Hele a tady bozi summary na historie klimatologie od americkeho historika a fyzika Spencer Wearta. Jak jsme prisli na to, ze se ohriva - a jak jsme si zavreli cestu, k tomu abysme se vyhnuli nebezpecny klimaticky zmene. Tyve dneska to na me nejak dopada... Cistu si tu historii takhle v kontextu, je tak strasne depresivni.

By the late 1970s global temperatures had begun to rise again. Since the late 1950s some climate scientists had been predicting that an unprecedented global warming would become apparent around the year 2000. Their worries finally caught wide public attention in the summer of 1988, the hottest on record till then. Computer modeler James Hansen made headlines when he told a Congressional hearing and journalists that greenhouse warming was almost certainly underway. And a major international meeting of scientists in Toronto called on governments to undertake active steps to cut greenhouse gas emissions.

The response was vehement. Corporations and individuals who opposed all government regulation began to spend millions of dollars on lobbying, advertising, and "reports" that mimicked scientific publications, striving to convince the public that there was no problem at all. Environmental groups, less wealthy but more enthusiastic, helped politicize the issue with urgent cries of alarm. The many scientific uncertainties, and the sheer complexity of climate, made room for limitless debate over what actions, if any, governments should take.
...

If every nation met its target, what would they achieve? The science remained stubbornly imprecise, for the global climate system is a tangle of many interacting influences. Scientists did know that without stronger and prolonged efforts we were likely to get a rise to 2.5°C or more. That would be a desperately wounded world, where it would be difficult to sustain a civilization that was anywhere prosperous and peaceful. And we would face a small but real risk of triggering unstoppable heating, to a point where it would be difficult to sustain any civilization at all.

Future diplomacy would have to press urgently for stronger pledges and see that they were fulfilled. The world’s climate experts explained that we had delayed action for so long that we could now avoid grave harm only if global emissions did not just level off, but began to plunge by the year 2030. The policies set during the decade of the 2020s would determine the state of the planet’s climate for thousands of years to come. Fortunately, the expense of making the necessary changes in our economic and social systems would be far less than the cost of allowing climate change to continue, and would bring numerous other benefits. Ever more people and organizations saw that the work was in their own interest and began to undertake it.

Citace ze soucasneho draftu ipcc

Climate change will fundamentally reshape life on Earth in the coming decades, even if humans can tame planet-warming greenhouse gas emissions. Species extinction, more widespread disease, unliveable heat, ecosystem collapse, cities menaced by rising seas — these and other devastating climate impacts are accelerating and bound to become painfully obvious before a child born today turns 30.

“The choices societies make now will determine whether our species thrives or simply survives as the 21st century unfolds … But dangerous thresholds are closer than once thought, and dire consequences stemming from decades of unbridled carbon pollution are unavoidable in the short term.”

The actual draft says, “The worst is yet to come, affecting our children’s and grandchildren’s lives much more than our own. We need transformational change operating on processes and behaviours at all levels: individual, communities, business, institutions and governments. We must redefine our way of life and consumption.” The authors go on to say, “current levels of adaptation will be inadequate. Life on Earth can recover from a drastic climate shift by evolving into new species and creating new ecosystems. Humans cannot.” (Emphasis added.)

The faulty science, doomism, and flawed conclusions of Deep Adaptation | openDemocracy
https://www.opendemocracy.net/...nomy/faulty-science-doomism-and-flawed-conclusions-deep-adaptation/

To be totally clear, we argue that all of the following are simultaneously true:

1. There is an unprecedented global climate and ecological emergency. If governments do not undertake enormous measures to mitigate climate change, then some form of “societal collapse” is plausible — albeit in varying forms and undoubtedly far worse for the poorest people.

2. Policymakers and society at large are not treating this grave threat with anything approaching sufficient urgency.

3. The climate crisis is dire enough in any case to justify urgent action, including mass sustained nonviolent disruption, to pressure governments to address it swiftly.

4. However, neither social science nor the best available climate science support Deep Adaptation’s core premise: that near-term societal collapse due to climate change is inevitable.

5. This false belief undermines the environmental movement and could lead to harmful political decisions, overwhelming grief, and fading resolve for decisive action.

6. Respecting the distinction between the coming hardships and unstoppable collapse clarifies our agency to minimise future harm by mitigating and adapting to climate change, whilst freeing us from moral and political blinkers.




The Darkest Timeline

In July, with Colleen Schmidt, who is 24 and has a degree in environmental biology from Columbia — and who acted as their de facto editor — they published a paper.

“I would call it a hit piece on the paper and by implication, the framework and the movement,” Mr. Bendell said. “It was quite upsetting, and I wasn’t sure how best to respond.”

About two weeks after Mr. Hall, Mr. Nicholas and Ms. Schmidt published their paper, Mr. Bendell released a second version of his Deep Adaptation paper.

“This paper appears to have an iconic status amongst some people who criticize others for anticipating societal collapse,” he writes. “Therefore, two years on from initial publication, I am releasing this update.”

The stark statement that had opened the original paper was altered. Once, it had said its purpose was to provide readers “with an opportunity to reassess their work and life in the face of an inevitable near term social collapse due to climate change.” Now, to emphasize that the idea remains unproven, it reads “in the face of what I believe to be an inevitable near-term societal collapse.” Mr. Bendell added a sentence stating plainly that the paper does not prove that inevitability.

As the summer of 2020 ended, he announced on his blog that he would be stepping back from the Deep Adaptation forum, a decision he said he’d been planning for a year.

In this quiet, he is working on a new paper. In it, he said, he plans to explain exactly how the coming catastrophe of our society will play itself out, describing the starvation and mass death that so many anticipate.

The three young people who wrote the paper rebutting Deep Adaptation agree that the climate crisis has already resulted in horrific loss and that it will continue to exact a heavy toll. But they also believe that governments around the world can still make a difference and should be held to account, instead of being lulled into inaction by despair.

“We’ve lost some things,” Ms. Schmidt said. “We could lose everything. But there is no reason not to try and make what can work, work.”

Elon Musk: "The US Is Moving Toward Sustainable Energy"
https://cleantechnica.com/2020/09/27/elon-musk-the-us-is-moving-toward-sustainable-energy/

Despite Donald Trump claiming that he was going to save the US coal industry, it has been dying a quick death under his administration. As CleanTechnica Director Zach Shahan reported yesterday, electricity from coal has dropped from 26.9% to 17.7% in the past few years.

The credit isn’t due to Trump, though — it’s the market doing what it’s been doing for much longer, pushing coal out. CleanTechnica readers knew Donald Trump’s claims that he’d “save” the coal industry were a lie when he made them on the campaign trail. The downward trend for coal was unstoppable. Coal had dropped from 50% in 2005 to 45% in 2010 to 33% in 2015 before the continued drop to 18% in 2020.

Thwaites Glacier is a fragile piece of one of the most rapidly changing places on Earth. That pace of change is what caught people’s attention about two decades ago, Holland says. Thwaites’ elevation falls by several feet every year. Scientists theorize that as the leading edge of a glacier retreats farther inland, the thicker ice above begins flowing down toward the sea faster. This creates a runaway effect of retreat, thinning, further retreat, and, ultimately, collapse.
“If a glacier collapse occurs in the next decade to century, or centuries, it will be here,” Holland says. “And it will be triggered by warm water and be unstoppable.” Thwaites could also trigger ice loss in connecting areas of West Antarctica, scientists believe. “Everything that we’ve seen, particularly from satellite and remote sensing in the last decade or so points to this area becoming more active,” says Paul Cutler, program director of glaciology, ice core science and geomorphology at the National Science Foundation. “And it’s not acting in isolation. If it starts rapidly retreating, it starts acting on the neighboring glaciers as well.”
The ice shelf that Basinski, Holland, and the rest of their team shared from mid-December to mid-January is like an ice cube in a glass of water. Because it’s over the ocean, it won’t directly contribute to sea level rise. But about half a mile away is what scientists call the grounding zone, where this “flowing” piece of Thwaites sitting on the water meets the “grounded” part attached to the seafloor.
