Wetlands, especially coastal salt marshes, provide crucial ecosystem services including biodiversity preservation, water regulation, carbon storage, and climate regulation. Human activities have degraded many of these ecosystems, but restoration projects, such as those at Cape Cod National Seashore, aim to rejuvenate affected marshes and restore their vital functions.
Corporate lobbying, sometimes viewed skeptically, is increasingly being considered as a useful tool for advancing science-based climate policies. The effectiveness of this strategy hinges on overcoming several challenges, including workforce mobilization and the powerful corporate interests that lobby against environmental action.
The “30 by 30” conservation movement aims to conserve 30 percent of the Earth’s land by 2030. California is among the first jurisdictions to implement a comprehensive 30 by 30 strategy and has invested $11 billion towards the effort. The movement focuses on protecting biodiversity, engaging local communities, and building resilient ecosystems, while also navigating challenges like land use conflicts and climate change adaptation.
Concentrated beer formulas that minimize water content and transportation emissions are reducing the carbon footprint of the beer industry. This groundbreaking approach presents an opportunity for both producers and consumers to make more environmentally responsible choices when consuming beer.
In an effort to combat the increasing use of non-recyclable plastics, Martin Bourque and the Ecology Center in Berkeley advocate for laws and programs that reduce plastic consumption. Their strategies, including a bag reduction initiative and a disposable foodware ordinance, have been adopted at state levels and by other cities.
Air travel accounts for about 2.5 percent of global carbon emissions. To reduce emissions from aviation, ZeroAvia is seeking to build the world’s first zero-emission passenger jet powered by hydrogen fuel, which offers three times more energy per kilogram than jet fuel and emits no toxic fumes when combusted. Hydrogen fuel’s higher energy density and capacity for consistent electrical power make it a promising potential energy source for aircraft.
How can insights from geophysics help us to make better use of rainwater? Geophysicists, like Stanford’s Dr. Rosemary Knight, can identify ancient, buried riverbeds called paleo valleys. We spoke with her about how such geologic structures can help us recharge aquifers deep below the Earth’s surface.
Electric motorcycles and battery swap technology can improve livelihoods and reduce emissions in Africa and around the world. Ampersand, an African electric vehicle company, provides affordable electric motorcycles (called “e-motos”) in East Africa and operates a convenient battery swap system. These e-motos are replacing polluting gas motorcycles with a cost-effective and environmentally friendly alternative.
The use of indigenous forest burning practices, also known as prescribed burns, can reduce the risk of severe wildfires and promote healthier habitats amid climate change. Bill Tripp from the Karuk Tribe discusses the importance of re-establishing these practices.
Young people worldwide, represented by organizations like Our Children’s Trust, are increasingly using litigation to force governments to take climate action. This trend is illustrated by notable cases like Juliana v. United States and Held v. Montana.
