It has never been so simple.

"Warming of the climate system is unequivocal.
Human influence on the climate system is clear.
Limiting climate change will require substantial and sustained reductions of greenhouse gas emissions",

states the Intergovernmental Panel on Climate Change (IPCC) in their latest report. It is even more impressive to bring it down to these clear statements knowing that 259 authors and more than 800 expert reviewers have contributed to the fifth Assessment Report that covers 2000 pages. The Working Group also produced a very valuable Summary for Policymakers (SPM), only 22 pages long, that was word by word approved by 195 governments.

And what does this mean for us? Climate mitigation and adaptation to a changing climate remain the important key words. We need to substantially reduce greenhouse gas emissions, and at the same time be aware of how climate hazards will continue to affect our lives. Stronger storms, severe flooding, rising sea levels and prolonged heat waves – we can deal with them if we prepare. We can build stronger buildings, construct flood protection measures, ensure sound land-use planning and make sure we have space for trees and vegetation within cities.

"Unequivocal" sounds quite clear. "Clear" sounds ... clearcut as well. But I was quite struck by the "95%" confidence number that was widely reported on. My immediate reaction was that 95% seemed, well, not unequivocal. I was surprised that it wasn't possible to make a stronger statement.

I found the attached blog post very interesting on the matter of confidence in statements about climate change by the way
