British Politicians and Former Diplomats Are Furious That Trump ‘Bullied’ Their Ambassador Out of Office

864087794’British politicians and officials have reacted with outrage to the resignation of their ambassador to the U.S. amid a rift with President Trump over leaked diplomatic cables, with many accusing the President of bullying their government.

The leak on July 7 of classified memos written by Kim Darroch to the U.K. government, in which he called the Trump Administration “inept” and “incompetent”, triggered a slew of personal insults from the President. Trump tweeted that Darroch was “a very stupid guy” and “a pompous fool.” He also disinvited him from an official dinner July 8, saying “We will no longer deal with him.”…’

‘Completely Terrifying’: Study Warns Carbon-Saturated Oceans Headed Toward Tipping Point That Could Unleash Mass Extinction Event

Ocean 6’The continuous accumulation of carbon dioxide in the planet’s oceans—which shows no sign of stopping due to humanity’s relentless consumption of fossil fuels—is likely to trigger a chemical reaction in Earth’s carbon cycle similar to those which happened just before mass extinction events, according to a new study.

MIT geophysics professor Daniel Rothman released new data on Monday showing that carbon levels today could be fast approaching a tipping point threshold that could trigger extreme ocean acidification similar to the kind that contributed to the Permian–Triassic mass extinction that occurred about 250 million years ago. 

Rothman’s new research comes two years after he predicted that a mass extinction event could take place at the end of this century. Since 2017, he has been working to understand how life on Earth might be wiped out due to increased carbon in the oceans.

“If we push the Earth system too far, then it takes over and determines its own response—past that point there will be little we can do about it.”
—Timothy Lenton, University of Exeter
Rothman created a model in which he simulated adding carbon dioxide to oceans, finding that when the gas was added to an already-stable marine environment, only temporary acidification occurred.

When he continuously pumped carbon into the oceans, however, as humans have been doing at greater and greater levels since the late 18th century, the ocean model eventually reached a threshold which triggered what MIT called “a cascade of chemical feedbacks,” or “excitation,” causing extreme acidification and worsening the warming effects of the originally-added carbon.…’
