U.N. climate change report points blame at humans. The world’s getting hotter, the seas are rising and the U.N. climate change report says humans are the likely cause.
The full text of the report is here.
I know at least one reader will push back on this study, but here are some additional details:
A total of 209 Lead Authors and 50 Review Editors from 39 countries and more than 600 Contributing Authors from 32 countries contributed to the preparation of Working Group
As far as anyone can tell, there is no scientific or statistical basis for their 95% confidence statement – in spite of their own rules, they have NEVER documented the basis for their “certainty.” It simply is another way of saying we have a [sort of] consensus that human activities are making the world warmer [even though it hasn’t warmed much at all over the last 15 years; nor has sea level rise accelerated; nor have storms intensified – or even become more frequent…].
It is a well-established psychological fact that we humans over-estimate certainty. Our evolutionary defense mechanisms work against us and make us poor natural statisticians. For example, this is why so many overestimated the “stability” of mortgage CDOs, which led to the Great Recession.
It also is true that the statements in the original draft were ratcheted significantly upward – made starker. We saw this in a few of the earlier AR reports, i.e., the politicians exercised – ahem! – “managerial license.”
In other words, the stark lead statements aren’t justified by the science – and I’m more than 95% certain of that!
