More than 50 countries around the world have pledged to become net zero. But what does net zero actually mean—and is it achievable?
Race-based medical practises are being challenged more and more, as it becomes increasingly clear they have little basis in science.
The team finds out why adjustments for race and ethnicity are still being made in medicine, despite the potential harm and healthcare implications they cause. It’s been a massive week for the future of space tourism – the team shares a clip of a very excited Richard Branson who’s recent journey into microgravity has set the stage for the launch of Virgin Galactic’s first commercial space flights. The team gives an update on the dramatic heatwave ravaging the US, as more record high temperatures are set, continuing to leave destruction in its wake. They also explain what ‘impact gardening’ is and why it might help us find alien life on Jupiter’s moon Europa, and they share important news on the state of the cosmetics industry in Neolithic times. On the pod are Rowan Hooper, Chelsea Whyte, and Layal Liverpool.
Watering the Country’s Food Basket Is Becoming a Challenge
Droughts are part of a natural cycle of water. But the drought currently gripping the Western U.S. has climate scientists concerned that the cycle may be shifting. This has major implications for those who rely on the water the most: farmers and the communities they surround. Photo Illustration: Carter McCall/WSJ
Each year, California and the Southwest break new records for droughts and high temperatures, leading to heat waves, wildfires, and even flooding. Learn how these catastrophes operate together—and how engineers are working on new technologies to help us survive.
With records broken in Portland, Eugene and Seattle, the Pacific Northwest is sweltering under triple-digit temperatures the likes of which has never seen before in the normally temperate month of June. Lilia Luciano reports. Jeff Berardelli also joins “CBS This Morning” to discuss more.
In 2019, Cyclone Idai devastated Mozambique’s port city of Beira. Many died and entire neighborhoods were flooded. The city is now setting up large green areas designed to absorb future floodwaters. But entire fishing communities need to relocate.
Energy usage by large, old buildings like the Empire State Building represents a huge obstacle to cities’ dreams of carbon neutrality. New York City’s buildings account for 70% of its carbon emissions, for example, and half of those emissions are produced by the largest 5% of its structures. But retrofitting old buildings to make them more energy efficient represents a formidable challenge, both from an engineering perspective and in terms of convincing owners that doing so is in their financial interest.
With global temperatures rising the threat of a climate crisis has never been closer. From carbon capture to driverless cars, these cutting-edge technologies have the promise to help us fight the impending climate crisis.
In Kenya’s Rift Valley, climate change has brought an unprecedented increase in annual rainfall over the past several years, drowning pastureland, farms, homes, schools, churches, clinics and businesses.
The Great Rift Valley is part of an intra-continental ridge system that runs through Kenya from north to south. It is part of the Gregory Rift, the eastern branch of the East African Rift, which starts in Tanzania to the south and continues northward into Ethiopia. It was formed on the “Kenyan Dome” a geographical upwelling created by the interactions of three major tectonics: the Arabian, Nubian, and Somalian plates. In the past, it was seen as part of a “Great Rift Valley” that ran from Madagascar to Syria. Most of the valley falls within the former Rift Valley Province.
