Co se stane, až bude v atmosféře dvakrát více CO2 oproti předindustriálním poměrům?
Reakce globálních teplot na dvojnásobnou koncentraci CO2 se označuje jako klimatická citlivost (climate sensitivity) a po čtyřicet let se téměř neměnně udávala jako 1.5-4.5°C. Na konci července byly ale zveřejněny výsledky čtyřletého výzkumu, který se citlivostí klimatu zabýval a který nově ukazuje, že při dvojnásobném obsahu CO2 s největší pravděpodobností globální teploty stoupnou v rámci intervalu 2.3°C-3.9°C. Studie je velmi rozsáhlá (165 stran) a krom jiného ukazuje, že nárůst teplot pod 2°C má pravděpodobnost menší než 5%. Naopak je šance 6-18%, že by teploty mohly narůst o více jak 4.5°C.

Tak hurikan Laura prichazi do USA.

@capitalweather
So far, Hurricane Laura has intensified at the fastest rate on record for any hurricane in the Gulf of Mexico (tied with Hurricane Karl in 2010). It went from Cat 1 to Cat 4 in 24 hrs.

Hurricane Laura is now forecast to be the strongest storm to ever make landfall along the western Louisiana and north Texas coast, with winds of 145 mph and storm surge of up to 20 feet. But what determines how much devastation a hurricane produces, and what hazards cause the most damage, varies from storm to storm.

Meteorologists rate hurricanes by the intensity of the maximum sustained winds. It's fairly simple: the stronger the winds, the stronger the hurricane:

Category 1: 74-95 mph
Category 2: 96-110 mph
Category 3: 111-129 mph
Category 4: 130-156 mph
Category 5: 157 mph or higher
Any storm that's Category 3 or higher is considered a major hurricane. And the difference in damage between a run-of-the-mill hurricane and a major hurricane is, well, major. And major hurricanes all have a personality of their own, some heavy on wind damage and some heavy on water damage.

Hurricane Laura packs the strongest winds the region has ever seen — but that's not the biggest threat - CBS News

Earthworms that just work on the surface (epigeic worms) don’t make tunnels and are not considered geoengineers.

They are a gardener’s best friend, good for the soil and a treat for birds. But the humble earthworm may not always be good news, according to a study that suggests invasive earthworms could be making Arctic soils too fertile.
The earthworm is not typically thought of as an invasive species. “Most parts of Europe have earthworms so we never really saw them as a problem,” says lead researcher Dr Gesche Blume-Werry, an ecologist from the University of Greifswald in Germany. But Blume-Werry and her colleagues realised that “more and more spots in the Arctic have worms because humans brought them there”.
Earthworms move at around five to 10 metres a year in the Arctic, but human mobility means they can jump from the UK to Svalbard in a single move. They are reaching remote areas by hitchhiking in the treads of people’s shoes, from being used as bait for fishing and in imported soils for gardening. As the Arctic warms, they are able to colonise more areas.
Early research indicates that the earthworms could have the same effect on Arctic plant productivity as a 3C rise in temperature.

The oil industry is on the cusp of a process of almost total decimation that will begin over the next 30 years, and continue through to the next century. That’s the stark implication of a new forecast by a team of energy analysts led by a former US government energy advisor, seen exclusively by Motherboard.
2020, the forecast suggests, will go down in history as the final point-of-no-return for the global oil industry—a date to which we will look back and remember how the production of oil, as well as other fossil fuels like gas and coal, underwent a slow, but inexorable and largely irreversible decline.
Along the way, some 80 percent of the industry as we know it is going to be wiped out.
Of course, the COVID-19 pandemic is likely to be recognized as a principal trigger for this decline. The new era of oscillating social distancing rules and remote working has crushed once rocketing demand, at least temporarily.
But in reality, the broad contours of this decline were already set in motion even before the pandemic hit. And the implications are stark: we are in the midst of a fundamental energy transition which will see the bulk of the fossil fuel industry gradually eclipsed in coming decades.

RENEWABLE ENERGY: Study: Black turbine blades reduced bird mortality by 72% -- Tuesday, August 25, 2020 -- www.eenews.net
https://www.eenews.net/stories/1063712423

Bird death from turbine collisions dropped by 71.9% where a turbine blade was black, compared with unpainted turbines at the same wind farm, according to findings published last month in the peer-reviewed journal Ecology and Evolution.

Is it not our most indispensable duty to bring down any government that entertains such radical evil, as to destroy this beautiful world in exchange for a few more years of accumulating bits of paper with numbers written on them?
This is a manual on how we are going to do it. Come what may.

Beyond Politics' twin tasks are

1). removing the government and
2). replacing government with citizens assemblies.

Here is outlined everything that Beyond Politics people (BPers, pronounced beepers) need to know.
Now, humankind is facing its final moment of reckoning: ecological and climate collapse. Are we going to stand by and allow the fuckers in control of this world to take us to oblivion or a hell of endless pain, for their own pleasures? or, are we going to come together and say, we are the people and we will not be denied?

Population panic lets rich people off the hook for the climate crisis they are fuelling | Population | The Guardian
https://www.theguardian.com/...20/aug/26/panic-overpopulation-climate-crisis-consumption-environment

The formula for calculating people’s environmental footprint is simple, but widely misunderstood: Impact = Population x Affluence x Technology (I = PAT). The global rate of consumption growth, before the pandemic, was 3% a year. Population growth is 1%. Some people assume this means that the rise in population bears one-third of the responsibility for increased consumption. But population growth is overwhelmingly concentrated among the world’s poorest people, who have scarcely any A or T to multiply their P. The extra resource use and greenhouse gas emissions caused by a rising human population are a tiny fraction of the impact of consumption growth.
