Science Senior Correspondent Daniel Clery regales host Sarah Crespi with tales about the most important work to come from 57 years of research at the now-defunct Arecibo Observatory and plans for the future of the site.
Sarah also talks with Toman Barsbai, an associate professor in the school of economics at the University of Bristol, about the influence of ecology on human behavior—can we figure out how many of our behaviors are related to the different environments where we live? Barsbai and colleagues took on this question by comparing behaviors around finding food, reproduction, and social hierarchy in three groups of animals living in the same places: foraging humans, nonhuman mammals, and birds.
When Covid-19 sparked lockdowns around the world, emissions of one of the greenhouse gases responsible for climate change, atmospheric carbon dioxide, plummeted. But is this record drop a short-term effect of the 2020 pandemic or a ‘new normal’? BBC Weather’s Ben Rich explores the impact of coronavirus on the global climate.
Despite overwhelming scientific evidence, some American politicians continue to deny that climate change exists, while others question the severity of its impact. But public opinion is shifting, and today even oil and gas companies publicly admit that climate change demands action. So why does climate denialism continue to influence U.S. politics? Here’s a look into who is funding the movement, and why denial is mainly a U.S. problem.
A Perfect Planet is an awe-inspiring exploration of Earth’s power and fragility.
Planet Earth is perfect. It orbits at the perfect distance from the sun; it tilts at just the right angle and has a decent sized moon to hold it in place. On top of that, the day-to-day workings of the planet naturally serve to nurture animals and plants.
This five part series will show how the forces of nature – weather, ocean currents, solar energy and volcanoes – drive, shape and support Earth’s great diversity of life. In doing so, it will reveal how animals are perfectly adapted to whatever the environment throws at them.
With a lack of restrictions on water use, owners of some large-scale farms in the United States are drying up underground water tables. All they have to do is buy the land to have access to as much free water as they want. In Arizona, farm owners and ranchers are digging ever deeper to irrigate their land, leaving other residents with low water reserves. Meanwhile, parts of the land have caved in, collapsing as the water is pumped up from beneath. Our France 2 colleagues report, with FRANCE 24’s James Vasina.
Alan Watson Featherstone, ecologist and founder of “Trees for Life,” describes the moment he realized he needed to help in the effort to rewild Scotland, resulting in the founding of his charity “Trees for Life” to achieve this.

Mining companies and governments will soon be allowed to extract minerals from the deep-ocean floor. These rare metals are vital for a more environmentally sustainable future on land, but at what cost to the health of the ocean?
On Sept. 15, 2020, Arctic sea ice reached its annual minimum extent — the second-lowest on record. This summer, temperatures soared in the Siberian Arctic, and intense fires burned through peatland. The Arctic region is warming three times faster than the rest of the planet.
Global satellite data indicate wildfires are becoming bigger and more intense. WSJ talks with NASA’s Doug Morton to understand the science behind what’s making the planet more flammable and making fires harder to control.
