End of Eternity

From Big Picture Science | Part of the Big Picture Science series | 54:00


Nothing lasts forever. Even the universe has several possible endings. Will there be a dramatic Big Rip or a Big Chill­–also known as the heat death of the universe–in trillions of years? Or will vacuum decay, which could theoretically happen at any moment, do us in? Perhaps the death of a tiny particle – the proton – will bring about the end.

We contemplate big picture endings in this episode, and whether one could be brought about by our own machine creations.

231208: Reporting from COP28: The People at the Heart of It All, 12/8/2023

From Climate One | Part of the Climate One- Weekly Feed series | 58:57


We’re a week into the 28th Conference of the Parties, the UN’s annual climate summit, held this year in the city of Dubai. This year is the “global stocktake” where countries are supposed to show how far they’ve come in meeting the carbon reduction targets they set in Paris seven years ago. And the news isn’t good.

“Countries are still failing,” says Claire Stockwell, senior climate policy analyst at Climate Analytics, and lead author on the latest report from Climate Action Tracker, the premier, independent body for comparing how promises stack up against reality. 

“The targets and actions the governments put on the table have stalled. It's essentially the same report we put out three years ago in Glasgow. And so we need, at this meeting, governments to commit to a lot more ambitious action and targets, and that's going to start with making sure that in the final decision they agree to phasing out fossil fuels.”

So far more than 100 countries have called for an immediate end to all new oil and gas production and clear end dates for fossil fuel production. And more than 110 countries have pledged to triple renewable energy capacity and double energy efficiency by 2030. 

The leaders of the two biggest emitters, the U.S. and China, are notably not attending this year, though both countries have high-level representatives at the summit. 

We spent a good portion of our show last week on the controversy around Sultan Al Jaber as COP28 president. And it seems like the fossil fuel industry has a larger presence at this conference than ever before. The CEO of ExxonMobil came to one of these conferences for the first time. 

There has been some progress from the industry, though far from enough: ExxonMobil and Saudi Aramco — two of the world's biggest oil companies — are leading a pledge to reach near-zero methane emissions by 2030. They've gotten dozens of other companies to sign on to it. And there's a satellite that will actually measure the leaking, to keep them honest.

Last year at COP27, one of the biggest outcomes was the creation of a loss and damage fund for rich nations to help pay poorer countries for the climate impacts their emissions have caused. As of this writing, country pledges are over $700 million, a bright spot in the early part of the conference.  

This week we’re featuring a few of the thousands of people who have traveled to COP28 to share their stories and pressure heads of state to be more aggressive in cutting climate-harming emissions. Those include a woman from Sudan who fled armed conflict with her baby, a Kenyan woman haunted by seeing animal carcasses by the side of the road in her country, and an Indigenous woman who did a crowdfunding campaign to get here. 

“The young generation is not the generation that caused climate change. But it's the generation that will have to deal with the [con]sequences of climate change. Yet we are not the ones making the decisions,” says Sudanese Climate Activist Nisreen Elsaim. 

These women have traveled thousands of miles to this UN climate summit in Dubai to share their experiences — and have their voices heard.

“Representation of Indigenous people is always a good thing, but it's not enough. I should be included for participation. I should be included to make sure that my demands are being heard. And I should be included to make sure that the next generation are also at the table,” says Chautuileo Tranamil, co-founder of Indigenous Liberation and Aralez.

Marine Biomimetics, part two

From World Ocean Observatory | Part of the World Ocean Radio series | 05:07


In these three episodes of World Ocean Radio we are exploring a recent publication entitled “A Forgotten Element in the Blue Economy: Marine Biomimetics and Inspiration from the Deep Sea,” authored by Robert Blasiak from the Stockholm Resilience Center in Sweden. The article identifies seven broad categories of biomimetic design: adhesion, anti-fouling, armor, buoyancy, movement, sensory, and stealth. In this 3-part series we'll discuss each with examples of application, technological invention, and as effective solution models for response to negative human intervention and climate change, and for ocean protection and conservation.

103jason_mclennan_2022_a1_0705_small What would it feel like to live in a world where our built environment was as elegant as nature's designs? What if our living and working spaces nurtured our human communities and quality of life? Architect and designer Jason F. McLennan takes the revolution from the heart of nature and the human heart into our built environment. He is shifting the fateful civilizational inflection point we face - from degradation to regeneration - from fear to love.

521: Lowering Barriers to Care, 12/8/2023

From WHYY | Part of the The Pulse series | 59:00

3000x3000_itunes_thepulse_1_small Lots of things can get in the way of taking care of your health, catching medical issues early on, and getting treatment. Navigating insurance woes, trouble scheduling appointments, big medical bills — but also broader issues like lack of access, distrust in the medical system, and language barriers can stand in the way of patient care. On this episode, we’ll take a look at barriers to health care — especially for America’s most vulnerable populations — and explore potential solutions. We hear stories about a new initiative to screen for colorectal cancer, how AI is helping to bridge language divides, and a recent push to institute screenings for the forgotten sense.

Constant Wonder - Eat, Poop, Die

From BYUradio/KUMT/KBYU-FM | Part of the Constant Wonder series | 52:50


Sixty years ago, the island of Surtsey was born of a volcanic eruption. It would've remained a bleak, barren place were it not for bird droppings which created a tiny ecosystem in which plants, insects, and birds now thrive. It's a compelling example of the way that animals distribute nutrients around the globe through their poop. In other instances, carcasses nourish many forms of life around them, especially during and after a migration. In this episode, we'll find wonder around the world in quite unlikely places.
