Dinosaur-killer Asteroid Triggered a Global Warming [and it lasted 100,000 Years!]
Around 66 million years ago, an asteroid or comet at least 10 kilometers (6 miles) in diameter impacted a few miles from the present-day town of Chicxulub in Mexico (hence it is dubbed as the “Chicxulub impactor”, the “dinosaur-killer”), at around 64,000 kilometers per hour (40,000 mph). The impact has created a crater (Chicxulub crater) …

Soon, the ISS Will Be the Coldest Known Place in the Universe
Where is the coldest known place in the Universe? It may sound strange, but today, it is here on Earth: in 1995, in a laboratory in M.I.T. (Massachusetts Institute of Technology), the German physicist Wolfgang Ketterle and his colleagues have cooled a sodium gas to the lowest temperature ever recorded, only half-a-billionth of a degree …

Most species hold their geographic range if we limit global warming to 1.5°C [new study]
If we limit global warming to 1.5°C rather than 2°C above the pre-industrial levels by the year 2100, the impacts of climate change would be much less dramatic, a new study says. According to the researchers, for vertebrates and plants, the number of species losing more than half their geographic range by 2100 will be …
