Another trip around the Sun and the resilient Earth endures, as it has for the past 4.5 billion years. We here at The Resilient Earth would like to wish everyone on the planet and especially our loyal readers a very Happy New Year, 2010.
While climate skeptics have gleefully pointed to the past decade's lack of temperature rise as proof that global warming is not happening as predicted, climate change activists have claimed that this is just “cherry picking” the data. They point to their complex and error prone general circulation models that, after significant re-factoring, are now predicting a stretch of stable temperatures followed by a resurgent global warming onslaught. In a recent paper, a new type of model, based on a test for structural breaks in surface temperature time series, is used to investigate two common claims about global warming. This statistical model predicts no temperature rise until 2050 but the more interesting prediction is what happens between 2050 and 2100.
The Oklo uranium mine in Gabon contains well known evidence of natural nuclear reactors, but how widespread were they? A team of researchers has proposed a scenario to account for the disappearance of a radioactive mineral from the geological record. Part of their hypothesis is that a surge of oxygen billions of years ago caused the creation of millions of tiny nuclear reactors. If true, this primordial nuclear age could have played a role in the evolution of early life forms.
A new book, entitled Data Engineering: Mining, Information and Intelligence, has just been published by Springer as part of the International Series in Operations Research & Management Science. Dr. Doug L. Hoffman was lead author on the Performance Modeling of Enterprise Grid Systems chapter of the newly published text book. The work is aimed at academics, students and industrial researchers in computer science and information systems.
One of the things that has been obscured by all the hand wringing and arm waiving about global warming is the existence of a threat to our planet that is very real and could arise suddenly. That threat is from non-planetary bodies within the solar system: asteroids, comets and other celestial wanderers. While the world's politicians and tree-hugging blowhards rail about the damage climate change might cause, a symposium was held in San Francisco to address a problem that actually could end life on Earth.
A new study has confirmed the astronomical theory of the ice ages, but with a new twist: The shutoff of the meridional ocean circulation, or MOC, and an associated southward shift of tropical monsoon rain belts seems to play an integral role in the melting of glacial period ice sheets. These changes cause warming of the Southern Hemisphere and a rise in atmospheric CO2 levels, which in turn provides a positive feedback loop that helps drive glacial termination. This is why, every 100,000 years or so, the great Northern Hemisphere ice sheets collapse and glacial conditions give way to a warm interglacial period, such as the Holocene warming humanity is currently enjoying. This, however, does not support recent claims that global warming is causing the Southeast Asian monsoon to fail.
The search for ways to reduce carbon emissions has led to government grant money for schemes ranging from promising to wacky. Recognizing that there is no currently viable replacement for fossil fuels, with the possible exception of nuclear power, the US and other countries with large coal deposits are desperately looking for ways to continue burning coal without incurring the wrath of nature or the IPCC. Clear evidence of the seriousness of this effort is evident in this week's special edition of Science, dedicated to carbon capture and sequestration (CCS) technology.
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.
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.
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.
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.
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.
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.
In a five-part video series featuring Danish scientist Henrik Svensmark, the author of The Chilling Stars talks about his research into the effects that cosmic rays have on cloud formation. His theories contradict the IPCC’s theory of anthropogenic global warming, which basically blames last century's rise in average global temperature on human CO2 emissions. As many good scientists outside of the inbred climate change community have noticed, carbon dioxide just isn't up to the job of causing last century's observed global temperature rise. Instead, Svensmark and his colleagues hypothesize that clouds created by cosmic rays, which are in part controlled by the activity of the sun, regulate Earth's climate. Because this contradicts the IPCC's view of global warming, Svensmark's theory has been ignored by the climate alarmists and Svensmark himself vilified.
