Hundreds of people attended a memorial service Sunday to mark the loss of Pizol glacier in the eastern Swiss Alps to global warming, NPR reports.

Why it matters: ETH Zurich university glacier specialist Matthias Huss told CNN that Pizol had "disappeared" after losing 80-90% of its volume since 2006. An April study by European researchers warns that from 2017 to 2050, about 50% of glacier volume in the Alps will vanish, "largely independently of how much we cut our greenhouse gas emissions."

The memorial took place as world leaders gathered in New York City for the UN climate summit this week.
An organizer of the "funeral march" tells CNN what's happening at Pizol is a "warning sign" about "what is going to happen if we don't change something about our behavior."
The April study determined that more than 90% of Alpine glaciers will disappear by 2100 if greenhouse gas emissions are left unchecked.

After 2050, "the future evolution of glaciers will strongly depend on how the climate will evolve," the study says.

Supreme Court clears way for first federal execution since 2003

The Supreme Court ruled early Tuesday that federal executions can resume, reversing a lower court decision and paving the way for the first lethal injection since 2003 to take place at a federal prison in Indiana, AP reports.

The big picture: A lower court had delayed the execution, saying inmates had provided evidence the government's plan to carry out executions using lethal injections "poses an unconstitutionally significant risk of serious pain."

More Republicans say they're wearing masks

Data: Axios/Ipsos poll; Chart: Andrew Witherspoon/Axios

Nearly two-thirds of Americans — and a noticeably increasing number of Republicans — say they’re wearing a face mask whenever they leave the house, according to the latest installment of the Axios-Ipsos Coronavirus Index.

Why it matters: A weakening partisan divide over masks, and a broad-based increase in the number of people wearing them, would be a welcome development as most of the country tries to beat back a rapidly growing outbreak.

Buildings are getting tested for coronavirus, too

Testing buildings — not just people — could be an important way to stop the spread of the coronavirus.

Why it matters: People won't feel safe returning to schools, offices, bars and restaurants unless they can be assured they won't be infected by coronavirus particles lingering in the air — or being pumped through the buildings' air ducts. One day, even office furniture lined with plants could be used to clean air in cubicles.
