Rooftop solar panels are nearly 80 percent cheaper than they were just 10 years ago. A new paper says that if we installed them on 50 percent of roofs, we could meet all the world's yearly electric needs.
A July study found that every coastal estuary could prevent $38 million of damage from major storms like Hurricane Ida. But that means wetlands need protecting, too.
Purdue University researchers have developed an ultra-white paint that reflects more than 98 percent of sunlight and could reduce the need for energy-consuming air conditioning.
The controversial technology of reflecting sunlight away from the planet could help blunt the worst impacts of climate change. Harvard University climate scientist David Keith weighs in.

Kernza is a wheat-like grain that doesn't have to be replanted each year, making it the ideal crop to aid in the fight against climate change and help to feed the world.
These new devices may be used in the future to absorb more of the sun's energy than today's solar panels are capable of collecting.
In Africa's Ivory Coast, a group of women saw a need and came together to collect plastic for recycling into bricks to build schools.
There are seven different numbers you might see on a plastic container. And each number has its own meaning.
Coral grows faster when it's cut or broken and scientists are taking advantage of that to replenish depleted reefs.
There's no easy fix for climate change so scientists are playing with altering the Earth's natural systems in hopes of slowing it down. What could possibly go wrong?
Human attempts to alter the Earth's natural systems could either successfully avert climate change or fail and cause even greater harm.
In Colorado, a recycling robot uses artificial intelligence to sort through discarded cartons more efficiently.
China, the world's largest emitter of CO2, is making steps to combat those emissions by creating the world's largest floating solar panel farm.
