Could abrupt climate change lead to human extinction within 10 years?

One of the world's most outspoken climate-change Cassandras is U.S. conservation biologist Guy McPherson.

A professor emeritus of natural resources and the environment at the University of Arizona, he's warned that sharply rising methane emissions are going to create a catastrophe in our lifetimes.

McPherson, author of Going Dark, has even predicted the near-term extinction of many species, including human beings, by the middle of 2026.

It's because of something called abrupt climate change, also known as nonlinear climate change.

This results when feedback loops caused by rising atmospheric greenhouse gas levels cause the climate system to rapidly transition to a different mode, occurring on a scale that human or natural systems cannot adapt to.

In the first two decades after methane is released into the atmosphere, it's about 85 times more powerful as a heat-trapping gas than carbon dioxide.

Large amounts of methane are stored in "clathrates", which are chemical substances along the Arctic continental shelves storing methane molecules.

McPherson and coauthor Carolyn Baker addressed this in their 2014 book, Extinction Dialogs: How to Live with Death in Mind.

On his website, McPherson criticizes scientists, who know about this problem, for not doing nearly enough to educate the public. He also blames politicians and the leaders of corporations and nongovernmental organizations for not raising the alarm.

"Worse than the aforementioned trolls are the media," MacPherson writes. "Fully captured by corporations and the corporate states, the media continue to dance around the issue of climate change. Occasionally a forthright piece is published, but it generally points in the wrong direction, such as suggesting climate scientists and activists be killed (e.g., James Delingpole’s 7 April 2013 hate-filled article in the Telegraph). Leading mainstream outlets routinely mislead the public."

Writer says jet stream changes are having an effect

A recent post on the Arctic News blog by its editor, Sam Carana, has even declared that human extinction could occur within a decade. Carana cites "the decreasing difference in temperature between the Equator and the North Pole causes changes to the jet stream, in turn causing warmer air and warmer water to get pushed from the North Atlantic into the Arctic".

"Warmer water flowing into the Arctic Ocean in turn increases the strength of further feedbacks that are accelerating warming in the Arctic," Carana writes. "Altogether, these feedbacks and further warming elements could trigger a huge abrupt rise in global temperature making that extinction of many species, including humans, could be less than one decade away."

At the root of this extinction prediction is methane, which is being released from sea floors along continental shelves in the Arctic as a result of melting ice.

The Counterpunch website has an article by Dave Lindroff explaining how this could rapidly increase the average global temperature by three degrees Celsius over pre-industrial times.

Lindroff suggests this would be "enough to actually reverse the carbon cycle, so that plants would end up releasing more carbon into the atmosphere rather than absorbing it".

This is what abrupt climate change looks like.

McPherson has maintained that abrupt climate change could even result in the average global temperature soon rising four degrees Celsius over pre-industrial times. Many scientists warn that increases of just two degrees will cause enormous havoc; four degrees is unfathomable.

"As we’ve known for years, scientists almost invariably underplay climate impacts (James Hansen referred to the phenomenon at “scientific reticence” in his 24 May 2007 paper about sea-level rise in Environmental Research Letters," McPherson writes on his website. "And in some cases, scientists are aggressively muzzled by their governments."

Not likely but also not beyond the realm of possibility. I think man will likely destroy himself before the Climate is done doing it!

Are not enough people drinking the kool aid? Have the funds begun to dry up? Need a new scare tactic.

If it has been like any of the previous predictions using the climate change models, I think we are quite safe for a long time to come.

Not as long as we have lots of firewood.

That's funny.

The climate change models don't predict the crossover point for at least another 50 years.

Priceless

It's a conspiracy he says.

Now that is funny

Since our money is worth less than good firewood I don't see a problem.

Teach them what?

About the climate change fake news/corporate/state conspiracy to cover up the doomsday theory?
