The whole structure of society needs to change as Kyoto is a band aid of minor proportions! We as buyers force industry to lower prices….hence we buy Chinese or Taiwanese, and these have very poor conditions for greenhouse gases produced as no regulations of real substance. If they get clamped down on by authorities, businesses will just go elsewhere such as India or other areas where a distinct advantage can occur for the company who buys there products to on sell them to the public at lower prices! What was deemed to be fixed….will be relocated to other countries for opportunists to make big $ from! OH WHAT A TANGLED WEB WE LIVE IN! THE CIRCLE TURNS AND COMES BACK AGAIN!

This is info located as at today: A grouping of the world’s top greenhouse gas emitters has backed UN-led efforts to forge a global pact to fight climate change, but disagreed on a sectoral approach to curb emissions from industry. G20 nations ranging from top carbon emitters the United States and China to big developing economies Brazil, Indonesia and South Africa held three days of talks near Tokyo to discuss ways to tackle rapidly rising emissions.

“Contrary to conventional wisdom, many fundamental questions about global warming remain unanswered. Two crucial questions are: 1) Is significant human-induced global warming actually occurring? 2) If it is occurring, will the net effects be beneficial or harmful? In neither case is the answer an unambiguous “yes.”

“First, significant global warming may not be occurring. Certainly, the historical relationship between CO and temperature changes is ambiguous. Although levels of atmospheric CO have risen nearly 40 percent since the turn of the century, data from within the United States indicates no statistically significant increase in mean annual temperatures. In fact, between 1920 and 1987, there was a slight cooling trend. And the region most likely to see temperature increases, the Arctic, has actually cooled since about l940.”
“A warmer climate may increase precipitation and produce more ice and snow in colder areas. This would increase the earth’s albedo and cool the planet.”

QUESTION: Does temperature rise cause CO2 rise or the other way around?
ANSWER: A common misconception is that you can only have one or the other. In actuality, the answer is both.

QUESTION?Milankovitch cycles – how increased temperature causes CO2 rise?
ANSWER: Looking over past climate change, scientists have observed a cycle of ice ages separated by brief warm periods called interglacials. This pattern is due to Milankovitch cycles – gradual, regular changes in the earth’s orbit and axis. While there are several different cycles, the dominant climate signal is the 100,000 year eccentricity cycle as the Earth’s orbit changes from a more circular to a more elliptical orbit (Petit 1999, Shackleton 2000). The eccentricity cycle causes changes in insolation (incoming sunlight). When springtime insolation increases in the southern hemisphere, this coincides with rising temperatures in the south, retreating Antarctic sea ice and melting glaciers in the southern hemisphere (Shemesh 2002). As temperature rises, CO2 also rises but lags the warming by 800 to 1000 years (Monnin 2001, Caillon 2003, Stott 2007).

QUESTION:How does warming cause a rise in atmospheric CO2?
ANSWER:As the oceans warm, the solubility of CO2 in water falls (Martin 2005). This causes the oceans to give up more CO2, emitting it into the atmosphere. The exact mechanism of how the deep ocean gives up its CO2 is not fully understood but believed to be related to vertical ocean mixing (Toggweiler 1999).

As the longest ice core record of Earth’s weather history obtained to date, the core also shows that those gases; chiefly carbon dioxide and methane play a big role in warming the planet when ice ages end.

But how this icy record will influence current theories about global warming blamed on human activity isn’t clear, the researchers said.

“The ice core gives us the past, not the future. But it adds to our thinking about the future, about the future of our climate,” said Jean-Robert Petit, director of research at the National Center for Scientific Research in Grenoble, France. “It’s clear that greenhouse gas levels are unprecedented compared with the previous 400,000 years.”

Coldest spot on Earth: The core was extracted from 1992-98 by a U.S.A. Russian and French team at Russia’s Vostok research station, the coldest spot on Earth. Petit and team members endured readings as cold as minus 70 Fahrenheit (minus 57 Celsius), though the station holds the world record low of minus 129 (minus 89 Celsius). They stopped drilling about 120 yards (109 meters) short of a subterranean lake the size of Lake Ontario that’s been trapped for perhaps millions of years beneath the ice sheet. Scientists want to send sterilized robots to explore the pristine lake and are protecting it from contamination until then.

Each cylinder like chunk of ice drilled out of the ice sheet contains a record of snowfall, atmospheric chemicals, temperature conditions, dust and bubbles of air. Those clues, trapped in icy layers like tree rings, enable scientists to reconstruct past climates.

The lengthy Vostok ice core is particularly significant because previous cores taken from Antarctica and Greenland dated back only about 150,000 years and showed just two ice age cycles. The new core reveals four ice ages at roughly 100,000year intervals, shedding new light on how the icy interludes end.

‘Some really large changes’

All four appear to have given way to balmier times after levels of the heat-trapping gases carbon dioxide and methane rose by amounts smaller than the increase blamed on human industry in the past century.

The multinational team reported its findings in the June 3 1999 issue of the journal Nature.

Petit and colleagues found carbon dioxide levels rose from about 180 parts per million during each ice age’s height to 280-300 ppm in the subsequent warm periods ~ far below the current CO2 levels of 360 ppm.

Methane levels, meanwhile, rose from 320-350 parts per billion during the icy interludes to 650-770 ppb during the warm spells. Current methane levels are 1,700 ppb.

The levels of both greenhouse gases are expected to continue their rise in the next century due to continued burning of fossil fuels such as coal and other human activities.

“This study is probably the most convincing evidence to date that humans are making some really large changes to Earth’s climate system,” said Jonathan Overpeck, head of the paleoclimatology program at the National Geophysical Data Center in Boulder, Colorado.

Beyond natural variation: “What this says is we’re going well beyond the bounds of natural variation.” Petit estimates that the rising greenhouse gas concentrations contributed to about 50 percent of the post-ice age warming; he attributes the remaining heat to periodic shifts in Earth’s orbit that increase the amount of sunlight warming the planet. The natural rise in the gases was attributed to a variety of factors, including changes in oceanic processing of C02, increased plankton activity and the return of methane-producing swamps.

But the core also appears to call into question previous research suggesting a 500- to 1,000-year lag time between the post-ice age temperature increase and the CO2 increase.

Instead, the core suggests temperatures rose in step with rising C02 levels, a finding of interest to scientists studying global warming.

“This core is telling us to get busy and understand the climate system because it really could change,” said Richard Alley, a professor of geosciences at Pennsylvania State University

Ciao

2. As for your salary….I dont care! My only point is its just a joke 1st year out of uni as “not believable”

Do you have any depth other then

JBOT response

Iam not privvy to ice cores just know who assessed and where I read this. Get some depth and substance!

Minding explaining to me how the ice cores tell you what temperature it was??? I would love to know.

And may I add Mark “Tubby” Taylor endorsed as Fujitsu….so Iam doing my bit to test the theories! LOL

I have put up a lot of comments and views…..good to see Jbot with last whatever T** F*** IT means chim in. I felt like he bowled a wrongun when his was actually a mediocre slow full toss. Gee that was returned into the grandstands like Kevin Pietersen displays against the Aussies (NO NAME WOULD AGREE)!

LOL

the weather we are having today in terms of droughts and floods was acurately predicted over 100 years ago and it was mapped out with reference and study relating to the moons and earths cycles etc.
these patterns were acurately predicted with out any consideration of global warming.

does global warming now cause king tides too and not the moon?

who are you to say your version is right?

my version simply says that there has not been any warming over the 150yr old records i presented. that can not be manipulated or misinterpereted.

how many scientists have personally stuck a thermometer up the suns bum?

as i said with all these theories that have been presented only 17% believe it is ocurring
