Warming Feedback Loop
"Arctic amplification" refers to the fact that the region is warming twice as quickly as the rest of the planet—and as ice warms, exposing more ocean water, the process naturally speeds up.
"Scientists know that the Arctic is warming about twice as fast as the rest of the planet on average, a phenomenon known as Arctic amplification," writes Michael Lemonick. "And they have a pretty good idea of why: warmer temperatures lead to more meltback in sea ice in the summer, which exposes more ocean water. The water, which is darker and less reflective than ice, absorbs energy, heats up and warms the air in turn, leading to even more melting. It's a classic feedback loop, and it makes all sorts of sense"
A federal judge ruled that the Trump administration likely violated the reporter's Fifth Amendment rights when it stripped his press credentials earlier this month.
- Acosta will be allowed to return to the White House on Friday.
- The judge described the ruling as narrow, and didn't rule one way or the other on violations of the First Amendment.
- The case is still open, and the administration may choose to appeal the ruling.
Progressive America would be half as big, but twice as populated as its conservative twin.
- America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
- Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
- Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America
New research identifies an unexpected source for some of earth's water.
- A lot of Earth's water is asteroidal in origin, but some of it may come from dissolved solar nebula gas.
- Our planet hides majority of its water inside: two oceans in the mantle and 4–5 in the core.
- New reason to suspect that water is abundant throughout the universe.
