Global Warming

[Neferti]

How about somebody starts an IS THERE A GOD thread ... it would attract as much attention as this one .... and never be able to be proved inconclusively.

Never ending argument.

The proof is that the last 17 years warming has stopped.
The trend is flat when the AGW hypothesis would dictate a parabolic rise.

You can pull up every 5-7 year old article you wish - they have been proven wrong with more recent data

It's not rocket science ...but it is statistics.

Bugger, I missed it was 5 years old.

I guess we will agree to disagree until some real new data is available.

I shall let this thread drift into the sand of PA history to resurrected when the real truth emerges.

I would like to see the scared weird little people explain why both poles are still melting if “global warming has stopped.”

AGW hasn’t stopped, of course but the SWL people say it has, so they should be able to explain the conundrum.

The real data is available. You just refuse to accept it because it doesn't conform to your new religion.

Here you go SN something else to chew on.

Monk craps on about Arctic and Antarctic ice melting... but it aint necessarily so.
Both poles do tend to melt in "Summer"... But a characteristic over the past decades has been less ice at the North and more ice in the South, even to the extent of the weight of the ice in the south causing it to break free from the polar region.

2000-year record

This view is supported by the second study published in Nature Geoscience led by Professor Eric Steig at the University of Washington.

His team, which included Dr Ailie Gallant, from Monash University, analysed a new ice core from the West Antarctic Ice Sheet Divide that goes back 2000 years, along with a number of ice cores dating back 200 years.

The divide is the highest point on the West Antarctic Ice Sheet and marks the division where ice "flows" toward either the Weddell or Ross seas.

Gallant says their work focused on the isotope, oxygen 18; higher levels of oxygen 18 indicate higher air temperatures.

She says while they discovered large increases in temperatures during the 1990s, there were several decades that exhibited similar climate patterns in the past 200 years.

"Then when we looked over 2000 years, there were a few other blips in about 1 per cent of the record," says Gallant.

"What this tells us is that what we saw in the 1990s is very unusual but not necessarily unprecedented."

Steig says while recent changes in climate and ice thinning are dramatic in the West Antarctic Ice Sheet, they cannot be attributed with confidence to human-induced global warming.

But the same is not true for the Antarctic Peninsula where rapid ice loss is even more dramatic, he adds.

The research shows the West Antarctic climate of the 1940s and 1830s would be similar to modern conditions. Along with the 1990s, these decades were also periods of unusual El Niño activity.

Gallant says their research suggests these decadal variations in temperature are linked to wind circulation patterns in the tropical Pacific Ocean and sea surface temperatures.

She says the study highlights the need to better understand how tropical Pacific climate will change in the future as it will influence what happens to the West Antarctic Ice Sheet.

No, the Antarctica is losing net ice, not nearly as fast as the Arctic but losing ice nevertheless.

Wassup?
Can't read?

Want me to post it in a bigger font for you or are you happy for others to just read it and know you are a moron?

let me know when you get the point.

Having read lots of conflicting reports over the years some that are written by the same people and conflict just about every month... lends itself to the FACT that they are still learning or just making it up as they go.

But the above article refines the work of one group that has been studying at close quarters what is actually happening.

The following is a report based on data from a group at the South Pole who used a very different method to get first hand data...

Antarctic ice shelves not melting at all, new field data show
Posted in Science, 25th June 2012 07:19 GMT

Twenty-year-old models which have suggested serious ice loss in the eastern Antarctic have been compared with reality for the first time - and found to be wrong, so much so that it now appears that no ice is being lost at all.

"Previous ocean models ... have predicted temperatures and melt rates that are too high, suggesting a significant mass loss in this region that is actually not taking place," says Tore Hattermann of the Norwegian Polar Institute, member of a team which has obtained two years' worth of direct measurements below the massive Fimbul Ice Shelf in eastern Antarctica - the first ever to be taken.

According to a statement from the American Geophysical Union, announcing the new research:

It turns out that past studies, which were based on computer models without any direct data for comparison or guidance, overestimate the water temperatures and extent of melting beneath the Fimbul Ice Shelf. This has led to the misconception, Hattermann said, that the ice shelf is losing mass at a faster rate than it is gaining mass, leading to an overall loss of mass.

The team’s results show that water temperatures are far lower than computer models predicted ...

Hatterman and his colleagues, using 12 tons of hot-water drilling equipment, bored three holes more than 200m deep through the Fimbul Shelf, which spans an area roughly twice the size of New Jersey. The location of each hole was cunningly chosen so that the various pathways by which water moves beneath the ice shelf could be observed, and instruments were lowered down.

The boffins also supplemented their data craftily by harvesting info from a biology project, the Marine Mammal Exploration of the Oceans Pole to Pole (MEOP) effort, which had seen sensor packages attached to elephant seals.

"Nobody was expecting that the MEOP seals from Bouvetoya would swim straight to the Antarctic and stay along the Fimbul Ice Shelf for the entire winter," Hattermann says. "But this behaviour certainly provided an impressive and unique data set."

Normally, getting sea temperature readings along the shelf in winter would be dangerous if not impossible due to shifting pack ice - but the seals were perfectly at home among the grinding floes.

Overall, according to the team, their field data shows "steady state mass balance" on the eastern Antarctic coasts - ie, that no ice is being lost from the massive shelves there. The research is published in the journal Geophysical Research Letters.

This is good news indeed, as some had thought that huge amounts of ice were melting from the region, which might mean accelerated rates of sea level rise in future.
