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.

This moment, when you are completely taken by the simple fact, that you use a #source #code based #linux #meta-distribution, so you're #compiling every single #program you use and every single #update it gets on your own machine....

If i would look at this realistically ... i could grab my monthly #power #bill and calculate how much #kWh i "wasted" only for #compiling #stuff................ That way, i have my very own part on the #climate #change problematic. :(

How the Amazon forest regulates #climate

The #Amazon #forest is the world’s largest #tropical forest.No other place in the planet has more #animal and #plant #diversity.
Around 20% of all #freshwater in the planet discharges into the #oceans through the Amazon river. The thick #vegetation of the region is critical to retain all this water here.

The scale of the #climate and wildlife #crises has been laid bare by two landmark reports from the world’s scientists. In October, they said #carbon emissions must halve by 2030 to avoid even greater risks of drought, floods, extreme heat and poverty for hundreds of millions of people. In May, global scientists said human #society was in jeopardy from the accelerating annihilation of #wildlife and destruction of the ecosystems that support all life on #Earth.

| ZUM THEMA BLAUMACHEN FÜRS WELTKLIMA:
„Was WissenschaftlerInnen und Umweltschutzverbände weltweit seit Jahrzehnten zu propagieren versuchen, haben Gretas Freitagsdemos über Nacht Gehör verschafft. Die Klimakrise hat jetzt zumindest die Brisanz erlangt, die sie verdient. Wenn es noch irgend möglich sein sollte, die veränderungsresistenten Verkrustungen in der Wirtschafts- und Energie-politik (welche sich mancherorts sogar in Form von ignoranter Antiklimapolitik manifestieren), global aufzubrechen, dann ist die weltweit klimastreikende Jugend mit ihren Fridays-for-Future-Demos unsere einzige Hoffnung. Und dafür dürfen dann auch ein paar Freitage Schule ausfallen.“

True words: Twenty-five years ago people could be excused for not knowing much, or doing much, about climate change. Today we have no excuse.

Fabrika bacalarından çıkmakta olan kimyasal fazlar, dumanlar ve tozlar havanın kirlenmesine neden olur. Kirlenen hava aynı zamanda bölgede yaşayan insanların sağlığını da tehlikeye sokmaktadır. Özellikle akciğer hastalıkları bu dumanlardan dolayı ortaya çıkıyor. Enerji elde etmek için yakılan yakıtlar ozon tabakasının delinmesine neden olmaktadır.

| ‚Scientists for Future‘ unterstützen die ‚Fridays for Future‘-Klimastreik-Bewegung. Hier weitere Kernaussagen, warum ‚Fridays for Future’ begründet sind:
„Die Fridays for Future-Bewegung hat den Zentralnerv des deutschen Bildungsideals getroffen, indem sie die Frage aufwirft: Wofür lernen wir eigentlich, wenn unsere Welt (die in eurer Verantwortung liegt) bald kollabiert? – Jetzt wäre der richtige Moment, an allen deutschen Schulen in einen Klimaschutz-Dialog einzutreten. Dadurch bekäme Schule wieder Sinn.“

🌏🔥 Le Parlement irlandais est devenu jeudi soir le second à déclarer "l'urgence climatique", dix jours après le Royaume-Uni. La nouvelle a été accueillie avec enthousiasme par la jeune militante @gretathunberg Thunberg, qui veut aller encore plus loin.
.

Un amendement à un rapport parlementaire pour déclarer "une #urgenceclimatique " et demander au Parlement "d'examiner comment (le gouvernement irlandais) peut améliorer sa réponse au problème de la perte de #biodiversité" a été approuvé sans vote. "Nous avons maintenant l'appui de tous les partis pour déclarer une urgence en matière de #climat et de biodiversité", s'est félicitée sur Twitter Hildegarde Naughton, députée du parti au pouvoir #FineGael (centre-droit) et présidente du comité sur l'action climatique au Parlement. Mais "maintenant, on a besoin d'action", a-t-elle souligné.

Agir concrètement "Déclarer une urgence ne veut absolument rien dire à moins que des mesures ne soient prises pour la sauvegarder", a aussi déclaré le chef de file du Parti vert, Eamon Ryan. "Cela veut dire que le gouvernement devra faire des choses qu'il ne veut pas faire", a-t-il ajouté.

L'objectif actuel du gouvernement irlandais est une réduction des émissions de gaz à effet de serre d'au moins 80% par rapport à 1990 d'ici 2050, selon le site du département pour l'action climatique irlandais.
