summer sea ice.
One starving bear is not scientific evidence that man-made global warming has already negatively affected polar bears but it is evidence that some activists will use any ploy to advance their agenda and increase donations.
UPDATE: In an interview yesterday published in the Victoria Times-Colonist (my home town) with photographer Nicklen stated:
“Nicklen is careful about drawing conclusions from his pictures, noting that many people look to poke holes in what’s being said about things like the disappearance of sea ice from the North.... “Ice is melting earlier every spring and freezing later every fall,” Nicklen said. “Bears are designed to go as much as two months without ice, but they are not designed to go four or five months without ice. “Well, this [the video] is what it actually looks like when polar bears are stranded on land.”
Nicklen should do a bit more reading: polar bears in Western Hudson Bay routinely go four to five months without ice. Four months was normal in the good old days (ca. 1980) and almost five months in some recent years (Castro de la Guardia et al. 2017; Cherry et al. 2013; Ramsay and Stirling 1988; Stirling and Lunn 1997). WHB pregnant females spend 8 months or more on land with no ill effects that can conclusively be blamed on a slightly longer time without ice (Crockford 2017). Southern Hudson Bay polar bears spend a similar amount of time without ice (Obbard et al. 2016), see this post (with references).

Does Bitcoin Really Cause Global Warming?
The green movement has found many things in modern life that cause global warming, but the latest really left us scratching our heads: Trading Bitcoins.
At this point it might be easier to ask, is there anything that doesn’t cause global warming?
No, it’s not a joke. Just about anything these days (Hat tip: The Daily Caller) even remotely connected to civilization, human flourishing, and comfort is, we’re told, a “cause” of global warming. It’s a crucial element of the Global Warming religion, which has only waxed even as real religion has waned.
Both Vox and The New Republic pointed out that in order to “mine” Bitcoins on the computer, it takes a lot of energy. The argument goes that, since most Bitcoins now are mined by Chinese citizens and since China derives a growing amount of its energy from cheap-but-dirty coal, Bitcoins are increasing the amount of CO2 in the air.
And more CO2 equals more warming, QED.
“Bitcoins are contributing to the warming of the atmosphere without providing a significant public benefit in return,” writes The New Republic’s Emily Atkin.
Of course, Atkin must possess special, recondite knowledge about exactly how warm the Earth should be at all times, and also about what precisely constitutes a “significant public benefit” from Bitcoins.
Meanwhile, over at Vox, warming worrier Umair Irfan frets that Bitcoin mining on the web uses huge amounts of energy, “on par with the energy use of the entire country of Morocco, more than 19 European countries, and roughly 0.7% of total energy demand in the United States, equal to 2.8 million U.S. households.”
Sounds like a lot. But the energy estimates he uses are in dispute, as Irfan, to his credit, points out.
The important point is that people find Bitcoins useful, or they wouldn’t exist. That’s one of the reasons why a single Bitcoin is today priced at over $16,000 — up from $1 in April of 2011.
With a global value now estimated a $167 billion, Bitcoins are clearly viewed as a worthwhile expenditure of time, money and energy.
Moreover, the total number of Bitcoins is, by rule, capped. So the amount of “mining” of Bitcoins on the internet — Bitcoins are “mined” when market participants use their own computer and a special algorithm to validate certain highly secure transactions, thereby earning Bitcoins for doing it — will at some point inevitably begin to decline. It will just take too much effort and cost too much.
Even so, these writers’ views really go to the heart of the global-warming belief system: Since human civilization requires lots of energy, and it does, everything associated with human civilization must cause global warming. Everything.
You can take this to its absurd ends, and that’s exactly what they do. Nothing humans do, no matter how valuable or life-enhancing it is, is immune from criticism.
Some global warmists would even forcibly limit population in order to prevent warming. Some have even wistfully hoped for a mass human extinction.
Of course, those who now issue jeremiads about the climate change threat posed by Bitcoins likely won’t give up their electric cars soon, which are only as clean as the power plants that charge them.
Nor will they stop flying on fuel-guzzling commercial jets to attend the next global-warming conference, wherever it is.
Nor will they stop swiping their ATM card at the local Starbucks to buy their daily triple-soy-latte, which, by requiring energy, also contributes to global warming.
No, the fact is, human civilization and all the wonderful things it entails requires massive amounts of energy to work. And that’s not bad: Next time you’re in a hospital or in an elevator in a super-tall building, give silent thanks for the steady, reliable supply of energy that helps make it all possible.
As for concerns about global warming, the science behind them is rather dubious. Even so, those concerns would pretty much disappear if the greenies would embrace the latest, and extremely safe, technology for nuclear energy.
It’s a nearly endless supply of clean electricity that produces no CO2. So the supposed “threat” of global warming could end, while the rest of us could keep our civilization. Win-win!
Meanwhile, for those of you in the Bitcoin world, don’t be green-shamed into stopping your activities. You’re not the real enemy of these warming fanatics; civilization is.

Keystone is anti-hydrocarbon zealotry in microcosm
Radical environmentalists prefer dangerous, inhumane, ecologically destructive alternatives
Paul Driessen
The Nebraska Public Service Commission (NPSC) recently voted to approve the state’s segment of the 1,200-mile Keystone XL Pipeline. While that would appear to allow construction to move forward, more obstacles loom before KXL can finally bring North Dakota and Canadian crude oil to Texas refineries.
Commissioners who voted against approval have raised objections, some landowners still object to the pipeline crossing their lands, other landowners were not aware that the new route will cross their properties, and environmentalists plan more lawsuits to stop TransCanada’s plans to finish Keystone.
Further complicating matters, the NSPC-approved route is not the company’s preferred path through the Cornhusker State. A spokesman said project engineers will have to assess how much the newly revised route will affect construction schedules and costs, on top of the $3 billion it already spent on KXL.
The imbroglio is a tiny facet of the ideological green movement’s implacable opposition to carbon-based energy. Rooted in climate change dogma, its “keep it in the ground” mantra has become a rallying cry for nasty campaigns against pipeline construction, existing pipelines, drilling and even sand destined for fracking operations. Police increasingly have to deal with masked thugs, mountains of toxic trash, murder threats and even the possibility of improvised bombs hidden in “peaceful protesters” encampments.
The attitudes and actions underscore the increasing power and recalcitrance of $13-billion-per-year Big Green industry, and how little fundamental facts affect its thinking. If the radicals believe there is an ecological or climate risk, they feel justified in using intimidation, criminal sanctions, and even force, violence and eco-terror to impose their will. Whatever they cannot make off limits via Antiquities Act, wilderness or other land use designations, they intend to lock up or shut down by other means.
The most delayed and litigated pipeline in U.S. history, KXL has stirred controversy for over a decade. Proponents say it is a necessary, safe, effective way to transport crude oil to refineries that produce fuel for vehicles and raw materials for countless petrochemical products. In fact, segments of Keystone have already been in operation for several years, delivering crude oil to refineries in Illinois and Texas.
A new, shorter, more direct route – Keystone XL, running diagonally through Wyoming, the Dakotas and Nebraska – would be less expensive and safer. The northern portions were approved years ago, but the Nebraska section encountered prolonged opposition from climate alarmists and President Obama.
TransCanada had already agreed to move the route away from environmentally sensitive wetlands known as the Nebraska Sandhills. The NPSC decision shifted the pipeline further away from Sandhills. Diehard opponents say all pipelines are inherently unsafe, prolong the use of “climate-damaging” fossil fuels, and will become obsolete relics as America shifts entirely to renewable energy in a utopian decade or so.
The United States already has 160,000 miles of liquid petroleum pipelines, 300,000 miles of natural gas transmission pipelines, and 2,200,000 miles of local gas distribution pipelines. Skilled builders will use the latest steel, valve, monitoring and other technologies to build the KXL segment and prevent spills.
No one can guarantee that spills will never occur. A recent older Keystone pipeline break in South Dakota caused a 5,000-barrel leak. However, the Keystone and KXL lines traverse mostly rural areas, whereas truck and rail alternatives go along busy, congested highways and through towns and urban areas – with far greater potential for loss of human life and property.
A fiery 2013 derailment in Quebec killed 47 people and left many more badly burned; rail accidents in Colorado and Virginia resulted in significant oil spills but fortunately no deaths. By carrying 830,000 barrels of light and heavy crude every day, Keystone XL would eliminate the need for 1,225 railroad tanker cars per day (450,000 per year) or 3,500 semi-trailer tanker trucks daily (1,275,000 annually)!
More than 99.9% of oil moved by pipeline arrives safely at its destination, the Wall Street Journal notes. Rail transit is 2.5 times more likely to have an accident resulting in an oil spill, and trucks are six times more likely to do so – with both far more likely to injure, burn or kill many people. Indeed, the 5,000-barrel spill happened after the Keystone pipeline had safely delivered more than 1.5 billion barrels of oil, and TransCanada isolated the affected pipeline section within 15 minutes. No serious damage occurred.
Equally important, wind and solar substitutes for fossil fuels have their own major ecological impacts – which few environmentalists ever acknowledge. Using wind power to replace current US electricity generation and charge batteries for just seven windless days of backup power would require some 14 million towering 1.8-MW bird-and-bat-killing turbines, across acreage twice the size of California. The backup power would require over 650 million 100-kWh Tesla battery packs on still more acreage.
This does not consider what it would take to replace vehicles with electric versions – or coal and gas fuel in foundries, refineries and factories. The steel, copper, lithium, cobalt, rare earth elements, fiberglass and other raw materials to build all those turbines, batteries and transmission lines would require massive quantities of earth removal, mining, processing, smelting and manufacturing – much of it in developing countries under dangerous, inhuman conditions. Renewable energy is not ecological or sustainable.
Activists who cry Climate Armageddon attempt to tie every temperature rise, hurricane and other extreme weather event to human greenhouse gas emissions. They ignore the record 12-year drought in Category 3-5 hurricanes striking the U.S. mainland, prior to Harvey – and the “warming hiatus” that has prevailed since 1998, except during the 2015-16 El Niño temperature spike.
Climate computer models falsely assume that plant-fertilizing carbon dioxide drives climate change … and predict average global temperatures a full 1 degree F higher than have actually been observed by satellites and weather balloons, a gap that is widening every year. It now appears that Western Antarctic ice shelf instability is due to volcanic and magmatic activity beneath it – not climate change.
Heavily subsidized, sporadic, unreliable wind and solar combined provide less than 3% of all U.S. energy. One day, they (or some other as yet unimaginable energy source) may replace the fossil fuels that still account for 81% of the energy that makes US livelihoods, living standards and life spans possible – and is lifting billions out of abject poverty, malnutrition and disease. But that day has not yet arrived.
Fossil fuels provide feed stocks for paints, plastics, pharmaceuticals and other products that enrich and safeguard our lives. They keep our lights, heat and air conditioning on, and power the manufacturing centers that create computers, smart phones, healthcare technologies, vehicles and batteries. They take patients to hospitals, people to work and events, products to retailers and homes.
They are the most efficient, most affordable power source for the modern civilization which we Americans enjoy and take for granted – and to which all humans aspire. Pipelines are the fastest, safest, most direct, most economical way to get oil and natural gas supplies where they are needed.
Keystone XL is a vital addition to America’s pipeline system. It’s not perfect. But it is essential for a healthier, safer, more prosperous United States. Building it will create tens of thousands of jobs.
As to handling anarchists who think they are above the law, these suggestions may help. Ensure that there are sufficient police and National Guardsmen to maintain control. Require permits and multi-million-dollar surety bonds for every encampment, to ensure safety, lawful activities, and cleanup of human and other wastes. Prohibit wearing of ski masks and collect IDs, fingerprints and photos of every activist.
To prevent hypocrisy in anti-fossil fuel anarchist camps, prohibit all petroleum-based synthetic fibers (clothing, tents, sleeping bags); clothing derived from fibers grown, harvested and/or manufactured using fossil fuels; computers and cell phones with plastic housings; and transportation from protest sites in vehicles fueled or manufactured with hydrocarbons, in aircraft, or on asphalt roadways.
Allow only growing, harvesting, garment manufacturing, food, cooking and travel using all-natural pre-1900 technologies – so that campers can learn how wonderful life was back in the “good old days.”

It is time to reform the Renewable Fuel Standard
Can King Corn be defeated?
By Printus LeBlanc
Two political powerhouses are getting ready to do battle. Texas and Louisiana are the hub of U.S. energy production, and Iowa and Nebraska are the hub of U.S. ethanol production. The two groups are battling over a law passed over a decade ago that made one region of the country the king of subsidies. Those subsidies are now putting pressure on large swaths of the economy and must be addressed.
On Dec. 1, Texas Governor Greg Abbott sent a letter Environmental Protection Agency (EPA) Administrator Scott Pruitt requesting a waiver of the Renewable Fuel Standard (RFS) mandate for Texas.
First, a quick primer on the RFS. In 2005, the RFS was established under the guise of helping the environment with the passage of the Energy Independence and Security Act of 2007. The program requires fuel sold in the U.S. to contain a minimal amount of renewable fuels, the majority being corn ethanol. To track the renewable fuel, a Renewable Identification Number (RIN) is assigned to each batch of biofuel. The RINs count towards the Renewable Volume Obligation (RVO), an amount designated to each refinery by the EPA.
Seems somewhat simple, but there is a problem for exporters and refiners that do not have the ability to blend. The rule for a gallon of ethanol consumed in the U.S. is different for a gallon consumed outside the country. The rule states, “if a gallon of ethanol is produced in the U.S. but consumed outside of the U.S., the RIN associated with that gallon is not valid for RFS compliance purposes since the RFS program is intended to require a specific volume of renewable fuel to be consumed in the U.S.”
The rule forces exporters of ethanol and fuel blended with ethanol to lose the RIN credit. The refiner had to purchase the credit to make the fuel, now has to buy another credit to go towards the RVO. This is the point of Governor Abbott’s letter.
The RINs have now become Wall Street speculators’ weapon. Big banks are buying the credits from producers and hoarding them in dark markets, driving up the price. The increase in cost is being passed up the supply chain.
RINs are having a detrimental effect on refiners across the nation. Many are spending more on RINs than labor. The cost has already caused one refinery to close in Delaware and is threatening a closure in Pennsylvania.
The cost is also being passed up the supply chain. Alex Holcomb, professor of finance at The University of Texas-El Paso, studied the impact of high RINs prices on employment nationwide, finding that: “The RIN mandate, as its currently structured, puts refiners at higher risk of bankruptcy, placing at risk a significant number of jobs that are tied to the refinery sector both directly and indirectly. As is usually the case in bankruptcy, workers end up suffering the most acute economic hardship, especially if they are unable to quickly find comparable re-employment. From steelworkers to truckers, to the men and women earning minimum wage at their local gas station, an estimated 75,000 to 150,000 American jobs are potentially at risk if U.S. independent refiners go out of business.”
However, there is a middle ground everyone can agree on. Allowing RINs attached to exported biofuels to be counted towards the RVO benefits almost everyone:
The refiners no longer must pay twice for RINs;
The corn producers still produce the same amount of corn, and will have greater access to overseas markets;
Increases American exports;
There is one group the compromise does not benefit, Wall Street speculators. Since they did such a bang-up job with the housing market, no one is worried about them not profiting from a compromise.
It would behoove King Corn to pay attention. Yes, they are a potent political force, but several influential groups are drifting together to oppose them. More and more studies being done show the RFS does more harm than good to the environment. Environmentalists are starting to turn on the mandate. King Corn could soon be facing a united front of environmentalists (California, Oregon and Washington) and refiners (Texas, Pennsylvania and Louisiana), a lot more than the four Senators and seven House members in Iowa and Nebraska.
For over a decade the corn lobby has been getting billions in subsidies. It is time for them to allow the EPA to level the playing field for all in the fuel business. No one is trying to remove the mandate, yet. Iowa and Nebraska should get on board with reforming the RFS for the good of every American.
