Canada's high school students may not be getting enough information on the negative impacts of climate change, scientific consensus behind human-caused warming or climate solutions, according to new research from the University of British Columbia and Lund University. Story here.

New research shows that condensation trails from aircraft exhaust are playing a significant role in global warming. Experts are concerned that efforts to change aviation engine design to reduce CO2 emissions could actually create more contrails and raise daily temperatures even more. Story here.

A popular farm fungicide, now banned in Europe as a suspected carcinogen, remains in widespread use in Canada today.

The European Union halted sales of all crop fungicides containing the active ingredient, chlorothalonil this spring. The move followed advice from its Food Safety Agency (EFSA) that chlorothalonil "may cause cancer in humans." Canada, on the other hand, re-approved the same product just over a year ago. Hard numbers on amounts still being applied in this country are hard to come by. But official government documents show it continues to be approved for use in no less than 29 crop protection products.  by Larry Powell A ground sprayer in Manitoba. Stats Canada says farmers in that  province apply fungicides "more frequently" than their counterparts  in any other province, "possibly due to its large potato sector." A PinP photo.

Chlorothalonil is the active ingredient in several agricultural fungicides used to treat mildew, blight and mold in many food crops.                                                    It's been used worldwide, since bing approved in the US in the '60s. Almost 5 1/2 thousand tonnes were applied to American crops in 2017, making it the third most-used fungicide there, only after copper and sulphur.  And, according to The Guardian, it's the most widely-used pesticide in all of the UK.

Chlorothalonil use in the US in 2011. A research project at the University of British Columbia, CAREX reports that 581 tonnes of chlorothalonil were sold in BC alone in 2010 - 1,121 tonnes in Ontario in 2008. No more recent figures are given and no other provinces are mentioned. But tables which remains posted on a Government of Canada website (see bottom), shows chlorothalonil remains approved for use in no less than 29 different agricultural products. And CAREX has reached the same conclusion as the EU. Its website declares, "Chlorothalonil is associated with cancer of  the kidney and stomach."  While Statistics Canada does not give a breakdown of active ingredients, the federal agency says almost one in four (23%) of all crop farms in this country applied fungicides of one kind or another in 2011. And it adds, farmers in Manitoba used them "more frequently than those in any other province," possibly due to that province's high level of potato production. Here's what the European study finds:  ·      Chlorothalonil binds to red blood cells, delaying its removal from the body,  ·      is very toxic if inhaled and can cause serious damage to the eyes and skin,  ·      mainly attacks the kidneys and forstomach, producing both benign and malignant tumours,  ·      slows sexual maturity in treated lab animals and causes them to give birth to underweight young, ·     produces acute risks to amphibians and long-lasting damage to fish,                  . could pose a hazard to groundwater, especially when it exceeds allowable standards.      But there was too little information to determine whether it harms wild mammals, aquatic species other than fish, or bees. (Earlier research, however, has linked it to diminishing numbers of bumblebees, as well.)The study was peer-reviewed by experts in the field. Canada' approach - a study in contrasts

In May of last year, Canada's Pesticide Management Regulatory Agency, PMRA - a division of Health Canada, released results  of its "re-evaluation" of chlorothalonil. The agency did impose some restrictions, including its use on cut flowers grown in greenhouses. (Even that restriction, however, does not need to be met until next spring.) But the PMRA's main finding was: "Most uses...meet current  standards for protection of human health or the environment. It’s continued registration is acceptable."

  Dear PMRA,

  
  

  I'm a journalist in Manitoba. I am attaching the draft

  
  
  

  of an article I am writing for my blog and perhaps

  
  
  

  some weekly newspapers here in Manitoba.

  
  

  My questions are;

  
  
  
  
  
  

  Will you be reviewing the status of the fungicide chlorothalonil, now that the European Union is banning it?

  • How do you explain the differences between the findings of the EFSA and your own re-evaluation?
  • Would you kindly review my attached script and correct any factual errors you may encounter?
  • Please feel free to include any additional comments you feel may be relevant, which I can include in my final draft. 

  Many thanks for your attention.

  
  

  Sincerely.

  Have a green day!

  Larry Powell

Photographer's Note

This is an aerial view of the Northern Alberta landscape, somewhere between Athabasca and Swan Hills. It consists of numerous shallow lakes, muskeg, and the typical vegetation including spruce, willow and poplars. The typical patterns of the vegetation are determined by the consistence and composition of the semi-solid soil underneath. 
The parallel lines that scar the landscape are seismic lines used for oil and gas exploration, and they cover good part of the province. Seismic exploration is somewhat similar in principle to radar, and even more similar to the ultrasound used in medical facilities. Straight, parallel stripes up to 10 m wide are cleared with bulldozers, and drilling equipment follows these stripes sinking explosive charges in the soil. The sound of the explosions bounces back of rock layers, is collected by listening devices and used for mapping the geology and potential resources. The statistic says that in this oil rich province more ground is cleared for seismic lines than by forestry.
