Letter to the editor (Globe and Mail): A matter of degree

Publication Source:  The Globe and Mail
In an otherwise excellent column (Amid Dire Warnings, Canada is Missing in Action – Nov. 19), Jeffrey Simpson uses the word “target,” as many do, in reference to scientific warnings to avoid a two-degrees-Celsius global average temperature increase. Hitting this target condemns humanity to generations of destabilized climate conditions. It’s more of a tipping point. When the IEA speaks of “potentially catastrophic” climate change, it means shooting past this increase into runaway global warming.
