Existential Abrupt Climate Change Risks to Humanity: Part 1 of 3 // June 7, 2019
First of three videos. Humanity is stressing vital life-support systems on Earth to the breaking point. It is incomprehensible to a thinking person like myself how:
- the vast majority of the public continues to be blissfully unaware of the clear and present dangers that we face.
- For many years I have been dutifully trying to take the latest cutting edge science on global Earth system changes, and:
- translate it into easily understandable layperson language,
- so more and more of the general public can understand the reality and truth about the extent of devastation to
- our life-support ecosystems on Earth.

‘According to the paper, climate change poses a “near- to mid-term existential threat to human civilization,” and there’s a good chance society could collapse as soon as 2050 if serious mitigation actions aren’t taken in the next decade‘.

Paul Beckwith, Climate System Scientist 
Hi. Really appreciate your insights and forthright comments, particularly the gross misunderstandings which the formal scientific community appear to have regarding David Wallace-Wells writings. They appear to ignore his riffs and explanations on his work in interviews, podcasts, etc.
On this, and Chernobyl, while the implications for humanity with respect to conventional use of nuclear power are severe, the assessment of the immediate vicinity of the Chernobyl area as a zone which excludes life is incorrect. This is important, because it allows the comparison of the relative risk of a major nuclear accident to what appears to be the inherent toxicity of humanity.
Censuses of wildlife in the vicinity of Chernobyl show that while the area is no doubt hazardous to life, the evacuation of human beings from the region, in fear of radiation effects, has been a boon to local fauna, resulting in an emergence of effectively a wildlife preserve. See https://doi.org/10.1016/j.cub.2015.08.017
The implications of this, of course, are that human habitation and development are at least as toxic for wildlife as a nuclear accident. Anyone who has witnessed the systematic development of otherwise natural areas and wetlands in favor of McMansions and other natural travesties can only agree. Facts are that human current values and lifestyles are toxic to the biosphere.
This may imply the biosphere might be better off without us than with us, although I dearly hope that is not so, and we might embrace the anti-development values of one Thoreau in Walden, and learn those.

I think Paul is first class, period. I even had a cat named Sagwa which was Shackelton’s twin, and just as entertaining.
As much as I enjoy Paul’s comments and practical information, I am somewhat perplexed by the fact that Paul never includes the ‘Global Dimming’ phenomena which seems, to me at least, just as important an issue as that of ‘Global Warming’.
Last summer in the Okanagan Valley of B.C where I live, and where day temperatures often reach the mid thirties, there was a heavy cover of smoke from distant wildfires for almost 2 months, with smoke-filled skies so thick that the air over our city was as dangerous to breathe as any on the planet.
The most significant observation however was the following:. On very bad days, and there many, the high temperatures that were forecast were at least 4 to 5 degrees BELOW those that were predicted, thereby apparently cooling the usual sun-baked beaches enough that they were practically empty. My own conclusion, although not based on any scientific analysis per se, was that the masking effect of smoke-laden particulates in the air was important enough to lower the daily temperatures by 4-5 degrees, which, to me, was a clear sign that Global Dimming is an important and vital component of climate changes, perhaps even more important than the warming effect produced by fossil fuel emissions.
And so Paul, as much as I am most impressed by your information and in-depth analysis of climate change conditions, I am somewhat curious by the absence of any reference to the Global Dimming phenomena in your reports. ????? and I do hope that some of your followers will be asking the same question…
From my perspective, if we’re going to make a stab at saving our hides from climate change, the issue of Global Dimming may, repeat, MAY, be more significant than any other and must be taken in full consideration of its potential importance in getting it right.
Thanks for reading,

P.S. I used to live near your neck of the woods, literally in the woods of the Laurentians at Lake Simon near Cheneville. I only mention that because I’ve been told that the lake level this spring is at a record high….another probably consequence of climate changing effects.
