The Pine Island Glacier is about to calve another monster iceberg
This is doubly worrisome on the heels of the recent UN climate change report, which gave humanity an urgent deadline to cut carbon emissions: just 12 years.
- It's the same glacier that calved in September 2017, losing an iceberg 4.5 times the size of Manhattan.
- The size of this one, however, is about 15% bigger than the last. It's the sixth large-calving event from this glacier since 2001.
- The irreversible collapse of the West Antarctic ice sheet would raise sea levels 20 feet, says the UN.

The area of the iceberg poised to calve off the Pine Island Glacier is about 115 square miles, or 300 square kilometers.
About one year ago, in Antarctica, the Pine Island Glacier calved an iceberg about 100 sq. miles in size—4.5x the size of Manhattan.
It's about to do it again—and this one is 15% bigger than the last, at 115 square miles.
"As the planet warms from 1.5°C to 2°C, the risks grow rapidly for some very dangerous tipping points, including the irreversible collapse of the West Antarctic ice sheet (which would raise sea levels 20 feet)," reads the UN's recent IPCC Report.
It's doubly (trebly?!) worrisome on the heels of the above UN IPCC report, which basically tells us we're screwed unless we take drastic action—and, I mean drastic—in order to curb emissions and slow the inexorable drift into an Earth that looks like one of those terrifying science fiction novels.

If the West Antarctic ice sheet collapses, it will mean a 20-foot rise in sea levels. And it will release twice as much carbon into the atmosphere as exists today.
The fact that the United States has gone the opposite direction, abandoning the Paris Accord and even calculating a rise of 7 degrees (F) as acceptable and even inevitable when working on new automobile emission standards is contributing to a looming climate change catastrophe by 2040.

We take fewer mental pictures per second.
- Recent memories run in our brains like sped-up old movies.
- In childhood, we capture images in our memory much more quickly.
- The complexities of grownup neural pathways are no match for the direct routes of young brains.
It's not just a case of "what doesn't kill you makes you stronger."
- A new study suggests children who endure trauma grow up to be adults with more empathy than others.
- The effect is not universal, however. Only one kind of empathy was greatly effected.
- The study may lead to further investigations into how people cope with trauma and lead to new ways to help victims bounce back.
It's one of the most consistent patterns in the unviverse. What causes it?
- Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
- Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
- Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
