Methane Feedback Loop Beyond Humans' Ability to Control May Have Begun—NOAA
Lan said that because the Earth's climate is already warming the methane produced from natural wetlands is only set to increase. This signals the beginning of a feedback loop—an ongoing cycle that cannot be broken.

"From natural processes, we know that wetland methane emissions are sensitive to change in precipitation and temperature," she said. "Methane production from microbes increases with increases in global temperature which is driven by long-term greenhouse gas emissions. More atmospheric methane, in turn, can further warm up the earth. That's the feedback loop we are referring to."
There it is again, that funny feeling.
That funny feeling of humility that the dinosaurs managed to live longer on this planet that us? Yeah, I know that feeling.

World on brink of five ‘disastrous’ climate tipping points, study finds
It shows five dangerous tipping points may already have been passed due to the 1.1C of global heating caused by humanity to date.

These include the collapse of Greenland’s ice cap, eventually producing a huge sea level rise, the collapse of a key current in the north Atlantic, disrupting rain upon which billions of people depend for food, and an abrupt melting of carbon-rich permafrost.

At 1.5C of heating, the minimum rise now expected, four of the five tipping points move from being possible to likely, the analysis said. Also at 1.5C, an additional five tipping points become possible, including changes to vast northern forests and the loss of almost all mountain glaciers.

In total, the researchers found evidence for 16 tipping points, with the final six requiring global heating of at least 2C to be triggered, according to the scientists’ estimations. The tipping points would take effect on timescales varying from a few years to centuries. [...]

Prof Johan Rockström, the director of the Potsdam Institute for Climate Impact Research, who was part of the study team, said: “The world is heading towards 2-3C of global warming.

World heading into ‘uncharted territory of destruction’, says climate report
The world’s chances of avoiding the worst ravages of climate breakdown are diminishing rapidly, as we enter “uncharted territory of destruction” through our failure to cut greenhouse gas emissions and take the actions needed to stave off catastrophe, leading scientists have said.

Despite intensifying warnings in recent years, governments and businesses have not been changing fast enough, according to the United in Science report published on Tuesday. The consequences are already being seen in increasingly extreme weather around the world, and we are in danger of provoking “tipping points” in the climate system that will mean more rapid and in some cases irreversible shifts.

Recent flooding in Pakistan, which the country’s climate minister claimed had covered a third of the country in water, is the latest example of extreme weather that is devastating swathes of the globe. The heatwave across Europe including the UK this summer, prolonged drought in China, a megadrought in the US and near-famine conditions in parts of Africa also reflect increasingly prevalent extremes of weather.

US scientists boost clean power hopes with fusion energy breakthrough | Financial Times
The federal Lawrence Livermore National Laboratory in California, which uses a process called inertial confinement fusion that involves bombarding a tiny pellet of hydrogen plasma with the world's biggest laser, had achieved net energy gain in a fusion experiment in the past two weeks, the people said.
The fusion reaction at the US government facility produced about 2.5 megajoules of energy, which was about 120 per cent of the 2.1 megajoules of energy in the lasers, the people with knowledge of the results said, adding that the data was still being analysed.
The US department of energy has said energy secretary Jennifer Granholm and under-secretary for nuclear security Jill Hruby will announce "a major scientific breakthrough" at the Lawrence Livermore National Laboratory on Tuesday. The department declined to comment further.

Now imagine if all these people liking and cheering for Thunberg owning some clown's ass, would show the same support for her fight to save this godforsaken planet, helping promote her campaigns and speeches.

Alas, we are too busy fighting what we hate to care about saving what we love.
