Climate Crisis
Predator drones are using AI to create faster fire maps
The National Guard has used drones to create forest fire maps since 2017. New AI upgrades could make the maps in minutes, not hours.
Can trillions of reflective glass beads save arctic sea ice?
Arctic sea ice is more than majestic; it also reflects the sun’s rays. But young, thin ice melts fast. Can silica powder reflect enough sun to help it survive?
Doctors fighting deadly climate change
In partnership with Skoll Foundation
These doctors are coming together to address their collective carbon footprint, explore new solutions, and improve sustainability in healthcare.
Cooling the planet with a giant solar umbrella
Solar geoengineering would cool global temperatures — is it worth it?
Could a Norwegian “hurricane net” stop storms by cooling the sea?
Norwegian company OceanTherm uses bubble nets to keep ice out of fjords. Could a hurricane net weaken the storms?
Raising Pacific islands to save them from high sea levels
The president of Kiribati announced a new plan to fight against sea level rise: raise the islands.
Fertilizer feeds half the world. Can we make it without fossil fuels?
Fertilizer is needed to feed the world, but its production comes with a carbon footprint. This solar-powered strategy may reduce that.
Sending heat to space to reverse global warming
This high-tech material could reverse global warming by using radiative cooling to lower the Earth’s rising temperature.
A new approach to green building could reverse climate change
The building sector is one of the biggest contributors of greenhouse gas emissions. But new research suggests that trend could stop, and even reverse because of a new type of green building.
The hidden history in the Notre Dame attic
Studying the scarce, centuries-old logs that remain from the Notre Dame attic will help scientists reconstruct medieval climate data to see if temperatures were ever this high.
