Several climate models from top institutions around the globe are suddenly predicting the world will warm by 5°C (9°F) by 2100, a possible "nightmare scenario," and scientists aren't sure why, Bloomberg reports.

Why it matters: The 2015 Paris climate agreement set an agreed threshold to attempt to limit warming below 1.5°C (2.7°F). Should these newest projections turn out to be accurate, the Paris agreement's goals would already be well out of reach.

The state of play: These models have projected global warming with relative accuracy for the last half-century, and there has long been a general consensus that warming of 3°C (5.4°F) would produce catastrophic change.

  • Yes, but: Researchers don't yet agree on how to interpret the hotter results — based on supercomputer simulations of climate models — and some believe they may have "overshot."

The bottom line: These models inform how policymakers and politicians can plan for the future effects of climate change, so any unexpected and extreme change in their output would radically lessen the time that humanity would have to prepare.

How GameStop exposed the market

Retail traders have found a cheat code for the stock market, and barring some major action from regulatory authorities or a massive turn in their favored companies, they're going to keep using it to score "tendies" and turn Wall Street on its head.

What's happening: The share prices of companies like GameStop are rocketing higher, based largely on the social media organizing of a 3-million strong group of Redditors who are eagerly piling into companies that big hedge funds are short selling, or betting will fall in price.

Who benefits from Biden's move to reopen ACA enrollment

Nearly 15 million Americans who are currently uninsured are eligible for coverage on the Affordable Care Act marketplaces, and more than half of them would qualify for subsidies, according to a new Kaiser Family Foundation brief.

Why it matters: President Biden is expected to announce today that he'll be reopening the marketplaces for a special enrollment period from Feb. 15 to May 15, but getting a significant number of people to sign up for coverage will likely require targeted outreach.

Big Tech bolts politics

Illustration: Eniola Odetunde/Axios

Big Tech fed politics. Then it bled politics. Now it wants to be dead to politics. 

Why it matters: The social platforms that profited massively on politics and free speech suddenly want a way out — or at least a way to hide until the heat cools.
