Governments around the world are preparing for what is to come. Are you?
Researchers from the International Ocean Discovery Program and the University of Texas in Austin found in 2016 that asteroid dust matching a core sample taken from the Chicxulub impact crater is one of the same. The discovery yields proof the dinosaurs went extinct after a deep impact caused dust to blanket the Earth’s atmosphere triggering a ‘dark winter’ scenario.
Researchers admit the element iridium is the nail in the coffin and seals the case on what once was an open debate. A 3000-mile long core sample taken from the seafloor confirms the match.
“The telltale sign of asteroid dust is the element iridium – which is rare in the Earth’s crust, but present at elevated levels in certain types of asteroids,” UT News reports. “An iridium spike in the geologic layer found all over the world is how the asteroid hypothesis was born.”
“In the new study, researchers found a similar spike in a section of rock pulled from the crater,” the university report affirms. “In the crater, the sediment layer deposited in the days to years after the strike is so thick that scientists were able to precisely date the dust to a mere two decades after impact.”
“The circle is now finally complete,” Vrije Universiteit Brussel geochemistry professor and leader of the Science Advances study Steven Goderis said. It’s now clear that 75% of life on Earth perished following the ill-disposed meteor strike that triggered blackouts that lasted several decades.
“We combined the results from four independent laboratories around the world to make sure we got this right,” he explained.
It’s also important to point out that large amounts of sulfur were dispersed into the atmosphere. The sulfur is believed to have seeded acid rain exacerbated global cooling, making matters worse.
The findings are particularly alarming because NASA has in recent years cataloged more near-Earth objects than ever before. And there seems to be no end in sight.
It’s just a matter of time until another large boulder from space makes its way down to Earth. And that’s why the U.S. government and other governments around the world have been preparing at breakneck speed.
In fact, asteroid deflection and mitigation plans have already been put into place at a White House level. The 2019 presidential-level publication titled National Near-Earth Object Preparedness Strategy and Action Plan points out ways NASA is planning to mitigate threat-listed objects.
If that’s not enough, asteroids have been a big topic in the news lately. No holds barred headlines like Is this giant asteroid on course to obliterate Earth? An expert weighs in can make one question what’s to come. However, the real question is: are you prepared for disasters from space?
