Smoke from the U.S. West Coast travels east and overseas

Smoke from the wildfires made its way to the other side of the country and over the ocean. Using data from NOAA, Reuters animated the smoke clouds over time: With climate change expected to exacerbate fires in the future, by worsening droughts and warming surface ocean temperatures, wildfire research is becoming especially important. Over the last year, the world has seen record fires in Australia, Brazil, Argentina, Siberia and now...

Mapping tree loss in rain forests over time

Bloomberg mapped tree loss between 2000 and 2019 in Brazil: “What we have seen in Brazil is that rainforest protection is a highly political issue,” says Gerlein-Safdi of the University of Michigan. “With every change in government, laws can change very quickly, both for better or for worse.” In some areas, the damage has been done.

The maps that shift back and forth between past districting and how things are now show the picture clearly.

Where schools are ready to reopen

For NYT Opinion, Yaryna Serkez and Stuart A. Thompson estimated where we’re ready: Our analysis considers two main things: the rate of new infections in a county and the county’s testing capabilities. We used guidelines from the Harvard Global Health Institute, which proposed a variety of ways to open schools as long as the county has fewer than 25 cases of Covid-19 per 100,000 people. We also used the World...
