Did a #Cosmic #Impact 12,000 Years Ago Create the Younger Dryas #Catastrophe? Hiawatha Crater Greenland
#Bright #Insight
"NASA recently discovered a #massive, 19-mile (31km) wide #crater, found hidden underneath #Greenland’s Hiawatha Glacier.
This crater is the result of an asteroid impact, from a nearly 1 mile-wide mountain of iron, weighing somewhere around, get this, 11-12 BILLION tons, and was traveling at approximately 12 miles per second - which is equivalent to more than 43,000 miles per hour - when it slammed into the earth some 12,000 years ago – And…with the mind-boggling force of essentially a 700-megaton bomb. Is this evidence to support the Younger Dryas impact hypothesis?

#Discovered in #Greenland in the late 1890's, #hackmanite is named for Finnish geologist Victor Hackman. It is a rare occurrence to find gem-grade hackmanite; at best, most crystals are translucent. Hackmanite is the light pink to pale violet variety of sodalite. It is a particularly unusual gem because it exhibits a special optical property known as "tenebrescence," a type of reversible photochromism. This feature allows the gems to temporarily change color when exposed to different light forms. While hackmanite gems are usually pink to violet, the color quickly fades to gray or greenish-white in sunlight, and will slowly return to the original color after changing the light. Its tenebrescent property makes hackmanite a prized mineral for collectors.
Countries of Origin
Canada; Myanmar; Afghanistan; Russian Federation; Unknown; Guinea; Norway; United States of America; Greenland
Care
When exposed to sunlight the color will fade to white. Color will return if stones are stored in darkness for several days or when exposed to shortwave ultraviolet light.

World on brink of five ‘disastrous’ climate tipping points, study finds
The Guardian
Giant ice sheets, ocean currents and permafrost regions may already have passed point of irreversible change.
The climate crisis has driven the world to the brink of multiple “disastrous” tipping points, according to a major study.
It shows five dangerous tipping points may already have been passed due to the 1.1C of global heating caused by humanity to date.
These include the collapse of Greenland’s ice cap, eventually producing a huge sea level rise, the collapse of a key current in the north Atlantic, disrupting rain upon which billions of people depend for food, and an abrupt melting of carbon-rich permafrost.
At 1.5C of heating, the minimum rise now expected, four of the five tipping points move from being possible to likely, the analysis said. Also at 1.5C, an additional five tipping points become possible, including changes to vast northern forests and the loss of almost all mountain glaciers.
In total, the researchers found evidence for 16 tipping points, with the final six requiring global heating of at least 2C to be triggered, according to the scientists’ estimations. The tipping points would take effect on timescales varying from a few years to centuries. (...)
“The study really underpins why the Paris agreement goal of 1.5C is so important and must be fought for.
“We’re not saying that, because we’re probably going to hit some tipping points, everything is lost and it’s game over. Every fraction of a degree that we stop beyond 1.5C reduces the likelihood of hitting more tipping points.” (...)
“Our new work provides compelling evidence that the world must radically accelerate decarbonising the economy. To achieve that, we need to trigger positive social tipping points.”

Greenland ice sheet has passed the point of no return and "irreversibly committed to retreat by at least 59,000 square kilometers (22,780 square miles), an area considerably larger than Denmark" and at least 10 inches of sea level rise
A study published Aug. 29, 2022, demonstrates – for the first time – that Greenland’s ice sheet is now so out of balance with prevailing Arctic climate that it no longer can sustain its current size. It is irreversibly committed to retreat by at least 59,000 square kilometers (22,780 square miles), an area considerably larger than Denmark, Greenland’s protectorate state.
Even if all the greenhouse gas emissions driving global warming ceased today, we find that Greenland’s ice loss under current temperatures will raise global sea level by at least 10.8 inches (27.4 centimeters). That’s more than current models forecast, and it’s a highly conservative estimate. If every year were like 2012, when Greenland experienced a heat wave, that irreversible commitment to sea level rise would triple. That’s an ominous portent given that these are climate conditions we have already seen, not a hypothetical future scenario.

The most interesting weather analysis I've seen in quite some time.
Greenland GAINED ice in AUGUST. Think about that.

Freeze frames: the epic wilderness of Greenland – in pictures | Art and design | The Guardian
From Inuit hunters to the vast expanses of snow and ice, Danish photographer Carsten Egevang’s images spring from a three-decade fascination with the planet’s least-populated country
Sometimes, black and white photography seems to be the best means of highlighting the extremes of life in the Arctic.
