Environment, Energy and Economies - A Canadian Primer: CANADA IN A CHANGING CLIMATE Ray Hamm

Canada in a Changing Climate: Advancing our Knowledge for Action is the national assessment of how and why Canada’s climate is changing, the impacts of these changes on our communities, environment, and economy, and how we are adapting. Released in 2019, this report is about how and why Canada’s climate has changed and what changes are projected for the future. Led by Environment and Climate Change Canada, it is the first report to be released as part of Canada in a Changing Climate: Advancing our Knowledge for Action.


Canada in a Changing Climate: Advancing our Knowledge for Action  is a reader friendly government report. The bold print below is taken from a chapter on headline statements. The full report is available at https://changingclimate.ca/CCCR2019/ 


Canada’s climate has warmed and will warm further in the future, driven by human influence. 

Both past and future warming in Canada is, on average, about double the magnitude of global warming. 

Oceans surrounding Canada have warmed, become more acidic, and less oxygenated, consistent with observed global ocean changes over the past century. 

The effects of widespread warming are evident in many parts of Canada and are projected to intensify in the future. 

Precipitation is projected to increase for most of Canada, on average, although summer rainfall may decrease in some areas. 

The seasonal availability of freshwater is changing, with an increased risk of water supply shortages in summer. 

A warmer climate will intensify some weather extremes in the future. 

Canadian areas of the Arctic and Atlantic Oceans have experienced longer and more widespread sea-ice-free conditions. 

Coastal flooding is expected to increase in many areas of Canada due to local sea level rise. 

The rate and magnitude of climate change under high versus low emission scenarios project two very different futures for Canada.

Altona CAN! Apply the Golden Rule During a Pandemic

  The other day, someone who falls into the high-risk category for COVID 19 was picking up some items at the  Farmer’s Market.   Because of her own risk factors, but also because she has family members who are high-risk, she  wore a mask as is currently advised by public health.  She was confronted by someone who argued that COVID-19  was “blown out of proportion” and that “a true person of faith wouldn’t live in fear and wear a mask.”    I am disturbed by this behaviour on two accounts.  First, the person who confronted the mask wearing individual  is someone who works with vulnerable people,  and comments about her beliefs about COVID-19 being blown out  of proportion suggest to me that she likely wouldn’t be someone who would take the necessary precautions (at least  not outside of her working environment).  Case in point: her comments were not stated from a respectful distance  of 2 meters.  Rather,...

Plastic Picnics

  By Jack Heppner Finally, after living with Covid restrictions for so long, we have arrived at the summer picnic season! We  all look forward to times of “dining out” with family and friends, especially since that option is only  available here in Southern Manitoba for a few months every year.  My concern is that such events have too often become “plastic picnics.” I have an image clearly etched on  my mind that leaves me with a feeling that something has gone wrong with our picnics.  Two or three families have just finished a picnic in the park – perhaps a family gathering or simply  friends getting together. The feast is over and now the picnic tables are piled high with garbage, mostly  some form of plastic, styrofoam or paper. Cups, plates, cutlery, food containers, bags, wrappers, pop and  water bottles and everything else you need for a modern picnic!  But this is only the beginning of the unfolding tragedy. Now you see a couple o...
