James Hansen's new climate warning and controversial planet-cooling plan
The renowned scientist argues that the world is warming faster than climate models predict, and is in favor of bold approaches to block some of the sun's rays.
Roads can be built on the moon, laser experiment shows
Constructing roads on the moon will be important for upcoming lunar settlements to mitigate issues with potentially damaging dust.
It's Too Late to Prevent Global Warming, but Maybe We Can Fix It
As more than 8 million people breathed—and saw—the air of New York City last week, climate change went from faraway abstraction to clear and present danger.
Firing moondust into space to create sun shield could combat climate change
The concept is purely speculative for now and would require overcoming huge obstacles, but scientists said the idea was "feasible" in theory.
China Has Started Geoengineering Rain Over Extreme Heat and Drought
The news comes as Cornell scientists say that geoengineering may be necessary to combat the effects of climate change.
Cold War Nuclear Bomb Tests Altered Rainfall Thousands of Miles Away
Discovery could have implications for future geoengineering research into influencing rain.
West Antarctic Ice Sheet Collapse Could Be Stopped With Artificial Snow
Without the ice sheet, sea levels are predicted to rise by over 10 feet.
Will Climate Change Wipe Out Humanity?
Food, payment and logistics systems are connected. If one starts crashing, the chaos may cause other systems to crash, and before we know it we'll have massive shortages and conflicts.
How We Can Remove Carbon From The Atmosphere
Climate intervention offers a grand challenge but can serve to offer a vision of the future that may bring global action.
Huge Artificial Wall Could Save Antarctica Glacier
Scientists propose radical geoengineering plan to slow down the collapse of ice sheets.
Terraforming Mars to Make It Habitable Won't Work
"[It's] not possible using present-day technology."
Scientists Have a Plan to Stop Hurricanes
By reducing the surface temperature of the ocean, in theory, man could stop hurricanes in their tracks.
Artificially Cooling Earth With Volcanoes Is Dangerous
Injecting aerosols into the atmosphere in the Northern Hemisphere would be disastrous for parts of Africa, scientists say.
How Can Scientists Engineer a Cooler Earth?
A risky geoengineering plan could tackle global warming without reducing emissions.
Geoengineering Won't Save Us From Sea Level Rise
A new study explains why geoengineering sea level rise would fail spectacularly.
What Experiments to Block Out the Sun Can't Tell Us
Using technology to fix climate change requires careful research—but that's easier said than done.
Diamond Dust in the Sky Could Cool Planet, Say Climate Scientists
But the cost—even if synthetic diamonds were used—could prove prohibitive.
Planet Reboot: Fighting Climate Change With Geoengineering
Scientists hope to wield the Earth itself as a weapon against global warming.
