We’re entering the last week of the first month of 2021 and I already feel like I need a whiplash collar. As Canadians gaze south of the border, we’ve seen an attack on democracy, impeachment and inauguration take place at the same building on successive Wednesdays. Regardless of your political beliefs, it was hard not to be warmed by the sense of optimism that flowed from the ceremonies to inaugurate Joe Biden and Kamala Harris as the new president and vice-president. The highlight of the day came from 22-year-old poet Amanda Gorman, who spoke of the need to “lift our gazes not to what stands between us but what stands before us.” Her pledge to “raise this wounded world into a wondrous one” is the message of hope we have been seeking for a long time now.

In the spirit of all of us who yearn for a better world, I’ve assembled some recent stories from across the global network of The Conversation that offer some hope.

Have a great weekend and we’ll be back in your Inbox on Monday.
