Now that is the crowd at one of President Trump's political rallies before the coronavirus pandemic put an end to his favorite form of voter communication.

And that's not all that's change. Could Trump's handling of COVID-19 and its

impact on the economy turn crowds against him? We'll hear from a noted historian a bit later on.

But first, the coronavirus and climate change. The shutdown of world economies has cleared the air

in some of Earth's most polluted places.

In New Delhi, online humorists are uploading pictures of the Himalayas, the Eiffel Tower, and the Statue of Liberty,

claiming they can now see landmarks thousands of miles away.

COVID-19 has done more to reduce emissions than climate scientists could ever have

dreamed of. But that raises a challenging question. Is there a relationship between the

pandemic and climate change? We'll hear some answers, and there's more than just one,

from Catherine Hayho. She is an atmospheric scientist with so many awards for distinction

that would take a whole podcast to list them.

At Texas Tech University, she's in several different departments.

She's contributed to several national climate assessments.

To suggest her standing as an international authority,

the pandemic cut short her trip to

Ireland and Scotland, where she was scheduled for 18 talks and 40 other events in less than

two weeks. She also hosts her own podcast called Global Weirding. Professor Catherine Heyho,

thanks so much for finding time to be with us.

It is my pleasure.

Before we get to the climate and the pandemic, tell us about your family history and the last pandemic of 1918.

That's right. Well, the last pandemic had two waves, just like many people fear of this one will too.
