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.
A few months back, the climate charlatans at the National Oceanographic and Atmospheric Administration (NOAA) made headlines by declaring the 18+ year pause in global warming a hoax, or at least a misunderstanding. In June 2015, NOAA scientists published an online article in the journal Science finds that the rate of global warming during the last 15 years has been as fast as or faster than that seen during the latter half of the 20th Century. Their study claimed to refute the notion that there has been a slowdown or “hiatus” in the rate of global warming. Climate change alarmists were ecstatic, the Pause was dead, long live global warming! Now, showing how settled the science behind climate change really is, a new paper in Nature Climate refutes the refutation. In a warmist's nightmare zombie Apocalypse, the Pause is back and NOAA stands revealed as the data fudging climate change activists they are.
In the year 536 AD the sun dimmed, and the gloom lasted for more than an entire year. There were frosts and snows in the middle of summer and observers reported that winter never really ended. The sudden shift in climate lead to famine, plague and the fall of empires. What was worse, that year was only the beginning of a shift in climate that brought misery to the entire Northern Hemisphere for more than a century. Yet this well documented period of global cooling was smoothed away by climate change alarmists in works of fabricated data like the infamous “hockey stick” tree ring history. A new analysis has rediscovered this dark period in recent human history, fittingly made possible by new tree-ring measurements from the Altai mountains in Russia. The results help complete a climatological history stretching back 2,500 years. Climate history is a pesky thing, it just won't go away and can't be changed to fit some scientists pet theories.
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.
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 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 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.
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.
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.
Back at the beginning of Earth's existence there was a time known as the Hadean Eon—Hadean as in Hades, or hell. The history of the Hadean Earth (~4.0–4.5 billion years ago) is poorly understood because rocks from that time have not survived. The oldest known rocks are little older than ~3.8 billion years. A new paper in the journal Nature attempts to shed some new light on the least known part of Earth's distant past. Researchers have long speculated about the conditions on Earth in the first 500 million years after the planet's formation, some 4.5 billion years ago. The researchers report that, according to their model, the early Earth is likely to have been hit by up to four asteroids, each capable of snuffing out fledgling life and completely resurfacing the planet.
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.
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.
