Most people have never heard of the Anthropocene era and with good reason—it is not an officially recognized geologic time period. It is the invention of a small group of scientific busy bodies who evidently have nothing better to do than try to effect a change in the official timeline of Earth's past. The International Commission on Stratigraphy, the body charged with formally designating geological time periods, has been petitioned in the past and just recently a group of chuckle-heads attending the Society for American Archaeology meetings in Hawaii have brought the idea up again. Only problem is, the proponents of the Anthropocene have fallen to arguing amongst themselves—when did the “Age of Man” really start?
The coyote, also known as the American jackal or the prairie wolf, is a canine predator found throughout North and Central America. Ranging from Panama in the south, north through Mexico, the United States and into Canada the wily Canis latrans has been spreading into new territory in the Eastern US, filling a void left at the top of the food chain by the virtual extinction of the gray wolf. But these new coyotes are not the little dog sized creatures from the South West—the new coyote is larger, stronger and more aggressive than his ancestors. Well known as a master of adaptation, new studies over the past few years are now revealing how these relatives of wolves and dogs are evolving into a new top predator thanks to humans. They have expanded their diet to include squirrels, household pets and even deer. Supposedly, coyotes killed a 19-year-old female hiker in Nova Scotia in 2009. It seems that this new breed of predator is actually a wolf in coyote's clothing.
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 3rd 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.
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.
Even with all of the recent scandal surrounding the purveyors of climate change pap, many in the “news media” continue to crank out party-line articles blaming all of Earth's ecological woes on humanity. After decades of trying to alarm the public over a human caused “sixth mass extinction” and more recently, dwindling diversity, some in the media just can't let go of AGW as the root of all evil. A perfect example of this appeared recently in the font of misinformation that is Yahoo News. Blaming every human activity from hunting to climate change, science writer Jeremy Hsu has once again raised the specter of that old shibboleth, the Anthropocene Epoch. This is all a part of a developing trend to elevate falling species diversity to crisis level, mainly because the world's eco-activists need a replacement issue for climate change.
According to a recent paper, human actions may have caused Earth's climate to warm much earlier than previously expected. In an article to be published in Geophysical Research Letters, and widely reported in the media, around 15,000 years ago, early hunters were a major factor in driving mammoths to extinction. Supposedly, this die-off had the side effect of heating up the planet. This is an interesting conjecture, since a letter just published in Nature Geocience reaches the opposite conclusion regarding climate and the mammoths' decline. This mammoth confusion illustrates the uncertain and even contradictory evidence that abounds in climate science.
Once again, scientists propose that planet Earth has been so altered by human activity that we are entering a new geological time period—the Anthropocene. A viewpoint article by some stratigraphic heavy hitters, just published in the journal Environmental Science & Technology, has proclaimed a new age caused by anthropogenic global warming and man's savaging of the environment. According to these experts, the effects of human activity have become so pervasive that Earth has been transformed and the 11,000 year old Holocene epoch is now a “lost world.” Is this really the start of a brave new epoch, one of our own making?
In an essay adapted from his 2009 AAAS Annual Meeting keynote address, James J. McCarthy has produced a fairly concise statement of the anthropogenic global warming believer's world view. After a self-serving review of climate science history, McCarthy trots out the usual litany of climate change troubles: increased cyclones, rain and floods, rising sea levels and, of course, those pesky tipping points. The tone of the article is set early on, when research is cited stating that mankind's impact on Earth is “sufficiently profound to declare that we have transitioned from the Holocene era of Earth history to the Anthropocene.”
