Nothing’s certain but uncertainty

October 31, 2015

Here’s an entertaining column by Mark Steyn about climate change and some reactions to his new book “A Disgrace To The Profession,” which is about what other climate scientists think of Michael Mann’s “hockey stick” graph of temperatures.

The defamation suit against Steyn by Michael Mann, inventor of the global-warming “hockey stick”, is about to enter its fourth year at the DC Superior Court.

The Certainty of Uncertainty

Nine years ago self-proclaimed “climate hawk” David Roberts was contemplating Nuremberg trials for deniers:

When we’ve finally gotten serious about global warming, when the impacts are really hitting us and we’re in a full worldwide scramble to minimize the damage, we should have war crimes trials for these bastards — some sort of climate Nuremberg.

But in his latest piece, at Vox.com, he’s singing a rather different tune:

Basically, it’s difficult to predict anything, especially regarding sprawling systems like the global economy and atmosphere, because everything depends on everything else. There’s no fixed point of reference.

Now he tells us. […]

More about those uncertainties; here’s an interesting article from the Christian Science Monitor.

Antarctica is actually gaining ice, says NASA. Is global warming over?

A new NASA study found that Antarctica has been adding more ice than it’s been losing, challenging other research, including that of the UN’s Intergovernmental Panel on Climate Change, that concludes that Earth’s southern continent is losing land ice overall.

In a paper published in the Journal of Glaciology on Friday, researchers from NASA’s Goddard Space Flight Center, the University of Maryland in College Park, and the engineering firm Sigma Space Corporation offer a new analysis of satellite data that show a net gain of 112 billion tons of ice a year from 1992 to 2001 in the Antarctic ice sheet.

That gain slowed to 82 billion tons of ice per year between 2003 and 2008. […]
