Mystery mechanism drove global warming 55 million years ago

A runaway spurt of global warming 55 million years ago turned Earth into a hothouse but how this happened remains worryingly unclear, scientists said on Monday.
Previous research into this period, called the Palaeocene-Eocene Thermal Maximum, or PETM, estimates the planet's surface temperature blasted upwards by between five and nine degrees Celsius (nine and 16.2 degrees Fahrenheit) in just a few thousand years.

The Arctic Ocean warmed to 23 C (73 F), or about the temperature of a lukewarm bath.

How PETM happened is unclear but climatologists are eager to find out, as this could shed light on aspects of global warming today.

What seems clear is that a huge amount of heat-trapping "greenhouse" gases -- natural, as opposed to man-made -- were disgorged in a very short time.

The theorised sources include volcanic activity and the sudden release of methane hydrates in the ocean.

A trio of Earth scientists, led by Richard Zeebe of the University of Hawaii, try to account for the carbon that was spewed out during PETM.

They believe that levels of atmospheric carbon dioxide (CO2) rose by 70 percent during PETM's main phase to reach 1,700 parts per million (ppm), attaining a concentration of between four and five times that of today.

But all this CO2 can only account for between one and 3.5 C (1.8-6.3 F) of PETM's warming if the models for climate sensitivity are right, the team found.

There must have been some other factor that stoked temperatures higher.

Even though there are big differences between Earth's geology and ice cover then and now, the findings are relevant as they highlight the risk of hidden mechanisms that add dramatically to warming, says the paper.

Some of these so-called "positive feedbacks" are already known.

For instance, when a patch of Arctic sea ice melts, this exposes the uncovered sea to sunlight, depriving it of a bright, reflective layer.

That causes the sea to warm, which leads to the loss of more ice, which in turn helps the sea to warm, and so on.

But these "feedbacks" are poorly understood and some scientists believe there could be others still to be identified.

"Our results imply a fundamental gap in our understanding about the amplitude of global warming associated with large and abrupt climate perturbations," warns Zeebe's team.

"This gap needs to be filled to confidently predict future climate change."

After the big warm-up, the planet eventually cooled around 100,000 years later, but not before there had been a mass extinction, paving the way to the biodiversity that is familiar to us today.

Man-made global warming, driven mainly by the burning of oil, gas and coal, has amounted to around 0.8 C (1.12 F) over the past century.

Last week in L'Aquila, Italy, the Group of Eight (G8) industrialised countries and other economies that together account for 80 percent of greenhouse-gas emissions pledged to try to limit overall warming to 2 C (3.6 F) over pre-industrial times.

It's too bad most scientists that are competent are busy doing science stuff..."Hollywood" scientists have done alot of fucking harm to the ignorant public.

This can all be tied to Man's own arrogance. I suspect they will figure out a way to blame people for this, because when there is something greater than us and we can't wrap our minds around it, then it has to be our fault, right algore?

Follow the money.

A lot of these scientists don't have real jobs and need the research money that will flow as long as the global warming BS continues. And al gore stands to profit if the carbon trading system takes off. It's all self serving.

my thoughts

Gee, news flash, we don't understand climate change yet we think it can be controlled by what we do? Spend resources to adapt to climate change, not trying to control it.

Since the end of the last ice age, beginning 18,000 years ago, the Earth’s temperature has risen 16 degrees and, correspondingly, sea levels have risen approximately 300 feet. According to the eco-freaks/Communists the first 299.5 feet of sea level increase is good, sweet, clean Mother Nature - but the last 6 inches (the amount being attributed to man since the advent of the Industrial Revolution) is a call to action to drastically reenvision the socioeconomic systems that under-gird the entire developed world.

Using fear tactics (the fear of climate change) to affect political change is necessary when the truth is inconvenient and the motives are ulterior.

The laughable ‘science’ behind this eco-drivel and the sheer banality of the propaganda machine that spews this message of ‘change’ 24 hours a day is simply stunning. It’s like a call to prayer to the faithful. How anyone with more than two firing neurons can buy into this shit is beyond me.

Hopefully this won't pass. This will fuck everything up worse than the h1n1 they're about to slang around.

Our government needs our help, they have an addiction. Our government is addicted to our money. Since they always have our best interest at heart it's time we return the favor. We need to have an intervention, for the governments own good of course. It's just irresponsible for us to let people with a known money addiction continue to handle our money. Lets have an intervention now so we can help these sick individuals.
