The rise of carbon dioxide, methane, and nitrous oxide, all potent greenhouse gasses is documented in the latest IPCC report on climate change. The last four decades have witnessed successively warmer ones both over land and ocean. Over land the mean increase is 1.59 Celsius. Over the oceans it is 0.88 Celsius. The weighing of human versus natural cause is 97.27% for the former rather than the latter. The scale of the change is unprecedented when compared to paleoclimate records. This is the first of three postings looking at the findings of the IPCC 6th Climate Assessment.
