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.
Climate Extremes Threaten California’s Central Valley Songbirds
A “nestbox highway” in California’s Central Valley is guiding songbirds to safe nesting sites and giving scientists a peek at fledgling success in a changing climate.
Protecting Poor Neighborhoods from Landslide Risk
As low-income, informal settlements bloom in the tropics, their risk of landslides increases. A new modeling tool incorporates urbanization factors to protect the region’s poorest neighborhoods.
After a Hurricane, Coastal Systems Draw a Line in the Sand
A new study finds nature can’t have it both ways: On the basis of thousands of case studies from dozens of hurricanes, there’s always a trade-off between resistance and resilience.
Cuando los ríos están contaminados, las inundaciones son solamente el primer problema
A medida que las inundaciones aumentan en frecuencia e intensidad, los productos químicos enterrados en los sedimentos de los ríos se convierten en “bombas de tiempo” que esperan activarse.
Africa’s Earth, Wind, and Fire Keep the Amazon Green
Jet streams sprinkle North African dust over the Amazon, providing the rain forest with much needed nutrients. Changing wind patterns and increasing smoke may shift the system.
At-Home Astronomers Help Discover a New, Unique Exoplanet
Amateur astronomers sifting through NASA’s public data uncovered a long-orbit gas giant that could help scientists understand how these planets form.
Una nueva herramienta crea rápida y gratuitamente mapas de inundaciones para el sur global
Un nuevo programa en línea puede trazar rápidamente los contornos de inundaciones pasadas, permitiendo que los países con escasez de datos se preparen para futuros desastres.
Supergreen Trees Can Signal Sites of Eruptions
Tree core chemistry can explain what happened before Mount Etna’s 2002 eruption and suggests that trees could play a role in rebuilding past eruptions.
