Maybe This is Why the Canadian Government Does Nothing

That’s because global warming has the potential to be a boon for profit seekers. The reason: a hotter climate could undermine crops, leading to smaller harvests and higher prices.  By studying temperature and yield records from 1980 to 2008, the team of academics from Columbia University and Stanford University estimated that the global trend to warmer temperatures has led wheat yields to be 5.5 per cent lower than they would have been had the climate been stable, and corn yields to be 3.8 per cent lower.

The reduction spread out over the world was the equivalent to losing the annual corn harvest from Mexico and the wheat harvest of France.  There was upside for Canadian farmers from the research. In their number crunching, the researchers noted no effect on yields in Canada and the U.S., because temperatures haven’t risen in those countries as they have elsewhere around the globe. “Pretty much every climate model says that [North American farmers] will get warming too,” but it has not yet been affected by the trend, Dr. Schlenker said.

Some boon - higher food prices - more hunger.  And, as a commenter on the Globe and Mail site said  "The economic consequences of the instability created when other nations face declining crop yields and difficulty feeding all of their citizens is more likely than not to offset any benefits. One only has to look back to the the economic meltdown two years ago to see how bad things "over there" can cause havoc here."

Food Budget Ever Expanding?

Spending more money at the grocery store?  Notice that your food budget is consuming more of your income?  It's not your imagination....

Prices for food purchased from stores rose 3.7% in March [2011] , the largest year-over-year advance since August 2009. This increase follows a 2.0% gain in February [2011].   http://www.statcan.gc.ca/subjects-sujets/cpi-ipc/cpi-ipc-eng.htm

You can blame climate change food price increases.

 new research joins a small number of studies in which the fingerprint of climate change has been separated from natural variations in weather and other factors, demonstrating that the effects of warming have already been felt in the world..... scientists found that global wheat production was 33m tonnes (5.5%) lower than it would have been without warming and maize production was 23m tonnes (3.8%) lower. Specific countries fared worse than the average, with Russia losing 15% of its potential wheat crop, and Brazil, Mexico and Italy suffering above average losses. ...The losses drove up food prices by as much as 18.9%. http://www.guardian.co.uk/environment/2011/may/05/food-prices-global-warming?intcmp=122

I predict food prices will continue to increase.  We don't seem to be worried about climate change - at least not enough to take  steps to reduce greenhouse gas emissions .  So cliamte change will bite harder and harder - and food wil increase in price drastically.  Chew on that thought while you complain about your budget.
