ANJALEE KHEMLANI: Good afternoon, and welcome to "A Time for Change." I'm Anjalee Khemlani here with Marquise Francis. Today's the first day of Black History Month, and we're going to kick it off speaking about the jump in Black medical student enrollment in a moment. But first, climate change.

It's top of mind right now as storms continue to rage around the planet and as the world prepares for the start of the Winter Olympics, which will take place for the first time entirely on man-made snow this year. Opening ceremonies are on Friday, and people are asking-- with global temperatures rising, will we hit the point when there just isn't enough winter for Winter Olympics?

MARQUISE FRANCIS: Right, and I put that question--

LINDSEY VONN: Well, I mean, we talk about it all the time-- it's in decision making for races, for just skiing in general. I mean, you can't deny that global warming exists, and that the world is changing, and that we have to make the change in a huge way. But I mean, skiing is not going to exist.

Winter sports are not going to exist if we continue down this path. And we see it firsthand. I grew up skiing on glaciers in Austria since I was nine, and they are-- literally, they don't exist anymore. And so for us, again, it's right in front of our faces. But to many, it's not quite as apparent.

So I'm not sure how we can make a change substantial enough to fix what's happening. But I know that sports can have a big role in it, because I think that we can shed light onto people that maybe don't believe in it or aren't convinced.

MARQUISE FRANCIS: And that was Alpine skier Lindsey Vonn who won three Olympic medals and is now an NBC Olympic correspondent. She was talking about the effects of climate change to the Winter Olympics. And our first guest today does not need any convincing that not only is climate change a real thing, but it's also catastrophic.

In fact, he's working to inform others that it's really now or never. Let's bring in Mustafa Santiago Ali, an environmental justice activist and policymaker-- someone whose perspective is necessary to the conversation, but especially this month. Mustafa, thank you so much for joining us today. I simply want to start-- are we at risk of losing winter?

MUSTAFA SANTIAGO ALI: Well, you know, every aspect of society is going to be impacted by climate change. And, of course, winter and our seasons are connected to these changes that we see happening all across our planet. So the answer is, yes.
