The global cooling could also have been caused by a large volcanic eruption pouring ash into the sky and it could have left the large crator also. So I don't see that this is solid proof that it must have been caused by an asteroid strike.
Most recently, the 1991 explosion of Mount Pinatubo, a stratovolcano in the Philippines, cooled global temperatures for about 2–3 years.
The climate is changing, but it's not changing the way the climate change crowd predicted it would. Nature has made a mockery of global warming, so who are the real climate deniers?
