The list of destructive post-tropical storms and hurricanes which have tracked through Atlantic Canada over the past few decades is an increasingly lengthy list. From Juan in 2003, Igor in 2010, Dorian in 2019 and Fiona in 2022, plus the many other damaging storms that have moved through, this region is certainly in a period of high tropical-storm activity.
Why do oceans matter for climate change?
As the climate crisis gets worse, oceans — the planet’s greatest carbon sink — can no longer be overlooked. Spanning 70 per cent of the globe, oceans have absorbed nearly a third of the planet-warming greenhouse gas emissions caused by humans and 90 per cent of the excess heat those gases create. The heat stored in the Earth’s entire atmosphere is equal to what’s stored in the top few metres of our oceans. If that wasn’t enough, oceans produce more than 50 per cent of the planet’s oxygen and regulate our climate and weather patterns.
