This is Science Friday. I'm Ira Flato. It's Climate Week in New York City. The UN is holding the

Climate Ambition Summit. Experts are speaking on stages and in panels. Climate activists are

marching in the streets demanding action. So this week, we're dedicating the entire show to

stories about the climate crisis. Later in the hour, we'll have a conversation with climate

scientist Michael Mann about what we can learn from climate history and how history gives him hope

for the future. We'll also talk about the science of climate comedy. Yes, what makes a good joke

and why the climate movement could and should be funnier. But at first, as I mentioned,

Climate Week in New York City is coming to a close. There were hundreds of events, including

one from Science Friday this past Monday, encouraging conversation and action around our climate

crisis. The week-long event took place alongside the UN General Assembly meeting, and with it

came protests demanding world leaders and large companies take bigger action to end fossil fuel use.

We need to We need Queen of

The planet is all we have

The planet is all we have

It's our only hope

The only home that sustain

That we rely on

Please keep on fire

Never get tired

When you get tired, recharge.

To catch up on this week's climate news is my guest, Swapnikrishna, a journalist based in Philadelphia, Pennsylvania.
