Comfortably settled climate scientists (room service eases jet lag) jetted into New Zealand last week to discuss how modern life, which presumably includes air travel, is riling Gaia ever which way. It was there, at this gathering of great minds and grants, that Mr Climategate explained all.
Few stars in the frothy firmament of academic climate science shine more controversially than Dr Michael E. Mann, creator of the notorious “hockey stick” curve, gloomy prognosticator, conspiracy theorist, co-author of The Madhouse Effect: How climate change denial is threatening our planet, destroying our politics and driving us crazy, anti-Trump activist and fan of climate toothpaste, the only anti-apathy oral hygiene product with UH-OH formula.
The Distinguished Professor of Atmospheric Science and director of the Earth System Science Center at Penn State University, USA, was in New Zealand last week, where he gave a keynote lecture at the Second Pacific Climate Change Conference.
Radio NZ’s Kim Hill caught up with him for a 32-minute interview.
Hill: Can you attribute recent weather events to [dangerous anthropogenic] climate change? (1.40min.)
Mann: You can. In fact, there are droughts, wildfires and floods occurring without any precedent in the historical record where we can now show [the reality of anthropogenic climate change] using computer model simulations.
You can run two parallel simulations; one where carbon dioxide is left at pre-industrial levels, and a parallel simulation where you increase these levels in response to the burning of fossil fuels. You can look at how often a particular event happens in both counterfactual worlds.
What on Earth is a “counterfactual world”? Struggling to prove an anthropogenic influence in the “actual” world, members of the so-called climate detection and attribution (D&A) community were forced to create virtual “worlds” to run their computer games, an opaque process known as in silico experimentation.
