Climate change - humans 90% likely cause
Global Cool at Number 10 | Home | Climate Change re-re-confirmed, now it’s up to you

From BBC

“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.

    “very likely” is defined as “greater than 90% likely”.
