Mixed in with the swirling cloud of misinformation about global warming is also a bit of blather regarding the onset of a new Ice Age. What the promoters of a new big freeze are talking about is a glacial period, since technically we are still in the midst of an ice age—the Pleistocene. A number of scientists have warned that the planet might be headed for a new period of glacial growth based on Earth's recent history. Over the past half million or so years there has been a series of short (15-20k year) warm period sandwiched between longer (70-100k year) glacial episodes. Make no mistake, global cooling is much worse than global warming, so this really matters to our descendants and the whole human race. Now, a new study in Nature says that we maybe off the hook, glacial wise. Not only that, human activity might be the reason.
On October 14, 2015, Dr Patrick Moore delivered the Global Warming Policy Foundation annual lecture in London. An ecologist and environmentalist for more than 45 years, Moore was one of the founding members and a leader of Greenpeace. After 15 years he left the organization because he felt its mission and message had changed. “Over the years the 'peace' in Greenpeace was gradually lost and my organization, along with much of the environmental movement, drifted into a belief that humans are the enemies of the earth.” Since then, Dr. Moore has been a consistent voice for sanity in ecological matters. In his address he asserts that CO2 is not evil rather it is the currency of life and the most important building block for all life on Earth. Human emissions of carbon dioxide have helped save plant life on our planet. “We are not the enemy of nature but its salvation,” he proclaimed.
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.
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.
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.
The Rightful Place of Science: Disasters & Climate Change is the latest book by Roger Pielke, Jr., noted political scientist and professor in the Environmental Studies Program and a Fellow of the Cooperative Institute for Research in Environmental Sciences (CIRES). In it he addresses the controversial subject of whether natural disasters are becoming more frequent and more fearsome due to manmade climate change. This short volume is an excellent summary of his work in this area and a reference that anyone serious about climate change should have on their shelf. After receiving an advance copy of the work, here is my review.
To honor the overly excitable greens and mental dullards participating in this weekend's People's Climate March, we are going to give away The Resilient Earth ebook for Kindle. That's right, instead of spending a lot of time and effort (not to mention emitting a lot of CO2) you can stay in the comfort of your own home and read about the real science behind climate change. You can purchase your own copy of this science classic for absolutely nothing between 9/20/2014 and 9/22/2014. This entertaining, easy to read book contains color illustrations and hundreds of references, all of which will give you the facts regarding climate science and the global warming scare.
Marine and terrestrial proxy records suggest that there was a peak in global warming between 10,000 and 6,000 years ago, following the end of the last glacial period. Since the Holocene Thermal Maximum, Earth has undergone global cooling. The physical mechanism responsible for this global cooling has remained unknown and doesn't fit in with the current CO2 based climate models. Those climate models generate a robust global annual mean warming throughout the Holocene, mainly in response to rising CO2 levels and albedo changes due to retreating of ice sheets. In other words, the models disagree with reality, and when models disagree with nature the models have a credibility gap. A new paper in the Proceedings of the National Academy of Sciences (PNAS) says this model-data inconsistency indicates a critical reexamination of both proxy data and models is called for.
One of the sad side effects of the global warming climate scam is the way otherwise fairly intelligent people have been snookered into believing the dumbest things. An example in point: in a world where millions die each year due to malnutrition, US Secretary John Kerry lectured African leaders attending a summit in Washington that creating more farms in Africa causes too much carbon pollution. Can you imagine the response of any national leader, being told he must let his people starve because a bunch of rich nation, ivory tower science boffins have this unproven, wild idea that CO2 might cause the world to warm by a degree or two a hundred years from now? This is the type of imbecility that comes from following a pernicious untruth down a rabbit hole of false assumptions. Yet around the globe people seem defenseless against the infectious ignorance that is climate alarmism.
In 2013 a group of climate researchers published a study using statistics and the output of the latest crop of climate models. Their purpose was to show when surface temperatures could be expected to permanently depart from previous historical ranges. Such an event is called an expulsion. Camilo Mora et al. presented precise projections for when these unprecedented regional climates would emerge. Now a second group of researchers argue that their methodology produces artificially early dates at which specific regions will permanently experience unprecedented climates and artificially low uncertainty in those dates everywhere. This is an example of what happens when untrustworthy model outputs are combined with specious statistical methods. The resulting predictions are scary enough to be published in a major journal, but so false that even other climate scientists are moved to protest.
One of the greatest failures of climate science has been the dismal performance of general circulation models (GCM) to accurately predict Earth's future climate. For more than three decades huge predictive models, run on the biggest supercomputers available, have labored mighty and turned out garbage. Their most obvious failure was missing the now almost eighteen year “hiatus,” the pause in temperature rise that has confounded climate alarmists and serious scientists alike. So poor has been the models' performance that some climate scientists are calling for them to be torn down and built anew, this time using different principles. They want to adopt stochastic methods—so called Monte Carlo simulations based on probabilities and randomness—in place of today’s physics based models.
Hoards of non-scientists have been making a career out of pushing “settled science,” particularly when it come to climate change, the eco-socialists' favorite excuse for dismantling the world's existing economic and industrial base. Unlike the notoriously squishy science of climate change, physics is viewed as being mature and on a more solid foundation, at least by those who are physicists. Given the recent furor caused by the IPCC and NCA reports, plus the US EPA's ham handed attempt to institute CO2 Cap & Trade without the agreement of Congress, it is instructional for scientific outsiders to review recent events in both fields. Read on, believers in the myth of settled science and those who think scientific questions are resolved by consensus.
