23.10.2020 Greta Thunberg/Medium: The real story of the day

“If you are in denial about climate change, come to California,” Gov. Gavin Newsom said last month.

Officials have worried about cascading disasters. They just did not think they would start so soon.

“We used to worry about one natural hazard at a time,” said Alice Hill, a senior fellow at the Council on Foreign Relations who oversaw resilience planning on the National Security Council during the Obama administration. “The acceleration of climate impacts has happened faster than even we anticipated.” #Climate

Guckt ma, so sieht es grad aus in San Francisco. Die Rauchschwaden stammen von den kalifornischen Waldbränden, die ähnlich verheerend sind wie die in Australien dieses Jahr. #Climate
 

Rising temperatures will cause more deaths than all infectious diseases – study


Rising temperatures are set to cause particular devastation in poorer, hotter parts of the world that will struggle to adapt to unbearable conditions that will kill increasing numbers of people, the research has found.

The economic loss from the climate crisis, as well as the cost of adaptation, will be felt around the world, including in wealthy countries.

Freeman John Dyson... R.I.P., the Free Man

15 December 1923 – 28 February 2020

Freeman John Dyson was an English-born American theoretical physicist and mathematician known for his work in quantum electrodynamics, solid-state physics, astronomy and nuclear engineering. He was professor emeritus in the Institute for Advanced Study in Princeton, a member of the Board of Visitors of Ralston College and a member of the Board of Sponsors of the Bulletin of the Atomic Scientists.

Dyson originated several concepts that bear his name, such as Dyson's transform, a fundamental technique in additive number theory, which he developed as part of his proof of Mann's theorem; the Dyson tree, a hypothetical genetically-engineered plant capable of growing in a comet; the Dyson series, a perturbative series where each term is represented by Feynman diagrams; the Dyson sphere, a thought experiment that attempts to explain how a space-faring civilization would meet its energy requirements with a hypothetical megastructure that completely encompasses a star and captures a large percentage of its power output; and Dyson's eternal intelligence, a means by which an immortal society of intelligent beings in an open universe could escape the prospect of the heat death of the universe by extending subjective time to infinity while expending only a finite amount of energy.

Dyson believed global warming is caused by increased carbon dioxide through burning fossil fuels but that some of the effects of this are favourable and not taken into account by climate scientists, such as increased agricultural yield. He was skeptical about the simulation models used to predict climate change, arguing that political efforts to reduce causes of climate change distract from other global problems that should take priority.

Dyson died after a fall, at a hospital near Princeton, New Jersey, on 28 February 2020 at age 96.

Greenland ice losses rising faster than expected



Greenland is losing ice seven times faster than in the 1990s and is tracking the Intergovernmental Panel on Climate Change's high-end climate warming scenario, which would see 400 million more people exposed to coastal flooding by 2100.

Human Thermal Limits — and when we exceed them


The human body relies primarily upon sweat to cool itself. But if the air is hot enough and humid enough, your sweat no longer evaporates, and sweating for cooling no longer works.

The critical point is a wet-bulb temperature of 35°C. Beyond that, fans don't help. Drinking doesn't help. Shade doesn't help. Rest doesn't help. When the wet-bulb temperature exceeds 35°C, unprotected humans die.

Some areas of the Earth are getting alarmingly close to this limit.
Wetbulb temperatures of 35°C have not yet been widely reported, but there is some evidence that they are starting to occur in Southwest Asia. Climate change then offers the prospect that some of the most densely populated regions on Earth could pass this threshold by the end of the century, with the Persian Gulf, South Asia, and most recently the North China Plain on the front line. These regions are, together, home to billions of people.
When regions cross the 35°C wetbulb limit, they will quite simply become uninhabitable by humans outside of air-conditioned environments. And we simply do not have sufficient power to air-condition that much of the world ... and trying to generate it will only make the problem worse unless we can do so using non-carbon-emitting means.
By 2050, cooling systems are expected to increase electricity demand by an amount equivalent to the present capacity of the US, EU, and Japan combined.
Even then, that heat doesn't just go nowhere; remember, we cool buildings by moving the unwanted heat outside. The more we cool the inside, the hotter the outside gets. Which means we need to turn up the air conditioning to keep the building cool, dumping even more heat outside...

You can see where that's going.

The short version is that if we keep on our current path, in as little as another few decades large areas of our planet are on track to become uninhabitable. And the people who live there now are going to have to either find a new place to live, or die.

Finding new places is going to be very hard. Look at all the resistance to the relatively tiny refugee movements happening today. If we pass 35°C wet-bulb, entire nations may need to relocate. And a LOT of them are going to die.
