The Supreme Court Is Bypassing Science—We Can’t Ignore It
The court’s exclusion of scientists from the environmental rulemaking process comes full circle as the EPA strips federal protections for wetlands.
Subsurface Oceans Could Boost Exoplanet Habitability
Researchers have shown that oceans buried below layers of ice are more common than previously thought.
Molten Meteorites Didn’t Deliver Earth’s Water
A new study has ruled out large, once-molten meteorites called achondrites as sources of Earth’s water.
Asteroid Impacts Could Have Warmed Ancient Mars
Hydrogen released during large impacts might have boosted Mars’s surface temperature above freezing for thousands or even millions of years, enabling liquid water to flow over the Red Planet.
Tonga Eruption May Temporarily Push Earth Closer to 1.5°C of Warming
The underwater eruption of Hunga Tonga–Hunga Ha‘apai sent megatons of water vapor into the stratosphere, contributing to an increase in global warming over the next 5 years.
U.S. Public Water Supply Is a Local Source of Phosphorus Pollution
Excess phosphorus may reach U.S. rivers, lakes, and groundwater through water main leaks and outdoor water use.
Silicate Weathering Throttles the Global Thermostat
The natural breakdown of some rocks sucks carbon dioxide out of the atmosphere. Knowing how quickly it happens could help scientists engineer solutions to the climate crisis.
Confronting Water Use and Heat Exposure in Urban Sustainability
A framework is proposed for urban forest management to mitigate heat exposure, lessen drought issues, and conserve water use for urban heat mitigation and resilience in environmentally stressed cities.
Monitoreando el agua en la columna eruptiva masiva del volcán de Tonga
La reciente erupción del volcán Hunga Tonga-Hunga Ha’apai arrojó aerosoles de sulfatos y una cantidad nunca antes vista de vapor de agua a la estratosfera.
