Laut dem europäischen #Copernicus #Climate #Change #Service und der US-amerikanischen #Oceanographic #and #Atmospheric #Administration war der Juli 2019 der heißeste Monat, der weltweit je verzeichnet wurde. Doch nicht nur der diesjährige – jeder Juli der letzten fünf Jahre zählt zu den fünf heißesten Monaten der #Messgeschichte.

The Coming Migration out of Sub-Saharan Africa | National Review


#politics #climate #migrations

If Rome and Berlin have been transfixed by a nautical incident involving only a few dozen African seafarers, it is for a simple reason: There are a billion more where those came from. And how Europe addresses African migration is going to determine what the population of the continent looks like a generation from now.

'It feels like something out of a bad sci-fi movie'


A top #climate scientist quit #USDA, following others who say #Trump has politicized #science.
Lewis #Ziska, a 62-year-old #plant physiologist who’s worked at USDA’s Agricultural Research Service for more than two decades, told POLITICO he was alarmed when department officials not only questioned the findings of the #study — which raised serious concerns for the 600 million people who depend on #rice for most of their #calories — but also tried to minimize #media coverage of the paper, which was published in the journal Science Advances last year.

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.

1 in 5 #Cities Is About to Have a #Climate Unknown to Any Place on Earth

Scientists from the #CrowtherLab at #ETHZurich have for the first time visualised how these climate shifts will play out on a global scale, looking at how conditions in 520 major cities around the world are predicted to change in just three decades.

"By using optimistic #ClimateChange scenario, we represent conservative changes in conditions ..."

Whole ecosystems are shifting dramatically north in the Great Plains, according to analysis of birds.

"The northernmost ecosystem boundary shifted more than 365 miles north, with the southernmost boundary moving about 160 miles from the 1970 baseline."

"To arrive at their conclusions, the researchers analyzed 46 years' worth of avian data collected for the North American Breeding Bird Survey, a US Geological Survey program designed to track bird populations. That survey included more than 400 bird species found within a 250-mile-wide transect stretching from Texas to North Dakota."

"The team then separated bird species into groups based on their body masses and searched for gaps in the distribution of the groups. Those gaps effectively act like the DNA signature of an ecosystem, allowing the team to identify where one ecosystem ends and another begins."

"Over their study area, and over time, the researchers identified three distinct ecosystem boundaries, with a fourth -- and thus a fourth ecosystem regime -- appearing in the final decade."

"The fact that the northernmost boundary shifted more than its southernmost counterpart reflects a well-documented phenomenon known as Arctic amplification, suggesting that climate change is at play."

Analysis finds U.S. ecosystems shifting hundreds of miles north

#ClimateChange: Why is it so often “sooner than predicted”?

A June 15th headline elicited feelings in me of both shock and déjà vu: “#Climate #change: #Arctic #g permafrost now melting at levels not expected until 2090” [Independent, June 15, 2019]. Shock because that’s quite a bit ahead of time. Déjà vu because how often does a climate change headline or story use a phrase like that? “At levels not expected until” ...

Another Good Reason to Fix Global Heating

“It was incredible, really incredible”, she recalls while speaking to me from The Woods Hole Research Center, Massachusetts, where she is an associate scientist. “I still get chills when I think about it… I just couldn’t believe the magnitude: collapsing cliffs the size of multi-storey buildings … and as you walk along you see what look like logs poking out the permafrost. But they aren’t logs, they are the bones of mammoths and other Pleistocene animals.”

In November, when temperatures should have been -25C, a temperature of 1.2C above freezing was recorded at the North Pole. The Arctic is warming twice as fast as the rest of the world (in part due to the loss of solar reflectivity).

"There is a lot we can do, she says. The fate of the Arctic is not a foregone conclusion: “The actions taken by the international community will have a substantial impact on just how much carbon will be released and how much of the permafrost will thaw. We need to keep as much of the permafrost as we can frozen. And we do have some control of that.” Our emissions cannot remain “business as usual”. The Arctic depends on it. And we depend on the Arctic."
If this melting continues,
- 130-150 billion tonnes of CO2 and methane (both strong greenhouse gasses) may be released as bacteria break down material as it thaws. This is as much as current US CO2 production per year, for another 80 years.
- Melting permafrost destroys local ecologies, creates sinkholes, floods, and erosion.
- Bacteria and viruses thaw and become active again; "A French study in 2014 took a 30,000 year-old virus frozen within permafrost, and warmed it back up in the lab. It promptly came back to life..." It is likely humans have little resistance to many such diseases.
- Micro-plastics will also be released. "Due to circular global marine currents, much plastic waste ends up in the Arctic, where it becomes frozen in sea ice or permafrost. A recent study of marine micro-particles demonstrated that concentrations were higher in the Arctic Basin than all other ocean basins in the world. Microplastic concentrations in the Greenland Sea doubled between 2004 and 2015 [due to melting and runoff]."
- "Mercury is also entering the food chain, thanks to thawing permafrost. The Arctic is home to the most mercury on the planet. The US Geological Survey estimates there’s a total of 1,656,000 tonnes of mercury trapped in polar ice and permafrost: roughly twice the global amount in all other soils, oceans, and atmosphere."
- Uncovered archaeological treasures may just wash away in the subsequent floods.
