“Climatic changes seen around the world are “very likely” to have a human cause, the Intergovernmental Panel on Climate Change (IPCC) will conclude. By “very likely”, the IPCC means greater than 90% probability. This is a stronger position than the global organisation took in its last major report in 2001.”
While “90% likely” is not a very good statistic, it does continue to underline the overall assessment that we must act.
