Catastrophic Canadian Wildfire Is a Sign of Destruction to Come

By Mark Fischetti, Scientific American

Less snow and warmer spring mean more acres burned

he intense wildfire that has forced thousands of people to evacuate Fort McMurray and surrounding areas in Alberta arrived early in the wildfire season, fueled by hot, windy weather. Scientists say big fires will ignite sooner and sooner in the year in the western U.S. and Canada as the snow pack continues to dwindle during warmer winters or dries out sooner during warmer springs, leaving terrain parched for more weeks of the year. In the American West a 1-degree Celsius rise in average temperature could increase the annual acreage burned by up to 600 percent in certain regions. See the map below for details.

A note of caution regarding our comment sections:

For months a stream of media reports have warned of coordinated propaganda efforts targeting political websites based in the U.S., particularly in the run-up to the 2016 presidential election.

We too were alarmed at the patterns we were, and still are, seeing. It is clear that the provocateurs are far more savvy, disciplined, and purposeful than anything we have ever experienced before.

It is also clear that we still have elements of the same activity in our article discussion forums at this time.

We have hosted and encouraged reader expression since the turn of the century. The comments of our readers are the most vibrant, best-used interactive feature at Reader Supported News. Accordingly, we are strongly resistant to interrupting those services.

It is, however, important to note that in all likelihood hardened operatives are attempting to shape the dialog our community seeks to engage in.

Adapt and overcome.

This is the second year in a row that Northwest winds have turned Minnesota Sunsets spectacularly red, and makes it smell like a bonfire is burning nearby wherever you are.

Ironically, or is it really irony, not retribution, that the blaze has destroyed Fort McMurray, the heart of the Tar Oil Industry in Alberta?

We can't take in the scope of all the possible changes with climate warming. This is definitely a warning. We must stop drilling oil and gas and storing them now. I can hear propane tanks popping from forest fires all around the planet - and what about drill sites, gas storage areas, rivers full of fracking waste and nuclear plants near such sites? What if the Alberta fire moved north, for example?

Another wake-up call re climate change;

Here are important reasons why everyone should be concerned about climate change:

Here are ten reasons we all should be very concerned about climate change:
1. Science academies worldwide, 97% of climate scientists, and 99.9% of peer-reviewed papers on the issue in respected scientific journals argue that climate change is real, is largely caused by human activities, and poses great threats to humanity. In December, 2015, 195 nations at the Paris climate change conference all agreed that immediate action must be taken to avert a climate catastrophe.
2. Every decade since the 1970s has been warmer than the previous decade and all of the 17 warmest years since temperature records were kept in 1880 have been since 1998. 2015 is the warmest year globally since 1880 when temperature records were first kept, breaking the record held before by 2014.
3. Polar icecaps and glaciers worldwide have been melting rapidly, faster than scientific projections.
4. There has been an increase in the number and severity of droughts, wildfires, storms, and floods. Seems to be stories about this almost daily on TV news.
5. California has been subjected to so many severe climate events (heat waves, droughts, wildfires, and mudslides when heavy rains occur) recently that its governor, Jerry Brown, stated that, “Humanity is on a collision course with nature.”

Following up on my previous post, here are additional reasons why everyone shopuld be concerned about climate change:

6. Many climates experts believe that we are close to a tipping point when climate change will spiral out of control, with disastrous consequences, unless major positive changes soon occur.
7. While climate scientists believe that 350 parts per million (ppm) of atmospheric CO2 is a threshold value for climate stability, the world reached 400 ppm in 2014, and the amount is increasing by 2 - 3 ppm per year.
8. While climate scientists hope that temperature increases can be limited to two degrees Celsius (3.6 degrees Fahrenheit), largely because that is the best that can be hoped for with current trends and momentum, the world is now on track for an average increase of 4 – 5 degrees Celsius, which would produce a world with almost unimaginably negative climate events .
9. The Pentagon and other military groups believe that climate change will increase the potential for instability, terrorism, and war by reducing access to food and clean water and by causing tens of millions of desperate refuges fleeing from droughts, wildfire, floods, storms, and other effects of climate change.

It's perhaps unkind to say it, but: There are climate refugees elsewhere in the world (five years of drought is one factor in the Syrian civil war), but this may be the first time that they are coming from a place that is causing climate change.

The blockage to doing something about this is the people with power in the US Senate and Congress. There are too many of them who "believe" that it is all a hoax and they are adamant about blocking any attempt to alleviate the problem. After all, their paychecks from EXXON, Koch bros, etc., depend on a continuation of global warming. As long as there are people like Cruz, Rubio and Inhofe and their supporting staff, nothing effective will be accomplished.

And then there are the masses of sheeple who insist that it is all a hoax and also block efforts to rectify the problem. They also "believe" and won't be changed by facts, but since many of them aren't financially involved in creating global warming, there is some hope that they can be convinced. How do you overcome cognitive dissonance on their part? Facts don't work. What does?

At least one of those Senators ("Smart Jim" Inhofe from Oklahoma, one of the only people ever to go broke in the life insurance business) has admitted publicly, perhaps by accident, that he knows full well that he is lying and does it anyway to support oil and gas interests. Documentation was discovered a year or so ago showing that Exxon did the same thing, starting several years after their own scientists made public their own research with some of the earliest firm documentations of the size of the greenhouse effect prior even to Hansen's bombshell paper.

According to the IPCC. all of Canada and most of the United States are projected to have more rainfall under global warming scenarios. See:

Also more fire. As Martin Gardner, one of my mentors and a mathematician so skeptical that he tended to discount anything for which the empirical evidence was not massive and irrefutable, once said (paraphrasing): There is not enough time to debunk every article of bunk from people who do not understand the terms of the discussion.

He was writing in that case specifically about mathematical theorems, which are one of the purest forms of logical argument, but the point applies more broadly.
