Global Warming

sas,
try looking at things with an open mind.........or are you scared yours might blow away again?

Try reading what I wrote you little man

Ooohhh ark at 'im!.
Do you have a small penis?

I never said it wasnt happening. Try reading what I wrote you little man

Classic spin tactics. Invent something that you never said, then attack it

I wondered when the Chief Village Idiot would turn up - and here he is right on cue.
Where's Sancho today?

ah here he is.

The fascinating thing is the parallel between the "ice age" in the 1970's argument, which principally was brought into question by sizzling hot summers, the same thing has happened, a bunch of cold winters have torpedoed Global Warming. More worrying is that the sunspot cycle is delayed, which happened in the middle ages, causing an ice age. One scientist wrote "I hope I'm wrong..."

From the little I have seen, there have always been warming and cooling periods in earth's history. Is that true?

If we didn't know that the earth tips over on its orbit round the sun, would we be having arguments about global warming then ice ages every year?

We pump billions of tonnes of CO2 into the atmosphere every year.

The atmosphere weighs about 5,000,000,000,000,000 tonnes. One American billion tonnes is 0.00002% of that mass.

The CO2 content of the atmosphere is 0.038% so one American billion tonnes of CO2 would increase the content by a factor of 1.000526 or by about 1/1900th.

That is, ignoring the CO2 absorbed by the sea and used by green plants. And ignoring the CO2 absorbed by the moisture in the air to become carbonic acid which falls as acid rain on Norwegian fir trees.

By jove, you've cracked it!
That must be it, you absolute genius, it's eluded thousands of scientists round the world.

Yes.
Of course it all started going pete tong when dinosaurs discovered land rovers, and Dobbie the village statto was given a hockey stick and some crayons for Xmas.

Yes indeed there has been 30 years of cooling followed by 30 years of warming since the temperature records began.

1880- 1910 Global cooling
1910-1940 Global warming (polar cap similar to recent minimum)
1940-1970 Global Cooling
1970-2000 Global Warming
2000-2030 Global Cooling

etc etc.

This is why Easterbrook predicts cooling and then warming in 60 years to reach the same temp we had in the Medieval warm period. A no brainer once you look into the temperature records.



At the moment his predictions are much closer than the IPCC.

If you want to calculate the effects of CO2 a back of the envelope calc. of Venus (96% CO2 atmosphere) and extrapolate between Earth's concentration and Venus's taking into account solar radiation closer to the sun, the result is warming of several milli-Kelvin.
