TORONTO Although the global havoc wreaked by the coronavirus appeared to take precedence over all else in 2020, the issue of climate change didn’t just disappear, even if it did take a backseat. Despite a dip in greenhouse gas emissions due to the pandemic, the Earth is still on course to warm up by more than 3 C by the end of the century, according to the United Nations Environment Programme’s recent annual assessment of emissions levels. While that may not seem like a lot, consider that the planet has already experienced more frequent draughts, wildfires, and extreme storms since warming a little more than 1 C since pre-industrial times.
