640,000 Years Of Climate Change

A new study of the Asian Monsoon record has shed light on Earth's changing climate over the past six-hundred and forty millennia. Drawn from an exhaustive and painstaking examination of the relative proportions of the oxygen isotopes 16O and 18O in stalagmites, records from Chinese caves characterize changes in both the Asian monsoon and global climate. This record supports the idea that the 100,000-year glacial/interglacial cycle is an average of discrete numbers of precession cycles. Further more, changes in insolation, the amount of energy received from the Sun, triggers deglaciations and shorter term millennial events. No evidence supporting the upstart theory that CO2 controls climate change is reported.

Of Models And Melting Ice Caps

Once again climate scientists have put forth a scary prediction about melting ice caps and once again they are portraying output from computer models as a reliable prediction of things to come. The normally staid and reliable journal Nature emblazoned its cover with “Rising tide” in large black print, with the subtext “A 500-year model of Antarctica's contribution to future sea-level rise” in smaller print below. When a closer look is taken at this new model it turns out to be a house of cards, incomplete and built on top of other climate change models that are known to be faulty. As the old saying goes: garbage in, garbage out. Yet a major science journal chose this piece of computerized legerdemain as its lead article. No wonder that climate alarmists, and climate science in general, have fallen into such ill repute.

Glacial Inception Delayed By Humans?

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.

Patrick Moore: Should We Celebrate CO2?

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.

Figuring Out Ice Ages

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.

Burning Dinosaurs & CO2

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.

Fungi & Nitrous Oxide, The Forgotten Greenhouse Gas

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.

2014 - Annus Horribilus For Climate Alarmists

As the new year begins the forces of climate alarmism find themselves in disarray. The world refuses to warm, despite contorted data manipulation aimed at squeezing out a claimed “hottest year ever” record by NOAA. One hundredth of a degree does not a warming trend create. Northern hemisphere temperatures are depressed for the second year in a row—also not a climate trend in itself but a psychological blow to the warmists trying to sell the idea that temperatures are at a record high. Moreover, there are indications that the climatologists' bane, CO2, is not ravaging tropical forests and is not being produced where the “blame the developed world first” crowd expected. In all, a good start to the new year because it is a bad start for the alarmists.

Big Bang Blunder and the Carbon Pollution Canard

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.

The Tragedy Of Earth Day

It is Earth Day today, a chance for all tree huggers, green activists and other self absorbed eco-types to feel good about themselves by disparaging their neighbors. There was a time when environmental issues were rightfully at the top of people's concerns—the skies above our cities were brown and noxious, our rivers and streams poisoned with pollution, lead was accumulating in the environment and our children. The problem is, though most major problems have been addressed, the bureaucracy that was created to fix the environment cannot help but look for new problems that demand solutions, even if the problems are slight and the solutions draconian. Chief among these new problems is “carbon pollution” by which the eco-enforcers mean CO2 emissions. The tragedy of Earth Day is that governments spend billions of dollars on meaningless efforts to curb carbon dioxide while billions live in poverty and squaller around the world.

The Other Climate Report

On March 31, 2014 the fifth in a series of scholarly reports produced by the Nongovernmental International Panel on Climate Change (NIPCC), Climate Change Reconsidered II: Biological Impacts, was released to the public. While little reported in the main stream media, this new publication represents an independent, comprehensive, and authoritative report on the current state of climate science. It is an answer to the propaganda put out by the UN's Intergovernmental Panel on Climate Change (IPCC) and its lackeys and a direct refutation that no real climate scientists dispute the conclusions of the climate change alarmists. For those who do not accept the claims of consensus science or the fatuous assurances that global warming is an imminent threat by vacuous politicians, this report sheds light on the real science behind global warming and its possible effects.

Avoiding A Frozen Earth

Forty million years ago, Earth began slipping from a “hothouse” climate to an “icehouse” climate. Currently the planet is in a brief warm interlude know as an interglacial—a period of retreating ice sheets and shrinking glaciers. As the word interglacial suggests, our current comfortable climate is not permanent, but merely a pause between frigid ice age conditions. Though climate alarmists and media talking heads continue to natter on about uncontrollable rising temperatures a more devastating climate change would be a descent into an ice age so cold and so deep that the entire globe freezes over—it has happened before. A new scientific paper reveals what researchers say is a feedback mechanism that acts as a natural thermostat and keeps Earth from cooling to the point of uninhabitability.

Going Green With Rising CO2

While the debate rages regarding global warming and mankind's role in climate change there is one area that is not in dispute: the steady rise in atmospheric CO2 over the last century. Indeed, climate change alarmists celebrated CO2 readings passing 400ppm at Mauna Loa with news releases and renewed predictions of the coming Apocalypse. But carbon dioxide has other impacts, one of which has recently been documented by the Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia's national science agency. According to CSIRO, increased levels of CO2 have helped boost green foliage across the world’s arid regions over the past 30 years. This is because of a process called CO2 fertilization, which unequivocally shows that carbon dioxide is plant food.

Problems With The Pliocene

Climate alarmists are constantly warning that Earth is going to warm up, driven they say by the level of CO2 in the atmosphere. To bolster their claims they point to the Pliocene, a time 4-5 million years ago, when the planet was 4-8°C hotter and CO2 levels were 400ppm or higher. This is the climate we are heading for, the global warming supporters say—but it that really true? Superficially it seems a plausible assertion, but as it turns out there is much more here than CO2 and temperature. It is not just the average temperature but the distribution of temperature at different latitudes, both over land and sea, that controls the climate. It is the temperature gradient that drives storms and affects weather patterns and it was much different during the Pliocene. Moreover, climate models do not generate a Pliocene like climate when run with higher CO2 levels, which means climate scientists are missing something important about the way Earth's climate system works.

Forget Global Warming, The Ice Age Is Coming!

Scientists have long suspected that the orbital cycles of our planet are responsible for the periodic climate variation that causes alternating glacial and interglacial periods. Milankovitch's theory of orbital cycles suggests that summer insolation at high northern latitudes drives the glacial cycles. Moreover, statistical analyses have demonstrated that the glacial cycles are indeed linked to eccentricity, obliquity and precession. Now, researchers have confirmed that a combination of two of the Milankovitch cycles conspire to start and stop ice ages. The 100,000-year eccentricity cycle amplifies the influence of the 23,000-year wobble of Earth's spin axis called precession. The new modeling also suggests that the great accumulation of mass by the North American ice sheet causes the abrupt end of glacial periods. CO2 is involved, but is not determinative, in the evolution of the 100,000-year glacial cycles say the scientists.
