When a Mega-Tsunami Drowned Mars, This Spot May Have Been Ground Zero

A new study, published last month in the Journal of Geophysical Research: Planets, suggests that a 75-mile-wide impact scar in the Martian northern lowlands is to the red planet what the Chicxulub crater is to Earth: the mark of a meteor that generated a mega-tsunami when the planet was relatively young. If accurate, the finding adds evidence to the hypothesis that Mars once had an ocean, and would have implications for our search for life there.

Greenland is melting in a heatwave

Greenland is home to the world’s second-largest ice sheet. And when it melts significantly — as it is expected to do this year — there are knock-on effects for sea levels and weather across the globe.

Greenland’s ice sheet usually melts during the summer. This year, it started melting earlier, in May, and this week’s heatwave is expected to accelerate the melt.  https://wqad.com/2019/07/31/greenland-is-melting-in-a-heatwave-thats-everyones-problem/

Permafrost thaw sparks fear of 'gold rush' for mammoth ivory

Melting permafrost from global heating has made it easier for locals to retrieve the remains of woolly mammoths, which have been extinct for thousands of years, and sell them on to China, where the ivory is fashioned into jewellery, trinkets, knives, and other decorations. https://www.theguardian.com/world/2019/jul/14/permafrost-thaw-sparks-fear-of-mammoth-ivory-gold-rush-in-russia#img-1

What to do with oil boom’s wastewater?

“Generally, you’ll find produced water is blacker and has a lot of hydrocarbons in it, so we should not drink it,” said the New Mexico State University educator, who has studied the issue of wastewater treatment for years.

Just what to do with produced water — a byproduct of oil and gas production that may consist of salt, oil, grease, naturally radioactive materials and other toxins — is an increasingly vexing question for both environmentalists and the oil and gas industry.https://www.santafenewmexican.com/news/local_news/what-to-do-with-oil-boom-s-wastewater/article_ebea88d6-ba9d-5e3d-a3eb-0734377fa161.html
