Scientists say weather getting harder to predict, warn British Columbians to be prepared

Scientists say climate change is making it harder to predict the weather and it is crucial that people are prepared for all possible scenarios.

Factoring in past weather patterns is becoming harder to doas weather becomes more volatile, experts say

Summer is just around the corner, and while B.C. is expected to have acooler and wetter one than last year, scientistssay climate change is making it harder to predict the weather and it's critical that people are prepared for all possible scenarios.

In 2021,wildfires sprang upmuch earlier than usual,with drought conditionsand a series ofdeadly heat wavesleading to widespread fire activity. Before Canada Day, temperatures rose above40 C in many parts of the province.

Experts say while this does not look like the case this year, climate change is making it harder to be precise about predictions.

The challenge, they say, is that to forecast future weather, meteorologists factor in past weather patterns something that is becoming harder to doas the weather becomes more volatile.

"Summers used to be hot. Winters used to be cold. Things were foreseeable," saysDave Phillips, senior climatologist with Environment and Climate Change Canada, speaking to The Early Edition.

Climatologists study weather patterns over time and Phillips says monitoring ocean currents that hugely influence weather patterns is a helpful tool, but he "wouldn't bet thefamily farm" on what's in store for British Columbians this summer and "only offer a guess."

And his guess is that it will be cool and wet, with August looking warmer than July and June looking like, well, "June-uary."

When there is a nice day, says Philips, you better pounce.

"You've got to take advantage of it because you never know what's around the corner," he said.

Paul Beckwith, climate systems specialist and professor at the University of Ottawa, says it isgetting more difficult to make weather predictions as the melting polar ice cap increases the "frequency, severity and duration" of extreme weather events.

"The statistics of weather has changed because the climate has changed," said Beckwith, speaking to On The Island.

Beckwith calls this new reality a"climate casino" because it's gettingharder to know what's coming and a lot of it is unlucky.

Be your own weather person

Because weather variability is increasing, both Philips and Beckwithwant British Columbians to be prepared for whatever the atmosphere has in store be it fires, floods, or, thinking longer term, the inevitable rising of sea levels in coastal communities.

Beckwith recommends people have a generator on hand in case a weather event cuts their power off for long periods of time.

And Philips wants people to pay attention to the weather around them rather than solely relying on the weather channel.

"People expect to be told by Big Brother that the storm is coming [their] way and I think that what we need to do is to be more of own weather person," said Philips.

"Don't leave home without getting the weather word, but also keep an eye on the sky."
