Summary

In recent months, telecommunications companies in the United States have purchased a new part of the spectrum for use in 5G cellphone networks. Weather forecasters are concerned that these powerful signals could swamp out weaker signals from water vapor—which are in a nearby band and important for weather prediction. Freelance science writer Gabriel Popkin joins host Sarah Crespi to talk about the possible impact of cellphone signals on weather forecasting and some suggested regulations. In other weather news this week, Sarah talks with Pengfei Yu, a professor at Jinan University in Guangzhou, China, about his group’s work using a huge smoke plume from the 2017 wildfires in western Canada as a model for smoke from nuclear bombs. They found the wildfire smoke lofted itself 23 kilometers into the stratosphere, spread across the Northern Hemisphere, and took 8 months to dissipate, which line up with models of nuclear winter and suggests these fires can help predict the results of a nuclear war.

Welcome to the science podcast for August 9th, 2019. I'm Sarah Crespi. In this week's show,

0:52.1

we start with science writer Gabriel Popkin. He's going to talk

0:55.2

with me about a battle over bandwidth. This is between 5G, the new generation of cell phone technology

1:01.5

and weather forecasters that are concerned that this signal might interfere with our ability to

1:07.0

predict the weather. And I talk with Ponfeu about what an immense smoke bloom from 2017 wildfires

1:14.5

in Western Canada can tell us about the aftermath of a nuclear bomb.

1:23.5

Now we have Gabriel Popkin. He's a freelance science writer based here in Maryland. This week, he wrote about a battle over bandwidth between telecommunication and weather forecasting agencies. Hi, Gabe.

1:35.5

Hi.

1:36.1

The area of the spectrum at issue here is what the telecoms call 5G. Is accessing this new ban about making faster phones? Well, that's one of the potential

1:47.8

applications. And I should clarify, 5G actually already exists. Yeah. The major telecom companies

1:54.3

are starting to roll it out. There are a bunch of different frequencies that they're using and other

1:59.8

frequencies that they want to use

2:01.5

in the future. And this battle is over this one little piece of the frequency spectrum that

2:06.7

happens to be near a frequency that's very important for weather forecasters.
