Description
We've known for decades the world is warming, so it shouldn't come as a shock when some records get broken along the way. But what has set off alarm bells among the scientists who study our changing climate recently is just how fast it's happening, in ways that don't match up with any previous models. From ocean temperature to sea ice, forest fires to heat domes and the world's daily average temperature record being broken at least twice just this week, warning lights are flashing.Is this truly the tipping point for our climate crisis? What does that even mean in this context? And as the bad news rolls in, is there another tipping point coming—a moment in which we collectively realize we can't survive without massive change?GUEST: Catherine Abreu, Executive Director of Destination Zero

Why the future of covid vaccines might not require a needle: By now many people assume we'll be getting annual covid boosters for the rest of our lives. That's possible, but there are other possibilities, too. In the past two years we've learned so much about how to rapidly create and deliver vaccines that there are projects in front of us that could offer much more optimistic futures. At McMaster University, one of them involves no needles at all... and might eliminate the need for yearly updates. GUEST: Dr. Matthew Miller, Associate Professor in the Department of Biochemistry and Biomedical Sciences at McMaster University by The Big Story
