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.
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.
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.
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.
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.
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.
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.
Much has been done to vilify carbon dioxide in the media. Listening to the talking heads and on-air “experts” could lead one to believe that CO2 is an evil scourge that the world would be better off without. Nothing could be further than the truth. CO2 is necessary for life on Earth, forests in particular. It is not just plant food, the maligned gas also plays a role in regulating water use by the world's forests. New research has uncovered an unexpectedly strong decrease in H2O uptake caused by increasing CO2. Along with global increases in photosynthesis, forest growth rates, and carbon uptake, higher CO2 levels contribute to enhanced timber yields and improved water availability. Who says higher CO2 levels are a bad thing?
This must be the season to bash electric automobiles. Even the staid IEEE Spectrum featured an article questioning the ecological soundness of electric vehicles on its cover. But aren't electrics and hybrids supposed to be the way to a green future? Think again. Environmentalists' love affair with electric vehicles (EVs) seems to be over. “If you are thinking of buying an electric car for the sake of the environment, you may want to think longer.,” says Bill Sweet of IEEE's EnergyWise. “You’re not doing the planet as much of a favor as you might think.” Does this make all those Prius drivers officially posers? Or were they all just duped by a passing green fad, which, like all green fads, was based on faulty reasoning and the triumph of emotion over reality?
It has been vilified in the press and maligned in school classrooms by the ignorant. Opposing it has become a cause célèbre in Hollywood an a litmus test for liberal politicians. Labeled man's chosen weapon for ravaging nature and laying waste to the environment this poor, largely misunderstood gas is in fact essential to our existence. Without carbon dioxide, CO2, we would not be here and Earth would be a frozen lifeless chunk of rock. Forget that life would never have developed on a planet without greenhouse warming, a recent scientific study say the daemon gas has rescued the planet from the deep freeze at least twice during the Neoproterozoic era, roughly 750 to 635 million years ago.
Writing in a paper to appear in the journal Environmental Science & Technology, NASA scientist and noted climate alarmist James Hansen has come down on the side of nuclear power. He and coauthor Pushker A. Kharecha claim that getting power from nuclear energy actually saves lives. “Global nuclear power has prevented about 1.84 million air pollution-related deaths,” they report. Of course it also prevented 64 gigatonnes (Gt) CO2-equivalent greenhouse gas (GHG) emissions, when compared to the burning of fossil fuels, perhaps explaining why Hansen has suddenly become a nuclear power booster. With global warming on hiatus for the past decade and a half, the climate change cabal may be growing desperate for allies and have turned to that most unloved of energy sources—nuclear. Is this a sign that warmists and tree-huggers have a developing schism over nuclear power?
For decades the US government has funded research into “clean coal” technology. Billions of dollars have been spent with the only visible result being employment for a small army of government coal researchers and academics. Now scientists at Ohio State University have announced that, after 15 years of effort, they have produced a breakthrough—a new technology capable of turning coal green and carbon dioxide emission free. This was widely reported in the news media and passed practically without critical comment. Is it true? Is coal no longer the dirty, devil spawned fuel of evil industrialists everywhere?
Back in 2005, the IPCC Working Group III Special Report on Carbon Dioxide Capture and Storage declared that the storage of naturally and industrially produced carbon dioxide in depleted hydrocarbon reservoirs and aquifers was considered an essential component of the strategy to combat the build-up of greenhouses gases in the atmosphere. It seemed like an easy solution, pump CO2 captured from nasty coal power plants and other high volume greenhouse gas sources back into the underground reservoirs that oil and gas has been extracted from. After all, those geologic formations held hydrocarbons for millions of years—now the pumped out oil fields are just sitting there, waiting to be put to use. That was until testing was done on rock from actual cap strata. It would appear that infusing rock layers with CO2-saturated aqueous fluid can alter the properties of caprock, leading to the escape of the sequestered carbon back into the environment.
A newly released study from the Research Council of Norway has climate change alarmists abuzz. One of the things the alarmists have been pushing for is to halt warming at a 2°C increase at any cost (and they mean that literally). In the Norwegian study, much to the alarmists' dismay, researchers have arrived at an estimate of 1.9°C as the most likely level of future warming. The report also recognizes that temperatures have stabilized at 2000 levels for the past decade even though CO2 levels have continued to rise. Meanwhile, a reconstruction of the Eemian interglacial from the new NEEM ice core, published in the journal Nature, shows that in spite of a climate 8°C warmer than that of the past millennium, the ice in Northern Greenland was only a few hundred meters lower than its present level. This finding casts doubt on the projected melting of ice sheets and resulting sea-level rise.
