But are we anywhere in that 26 million year range now?

The mass extinction going on now has a different cause.

otter critters and plants that just want a place to live. But I was disappointed that the article did not tell us where we were in this cycle. I want to know if my next 40 years are safe from comets and stuff.

shit by another name.

The coral reefs are all dying.

I worry about if we are going to lose fish as a source of protein. I used to wonder why we could get to the moon but not explore the deep oceans. Maybe that is a good thing since we seem to do so much damage to the places we conquer.

The idea of a 26 million year cycle has been around since the 1980s, and you can find a fair amount on it by googling. All that's changed now is that they seem to have found more evidence to support what's previously been a controversial idea.

Now, we just have to worry about the random one coming from behind the sun.

Do we still have those two satellites, one of which was supposed to sense objects behind the sun?

13 million years, if the dinosaurs were wiped out 65 million years ago.

New evidence that cosmic impact caused Younger Dryas extinctions


(Phys.org) —A period of rapid, intense cooling, known as the Younger Dryas, took place about 13,000 years ago. Scientists think this sudden change in climate caused the extinction of many large mammals, such as the mammoth, and was the reason for the disappearance of North America's Clovis people. According to one hypothesis, a cosmic impact caused the climate to cool. Using data from the Greenland ice core, Michail Petaev and his colleagues at Harvard University have found what appears to be evidence of this impact. Their research appears in the Proceedings of the National Academy of Sciences.

Measurements of oxygen isotopes in the Greenland ice core show that around 13,000 years ago an episode of rapid cooling, which lasted only about 1,000 years, occurred. During this time, many megafauna became extinct and evidence of the Clovis people, one of the earliest human societies to inhabit the Americas, disappeared from the archeological record.
According to one hypothesis, a cometary airburst triggered massive wildfires, which caused the climate to cool. Many scientists have rejected this hypothesis, citing lack of sufficient evidence, in favor of others. The most widely accepted one says that during the deglaciation process, fresh water from the proglacial lake Agassiz discharged into the Arctic Ocean, altering ocean currents.
