CO2, Temperatures, and Ice Ages

It is generally accepted that CO2 is lagging temperature in Antarctic graphs. To dig further into this subject therefore might seem a waste of time. But the reality is, that these graphs are still widely used as an argument for the global warming hypothesis. But can the CO2-hypothesis be supported in any way using the data of Antarctic ice cores?

At first glance, the CO2 lagging temperature would mean that it’s the temperature that controls CO2 and not vice versa.

But this is the climate debate, so massive rescue missions have been launched to save the CO2-hypothesis. So explanation for the unfortunate CO2 data is as follows:

First a solar or orbital change induces some minor warming/cooling and then CO2 raises/drops. After this, it’s the CO2 that drives the temperature up/down. Hansen has argued that: The big differences in temperature between ice ages and warm periods is not possible to explain without a CO2 driver.

Very unlike solar theory and all other theories, when it comes to CO2-theory one has to PROVE that it is wrong. So let’s do some digging. The 4-5 major temperature peaks seen on Fig 1. have common properties: First a big rapid temperature increase, and then an almost just as big, but a less rapid temperature fall. To avoid too much noise in data, I summed up all these major temperature peaks into one graph:

Fig 2. This graph of actual data from all major temperature peaks of the Antarctic vostokdata confirms the pattern we saw in fig 1, and now we have a very clear signal as random noise is reduced.
