Peak wildfire season is just beginning on the West Coast, but 2020 is already another unprecedented year. In California, more than 2.2 million acres have burned so far this year, beating an all-time record of 1.6 million set just two years ago. And in the Pacific Northwest, where Portland’s air quality hit the worst in the world on Monday, raging fires have produced never-before-seen poor air quality that threatens the health of millions. More than 500,000 people in California, Washington and Oregon are under evacuation orders, and dozens of people have died. Kerry Klein of Valley Public Radio in California’s San Joaquin Valley, and Oregon Public Broadcasting reporter Erin Ross talk about the toll of the fires in their regions, the role of climate change and other factors, and what the rest of the fire season may bring. Plus, with record heat and fires raging in the American west, and the Gulf Coast facing still more hurricane activity, is climate change becoming a more prominent issue for U.S. voters? Senator Edward J. Markey of Massachusetts thinks so. He recently repelled a primary challenge in what he calls “a referendum on the Green New Deal.” Now, just weeks before the November elections, candidates from both parties are forced to confront hazards worsened by climate change. Senator Markey joins Ira to discuss the Green New Deal, energy options, and environmental policy priorities for this election year—and many years to come. Subscribe to this podcast.
