Acknowledging that today's supercomputers lack the computational power to successfully model Earth's climate system, a climate modeler is suggesting that climate models would benefit from running on computers whose calculations are less exact. “In designing the next generation of supercomputers, we must embrace inexactness if that allows a more efficient use of energy and thereby increases the accuracy and reliability of our simulations,” says Tim Palmer, a Royal Society research professor of climate physics and co-director of the Oxford Martin Programme on Modelling and Predicting Climate at the University of Oxford, UK. This is nothing more than grasping for excuses to explain the dismal performance of the current crop of climate model simulations. There is an old saying: a craftsman never blames his tools for a bad result. Evidently climate modelers are not even close to being craftsmen.
A number of media outlets picked up a story recently about increasing swarms of giant mosquitoes endangering caribou and blotting out the Arctic Sun. Evidently this all came from a research report that stated the obvious, a longer, warmer summer would lead to a longer mosquito season in the Arctic. Having lived in Alaska, I can verify that the mosquitoes there are huge and their swarms can almost blot out the Sun, or at least it seems that way if you are getting bit. The problem here is that there is no evidence that there are more or larger mosquitoes emerging from the tundra of the north lands. This is yet another case of airhead news writers misunderstanding the facts or twisting them to fit their desired narrative.
For America this is a day for remembrances: we need to remember those who were so pointlessly and callously slaughtered on this date in 2001; we need to remember those brave first responders who rallied to save those they could, often giving up their own lives in the process; and we need to remember those who perpetrated this savage, cowardly attack on innocent men, women, and children without a thought to common decency. This single heinous act proved to America that true evil does exist in the world.
We have all heard about the Ice Age, if only in cartoon movies. A time when massive ice sheets covered the planet while mammoths and saber toothed cats roamed the frozen landscape. What is more, the cycle of interglacial-glacial-interglacial has happened over and over again during the past million or so years. During the last half a million years the cycle has repeated every 130,000 years, with the warm period we are now enjoying—the Holocene—just the latest interglacial respite from the icy conditions of the Pleistocene Ice Age. What most people don't know is that there were many areas on Earth that remained unchanged, even during the height of the last glacial period. The Sahara was hot and dry, and in the Amazon rainforests, though a bit smaller in area, looked much like they do today.
A lot has been written about melting ice caps and new mini-ice ages recently. Seems that science can't decide if we are going to drown in rising oceans or starve because summer will be a thing of the past. This leaves the layperson justifiably confused as to who to believe—the climate change alarmists who back rapid global warming or those who warn of a new glacial period. There is little certainty when it comes to science but one thing that can be counted on is our ignorance. Quite simply, scientists cannot predict with any certainty what Earth's climate will do next. If someone tries to tell you different they are lying.
The term “settled science” gets tossed around in the media a lot these days. Mostly by non-scientists, who know no better, and by some errant scientists, who should. In 2002, the U.S. National Research Council Committee on Abrupt Climate Change published its findings in a book entitled Abrupt Climate Change: Inevitable Surprises. A new report in Science recaps the surprising discoveries made since then, and they are big. So big that ocean circulation models, integral parts of all climate models, do not accurately predict reality. The observed change in AMOC strength was found to lie well outside the range of interannual variability predicted by coupled atmosphere-ocean climate models. Sounds like circulation in the Atlantic Ocean is not so settled.
The Triassic–Jurassic boundary 200 million years ago marked the beginning of the dinosaurs’ dominance of the entire planet. Following the worst ever extinction event at the end of the Permian, 252 mya, dinosaurs started showing up in the fossil record around 245 mya but did not spread to all areas of the globe until the end of the Triassic. A new study in the Proceedings of the National Academy of Sciences (PNAS) posits one possible explanation for why the spread of dinosaurs was stymied. Sadly, this interesting but not conclusive report was immediately seized upon by climate alarmists as a cautionary tale about atmospheric CO2 levels. A news item in Science online labels modern levels “alarming” and implies that a fiery fate, like the one that held the dinosaurs at bay for so long ago, awaits us all.
Climate alarmists are all atwitter over a new paper from researchers at NOAA/NCDC. In that paper the claim is made that the 18+ year pause in global warming is not real and that temperatures have been going up as expected. After more than a decade agonizing over the cause for the pause, desperately searching for the “missing” heat, dogmatic climate scientists have given up and simply declared the whole “hiatus” an accounting error. The temperature record in question is a kludged up global yearly average based on a hodgepodge of reporting stations, some on land and others at sea. In performing a “reanalysis” of the temperature record it was “discovered” that changes in the way temperatures were measured, particularly at sea, were systematically wrong, and “correcting” these readings causes the whole pesky pause thing to go away. What isn't mentioned are the other datasets that clearly show the pause is real, including two different satellite records. Has the climate catastrophe cabal given up all pretense of doing real science and decided to manipulate the data to give the answer they want? Many think so.
Climate scientists have constructed models to predict what Earth's climate will look like decades, even hundreds of years in the future. Unfortunately, many major components of Earth's climate system have not been accurately monitored for very long. This makes such predictions suspect if not laughable. A case in point are variations in ocean circulation and temperature. In the Atlantic there is a cycle for sea surface temperatures variation called the Atlantic Multidecadal Oscillation (AMO). The AMO is linked with decadal scale climate fluctuations like European summer precipitation, rainfall in Europe and India, Atlantic hurricanes and variations in global temperatures. A new study in the journal Nature reports that the AMO is again transitioning to a negative phase, meaning the vaunted “pause” in global warming may be with us for decades. In fact, scientists at the University of Southampton predict that cooling in the Atlantic Ocean could cool global temperatures a half a degree Celsius.
Germany is the economic powerhouse of the EU, with a far larger and more industrialized economy than other European nations—the fourth largest in the world. Given such a large industrial base it is unsurprising that Germany needs reliable power, which makes its headlong rush into renewable energy, called Energiewende (“energy transition”), even more mystifying than similar attempts by smaller EU states. Now come reports that the country’s rapid expansion into solar, wind, and other renewables has not been entirely smooth. Subsidies and regulations are promoting ill considered wind and solar installations while driving up costs. Slipped in among the solar panels and wind turbines are "biomass" generators—in other words, things that burn wood and agricultural waste—and the green party's anti-nuclear pogrom has led to an upsurge in coal usage. This hardly sounds like progress. Meanwhile, a new article makes bold claims for three of the smaller EU markets. Denmark, Portugal, and Spain have all made rapid transitions away from fossil fuels for electricity, but each in a different way. Are they truly examples for the world to follow?
Nitrous oxide (N2O) is a known greenhouse gas (GHG) that is more potent than CO2 and is a contributing factor in ozone layer depletion, yet little has been published on natural sources of this compound. Despite the importance of fungi in several soil functions, the production of N2O by fungi has only been studied in a limited number of strains. A new report in the journal Nature has revealed that may types of fungi naturally produce N2O. Obviously this is more of that “settled science” the climate alarmists forgot to mention.
Despite what gets reported in the news media, there are good climate scientists out there, quietly laboring away at that “settled science.” They are actually trying to understand climate instead of making unsubstantiated, bombastic predictions about future global warming. As a result, several recent papers have cast additional doubt on the validity of climate models as they now stand. In one, wide variation in solar radiation at the top of the atmosphere adds to the major errors in basic physics inherent in the so-called “state of the art” climate models. Another paper, on aerosol radiative forcing, casts doubt on the fundamental assertion of climate alarmists regarding the warming power of CO2. Adding to the stink over the settled science claim, the journal Nature carried a news article that says such assertions are “absolutely not true” and pleads for a new crop of physicists to help unravel the persistent ongoing climate mysteries. The outlook for climate science is cloudy indeed.
Recently, a PR offensive has been mounted by the minions of climate alarmism, attempting to rehabilitate the soiled reputation of climate models. Most everyone by now has heard of the 18+ year pause in global temperature increase, dubbed the “pause” by climate change advocates. This hiatus in global temperature increase, happening in the face of ever rising atmospheric CO2 levels, has caused even the most die hard climate alarmists to doubt the veracity of climate science's digital oracles. The latest phrase being test marketed in the green stooge press is the claim that climate models are just “Basic Physics”, implying that they are in some way scientifically accurate. Nothing could be farther from the truth.
As you may know, the current head of the UN Intergovernmental Panel on Climate Change (IPCC), Rajenda K. Pachauri has been forced to resign over sexual harassment allegations by women on his staff. Out on bail, Pachauri’s downward spiral continues: On March 1, Indian Prime Minister Narendra Modi accepted Pachauri’s resignation from the Prime Minister’s climate change council. Given this opening at the top of the world's premier climate change organization we think it time a real climate scientist heads the agency. Help us by signing the petition to President Obama today.
Proving the old adage, if your first lie isn't believed lie again and make it a whopper, NASA GISS announced another study proclaiming imminent climate catastrophe. This time it's the US Southwest and the scourge is not just drought, it's Megadrought! The report predicts that decades-long droughts are likely to ravage the US Southwest and Great Plains within the next century. “This drying could be worse than any other in the past 1,000 years, including a 'megadrought' seven centuries ago that helped drive an ancient civilization to collapse,” wails Nature online. But just how did the researchers come to this conclusion and what evidence do they base their predictions on? As it turns out the whole thing is a house of cards.
