DEBT FINANCING. Climate change could cost billions a year by 2020

Climate change could cost Canada billions a year as early as 2020, depending on how severe it is and how well the country adapts, says a report released Thursday morning.
The National Round Table on the Environment and the Economy looked at the cost of climate change on Canada's prosperity, public health and in coastal areas affected by weather events.
The government-funded think-tank estimates the cost of climate change for Canada could start at roughly $5 billion per year in 2020 and increase to between $21 billion and $43 billion per year by 2050. The average annual cost of climate change is expected to be roughly 0.8 per cent to 1.0 per cent of GDP by 2050, the report says.
It also found that climate change could result in additional deaths from heat and air pollution. Looking at Vancouver, Calgary, Toronto and Montreal, the report projects three to six deaths per 100,000 people per year in the 2020s, with impacts worsening in future decades.
Researchers projected the cost of climate change based on four scenarios ranging from rapid population and economic growth combined with high climate change to slow population and economic growth with low climate change.
It found there was a small chance the cost could go as high as $91 billion per year by 2050 given fast growth and a great deal of change in the climate, or sit at $21 billion a year given low climate change and slow growth.
The report says adaptation is key to limiting costs.
"Global mitigation leading to a low climate change future reduces costs to Canada in the long term. This reinforces the argument that Canada would benefit environmentally and economically from a post-2012 international climate arrangement that systematically reduced emissions from all emitters — including Canada — over time," the report says.
The report recommends the government invest in research into the economics of climate change effects and adaptation, model and cost out climate impacts, and work with universities and the private sector to get help with adapting to climate change.
