“The climate models showed that greenhouse gas emissions had contributed to an increase in such summers, from one in 1,000 years to at least one in 500 years and possibly one in 250 years.” — Heidi Cullen Copy Share Image
“The last 10,000 to 20,000 years have witnessed a period of dramatic growth in human civilization. Indeed, our growth during this time is unique among all species, but it has been highly dependent on the overall consistency of the climate.” — Heidi Cullen Copy Share Image
