I blog about environmental and social justice issues because I am very concerned about the health of the interdependent web of life of which we are a part.

Vancouver, BC Under Water

Ok - not quite. 

Bing Thom Architects has investigated how global warming might transform Vancouver’s shoreline if no dikes are built. ...Keenan, who chairs the Vancouver planning commission, pointed out that sea levels are based on average tide, but climate change will be accompanied by increased storm surges. “You have to add on high tide and the impact of a storm to look at the development area that will be impacted,” she said....So what is the likelihood of dramatically higher sea levels? According to Hadi Dowlatabadi, a professor at UBC’s Institute for Resources, Environment, and Sustainability, a key consideration is what happens to the glaciers in Greenland and Antarctica. In a phone interview with the Straight, Dowlatabadi explained that as the oceans absorb more heat, they will expand. “Our current thoughts are that the amount of heat that is being absorbed by the oceans has already committed us to a sea-level rise of 40 or 50 centimetres this century,” he said.....Meanwhile, the U.S. Geological Survey reported last month that ice shelves are retreating from the southern section of Antarctica because of climate change. This area contains five major ice shelves, including the Wilkins Shelf, which has lost more than 4,000 square kilometres since 1998. The Larsen B ice shelf, which was in the same area, collapsed in 2002.
If we cared about our grandchildren,  we would all be working to reverse climate change. And working to mitigate its effects and  figure out how to adapt.  And working to create a truly sustainable way of life.....
