I’ve been watching reality TV this week (yes I really was) on CNSC TV (not SCTV, but not dissimilar in some ways), the web channel of the Canadian Nuclear Safety Commission (CNSC).... Read more »
Hold on folks… the times they are a-changin’

By Paul Beckwith
Frankenstorm Sandy is a scary beast. A hybridization between a tropical hurricane and a mid-latitude cyclone, her behavior is not natural at all. Moving northward off the east coast, Sandy is turning left toward land instead of right toward the sea. Sandy’s being blocked from moving north by a high pressure area of enormous magnitude, and being sucked west by a low pressure region of very exceptional (and highly unusual) strength. Thus the designation “Frankenstorm”.... Read more »
URGENT: House Speaker blocking emergency debate on the massive Arctic ice melt
Submitted by John Bennett on Thu, 2012-10-04 00:05Dear Friend,
I'm on the bus writing about what happened in Parliament last Friday. I still can’t get the day out of my mind... Megan Leslie, NDP MP and Deputy Leader, called for an emergency debate in Parliament on the massive and frightening rapid ice melt in the Arctic this past summer.
Megan eloquently pointed out that the Arctic icecap is responsible for moderating the global climate, and without it we’re in a sea of trouble.... Read more »

You are now entering the nonlinearity zone…

Push something and it moves a little. Push it a little more and it moves a little more. This is called a “linearity” response. But sometimes a little push can lead to something totally unexpected! This is called “nonlinearity” and, contrary to what one might think, nonlinearities are inherent in most systems - like our atmosphere, for example. In fact, abrupt and unexpected change happens at some point in most systems - we even have a saying for such unexpected outcomes: a tipping point.
Until recently, our atmosphere and oceans behaved like linear systems: incremental dumping of greenhouse gases into the atmosphere caused incremental changes, like rising temperatures and predictable rates of ice melt. But things are now changing unexpectedly fast – nonlinearity is kicking in! We only have to look at the rapidly vanishing arctic icecap for astonishing evidence.... Read more »
Orwell would be impressed...
Submitted by John Bennett on Sun, 2012-09-23 20:05The climate change issue reached new heights in Canadian public dialogue this week. It wasn’t because of the unprecedented melting of Arctic sea ice this summer, the phony-baloney announcement about Canada’s ‘progress’ toward meeting its greenhouse gas targets, or government’s caving on real regulations for coal plants. Nope, it wasn’t because of any of these worrisome situations.... Read more »
