Climate Crisis
This Canadian startup wants to make our buildings out of CO2
Carbon capture technology is here, but how do we make it feasible?
“Digital Earth” can simulate climate change down to the kilometer
Europe’s ambitious Destination Earth project aims to simulate climate systems — and human impact — to the kilometer.
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.
