Climate is changing quickly, and it's up to us to act

Hey there, time traveller!

In the same week that Doug Ford won the provincial election in Ontario, scientists announced that the Antarctic ice shelf is melting three times faster than they thought.

While it is true that Ford’s election victory has generated more heat than light, it is his opposition to Ontario’s carbon tax that will speed up such melting in the future. Yet a year ago, neither event would have been predicted by the experts.

In other words, whether we like it or not, things change.

On top of the recent heat wave in the Arctic (during which Churchill hit 30 C) — and record temperatures across Canada for this time of year — the news from Antarctica is particularly disturbing.

Global warming, leading to extreme weather around the planet, is disrupting predictions as well as the lives of millions of people. In situations where political rhetoric (instead of science) drives decision making about the environment, however, facts don’t seem to matter.

So we spend billions more than it is worth to buy an old, leaky pipeline, and billions more to build the Pipeline to Nowhere to ship bitumen that should be left safely in the Alberta oilsands. We sign agreements with Argentina to "study" whether fossil fuel subsidies are a good idea, when smart money has already divested and reinvested in alternatives.

If our scientific predictions are not keeping up with the accelerating effects of global warming, our political performances are 50 years behind reality — and slipping further.

We need to see these decisions for what they are: cynical investments in business as usual, betting against a sustainable future for everyone in order to make money for a few people today. You can make a lot of money predicting the decline of stocks; in fact, you could probably calculate it is easier (and faster) to make a pile on the stock market by shorting stocks rather than by waiting for them to gain in value.

In a volatile world market, in which a presidential tweet can send stocks crashing in an hour, there is money to be made in disaster.

In comparison, however, Mother Nature can change market trends just as quickly — and in a time of global warming, those changes could be catastrophic and irreversible.

Predictions about what happens when the Antarctic ice sheet breaks away or melts vary wildly. Some of the worst forecast a rise in sea level (with continued high greenhouse gas emissions) of up to 2.4 metres by 2100.

Think about it: 2.4 metres. For the metrically challenged, that is more than 71/2 feet.

If the models are not keeping up with the data, and if we continue to build and use pipelines, that end date will be a lot sooner than 2100.

Most people, especially younger ones, are not sure what they will be doing in 2050. At the rate things are going, billions of people around the world could be swimming by then.

I’ve been fortunate to be part of a small group of people that is providing a technical review of the global version of GEO 6, the latest Global Environmental Outlook prepared by the United Nations Environment Program, which is due to be released in March.

Watching colleagues around the world wrestling with the data — finding it, interpreting it, putting the pieces together — reminds me how difficult it is to know exactly where we are or where we will be even in 10 years.

But trends are clear. It is also clear that we do not have to do anything to ensure a high-carbon future, one where the dangerous effects of global warming change the conditions of life for many people on the planet.

Some will be floating; others will suffer from extreme heat (of more than 50 C) in which nothing can grow or live.

The politicians in office now, including the Doug Fords, are the ones who have the power to make decisions on our behalf to change that grimly inevitable future. Mother Nature does not attend campaign rallies, nor does she have a Twitter account.

What we say doesn’t matter; if we don’t change how we live together, the planet will simply do it for us — more rapidly, it seems, than even the scientists think.

Yet our political systems, even in a democracy, are failing us faster than the Antarctic ice is melting. Far more people in Ontario stayed in bed on election day than those who gave Doug Ford and the Progressive Conservatives their majority government.

Refusing to vote because you don’t like the choices is not a morally superior position. At such a critical point in the history of our civilization, it could be disastrous.
