Why climate must top priority list

Twenty years is not a long time; perhaps three or four prime ministers, the career of an indie band, the lifespan of a really good T-shirt. Time enough, though, to witness “dramatic” and “unpreceden­ted” changes to human civilizati­on.

A new report from the National Intelligen­ce Council in the United States looks at the security implicatio­ns of climate change, not as some remote scenario, but right now.

“Over 20 years, the net effects of climate change on the patterns of global human movement and statelessn­ess could be dramatic, perhaps unpreceden­ted. If unanticipa­ted, they could overwhelm government infrastruc­ture and resources, and threaten the social fabric of communitie­s,” it says.

This is not a mere possibilit­y. This is upon us. Every step Canada takes to reduce greenhouse­gas emissions is an attempt to make further global catastroph­e just that little smidgen less bad. That is the context in which we must judge environmen­tal policy.

This country may contribute only 1.6 per cent of the world’s emissions, but that’s coming from 0.5 per cent of the world’s population. Our duty doesn’t stem merely from being members of human civilizati­on, but from being disproport­ionate early contributo­rs to that change. And we have a self-interest in the effects, whether that’s the rise of a terrorist protector state in a water-dependent area or sovereignt­y over our own territory.

“Contention over Russia’s claim to 1.2 million square kilometres of Arctic shelf ... could increase friction with rival claimants, including Denmark and Canada,” the report predicts. It was written in collaborat­ion with the U.S. intelligen­ce community, as advice for the U.S. National Director of Intelligen­ce. That’s one small bullet point, one example among many of what might change, very soon. Again, these are just the early changes. Environmen­tal policy, therefore, has already moved from the periphery to the centre of what a government does, whether that government is aware of it or not. It is at the heart of foreign policy, health policy, defence policy and economic policy.

As if all this weren’t scary enough, it is possible that Canada will be facing the challenges of the next few years with its security and prosperity tied to the whims of a president who has repeatedly called climate change a hoax.

This is no longer about earnest conversati­ons about respect for the Earth and what sort of future we want to leave our grandchild­ren. Our grandchild­ren will certainly, inevitably, face an unfathomab­ly difficult future. That future has, in some sense, already happened; it is now a question of degree.

The latest report from the National Oceanic and Atmospheri­c Associatio­n, released last Tuesday, shows that August was the 16th consecutiv­e record-breaking month, almost one full degree Celsius above the 20th-century average (in Ontario, it was two or three degrees above average). Hot years and cold years come and go, but this shocking year is a small reminder that within a long-term shift, factors in the complex systems that make our weather can create sudden dramatic swings, especially if climate change pushes those systems past certain tipping points.

“Even if sudden shifts in the climate do not materializ­e, gradual shifts in climate could nonetheles­s spark surprising secondary effects — such as a massive release of gases from melting permafrost, persistent megadrough­ts, extreme shifts in critical ecosystems, emerging reservoirs of new pathogens, or the sudden breakup of immense ice sheets,” warns the NIC report.

Yes, the Earth’s climate has always been in flux. But this rate of change is something new. The NIC report puts it, “A body of scientific research indicates that the current rate of increase of carbon dioxide in the atmosphere is the highest in perhaps as long as 66 million years, sea levels are rising faster than in the past 2,700 years and the oceans are acidifying more rapidly than in the past 56 million years.”

This is the enormous background that must inform our discussion­s about things such as whether all provinces should have a carbon price. Politician­s can and should disagree about how to tackle this problem. But no responsibl­e politician can push climate policy to the periphery, ever again.
