I'm not sure anyone believes that there is not some sort of a climate shift occurring on Earth.

nice little lesson there but has nothing to do with global warming.
climate scientists will agree with whomever funds their studies.
if climate scientist fully unserstand global warming, then why is there still debate on the subject?edit on 9/4/2012 by listerofsmeg because: (no reason given)

Yet again, reading comprehension is key. 150 years of [B]HARD[/B] data. Temperature records, meaning "on this date the temperature was 72°F", have only been kept for that miniscule amount of time. ANYTHING else is inferred. However, even 400,000 years of data is less than 1% of 1% of climate data, since the Earth is over 4 billion years old.
I even stated in my post that:

The Earth's climate is quantifiably shifting, But, again, any scientist that bases it on mankind's influence because of 1% of 1% of data should be strung up. Especially since they're ruining the global economy because of their egos.

(CNN) -- March 2012 will go down as the warmest March in the United States since record-keeping began in 1895, NOAA said Monday.
Kabul has been experiencing its worst cold snap and heaviest snowfall in 15 years, according to the national weather centre. It said the weather was expected to improve by the end of the week.
With temperatures reaching -40 to -60 degrees Fahrenheit throughout January, it was the coldest winter in local memory, and animals both froze and starved to death. Most families in Azraga said this year was even worse for them than the notorious dzud of 2010, in which almost 8 million head of livestock, or 17 percent of the entire country's animals, died and the government of Mongolia declared disaster status.
It was the first time in 26 years temperatures remained below average throughout the three winter months in eastern to central Japan and western to southwestern Japan, and the first time in northern and northeastern Japan in 11 years.
Temperatures were at normal levels in Okinawa and on islands in southern Kagoshima Prefecture.
Do you have quantitative evidence to suggest this?
A recent review paper, put together by both solar and climate scientists, details these studies: Solar Influences on Climate. Their bottom line: though the Sun may play some small role, "it is nevertheless much smaller than the estimated radiative forcing due to anthropogenic changes." That is, human activities are the primary factor in global climate change.
Human activities, responsible for a projected 35 billion metric tons (gigatons) of CO2 emissions in 2010 (Friedlingstein et al., 2010), release an amount of CO2 that dwarfs the annual CO2 emissions of all the world’s degassing subaerial and submarine volcanoes (Gerlach, 2011).
The greatest volcanic impact upon the earth's short term weather patterns is caused by sulfur dioxide gas. In the cold lower atmosphere, it is converted to sulfuric acid by the sun's rays reacting with stratospheric water vapor to form sulfuric acid aerosol layers. The aerosol remains in suspension long after solid ash particles have fallen to earth and forms a layer of sulfuric acid droplets between 15 to 25 kilometers up. Fine ash particles from an eruption column fall out too quickly to significantly cool the atmosphere over an extended period of time, no matter how large the eruption.
Sulfur aerosols last many years, and several historic eruptions show a good correlation of sulfur dioxide layers in the atmosphere with a decrease in average temperature decrease of subsequent years. The close correlation was first established after the 1963 eruption of Agung volcano in Indonesia when it was found that sulfur dioxide reached the stratosphere and stayed as a sulfuric acid aerosol.
Without replenishment, the sulfuric acid aerosol layer around the earth is gradually depleted, but it is renewed by each eruption rich in sulfur dioxide. This was confirmed by data collected after the eruptions of El Chichon, Mexico (1982) and Pinatubo, Philippines (1991), both of which were high-sulfur compound carriers like Agung, Indonesia.
For example, Mount Etna in Sicily emits 3,000 tons of sulphur dioxide on an average day, which is equivalent to the UK's total industrial emissions.
One fact stands out: the Tambora eruption produced "only" 40 cu. km of ash yet it influenced the world climate over several years. Toba blew at least 16 times more ash into the atmosphere as well as a vast amount of sulphuric acid, and that its debris reached much higher levels, staying in the atmosphere much longer. Particles blown into stratosphere could have remained there for centuries, even millennia, blocking and altering the influx of solar energy to the lower atmosphere.
emphasis mine
Numerous questions remain. For example, why has there been only a 1 degree F increase in global temperature, when climate models predict it should have been twice that amount, given current greenhouse gas emissions? What other factors are influencing global climate? Have the oceans - been responsible for moderating warming by absorbing excessive greenhouse gases? What is their capacity to absorb still further increases? Do current climate models tend to exaggerate the effects of increased greenhouse gas emissions?
Why do we need Argo?
We are increasingly concerned about global change and its regional impacts. Sea level is rising at an accelerating rate of 3 mm/year, Arctic sea ice cover is shrinking and high latitude areas are warming rapidly. Extreme weather events cause loss of life and enormous burdens on the insurance industry. Globally, 8 of the 10 warmest years since 1860, when instrumental records began, were in the past decade.

Early Warning Signs of Global Warming: Downpours, Heavy Snowfalls, and Flooding
An increase in global temperatures will lead to an intensification of the hydrological cycle. This is because an increase in surface air temperature causes an increase in evaporation and generally higher levels of water vapor in the atmosphere.

i answer that with this...if you have 100 people look up and say the sky is blue today, and you have 1 person say the sky is orange, then i guess you could say that there is still a debate going on that the sky is blue.
"During the Middle Miocene (the time period approximately 14 to 20 million years ago), carbon dioxide levels were sustained at about 400 parts per million, which is about where we are today," Tripati said. "Globally, temperatures were 5 to 10 degrees Fahrenheit warmer, a huge amount."
The term Middle Miocene disruption, alternatively the Middle Miocene extinction or Middle Miocene extinction peak, refers to a wave of extinctions of terrestrial and aquatic life forms that occurred around the middle of the Miocene Epoch, c. 14.8 to 14.5 million years ago, during the Langhian stage of the Miocene.
