The largest climate change in central North America since the age of the dinosaurs 65 million years ago, a temperature drop of nearly 15 degrees Fahrenheit, is documented within the fossilized teeth of horses and other plant-eating mammals, a new study reveals.

I may not read all the responses, I do read the original article however.
ha ha.....super well done...
Guess they couldn't spell psychrometer, or used the term barometer to mean measurement.
I'd wager that your average local dentist or orthodontist is making a lot more than your average paleontologist, with fewer educational expenses.
Yeah, your average dentist/orthodontist doesn't have to "dig up" his patients.
Massive climate change in the earth's history has been a well known fact for decades. That knowledge hasn't figured in the climate change debate and this bit of knowledge (which only reinforces previous knowledge and doesn't break new ground except as it relates to gathering the same info in different way) won't change anything.
What US "journalists" - educated in advocacy journalism at our universities - know, is that 80 - 90% of the people will read:
"Largest North America Climate Change In 65 Million Years, Study Shows" and then read no further.
The format of the title was chosen because the title fits the "humans cause global warming" agenda, whether the information in the article is relevant to that or not.
If the editors really wanted to convey the true meaning of what the article is about, they would have said:
"Largest North America Climate Change Was 34 Million Years Ago, Study Shows".
But, that would have been factual and not tied to any editorial agenda. That is not what "journalism" is for.
Did any of you consider reading (and understanding) the article, before posting?
Yes, but what fun is there in that?
I'm not instilled with a lot of confidence in a Science website that takes ten minutes to load on my browser. I know I'm a dinosaur to have a 28.8 kpb dial-up (nothing else is available here) but I've downloaded YouTube videos in less time. How up on science can they be?
Brownie points for you on this one.
So the previous record 65 million years ago, was that due to SUVs?
Was it aerosol spray cans?
besides it's BS because NO PERSON can prove anything 65 million years ago. Carbon fiber dating is only good factually to 16 thousand years, the rest of the chart is actary assumptions.........
Donald R. Prothero, a professor of geology at Occidental College and an expert on the Eocene-to-Oligocene transition, said, "We have long known that there were some dramatic climatic changes in the earliest Oligocene based on the record of marine plankton and isotopes. But we didn't know how much change there was in degrees, although the plant changes suggested it was indeed about 15 degrees."
The bottom line of the article...dramatic climate changes have occurred tens of millions of years in the past. They don't really know why but they're guessing that changes in ocean currents may have caused it.
Did they try to determine what solar output was at the time? Nothing said in the article.
Where have you been? Global cooling is a sign of global warming! And for those who may be confused by that, simply substitute the term, 'abrupt climate change' for either of the above. Geeze! I thought everybody knew that! :)
Algore. He got lost in the petrified forest.
It came from here, by the way.
They are showing temperatures in Celsius, to convert to Fahrenheit, multiply by 9, divide by 5, then add 32.
Our recent (last 2 million years) temperature fluctuations, can't show on this graph, because the time scale is too great.
Over the last 1.8 million years, the Earth has been locked in a series of ice ages, alternating with interglacial periods. The ice ages are about 5-6 degrees (F) cooler than today's temperatures, and average about 4 times as long as the interglacial periods. (The Earth is currently in an interglacial period.)
The normal average temperature of the Earth is about 10-15 degrees (F) higher than today's.
The whole aim of practical politics is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary. - H. L. Mencken

And "carbon fiber dating" would be what? Determining the age of your fishing rod, maybe?
Did Dan Rather draw that? /s
