CO2 Does Not Drive Glacial Cycles « Watts Up With That?

From "wattsupwiththat" comes this interesting analysis of the correlation between CO@ and temperature:

Consider the earth 14,000 years ago.  CO2 levels were around 200 ppm and temperatures, at 6C below present values, were rising fast.  Now consider 30,000 years ago.  CO2 levels were also around 200 ppm and temperatures were also about 6C below current levels, yet at that time the earth was cooling.  Exactly the same CO2 and temperature levels as 14,000 years ago, but the opposite direction of temperature change.  CO2 was not the driver.

  1. Very interesting observation.

  2. I've lived in Florida since 1990. Every 4 - 5 years we may have a cold spell that shows up as frost on the grass, but this year we have had the water in the bird feeder freeze at least 4 times. If we can find any pattern it would be that of getting colder not warmer.

  3. As politicians everywhere drive us into the brave world of carbon taxes and emissions trading, it is becoming more and more apparent that CO2 has nothing whatever to do with climate. How mush money will we waste before the politicians wake up to this massive con job?

  4. It's hard to generalise from our own experience in one location, but I agree Lois that there are enough reports of colder weather to make you think that is the trend.In fact despite the way the media reports the global mean temperature each year, it has been on a declining trend since 1998.We've had snow in places that have not had snow before in living memory (Baghdad a few years ago and the Emirates last winter), record cold spells in Europe and North America. There is a trend there and it isn't upwards.Australia is a special case as our climate is so variable and our records relatively brief that it's pretty hard to really know what is "normal".We do know however that we go through long dry spells and long wet spells.There are two intriguing paths of thought about our weather. One is that the movement of the moon is far more important than we know. There is a New Zealander called Ken Ring who does detailed long-term forecasts based on the moon and he is quite accurate in his predictions. Another school of thought is that the cycles of the sun are more important that we have known in the past. The late 1990's had great sunspot activity (indicating hotter than normal sun surface temperatures) and that coincided with "global warming." Since then there has been declining sun spot activity and in fact for the last few months virtually no sun spots at all and that has coincided with a cooling trend on earth.I think there is far more at work in our climate than the CO2 lobby would have us believe. I also think that the God who commanded it all to come into existence with a few words managed to factor in our dependence on coal and oil.

  5. The sun cycle is 11 years, I believe and there are very far reaching consequences to that. The northern lights are much more active during peak sun spot years and communications were interupted on quite a grand scale in Canada during the last peak. It would make sense that the moon would influence things too. And how can we not be warmer when the sun gets hotter?Yes I believe that God did factor in our needs.

  6. These things are obvious, when you think about them. The other obvious thing is that our planet is such a huge complex "organism" that it is crazy to reduce climate to just one minor gas in the atmosphere. People do like to make complex things simple and simple things complicated.

  7. I live in Brazil, I´m nature from here; the city of São Paulo, much polluted, but the levels of CO2, just seem to really show what man has done in the terrestrial biosphere, the ambition devoid of intelligence, has seriously affected all biodiversity, and the numbers mask the fact that more men are investing themselves against it.
