The Asteroid That Wiped Out Dinosaurs Plunged Earth Into Catastrophic Winter (bbc.com)
The asteroid impact roughly 66 million years ago that wiped out three-quarters of plant and animal species, including the dinosaurs, dropped temperatures globally below freezing for several years. The new assessment, reported in the journal Geographic Research Letters, gives scientists a much clearer picture of the climate catastrophe following the event. BCC reports: The UK geophysicist was the co-lead investigator on the 2016 project to drill into what remains of the impactor's crater under the Gulf of Mexico. She and colleagues spent several weeks retrieving the rock samples that would allow them to reconstruct precisely how the Earth reacted to being punched by a high-velocity space object. Their study suggests the asteroid approached the surface from the north-east, striking what was then a shallow sea at an oblique angle of 60 degrees. Roughly 12km wide and moving at about 18km/s, the stony impactor instantly excavated and vaporized thousands of billions of tonnes of rock. This material included a lot of sulphur-containing minerals such as gypsum and anhydrite, but also carbonates which yielded carbon dioxide. The team's calculations estimate the quantities ejected upwards at high speed into the upper atmosphere included 325 gigatones of sulphur (give or take 130Gt) and perhaps 425Gt of carbon dioxide (plus or minus 160Gt). The CO2 would eventually have a longer-term warming effect, but the release of so much sulphur, combined with soot and dust, would have had an immediate and very severe cooling effect.
Just pump several gigatons of sulphur into the atmosphere to counteract the warming of the carbon dioxide!
What could POSSIBLY go wrong?!

sed -e 's/Chuck Norris/Rajnikant/g' joke > fact
How do we know it wasn't a weaponized asteroid intended to clearing and terraforming this planet for the new human species to evolve and be monitored?
Or roughly 50 billion octaves.
At the bottom of the
There are actually several species of plant that can grow in freezing temperatures.
How many Gt of CO2 and S have we human released into the air, since the industry revolution?
As for CO2: according to Wikipedia, around 380 Gigatonnes of carbon in the 1901-2013 timespan. Or just under 1400 Gigatonnes of CO2. So this meteor strike would have put ~1/3 of the amount of CO2 in the atmosphere in a single event, of what mankind has produced throughout its industrial age.
Note that the source referenced by Wikipedia only seems to have per-year totals (estimates, obviously). So I'm guessing that 380 GtC number was arrived at by adding up the annual figures.
I've done some research of my own. Well, I read back issues of National Geographic:
There was this guy, way back, I think it was before WWII and he flew all by himself to somewhere like in Europe. Maybe it was even further like in France.
Did you know there was a guy he was an actor and he liked killed a President?
You can't keep your eyes open when you sneeze.
You can't touch your nose with your elbow, unless like you are in a car accident, like my friend becky. She's really messed up.
If you hit the earth with a big enough rock it will kill like almost all of the dinosaurs, except like the ones that ended up in Jurassic Park and then because all of the stuff that goes in the air it will be like winter like even in the summer and you can't get a refund from your vacation cause it snowed in Cabo but then like a really long time later like at least a thousand years some guy says that it happened and like he wasn't even the first guy to think of it because like you know the indians that lived when it happened already knew it, but then some other guy like BeauHD puts it on the web like even on Slashdot because even like Reddit wont put it up.
I'm going to watch TMZ now.
. . . could have told you that. Heck. the K/T Event has a distinct signature in any rock column, and its' characterization. . . in the 1980s. . . led to the TTAPS paper, better known as the "Nuclear Winter" paper. This is 35+ year-old "news". . .
As TFS says, "The new assessment gives scientists a much clearer picture of the climate catastrophe following the event."
I'm not sure what your point is? Everyone knows what happened. This is a piece of scientific research. It deepens our understanding of the event a little, adds more data-points, tightens some variables, gets corroborating evidence from a different (more direct) technique.
catastrophe

noun: catastrophe; plural noun: catastrophes
an event causing great and often sudden damage or suffering; a disaster.
Nothing about where the universe is "supposed to go", just damage and suffering.
