A prolonged finger-pull era, so to speak.
By scaling up the digestive wind of cows, British scientists estimate that dinosaurs produced 520 million tons of methane gas per year, as opposed to cows today, which produce something like 50-100 million tons.
Since previous studies indicate that the Earth was up to 10C (18F) warmer during the Mesozoic Era than it is today, the researchers theorize that the gas could have been a key factor in that period of global warming.
“David Wilkinson from Liverpool John Moore’s University, and colleagues from the University of London and the University of Glasgow published their results in the journal Current Biology,” the story continues.
“Methane is known as a “greenhouse gas” that absorbs infrared radiation from the sun, trapping it in the Earth’s atmosphere and leading to increased temperatures.”
Sneaky little bit there, aye? They’re telling us that methane is “known” to lead to increased temperatures. Really? Known by whom?
“With the knowledge that livestock emissions currently contribute a significant part to global methane levels, the researchers used existing data to estimate how sauropods could have affected the climate.”
Like, this is a new story?
I wrote about dinosaur flatulence in Not by Fire but by Ice (p 25), where I said, “you may have seen the article in your local paper touting the thought that massive emissions of methane gas – caused by dinosaur flatulence – may have caused global warming, doing whatever it is that global warming is supposed to do.”
It was a stupid idea then, and it’s a stupid idea now.
As far as I’m concerned it’s simply a back-handed attempt to blame cows – and therefore humans – for a natural cycle.
“Besides,” says this article on hotair.com, “the most well-accepted theories of dinosaur extinction don’t involve climate warming. It’s generally accepted that catastrophic and sudden cooling caused the extinction of dinosaurs and other animal and plant life of that era.”
Ass opposed to the BBC article, this one is fun:
Thanks to Jamal Kilani, Carl Swartz, Gordon, Icewoman, Steven Woodcock, Benao, Benjamin Napier and Peter Lamb for these links.
“The Universities around the world must be producing the worlds best drugs,” says Carl.” Surely they can not all be that stupid.”
“More foolishness from so-called scientists,” says Benjamin
“So pathetic,” says Jamal.
