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.
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.
The science is settled, the President of the United States assures us. His pet scientists have produced yet another frightening climate report to prove it. Given this President's tenuous relationship with the truth on other matters, a citizen might pause to ask if the claim of settled science is, in fact, true. In the recent past scientific papers have discovered some “unexpected” phenomena that help to regulate climate. In fact, one of the climate change faithful proposed a mechanism affecting the jet stream that could be responsible for this winter's unexpected weather in the northern hemisphere. Only problem, a number of climate alarmist luminaries have dissented from her idea. Remember the consensus that was supposed to shut down all opposing opinions? Never mind. Another study shows statistically that there is no way to establish a human caused warming trend without another 100 years of observation. Of course, if you believe the climate catastrophists the world as we know it will have vanished by then. So is climate science really settled? Here are just some of the most recent indications that it is not.
The state of Arkansas, in the south central portion of the United States, was struck last night by a number of storms that spawned deadly and destructive tornadoes. One of these tornadoes was a half mile wide at its base and reportedly stayed on the ground for eighty miles. The towns of Mayflower and Vilonia were particularly hard hit and the death toll currently stands at 16. Emergency officials and rescue crews are still searching for survivors. In the face of such a natural calamity people ask questions such as “could we have been more prepared” and “how can we help the victims.” Equally predictable in these times, a number of green pinheads have implied that this natural disaster was caused by global warming, and that we only have ourselves to blame. This is simply not true.
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.
As this blog has previously noted, the mainstream media are all a twitter over the IPCC's latest screed, advising, no, demanding that governments around the world take decisive action to combat that mythical bugaboo, anthropogenic global warming. Their own supporters, including President Obama and Secretary of State John Kerry, have been generating a lot of hot air about AGW but doing precious little, mainly because cooler heads in Congress have prevailed. What hasn't been widely presented are the counter arguments. The Nongovernmental International Panel on Climate Change (NIPCC), has issued its own report, Climate Change Reconsidered II: Biological Impacts, to counter the half truths and outright lies in the IPCC propaganda piece but it seems that information about the report has been suppressed. As a public service we proudly present an op-ed by Dr. Craig Idso, lead editor and scientist for the NIPCC.
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.
Supporters of the CO2 driven theory of anthropogenic global warming (CAGW) are in full panic mode. The continued hiatus in global temperature increase has led to a flurry of statements denying “the pause,” as climate scientists have named it. This new denialism even extends to international organizations like the WHO, that just recently claimed that global warming had not ceased, even though numerous organizations—including Britain’s Meteorological Office, NASA, and the IPCC—have admitted that it has. Among climate change true believers there is a scramble on to “find the missing heat” that would explain the pause. Strangely, among these practitioners of group think there is no consensus about the cause of the pause. At the same time, the IPCC is about to release its latest screed regarding climate change and the leaks have been flowing fast and furious, saying there is dissent in the land of consensus. This may well be the turning of the tide on the greatest scientific hoax in history.

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.
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.
Over 4,000 years ago, the Harappan Civilization of the Indus Valley faded and disappeared. Never heard of the Harappans? Theirs was a Bronze-Age civilization located where Pakistan and northwest India are today. With large, well-planned cities, municipal sewage systems and writing that has never been deciphered, they had a civilization equal to Egypt, Mesopotamia, and Greece. But the Harappans fell victim to what most view as a modern horror—climate change. Sometime around 2,100 BC the monsoon cycle, vital to all of South Asia, faltered. The reliable rains stopped, and man's earliest civilizations fell. Now we are told that California—that progressive paradise on the Pacific—is poised on the brink of its own drought spawned disaster. So desperate have things become that one restaurant chain has threatened to stop serving guacamole and vintners are turning to witchcraft. Can the total collapse of Californian civilization be far behind?
One of the scary scenarios frequently trotted out by climate change alarmists is the possible shutdown of the ocean currents in the Atlantic Ocean. This would disrupt northern hemisphere climate, particularly in Europe. Indeed, one Hollywood disaster movie had frozen military helicopters falling from the skies in the UK and Manhattan buried under a tsunami of ice. We are told this could happen at any time, if the world gets too hot from all that CO2 our species is churning out. Now a shocking new paper in the journal Science implies that the standard view of a relatively stable interglacial circulation may not hold for conditions warmer/fresher than at present. Why? Because it happened before, over 100,000 years ago, without the help of man made global warming. Another catastrophic climate threat is shown to be totally natural and to have happened before our species began burning coal and driving SUVs.
