Shellenberger: "I interviewed the lead author of the Nature Comment, Professor Timothy Lenton of the University of Exeter, I asked him about a verb tense I found curious. Lenton notes that the West Antarctic ice sheet “might have passed a tipping point” but goes on to say “when this sector collapses, it could destabilize the rest of the West Antarctic ice sheet like toppling dominoes — leading to about 3 metres of sea-level rise on a timescale of centuries to millennia.”
“When you say ‘when,’” I asked, “does that mean it’s an inevitability that it will collapse?”
“Well, we can’t rule out that it’s on the way out,” he said. “Any glaciologist specialist will tell you that we really want more data. Because it’s not trivial to monitor what’s going on in West Antarctica.”
“So the right word in your view is ‘when’ not ‘if’?” I asked. ...
Justin Ritchie, a researcher at the University of British Columbia, highlighted 11 conditional statements in the four paragraphs summarizing the complicated causality for a “global cascade” of tipping points.“ I might be the only one,” writes Ritchie, “but after reading it I’m actually less convinced about imminent climate tipping points. One example: if it takes 11 ‘if’ statements to support an opinion, then it’s time to revisit the opinion’s substance.” (The word “could” is used 26 times.)
CNN: A new United Nations report paints a bleak picture: The commitments countries pledged to limit the climate crisis are nowhere near enough to stave off record-high temperatures. Delaying change any further will make it impossible to reach desired temperature goals.The time for "rapid and transformational" change to limit global warming is now, the report says.The UN Environment Program (UNEP) 2019 Emissions Gap report calls on countries to strengthen the commitments made in the 2015 Paris Agreement to stall climate change.
'The oceans heated less rapidly … from 2005 to 2017, than … from 1993 to 2005.' ...It’s obvious that the ocean heating rate – characterized by the slope of the graph – slowed down over this period, especially from 2003 to about 2008 when ocean heating appears to have stopped altogether. Both the IPCC’s table and figure in the report completely contradict its conclusions.This contradiction is important not only because it reveals how the IPCC is a blatantly political more than a scientific organization/
Paul Homewood: "In short, no matter how you slice and dice the numbers, using heavily manipulated economic data as a measure of hurricane activity is a poor substitute for the actual climatic data, which tells a totally different story."
