Both temperature and CO2 much higher than present for 80 percent of last 600 million years

From Scotese  Professor of Geology University of Texas.     This negates the claims of the IPCC about levels being the highest since records began.   The"records"they refer to  are only the instrument readings which only began 1850.  The above graphic is the result of the use of proxies such as ice cores.  The alarmists statements are to scare the population.  Their statements are a deliberate deception and down right lies.
