Playing the Uncertainty Card

There is little doubt that the political forces promoting climate change hysteria are under attack and in retreat around the world. It has also become obvious that little global consensus exists among climate scientists regarding how to regain the public's trust. There is, however, ample evidence that the climate change alarmists have not learned their lesson. At a recent conference held in Washington, D.C., an eminent climate policy expert urged that scientists and policy leaders embrace the persuasive power of uncertainty. If you cannot convince the public with the facts, frighten them into going along anyway seems to be the message. This is not science, it is subterfuge justified by blind faith.

Scientists Link Quiet Sun & Cold Winters

Asking the somewhat obvious question, “are cold winters in Europe associated with low solar activity?” a group of scientists have announced that the answer is yes. While this may seem unsurprising, the finding is another indication that Earth's climate is not simply driven by greenhouse gas emissions. Even so, some scientists are only grudgingly accepting the finding, cautioning that this only applies in the central UK and refusing to admit that the Sun could affect global mean temperatures as well. Still, the researchers found that average solar activity has declined rapidly since 1985 and cosmogenic isotopes suggest a possible return to Maunder minimum conditions within the next 50 years. This could be a sign that climate science is starting to recover from its CO2 fixation.

Iceland's Ash Cloud May Let Climate Alarmists Off Hook

March 20, the Eyjafjallajökull volcano began erupting after slumbering for almost 190 years. The eruption also brought a threat of floods and earthquakes, while the resulting plume of volcanic ash shutdown the European airline industry, costing an estimated $200 million a day. In the short-term, the volcano has been bad for Northern Europe and given a boost to Iceland's tourist industry, but there are larger questions involved. With tedious predictability, a number of climate change alarmists quickly claimed that the volcano was caused by global warming. A more likely outcome is a cool Northern Hemisphere summer caused by airborne ash—which could give the alarmists an excuse for the continued lack of global temperature rise.

Why Climate Models Lie

It has come to light that a number of climate scientists have been less than truthful with regard to climate data. As shocking and embarrassing as this has been to the scientific community, it serves only to emphasize the huge blind spot that scientists have for their computer models. It is a career ending offense to knowingly falsify data, yet the entire climate science community engages in even worse deception without a second thought. This is because lies are generated for them wholesale by their faithful yet duplicitous servants: computer climate models.

Snowballs, Ice Ages and CO2

Earth's climate history includes numerous incidents of rapid warming and cooling. While Pleistocene ice-age glacial terminations are arguably the most dramatic recent examples of sudden climate change, during the last glacial period the climate of the Northern Hemisphere experienced several other significant episodes when the climate rapidly warmed. Scientists call these episodes Dansgaard-Oeschger (DO) events after the Danish and Swiss researchers who documented them using ice-core studies. These rapid oscillations are marked by rapid warming, followed by slower cooling. The most prominent coolings are associated with massive iceberg discharge into the North Atlantic Ocean known as Heinrich events (HE). The melting icebergs add large volumes of cold fresh water to the ocean, disrupting circulation patterns and causing further climate changes. Scientists look to past events like these to help us understand how Earth's climate system functions—what causes our planet to cool or suddenly warm. Recently, new data on past climate changes have led one commentator to predict the end of winter skiing in the American Southwest.

When Humans Almost Went Extinct

Around 1.2 million years ago, only 18,500 early humans were breeding on the planet. According to researchers, this is evidence that there was a real risk of extinction for our early ancestors. What's more, according to a new study it took at least a million years for humans to come back from the brink. It was not until the emergence of modern humans, Homo sapiens, around 160,000 years ago and their migration out of Africa that humanity's place on Earth was secured. Two factors helped humans to survive: an increasingly carnivorous diet and mastery of fire.

Why I Am A Global Warming Skeptic

The debate over anthropogenic global warming—a theory propounded by the UN IPCC—is often portrayed as an argument between deniers and true believers. The deniers supposedly claim that there is no global warming, man made or otherwise, and that the whole theory is a plot by left-wing agitators and closet socialists bent on world domination. The true believers, conversely, accept every claim of pending future disaster uttered by scientists and activists alike. As with most controversies both extreme positions are wrong and the truth lies somewhere in-between. As a scientist, I have studied the evidence and find the case for imminent, dangerous, human caused global warming unconvincing—here is why I am an AGW skeptic.

Geoengineering Gone Wild

A 2009 editorial in the journal Nature Geoscience, opined that, if participants at the Copenhagen Climate Conference failed to map out a path for future greenhouse-gas emissions that is both effective and feasible, then humanity might have to consider turning to “geoengineering.” Geoengineering, a term unfamiliar to most, is the deliberate manipulation of Earth's climate system to control global warming. Since Copenhagen was a resounding flop, new geoengineering proposals have been springing up in a number of scientific journals. Science is still struggling to understand how climate works and what accidental impacts human activities have on that system. Now a number of “visionaries” want to mess with the planet on purpose—what could possibly go wrong with that?

The Crumbling Pillars of Climate Change

One well accepted definition of the “Three Pillars of Science” lists the three as theory, experimentation and computation. For climate science this translates into climate theory, gathering climate data, and climate modeling. The three pillars are due an update in this post Copenhagen, post Climategate world. After reviewing the past year's crop of discoveries and disclosures, it seems that all three pillars are still wobbly at best—even without questionable conduct on the part of warm-mongering researchers.

Draining Swamps To Fuel Autos

A report out from the United Nations Framework Convention on Climate Change meeting, which was held in Barcelona, identifies peaty wetlands as a major source of CO2. Marshes, swamps and bogs emit about 1.3 billion tonnes of CO2 a year as a result of human activity that drains them. If those dried out former swamps catch fire that amount can double and large amounts of aerosols can be emitted as well. With governments offering subsidies for growing biofuel crops the question is, how do we stop people from draining the world's remaining wetlands?

Global Warming Fatigue Spreads

In the run up to Copenhagen, global warming alarmists are spreading the word that climate change is progressing even faster than the IPCC has projected. But contradictory data from skeptics and open minded scientists continues to indicate that global warming has gone on hiatus and may not return for decades. This has sparked a noticeable drop in public concern over climate change and has led some climate change true believers to bemoan increasing public “Climate Fatigue.”

Global Warming Predictions Invalidated

A new study in the journal Science has just shown that all of the climate modeling results of the past are erroneous. The IPCC's modeling cronies have just been told that the figures used for greenhouse gas forcings are incorrect, meaning none of the model results from prior IPCC reports can be considered valid. What has caused climate scientists' assumptions to go awry? Short lived aerosol particles in the atmosphere changing how greenhouse gases react in previously unsuspected ways. The result is another devastating blow to the climate catastrophists' computer generated apocalyptic fantasies.

Ice Age Terminations: Orbital Cycles, Ocean Circulation and Shifting Monsoons

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.

More Water Vapor Woes For Climate Modelers

Using satellite infrared spectroscopy to provide an almost global perspective on the near-surface distribution of water vapor, a new report in Science has identified more water vapor inaccuracies in current general circulation models (GCM), the computer programs used by climate scientists to predict future climate trends. The researchers uncovered anomalies in the Hadley circulation and its misrepresentation in GCM. Looks like climate theory and the IPCC's error ridden models are in for another round of corrections.

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.
