Records of climate change and CO2 concentrations go back 420,000 years with certainty, and for about 20 million years with some degree of confidence.

For that 420,000 years, there is a direct correlation between CO 2 levels and temperature. The present level is higher than it has been in that time period.

There is no uncertainty any more. Global warming is here and it is certain to approach something that the Earth has not experienced in the whole of human history.

Yup and since 1940 the temperatures have actually been decreasing, not increasing.

The water vapour traps the CO2.

If you have read somewhere that temperatures have been decreasing since 1940, then you must have been wearing your glasses upside down.
