Earth Wavers On The Edge Of Dangerous Tipping Point

Earth Wavers On The Edge Of Dangerous Tipping Point

Human behavior is accelerating climate change, and setting in motion a chain of events that may put the future of our species in jeopardy. Those who acknowledge the negative impact of human development accept this and desperately want to do something about it. We find it hard to swallow when others refuse to†acknowledge or even consider the scientific facts that prove humans are altering the Earth’s climate in dangerous ways.

The sad truth is that denying climate change won’t prevent it from happening. In fact, a new study†published in Thursday’s edition of the journal†Nature shows that the planet is approaching a dangerous climate tipping point, and our†destructive habits are pushing it toward the edge.

Throughout the eons the Earth has gone through several drastic biological changes, many of which wiped out thousands of then-living species in traumatic mass extinctions.†”Humans are now forcing another such transition, with the potential to transform Earth rapidly and irreversibly into a state unknown in human experience,” wrote the study’s international panel of authors.

The researchers say a combination of variables are forcing the planet toward irreversible biological changes, including†exploding global population, rapidly rising temperatures and the clearance of more than 40 percent of Earth’s surface for urban development or agriculture.†They also warn that ignoring these changes, and our role in fast-tracking them, is a dangerous gamble.

“The net effects of what we’re causing could actually be equivalent to an asteroid striking the Earth in a worst-case scenario,” the paper’s lead author, Anthony Barnosky, a professor of integrative biology at UC Berkeley, said in an interview with the LA Times. “I don’t want to sound like Armageddon. I think the point to be made is that if we just ignore all the warning signs of how we’re changing the Earth, the scenario of losses of biodiversity ó 75% or more ó is not an outlandish scenario at all.”

No, the Earth isn’t going to suddenly implode because there are too many SUVs or because you leave the air conditioning running when you’re not home. But if deforestation, population growth, and consumption of fossil fuels continues at the current pace, our children will be left†with “a biologically impoverished Earth that would rob humans of vital ecological services such as insects that pollinate crops, forests that provide clean water, and tropical species that are the source of new drugs.”

Yet again, scientists are echoing what environmentalists have been saying for decades: even if we can’t agree on what’s causing climate change, we must acknowledge that IT IS happening and WE ARE making it worse. Doing so will allow us to prepare for what’s ahead, and minimize the negative impact on society. Refusing to acknowledge that our actions have consequences only guarantees that they will be swift and severe.

One of the best quotes i ever heard was:

"We are destroying our planet's ability to heal herself"

One of the most dangerous delusions of mankind is that you can have infinite growth on a finite planet yet economists above all seem to believe this is possible. Instead of growth economics we need steady state or preferably contraction economics. The truth is that such a small planet can support more than 7 billion large primates is nonsense and any biologist believes that. We are showing, courtesy of capitalism, no more intelligence than a confluent bacterium on a blood agar plate. Our political masters eg Harper are the puppets of the one percent and are wilfully ignorant of the inevitable population crash that must occur if the deadly combination of numbers of hominids and their increasing consumption of the
biosphere continues.
The Chinese have shown the way forward with their one child family and we need a new morality that makes greed the deadliest of the seven such sins. Good Luck Humanity

I have the unique opportunity of working at a school, and get to go to classes with many students. Our youth have some great ideas to help with some of these problems, too bad they aren't listened to now. As they get older, they may not want to speak out so well and do anything about what they see as they are learning...we all need to take care of our Earth.

It is the capitalistic ideology that encouraged consumerism, which in turn drives production of of less than quality goods.
But , politics is so ingrained in society and it is politics that sadly drives the economy. Politicians are NOT the powers that be- they are in the back-pockets of the filthy rich and powerful. Fracking is now a big problem, urban development encroaches on natural habitats, electronic waste is a global dilemma, etc.,etc.,etc.
What of climate change? There are more cynics than there are believers in humans being responsible for this planet, the earth is not for human beings to destroy- but destruction is going to far and out-of control.Perhaps, your message can get through even just ONE non-believer, that is a great step.
