Grreta Thunberg's Speech to World Leaders at UN

bcglorf says...

@newtboy,

"Stupid to use all these differing sets, that only adds confusion to an already technical and confusing topic."

I'm just glad they stick to metric, with sea level rise you don't even get that .

"No matter what, it's incontrovertible that every iteration of the IPCC reports has drastically raised their damage estimates (temp, sea level) and sped up the timetable from the previous report."

At least temperature wise the AR1 report had higher temperatures, and definitely higher worst case projection scenarios for temp than the latest. I can't say I checked their sea level projections, though typically they're other projections have followed on using their temps as the baseline for the other stuff and thus they track together. That is to say, if you can point me a source that reliably claims otherwise I might go check, but currently what I have checked tells me otherwise.

"I'll take the less conservative NOAA estimates and go farther to assume they over estimate humanity and underestimate feedback loops and unknowns and believe we are bound to make it worse than they imagine."

Which is fine, I only object if that gets characterized as the factually scientific 'right' approach.

"The NOAA .83C number was compared to average annual global temperatures 1901-2000...and oddly enough is lower than 2017's measurements."

Which is yet another source and calibration period from what I found. The 1901-2000 very, very roughly speaking can be thought of as centered on 1950, so in that fuzzy feeling sense not surprising it's 0C is colder than the IPCC centered on the nineties.

The source on current instrumental I went against is below:

As for 2018 being cooler than 2017, that's pretty normal. 1996/1997 were the hottest years on record for a pretty long time before things swung back up. It's entirely possible we stay below the recent high years for another bunch of years before continuing to creep up. Same as a particularly cold day isn't 'evidence', the decadal and even century averages are where the signal comes out of the noise.

They're Made Out of Meat

BSR says...

Not only that. It sounds as if they are trying to figure out a way to beat the meat.

Fun Fact: We smell like steak when we burn.

Space may be a giant airless vacuum, but astronauts swear that it has an odor. Those who have sniffed the aroma liken it to burning metal, steak, and welding, among other peculiar olfactory memories. "Space has its own unique smell," NASA astronaut Scott Kelly said in PBS' Year in Space documentary.

Neil Armstrong's last words on the moon. "Good luck Mr. Gorsky"


It seems when Apollo Mission Astronaut, Neil Armstrong first walked on the moon, he not only gave his famous "One Small Step for Man, One Giant Leap for Mankind" statement, but followed it by several remarks - usual com traffic between him, the other astronauts and Mission Control.

Before he reentered the lander, he made the enigmatic remark, "Good luck, Mr. Gorsky." Many people at NASA thought it was a casual remark concerning some rival Soviet Cosmonaut, however, upon checking, there was no Gorsky in either the Russian nor American space programs.

Over the years many people have questioned him as to what the "Good luck, Mr. Gorsky" statement meant. A few months ago, (July 5th, 1995, Tampa Bay FL) while answering questions following a speech, a reporter brought up the 26 year old question to Armstrong. He finally responded. It seems that Mr. Gorsky had finally died and so Neil Armstrong felt he could answer the question.

When he was a kid, he was playing baseball with his brother in the backyard. His brother hit a fly ball which landed in front of his neighbors' bedroom window. His neighbors were Mr and Mrs. Gorksy. As he leaned down to pick it up, he heard Mrs. Gorsky shouting at Mr. Gorsky. "Oral sex, oral sex you want? You'll get oral sex when the kid next door walks on the moon!"

BOSE? Bose-Einstein condensate

https://www.jpl.nasa.gov/edu/news/2016/7/27/they-really-do-exist-nasas-ghostbusters/

In a team of professional ghost busters, Anita Sengupta would most certainly be the enthusiastic and multi-talented leader. She’s already taken on roles developing launch vehicles, the parachute that famously helped land the Mars rover Curiosity, and deep-space propulsion systems for missions to comets and asteroids.


Sengupta and other members of the entry, descent and landing team for NASA's Mars rover Curiosity discuss the nail-biting details of the August 2012 landing.

Most recently, she’s carved out a niche as the project manager for an atomic physics mission, called the Cold Atom Laboratory, or CAL.

Since the mission was proposed in 2012, Sengupta has been leading a team of engineers and atomic physicists in developing an instrument that can see the unseen. Their mission is to create an ultra-cold quantum gas called a Bose-Einstein condensate, which is a state of matter that forms only at just above absolute zero. At such low temperatures, matter takes on unique properties that seemingly defy the laws of thermodynamics.
