hmmmI shall remember that and I guarantee that it will come back to haunt you!
I agree. But equally, since we don't know what they were, we cannot just assume that the same processes are at play today either.Digit wrote:(The time lag is debated, but this is nonetheless irrelevant. No-one has ever claimed that interglacials are caused by rising levels of CO2. )
So what did? Till you can explain that how on Earth can you ignore the possibility that the sequence is repeating?
8 winters spaced 12 months apart would at least suggest that a 9th one will follow or logic at least vanishes!
Why should they be known? They're scientists, not rock starsDigit wrote:(are not known outside of climatological circles. )

They're not exactly in hiding ....... but there are thousands of them all around the world.Digit wrote: why in this heated debate are the climatologists then the only ones not getting their 15 mins of fame on TV?
Surely this debate would be better served if they did come out of hiding?
how many aids experts can you name DigitEqually Essan a few years ago we had more 'experts' on AIDs than sufferers, show people grant money and they will take it.

If by longevity you mean chemical stability, true, but water vapor has more affect on global temperatures than Co2 according to many atmospheric models. This is what I mean by significance.It's always been regarded as the most significant, in part due to it's longevity compared to others like methane. However, it's true the water vapour is the most common greenhouse gas.
According to Shimel et al the following volumes of atmosphere Co2 are released:Human contributions equate to about 25% of the total current level of CO2.
This is true, but they are now claiming the opposite. Why? The lag was based on actual samples of air trapped in the ice core, which means, thanks to Co2 longevity, they were able to directly measure it.The time lag is debated, but this is nonetheless irrelevant. No-one has ever claimed that interglacials are caused by rising levels of CO2.
When I have more time I may be able to post a link that shows a different result. As I recall the correlation held, but this was a time when it was significantly hotter than now, iirc. The total amount of Co2 is fairly constant on a whole (including stored gas). This may show there are limits on how much gas is released due to natural effects.How does this match with the Holocene Climatric Optimum and the MWP - when (supposedly in the latter case) the Earth was warmer than today and yet CO2 levels remained pretty constant.
Yes and the model which predicts this is in error. The present exponential Co2 rise has resulted in about 1/2c temp. rise.It's near certain that increases in atmospheric CO2 are down to human activity and the science says that for a doubling of CO2 we should see a 1c temp rise.
I agree with you 100%.The question is whether natural factors are also changing the climate, and if so, what the respective contributions of human activity and nature are, what feedbacks will occur and what may happen in future.
The other issue is the media hysteria and political cynicism - the latter resulting in taxes being introduced when it's plain they will have no impact on climate change etc
Meanwhile, there are numerous other ways in which humans are affecting climate change ...... These are the Inconvenient Truths which both sides prefer to ignore. (Apparently, blaming Brazil, Indonesia and Uganda for climate change is not deemed politically acceptable, even when it's the truth)
