IPCC model predictions were badly wrong

Shows that ‘global warming’ is over.

CO2 did not cause ‘global warming.’

Facts: No correlation between C02 and global warming in the past.

1. Half of the warming in the past century occurred before CO2 began to rise sharply.

2. For 30 years after CO2 began to soar, global cooling occurred, rather than warming.

3. Of the 25 past periods of global warming, only the last one (the past 30 years) corresponds to rising CO2

96% of global warming periods in the past 500 years have no correlation with CO2

Computer models have predicted sharply rising global temp, but global cooling since 1998 has invalidated the models used for forecasting global climate change.
