Quirks & Quarks Host answers Viewer Climate Change Questions

The United States has its climate change personality – Bill Nye, “the Science Guy”.  CBC has Nye’s equivalent in Bob Mcdonald, a science journalist who for years has been the host of  the radio program “Quirks and Quarks”. From time to time McDonald has been interviewed on The National, the CBC news flagship.  Last night … Read more

White Christmas?  Bah, humbug!

So what if parts of Ontario have had the warmest Christmas Day since 1964.  And that record high temperatures were recorded throughout the Eastern US States. The basic climate conditions, i.e. El Nino, and the polar vortex, were favourable to warmer temperatures. Climate Scientists treat this short term phenomenon cautiously, and don’t necessarily attribute it to … Read more

Don’t be fooled by the weather! 

In several of our blogs we have noted that weather masks climate change. After last winter, the inhabitants of North Eastern North America (particularly residents in the Provinces of New Brunswick, PEI, Nova Scotia and Newfoundland & Labrador) will be sceptical of claims about global warming.   The last three months  will remind them of … Read more

Global Warming doesn’t mean “no more winter”!

The Polar Vortex (aka the Arctic Oscillation) has been the subject of comments in 4RG. Follow these links to see how 4RG has tracked changes in this generator of the cold weather North American has been experiencing this year.

Go to last year’s commentary on the winter of 2013 – the blog was based on articles from the US National Oceanic and Atmospheric Administration and the British Met Office.  Here is what we wrote:

 “. . . the Arctic Polar Jet Stream has gone “loopy”.  Usually the jet stream is a fast flowing high atmospheric air current found between air masses of significantly different temperature.  With the warming of the Arctic the temperature difference is less so the jet stream is weakening.   As it weakens, it starts to meander, looping to the South. The most recent atmospheric charts of the jet stream show significant loops.” [“Loopy”=1. full of loops. 2.Slang. a. eccentric; crazy; dotty . . . ]

Speaking of “ crazy” is there anything crazier than the Southern California experience of no rain for months ending with extreme rainfall from thunderstorms that brought mudslides, impassable roads, sinkholes, flash floods, power outages . . . you name it.  But according to TIME Magazine no relief from the drought conditions!

What the heck is a Polar Vortex anyway?

We here in Peterborough were caught in a cold snap for much of January and February, the coldest stretch in decades. Everywhere I went people were complaining about the winter and asking what happened to Global Warming. The weather reports were all talking about the Polar Vortex. What the heck is a Polar Vortex anyway?

Can we reconcile the apparent discrepancy between the coldest January in decades and global warming? I think so, and there is even pretty good evidence that the cold snap was caused by global warming.
