Skeptical Thoughts on Energy, Science and Global Warming

Crank of the Week - September 21, 2009 - Gisele Bündchen

In an effort to revive the rapidly fading global warming climate scam, the UN has enlisted fossil fuel-guzzling supermodel Gisele Bündchen to lead the counter attack. Ms. Bündchen has been named an official UN Environmental Ambassador by the United Nations Environment Programme (UNEP), one of the parent organizations of the infamous IPCC.

Climate Models Blown Away By Water Vapor

Contrary to what is said in the popular media, water (H2O) is the most important greenhouse gas in Earth's atmosphere, not the small amount of demonized CO2. But aside from acting as a greenhouse gas, water vapor plays an active role in shaping global atmospheric circulation and thus Earth's climate. Water does this by undergoing state changes—from liquid to vapor and back again—allowing water vapor to carry significant amounts of latent heat from the warm equatorial regions toward the poles. The importance of this heat transfer mechanism in climate regulation is poorly understood but new data have begun to show the impact is major. One thing is certain, most widely used climate models do not correctly account for the complex dynamics of water vapor.

Atmospheric Solar Heat Amplifier Discovered

For decades, the supporters of CO2 driven global warming have discounted changes in solar irradiance as far too small to cause significant climate change. Though the Sun's output varies by less than a tenth of a percent in magnitude during its 11-year sunspot cycle, that small variation produces changes in sea surface temperatures two or three times as large as it should. A new study in Science demonstrates how two previously known mechanisms acting together amplify the Sun's impact in an unsuspected way. Not surprisingly, the new discovery is getting a cool reception from the CO2 climate change clique.

Judging Global Warming As A Scientific Theory

The supporters of anthropogenic global warming (AGW) claim that they have science on their side. Time and again we are told that the debate is over, the science is settled and consensus among the world's scientists reached. If that is true, why are so many scientists coming forward to oppose and denounce the climate alarmist's theory? To understand the true nature of the climate change debate it is necessary to understand what a scientific theory is and how to judge a theory's validity.

The Grand View: 4 Billion Years Of Climate Change

Two of the terms bandied about by global warming alarmists are “unprecedented” and “irreversible.” It is troubling that scientists, who should know better, persist in using these terms even though the history of our planet clearly shows that neither term is accurate. Proof of this inaccuracy is obvious if we look back over the history of Earth—the Phanerozoic Eon in particular—taking the “Grand View” of historical climate change.

Humanity Blamed for 9,000 Years of Global Warming

Not satisfied with blaming modern civilization for causing rampant climate change, now a small group of scientists are saying that everything went wrong once humans stopped being hunter-gatherers 9,000 years ago. The hypothesis, first advanced in 2003 by University of Virginia palaeoclimatologist William F. Ruddiman, remains controversial even among global warming true believers. Ruddiman now claims to have proven his critics wrong, much to the glee of the blame-humanity-first wing of the eco-activist community.

Crank of the Week - August 24, 2009 - Nathan Rees

This week we have a nomination from down under. Premier Nathan Rees, head of the Australian state of New South Wales, has been nominated by his own constituents as our Crank of the Week. After reviewing Rees' qualifications we are in full agreement—anyone who can stand up at a scientific conference and compared climate change skeptics to Nazi appeasers certainly is a crank.

Confirmed! Orbital Cycles Control Ice Ages

While the IPCC and global warming alarmists continue to claim climate change is controlled by atmospheric CO2 levels, most knowledgeable scientists will tell you that climate change is caused by variation in Earth's orbit and orientation. These periodic changes in movement and attitude are called the Milankovitch Cycles. A new paper, to be published in Science, confirms that glacial terminations are caused by Earth's orbital cycles, not carbon dioxide.

African Dust The New CO2?

Chad, located along the southern edge of the Sahara Desert, is the dustiest place on Earth. Recognizing that aerosols plays a vital role in climate and biophysical feedback in Earth's environmental system, climate researchers are turning to dust as a major driver of climate change. A new article, to be published in PNAS, identifies the Bodélé Depression in Chad as the producer of about half the mineral aerosols emitted from the Sahara. According to Richard Washington et al. dust could be a “tipping element” where “small features of the atmospheric circulation, such as the Bodélé Low-Level Jet, could profoundly alter the behavior of this feature.” With the impact of CO2 diminished due to a cooling climate climate, researchers are searching for new hazards: Is African dust the new carbon dioxide?

Resilient Earth Authors Attend Scientists For Truth Conference

Al Simmons and Doug Hoffman attended the “Scientists for Truth” conference in Springfield, Mo, on August 13, and report that the affair was a complete success. The conference's mission was to raise awareness in America's heartland regarding the pernicious lies spread by climate change extremists and how dangerous the global warming hoax is to the country. Several hundred attendees, including a class of high school students, stood for a rousing rendition of the national anthem to kickoff a day of presentations by a full slate of prominent global warming skeptics.

The Sun, Not CO2, Caused Ice Age Glaciers To Melt

Increased insolation 20,000 years ago caused deglaciation in the Northern Hemisphere, according to a new report in the August 7, 2009, edition of Science. Further more, it was the onset of deglaciation of the West Antarctic Ice Sheet, which occurred between 14 - 15 thousand years ago, that was the source of sea-level rise at the beginning of the Holocene warming. Such events are often associated with rising CO2 levels by climate catastrophists but the evidence says otherwise.

Bleached Coral Reefs Bounce Back

Bleached and dying coral reefs are often held up as proof that global warming is laying waste to Earth's ecosystems. Now come reports that a number of reefs around the world are being brought back from the dead by dedicated oceanographers and conservationists. “The results are more than just promising; they are beautiful,” says Baruch Rinkevich, a marine biologist at the National Institute of Oceanography in Haifa, Israel. But how can these reefs recover in the face on ongoing global warming? Either global warming has reversed course or the bleaching of reefs wasn't due to global warming in the first place.

Shrinking Sheep, Kidney Stones and Bear Attacks

We have all heard the litany of woes about to befall mankind due to global warming: failing crops, spreading deserts, increased storm activity, rampant disease, and so forth. But these are not the most frightening side effects of global warming. Indeed, the IPCC's list only scratches the surface of the prophecies of doom and despair. Among the predicted results of a warming climate are smaller livestock, an increase in kidney stones, more frequent bear attacks and a host of other maladies and misfortunes.

Crank of the Week - July 27, 2009 - The International Council for Science

We have all become familiar with the sloppy, bureaucracy driven science promulgated by the UN IPCC. Now a another organization, the International Council for Science (ICSU), is vying for leadership in ruining free scientific inquiry world wide. “Natural sciences should no longer dictate the Earth system research agenda,” proclaimed their manifesto, which appeared in the July 17, 2009, issue of Science. “Social sciences will be at least as important in its next phase.”

Cloud Study Claims Unsuspected Positive Feedback

In a stunning paper in Science, researchers claim to have reversed the impact of clouds on global climate. It has long been known that low level cloud cover creates a net cooling effect on climate. This new study, which concentrated on a restricted area of the Pacific Ocean, claims that warming oceans reduce low cloud cover letting in more sunlight that further warm the ocean and hence provide a positive feed back that adds to global warming. Based on a warming episode that started in 1978, the article claims that observational analysis showed that clouds act as a positive feedback in this region on decadal time scales. But a cometary on the article in the same issue of Science says that the analysis suggests—but falls short of proving—that clouds are strongly amplifying the warming. If it's true, then almost all climate models have got it wrong.
