Consider This from NPR - Why Wildfire Is Not Just A Western Problem
All over the east coast and Midwest, forests are getting hotter and drier. Many are also overgrown and overdue for wildfire. And increasingly, Americans are moving to areas where these forests and their homes tangle close together.
The fastest such growth is in the Southeast, where few consider wildfire much of a threat. Molly Samuel with member station WABE reports from Tate City, Georgia.
Additional reporting in this episode from Annie Ropeik of New Hampshire Public Radio and from NPR's Nathan Rott, who reported on fire risk in Wisconsin, home to the deadliest fire in American history.
In participating regions, you'll also hear a local news segment that will help you make sense of what's going on in your community.

Science In Action - Human induced climate change heats up fast
Scientists say the record-breaking Pacific North-West heatwave of recent weeks must have been caused by human induced climate change, but as Geert Jan van Oldenborgh explains to Roland Pease, despite a herculean effort to analyse the event in just a week, the precise mechanism to cause such an extreme and sudden event is so far bewildering climate modellers, exceeding even worst expectations.
Looking to the skies, Rosita Kokotanekova of the European Southern Observatory and colleagues have been getting excited about the discovery of a comet maybe twice as large as any observed before. Being so big, it has been spotted much further out from the sun and – if the best telescopes can be convinced to join the fun – will provide astronomers a chance to observe the core of the comet before the solar heat induces a gaseous coma to form as it nears the point in its orbit closest to the sun. It will be around for the next decade before continuing its several million year journey around our mutual star.
But it won’t get terribly close to earth, at least not as close as lumps of an asteroid that fell onto a driveway in the UK earlier this year. Dr Ashley King of the UK’s Natural History Museum is leading a consortium of scientists (benefitting from a rapid research grant by the UK’s STFC) who have now officially classified it and named it. The Winchcombe meteorite is a CM carbonaceous chondrite, meaning it represents the unspoilt early building blocks of the solar system. Falling like 4.5 billion year old leftover celestial lego, only a few are known around the world but perhaps none have been in scientists hands in such a short period of time, continuing its pristine survival.
Dr Pablo Tsukayama has published a preprint paper announcing a new variant of interest in the ongoing evolution of the SARS-CoV2 virus. Now named by the WHO as the Lambda variant, it seems it has driven the pandemic for much of this year in Peru – as much as 80% of cases – and large fractions of the outbreak elsewhere in South America. But as Pablo suggests, the reason we don’t know as much about it as for example the Alpha or Delta variants is likely because it hasn’t thus far affected the countries best equipped to do the analysis. Maybe that could change.

Village SquareCast - A Conversation with President Thomas Jefferson
In a live audience taping of The Thomas Jefferson Hour, we looked through the eyes of the author of the Declaration of Independence and marked our progress toward a more perfect union. We considered what both Mr. Jefferson and those of us charged with perfecting America today might think is yet to achieve.
Thomas Jefferson is portrayed by Presidential Scholar Clay Jenkinson, who has spoken as Jefferson in forty-nine states over a period of fifteen years, having performed before Supreme Court justices, presidents, eighteen state legislatures, and countless public, corporate and student audiences as well as appearing on The Today Show, Politically Incorrect, The Colbert Report and CNN. Clay is a humanities scholar, Rhodes Scholar, author and social commentator who is considered one of the most entertaining and articulate public speakers in the country.
Clay will be joining us again soon for Dead Presidents + Living Statues as we continue the conversation and talk openly about Jefferson's hypocrisy and the debate around statues in our country.
This program is part of the Created Equal and Breathing Free podcast series presented in partnership with Florida Humanities.
Find this event, including speaker bios, online at The Village Square.
