Did asteroid collision trigger Earth’s abrupt cooling 12,800 years ago?
Why did Earth’s climate rapidly cool 12,800 years ago? New evidence suggests that a comet or asteroid collision is to blame, with support coming from the bottom of a South Carolina lake. Source: https://earthsky.org/earth/asteroid-comet-younger-dryas-abrupt-cooling…

Ask Slashdot: Could Climate Change Be Solved By Manipulating Photons in Space?
Slashdot reader dryriver writes:
Most “solutions” to climate change center on reducing greenhouse gas emissions on Earth and using renewable energy where possible. What if you could work a bit closer to the root of the problem, by thinking about the problem as an excess number of photons traveling from the Sun to the Earth? Would it be completely physically impossible to…
Did an asteroid collision cause an ice age on Earth?
Could a collision between 2 asteroids millions of miles away cause an ice age on Earth, some 460 million years ago? A new study of earthly rocks and sediments – plus micrometeorites that fell in Antarctica – suggest it’s possible.
