The Dying Planet - 06/06




NASA satellites are keeping a close watch on the massive wildfires burning in southern British Columbia.

A satellite captured today’s space view of the South Coast of the province: a massive thick blanket of wildfire smoke covers much of the Lower Mainland, the Strait of Georgia, the southern half of Vancouver Island and parts of the Olympic Peninsula in Washington State.

The smoke caused an eerily orange, Martian sky over the Metro Vancouver region this morning. Conditions improved by noon, but persisting smog and high concentrations of fine particulate matter prompted local officials to issue an air quality advisory.





Germany broke its all-time heat record on Sunday July 5, when the mercury soared to 104.5°F (40.3°C) at the official Kitzingen station in Bavaria. According to the German weather service's Facebook page, the record is now confirmed as official. The previous official national heat record recognized by the German meteorological agency (DWD) was 104.4°F (40.2°C), set in July 1983 and matched in August 2003. Numerous cities in Germany set all-time heat records over the weekend, including Saturday's 100.2°F (37.9°C ) reading at Berlin's Dahlem station, which has a very long period of record going back to 1876. Frankfurt beat its all-time heat record on Sunday--both at the airport (38.8°C) and downtown (39.0°C). Thanks go to weather records researcher Maximiliano Herrera and Klimahaus' Michael Theusner for these stats.


Warm, humid weather gives way to an unsettled forecast.



Scientists at the UN climate negotiations in Bonn warn that new data about the melting of the Earth’s permafrost, and projections of a “permafrost carbon feedback loop,” suggest that the Earth is reaching thresholds where only a new ice age could reverse the impacts of global warming.

Guy McPherson is a professor emeritus of evolutionary biology, natural resources and ecology at the University of Arizona, and has been a climate change expert for 30 years. He has also become a controversial figure, due to the fact that he does not shy away from talking about the possibility of near-term human extinction.

While McPherson's perspective might sound like the stuff of science fiction, there is historical precedent for his predictions. Fifty-five million years ago, a 5-degree Celsius rise in average global temperatures seems to have occurred in just 13 years, according to a study published in the October 2013 issue of the Proceedings of the National Academy of Sciences. A report in the August 2013 issue of Science revealed that in the near term, earth's climate will change 10 times faster than during any other moment in the last 65 million years.
Prior to that, the Permian mass extinction that occurred 250 million years ago, also known as the "Great Dying," was triggered by a massive lava flow in an area of Siberia that led to an increase in global temperatures of 6 degrees Celsius. That, in turn, caused the melting of frozen methane deposits under the seas. Released into the atmosphere, those gases caused temperatures to skyrocket further. All of this occurred over a period of approximately 80,000 years. The change in climate is thought to be the key to what caused the extinction of most species on the planet. In that extinction episode, it is estimated that 95 percent of all species were wiped out.
Today's current scientific and observable evidence strongly suggests we are in the midst of the same process - only this time it is anthropogenic, and happening exponentially faster than even the Permian mass extinction did.
In fact, a recently published study in Science Advances states, unequivocally, that the planet has officially entered its sixth mass extinction event. The study shows that species are already being killed off at rates much faster than they were during the other five extinction events, and warns ominously that humans could very likely be among the first wave of species to go extinct.
So if some feel that McPherson's thinking is extreme, when the myriad scientific reports he cites to back his claims are looked at squarely and the dots are connected, the perceived extremism begins to dissolve into a possible, or even likely, reality.
The idea of possible human extinction, coming not just from McPherson but a growing number of scientists (as well as the aforementioned recently published report in Science), is now beginning to occasionally find its way into mainstream consciousness......






In this hot, dry summer, even the Queets rain forest in Olympic National Park is burning. It’s a rare spectacle, but one that could become more common.

Fire crews call them “cat faces,” deep holes that flames have burned into the trunks of the centuries-old Sitka spruce and hemlock growing here in the Queets River valley.

The trees may smolder for days — spouting smoke from their bases before finally toppling to the ground with a thunderous crash that sounds like a bomb has gone off.

They are falling down regularly,” said Dave Felsen, a firefighter from Klamath Falls, Ore. “You can hear cracking and you try to move, but it’s so thick in there that there is no escape route if something is coming at you.”

This year, even the Queets rain forest, a place that typically receives more than 200 inches of rain annually, is burning.

The fire started after a warm winter prevented most of the snowpack from forming, followed by an exceedingly hot, dry spring that primed the forest for ignition. The result of this unusual alignment is what now ranks as the largest fire since the park was established, and might burn through the summer......

As buses full of evacuees began to roll into Cold Lake, Alta., ash was falling like snow in the coastal town of Powell River, B.C., and flames and smoke were threatening La Ronge in Northern Saskatchewan.

Propelling them all were wildfires, which are burning by the dozens in Western Canada.

On Sunday morning, a pall of smoke hung over Vancouver as fans were hitting the streets for the Women’s World Cup soccer final between United States and Japan.
