Gotta wear shades.

 

And a gas mask.

For the first time on record, precipitation on Saturday at the summit of Greenland — roughly two miles above sea level — fell as rain and not snow.

Sucks ^^^

 

We have a valley filled with smoke again. I've never seen Vegas like this. Air quality is very bad. Unfortunately I think this is how it's going to be.

Potential for catastrophic collapse of Antarctic "doomsday" glacier with a possible two foot rise in eustatic sea levels, conservatively.

Tangentially related: this had been hypothesized to be the event that triggered the Younger Dryas cooling which led to the demise of Clovis culture. The new paper dates the impact as much too old to be responsible.

It’s 70 degrees warmer than normal in eastern Antarctica. Scientists are flabbergasted.

 

‘This event is completely unprecedented and upended our expectations about the Antarctic climate system,’ one expert said

The Glenzer-Conger ice shelf in Eastern Antarctica has collapsed. The area of the continent was thought to be stable from the effects of climate change, and it holds/held back an ice field that portends a catastrophic eustatic rise in sea level.

Cousin It, what are your thoughts on water for the west part of the US over the next 20-50 years? The articles I find are either sourced by local government officials who say they are tackling the problem or alarmist writing that's usually built off half truths. Vegas is a good example. We use a very small fraction of the water coming from Lake Mead (Colorado River) but that's often ignored altogether for sensational headlines. NV, CA, AZ etc. most certainly have water issues going forward, but I'd like to find writings by scientists who spend their lives studying this stuff.

That is a complicated question that I can’t answer. We know that increasing temps will weaken the jet stream which will cause more extreme winter events, but it should also strengthen el niño which will strengthen the jet stream. Will the two cancel each other??? It’ll probably create other problem.

A real problem for the western US is that the water supply is generated by the previous year's snow pack, and with increasing temps, more of the precipitation will fall as rain, so it’ll immediately run off. If I’m remembering right, the predictions are for a drier west and Midwest, so eventually California will no longer be able to produce our winter vegetables.

Science Alert is a pretty good website to keep up to date on the latest topics, and you can filter it by subject.

Without digging too deep into data, just looking out my window at the world, it seems like all the warnings we've heard over the last 20-30 years are now here.  Looks bleak...not gonna lie. 

[Its Cousin]

You can’t really tie any single event to climate change, but when it is one extreme after another , year after year, the totality of it is apparent.

Looking at past climate shifts and it’s effects on the biosphere, it looks real fucking bleak. Probably a lot worse than what is typically reported.

[Its Cousin]

Looks like we're leaving the La Nina oscillation and heading into an El Nino event later this year and into next. Going to be some fucked up weather coming next fall and winter.
