drought

Forests, CO2 and H2O

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?

Scientists Admit They Cannot Predict Drought

The threat of widespread and persistent drought, ruining crops and threatening water supplies, is constantly cited as an outcome of global warming. Media talking heads, climate scientists (who should know better) and even the American President have all made this assertion—and there is nothing to back up the claim. Results presented recently at the annual assembly of the European Geosciences Union in Vienna show that forecasting drought is still beyond the reach of current climate models. Models run against historical data have either predicted periods of drought at the wrong times or missed them all together. Yet climate alarmists continue to spread this pernicious lie, preaching damnation with the certitude of an Old Testament prophet.

Comforting Science For Earth Day

Since it was recently Earth Day, a yearly day of celebration and protest by conservationists and assorted greens, it is instructive to take a look at a number of recent studies taken from the scientific literature. The dire predictions made by climate change alarmists are many, far to numerous to all be addressed here, so this article will examine three areas of concern: increased drought, destruction of the world's rainforests, and the die-off of ocean coral reefs. Each of these reported calamities has been linked to increasing anthropogenic greenhouse gas emissions and that supposed bane of nature, anthropogenic global warming (AGW). These threats have been repeated ad nauseum by talking heads and climate change activists, but the truth is that these predicted outcomes are not as threatening as they would have you believe.

Ice Unknown

It's everywhere on Earth, on the other planets and moons of the solar system, and even in comets from deep space. It is the frozen form of water, commonly called ice. Something so ubiquitous and familiar, one would think that science knows a lot about ice. It turns out science knows less than we might suppose. In a commentary in the journal Nature, an ice scientist raises ten open questions about ice. For example, the article states: “We cannot predict with certainty when and where ice clouds will form in the atmosphere; areas of the sky remain humid when we would expect them to freeze.” Ice is a fundamental part of Earth's climate, yet these questions and others remain unanswered. How can climate science claim to predict the fate of the polar ice sheets or mountain glaciers when we do not really understand the substance that they are made of?

Climatologists Retrench As Climate Refuses To Warm

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.

IPCC Gets It Backwards, Drought Causes Warming

The Intergovernmental Panel on Climate Change (IPCC) has consistently predicted expanding world wide drought as one of the horrors of global warming. New research suggests that things may not be quite as arid as they predicted. According to scientists, a commonly used technique for estimating drought severity may actually overestimate the effects of dry spells. Revisiting historical data for the period 1980-2008, a new assessment technique found that the global area stricken by drought grew by approximately 0.08% per year—less than one-seventh (14%) the increase previously reported. Moreover, researchers found that drought causes higher temperatures, not the other way around. Once again, the horrendous effects of anthropogenic global warming have been found to be over hyped by the self-serving savants of the IPCC.

Scientifically Ignorant, Tabloid "Climatologists" Blame Sandy On Climate Change

In a mad rush to prove who can put out the most inane press release, various warm-mongers, news hacks and climate alarmists have gone on a predictable spree, trying to blame Hurricane Sandy and the resulting disaster in the US Northeast on CO2 levels. Who are these clowns? Even the IPCC issued a statement saying that global warming was not to blame. Have none of these empty headed blatherskites noticed that it has been more than seven years since a major hurricane struck the US, the longest such period since the Civil War? Evidently not, since they continue to spew unscientific twaddle and the news media continues to lap it up like a dog eating its own vomit.

America's Corn Hole

Most Americans have noticed that the price of gasoline at the pump has started to rise again. Gasoline prices have surged 30 cents since mid-July and now average $3.70 a gallon, higher than year-ago levels in 39 states. While some sources have blamed the recent refinery fire in California and others a rise in crude oil prices there is one hidden source of increasing fuel costs few are willing to mention—ethanol. Mandated by Congress to make up 10% of automotive gasoline, ethanol made from corn accounts for a quarter of recent fuel price increases while at the same time contributing to rising food costs and shortages world wide. Not satisfied with this astounding government largess, an unnatural alliance of eco-activists and big agribusiness is lobbying to raise the mandate to 15%. It is time for this blatant government kickback to end.

The Once & Future Climate?

Between 15 and 20 million years (Myr) ago, Earth's climate took a pause during its long slide into the Pleistocene Ice Age for a period of real global warming. During this relatively brief time glaciers around the world retreated and there are indications that, at least around the edges of the continent, there was significant vegetation on Antarctica. Temperatures may have been as high as 11°C higher than today. Scientists say this global warm spell took place under under CO2 levels in the range of 190–850 ppmv, both significantly higher and lower than today's 390 ppmv. It is hoped that studying conditions during the Miocene warming can provide constraints on the fundamental laws governing the climate system. Why? If the Pleistocene Ice Age is truly coming to an end, as some have said, this may be the climate of the future.

Desperate Climate Scientists Blame Bad Weather On Global Warming

After decades of debunking and statements by responsible scientists that climate is not weather and individual anomalies are not an indication of climate change, the government funded IPCC lackeys at the UK's Met Office and America's National Oceanic and Atmospheric Administration have publicly attributed recent bad weather events to man-made climate change. These irresponsible boffins' shrill claims illustrate the desperation in the anthropogenic global warming (AGW) camp in the face of declining public concern over climate change. While admitting that it is impossible to blame a single event on global warming, climate alarmists are claiming attribution is possible as long as it is framed in terms of probability. They have gone from lies, to damn lies and now, finally, to statistics.

Climate Science's Tangled Web

Recent days have seen a number of announcements about our changing climate. As it turns out Arctic ice is rebounding, sea levels are dropping and things just are not going according to the IPCC's plan for catastrophic global warming. Faced with reversal after reversal, it might seem logical for mainstream climate scientists to admit that they are wrong, that global warming is not taking place at a breakneck pace, but this has not happened. Instead, climate change apologists are weaving a tangled web of excuses—hot is cold, wet is dry, up is down. No matter what happens to the world we live in, the root cause according to the doomsayers is always the same: it's always global warming's fault.

The Kingdom Of Darkness

North America, after suffering through a lingering cold, wet spring, is now experiencing a bout of record setting summer heat. Once again, the sizzling summer temperatures are being blamed on global warming. The prophets of climate catastrophe claim to be exposing mankind's folly by shining the light of science on humanity's sins against nature. Perhaps it is time to recall the words of Thomas Hobbs who described the Kingdom of Darkness as “nothing else but a confederacy of deceivers that, to obtain dominion over men in this present world, endeavour, by dark and erroneous doctrines, to extinguish in them the light.” With sweltering weather as their cover, minions of the ecological Kingdom of Darkness are again on the march.

Precautionary Principle Power Grab

Precaution is now an established tenet of environmental governance, law, and public policy at the international, national and local levels. When it comes to pollution, toxic chemicals, genetically modified organisms, endangered species and climate change, the so called precautionary principle has become the guiding doctrine for timorous souls everywhere. But more than that, it is a codification of the idea that before anything new is allowed, it must be proven, beyond a shadow of a doubt, to cause no harm to anything in anyway, under any conditions, anywhere—period. It is “look before you leap” on steroids and a major legal weapon used by environmentalists and neo-Luddites everywhere to hamstring human progress. Raising angst to an art form, progress hating activists have managed to block needed energy and industrial expansion at a critical time in humanity's development.

The Climate Apocalypse Industry

For years climate alarmists have terrorized the public with frightening tales of impending disaster, a coming climate apocalypse. Because of global warming fertile croplands will become arid and barren while desert areas will experience torrential rain and uncontrollable flooding. Tropical rainforests will wither in the heat and polar ice will melt. Coastal areas and islands will disappear beneath the ocean and the world's great cities will huddle behind great seawalls to avoid the flood. Nature's furry will drive millions of refugees to migrate to less blighted lands, followed by plague, pestilence and war. Because of human hubris our civilization will collapse, as has happened so many times in the past. Or maybe not. A quiet revolution among anthropologists and archaeologists has overturned the scientific dogma surrounding failed ancient civilizations, with some lessons for those who currently preach climate catastrophe.

Messing with Mother Nature

Even though climate scientists have not been able to identify all of the factors involved in climate regulation, or even develop trustworthy values for the ones they do know about, some eco-activists are proposing that we actively try to alter Earth's climate. Schemes to purposefully alter the environment on a global scale are called geoengineering, and it has been proposed as a way to counter act anthropogenic global warming and its side effects. The two main geoengineering options are limiting incoming solar radiation, or modifying the carbon cycle. Two articles, one in the Proceedings of the National Academy of Science and another in Nature Geoscience, report that controlling climate through geoengineering would be difficult, if not impossible, and may do more harm than good. At a time when we cannot even predict how climate will change on its own, proposals to engineer climate change are best left as thought experiments.
