We don’t know how long we have. The more we heat up the planet, the more we reach “tipping points,” where “positive feedback loops” that we set in motion become Earth’s way of consuming itself. Our models for predicting effects of human-caused climate change do not — cannot — take into account the potential for the feedback loops running out of control, beyond reach of any mitigating efforts we may make.
So, what, then?
We have to simply stop feeding carbon into the air. Just stop, in every way we can, as much as possible, everywhere, and punish those who resist. They don’t call it “an existential threat” for nothing. Why treat it as less?
Lesser efforts, lesser objectives, raise the risk beyond our ability to measure, as shown below in the new PBS Nova episode, “Arctic Sinkholes.”
As the authors explain, the craters look like sinkholes to the naked eye, but they are not sinkholes. They are massive, explosive and incessant methane leaks from the arctic permafrost.
The rate of increase in the arctic temperature is twice that of the planetary average. The permafrost — ground frozen continuously for at least two years, but also thousands of feet deep for millennia — is thawing, and opening big methane vents at alarming rates.
We don’t know how many there are, or will be. We don’t know their ultimate effect. We don’t know if our feeble efforts to stop killing our planet can begin to take into account the effects of thawing permafrost.
The craters (above ground and under water) are examples of earth’s chain reaction to climate change. They are examples of Earth’s natural amplification of our harmful influence. One might say they are examples of Nature’s way of getting rid of us, eventually.
The Nova episode shows other examples, too, beyond the methane craters. In one case, a relatively small human impact set in motion an endlessly growing, massive reaction that we have no way to stop. They show it to you on camera, not in a theory. They know what caused it. They know there’s nothing we can do about it. It is only one example.
We don’t know how much we don’t know, but those paying attention know the ignorance is terrible, especially because at least half of us don’t think we are ignorant, and far too many think that science is just a matter of feelings and personal opinions.
The Trumpoid diseased psyche thinks that truth is whatever it believes, irrationally, or that reality is whatever feeds its delusional superiority driving the conviction that it knows better about which it knows nothing. The rest of us are mostly sleeping about this, treating it as mere politics. Wake the hell up to science.
Below is the YouTube copy of the Nova video (Season 49 Episode 1 | 53m 28s) that premiered today, February 2, 2022 (cute: 2/2/22). You can also watch it and related episodes at the PBS Nova Arctic Sinkholes website.
In the Arctic, enormous releases of methane, a potent greenhouse gas, threaten the climate. Colossal explosions shake a remote corner of the Siberian tundra, leaving behind massive craters. In Alaska, a huge lake erupts with bubbles of inflammable gas. Scientists are discovering that these mystifying phenomena add up to a ticking time bomb, as long-frozen permafrost melts and releases vast amounts of methane, a potent greenhouse gas. What are the implications of these dramatic developments in the Arctic? Scientists and local communities alike are struggling to grasp the scale of the methane threat and what it means for our climate future. © 2022 WGBH Educational Foundation.
What do you think? Is it reactionary, alarmist, overreactive bleeding heart environmentalist tree-hugger terrorism, or is it rational, scientifically sensible, legitimate concern that puts this post in my blog?
I hope that my question is the least of your concerns on the topic. I hope that you question me, especially if you are afflicted with the delusion that human provoked climate change is not real. Tell me three reasons you think so. You can’t. There aren’t any. But go ahead. Be stupid. Tell me anyway.
