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.

General Circulation Models (GCM), which simulate the physics and chemistry of Earth's land, oceans and atmosphere, are an essential component of the pseudoscience behind the global warming scam. Using large, complex computer programs doing indecipherable things while burning up exa-cycles of supercomputer time allows climate scientists to lay down a fake science smokescreen few can penetrate. Naturally, other scientists, with lower funding, are envious of climate modelers and their play toys, including ecologists. In an impassioned plea published in Nature, a group of environmental scientists argue that it is high time that they get to build models of their own. General Ecosystem Models (GEMs) could radically improve understanding of the biosphere and inform policy decisions about biodiversity and conservation they claim. But are they really aware of what they are asking for?

A new study in the Proceedings of the National Academy of Sciences (Early Edition on-line), is shaking up science's view of polar bear evolution. Previously, it had been suggested that the white bear of the north was a relatively young species that diverged from brown bears during the last glacial period. That glaciation started after the Eemian epoch (~125,000 years ago), peaking around 25,000 years ago. New genetic analysis pushes that estimated divergence back to 4-5 million years ago, though there seems to have been a significant level of interbreeding between the two species over time. Another important finding is that the polar bear population underwent a significant contraction around 500,000 years ago. According to this new information the polar bear has been around for much longer than previously thought, implying that it has survived many interglacial warm periods. In other words, those who think the polar bear cannot survive the shrinking of Arctic ice packs are dead wrong.

In 2009, the International Commission on Stratigraphy, the body charged with formally designating geological time periods, decided the Anthropocene concept “has some merit.” To investigate further they formed the Anthropocene Working Group, which published their initial findings this past February in a special issue of the Philosophical Transactions of the Royal Society A. The group reported a wide range of human impacts that could leave a stratigraphically significant mark on the planet's geological record. There is no doubt that humans have changed the world we live in, but has the change been significant enough to declare a whole new epoch? The Anthropocene debate is continuing this week at the 2011 Geological Society of America conference.

Recently, the 3^rd Nobel Laureate Symposium decided to hold a trial, charging humanity with ruining the planet. Based on the so called 9 Planetary Boundaries, a jury of 20 Nobel Laureates sat in judgment while “compelling evidence” was presented showing that “humanity may now be capable of radically altering the remarkable conditions for life on Earth.” The Planetary Boundaries approach was developed by 28 scientists, who estimated that three of the boundaries, climate change, the nitrogen cycle and biodiversity loss, have already been crossed and that several others are all ready in dangerous territory. We have all been charged with transgressing boundaries laid down by a group of scientists most people have never heard of, judged and found guilty by a gaggle of Nobel Prize winners, and been remanded to the UN for punishment. This sham trial does not represent justice but an attempt to place humanity in ecological bondage.

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.

There has been a resurgence of alarmist claims regarding the pending extinction of a majority of Earth's lifeforms due to human misdeeds—clearing rain forests, polluting the oceans and, of course, causing global warming. Perennial crank and misanthrope E. O. Wilson leads the parade of doomsayers, claiming that biodiversity is dropping and a sixth major extinction event is just around the corner. What evidence backs these claims? Why, computer model projections, naturally. The facts are researchers have identified 1.4 million animal species so far, and recently a pair of Brazilian researchers estimated that there are estimated 5.4 million yet-to-be-discovered animal species alone. The truth is, scientists have no idea how fast biodiversity is falling because they have no idea how many species there are on Earth. And the researchers put a price tag on finding out that is simply stunning.

Time after time, the public has been harangued by climate change “experts” predicting all form of devastation due to anthropogenic global warming. The Greenland and Antarctic glaciers will melt, as will the sea ice covering the Arctic Ocean. Temperatures will rise by 2-6°C, perhaps more in higher latitudes. Weather patterns will shift, there will be droughts and torrential monsoon rains, cyclones will increase in intensity—where will it all end? Here's a thought, we might find the world a nicer place after a bit of global warming. In fact, given the general cooling trend seen over the Holocene (the period since the last glacial period ended around 14,000 years ago) and the Cenozoic (the time since the dinosaurs died, around 65 million years ago) human CO₂ may be, in some small way, the only thing delaying another devastating ice age.

That humans can alter the natural environment is well known. We have been hunting, fishing and clearing land for agriculture for tens of thousands of years. More recently humans have gained the ability to drain swamps, dam rivers, level mountains and pave over darn near anything. Environmentalists think this kind of activity is abhorrent, and go so far as to claim that H. sapiens are responsible for a new major wave of extinctions. In general, animal species can either move, go extinct or adapt to human caused environmental changes. Many biologists will tell you that species just can't evolve fast enough to deal with rate of human induced change. As it turns out, this isn't exactly true.

With the UN trying to promote diminishing biodiversity as the NEXT BIG CRISIS it is interesting to note the chaos among diversity researchers. It is hard to make definitive statements regarding loss of diversity when science can not even tell us how many different creatures there are on the planet. Nevertheless, the UN has launched the International Year of Biodiversity, warning that the ongoing loss of species around the world is affecting human well-being. Yet another UN generated “science based” crisis to keep the world's citizens in a frenzy—shades of the failed global warming crisis, which the UN is rather hoping we all will forget.

Evidently 2010 is the International Year of Biodiversity, a year long celebration of Earth's glorious variety of species and ecosystems. Unfortunately, the 1992 Convention on Biological Diversity (CBD) has failed to meet its ambitious goal: a significant slowdown in biodiversity loss by 2010. The AAAS journal Science has acknowledged this celebration with special News Focus section and a Review article. “After failing to meet its major conservation goal, the Convention on Biological Diversity is setting new targets for stemming the loss of species,” its lead article states. But the news is not all bad. In some countries, conservation efforts have helped species recover and reportedly large-scale deforestation in the Amazon has declined by 47.5% over the past 12 months. With eco-alarmists shifting their panicked attention from climate change to biodiversity, it is time to look at the facts.

With the oil disaster in the Gulf of Mexico emboldening all the denizens of the eco-underground, some voices are once again calling for increased production of biofuels—ethanol and biodiesel—and accelerated research into clean coal. Ignoring the fact that biofuels take as much energy to produce as they provide and that they are only competitive with heavy government subsidies, biofuel boosters are again trying to sell their snake-oil to the public. But the single most damning aspect of biofuel production is the exorbitant amount of water it takes to cook-up a gallon of the stuff. Now it appears that the other great energy scam, clean coal, will also increase water usage—by a whopping 80%. With the world facing a real water crisis in the near future, the last thing any government should be doing is wasting their citizens' money on are “green” energy scams that are really just subsidies for coal companies and big agribusiness conglomerates.

There have been arguments made for increased plant growth due to rising atmospheric CO₂ levels, while others have argued against it. Now it seems that green plants and ocean algae are not the only forms of life involved. Opportunistic microorganisms are stepping in to sop up excess carbon. A new report in the Proceedings of the National Academy of Sciences (PNAS) has identified soil fungi as a major player in accelerating CO₂ absorption. Arbuscular mycorrhizal fungi (AMF) have been identified as an intermediary between plants and other bacterial and fungal populations, acting as a buffer for other soil-borne communities. Existing organisms are not just working harder, new communities are developing to take advantage of increased CO₂ levels, demonstrating that nature possesses self-regulation mechanisms science did not anticipate and has yet to discover.

Climate and environmental scientists have become dependent on computer models in recent decades. The scientific literature and the popular press are filled with strident warnings of impending natural disasters, all predicated on the output of computer programs. The IPCC has solemnly predicted that climate change will drive thousands of species to extinction if anthropogenic global warming is not reined in. The coprophagous press has uncritically swallowed these computer generated droppings, reporting conjecture as fact and possibilities as certainties. Even though the climate change faithful continue to blindly believe the IPCC predictions, at least some researchers are aware of the glaring flaws in their computer models.

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.
