Well Johhny C, I can also find graphs to "prove" whatever argument I wish to make. In fact for your one graph I'll raise you you Five.
This first graph is from the Hadley Centre of Britain’s Meteorological Office and one of the four bodies measuring world temperature.
As you see, since 1998—an unusually warm year thanks to the “El Nino” pool of warmer water in the Pacific—the world’s temperature dropped back to a steady plateau, followed by a few years of cooling.
The second graph confirms both the halt in warming, and then cooling. It’s from the University of Alabama in Huntsville, which monitors the troposphere—from the ground to 12km altitude.
Only one of the four bodies measuring world temperature, in fact, claims temperatures are still rising. That’s NASA, whose program is run by Dr James Hansen, Al Gore’s global warming adviser and a controversial catastrophist whose team’s reworking of data has been heavily criticised for exaggerating any heating.
This third graph seems to confirm a cooling. Despite media scare stories about a melting North Pole; sea ice has grown so fast in the southern hemisphere there is now more ice in the world than is usual, says the US National Oceanic and Atmospheric Administration.
Graph four shows us that global warming hasn't in fact given us more cyclones - or more tornadoes or hurricanes anywhere. Nor is their proof that cyclones are getting worse, according to the American Meteorological Society.
And, please, can we drop that old fiction that the world was never warmer? It’s a false claim made popular by a 2001 report of the IPCC, the United Nations’ climate group, which ran a graph, shaped like a hockey stick, claiming there was no warming for millennia until humans last century gassed up their world.
In fact, that “hockey stick” is now discredited, and last year Dr Craig Loehle, of the US National Council for Air and Stream Improvement, argued that using tree rings to work out past temperatures was clearly unreliable.
He instead produced a graph - Number 5 - of past temperatures using all other accepted proxies:
As this graph shows, and as I have already said, the world has gone though pervious periods where tempertaures rose. Where grapes were grown in the British Isles and farmers in Greenland grew crops on land now covered in snow.
Jonny C, you seem to place so much emphasis on what apparent scientists have had to say on the subject. So take into consideration the fact that 31,000 scientists, including world figures such as physicist Prof Freeman Dyson, atmospheric physicist Prof Richard Lindzen and climate scientist Prof Fred Singer, issued a joint letter in May 2008 warning governments not to jump on board the global warming bandwagon.
“There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the earth’s atmosphere and disruption of the earth’s climate.”
That’s why Ivar Glaever, who won a Nobel Prize for Physics, in June 2008 declared “I am a sceptic”, because “we don’t really know what the actual effect on the climate is”.
And it’s why the American Physical Society this month said “there is a considerable presence within the scientific community of people who do not agree with the (Intergovernmental Panel on Climate Change) conclusion that anthropogenic CO2 emissions are very probably likely to be primarily responsible for the global warming that has occurred since the Industrial Revolution.”
