In Science magazine, scholars call for more comprehensive research into solar geoengineering

Two articles being published in Science magazine's influential Policy Forum this week argue for more and better social science research into the potential use of solar geoengineering to offset some of the global warming from ...

Catastrophic sea-level rise from Antarctic melting possible with severe global warming

The Antarctic ice sheet is much less likely to become unstable and cause dramatic sea-level rise in upcoming centuries if the world follows policies that keep global warming below a key 2015 Paris climate agreement target, ...

A sun reflector for Earth? Scientists explore the potential risks and benefits

Nine of the hottest years in human history have occurred in the last decade. Without a major shift in this climate trajectory, the future of life on Earth is in question. Should humans, whose fossil-fueled society is driving ...

Coral tells own tale about El Nino's past

There is no longer a need to guess what ocean temperatures were like in the remote tropical Pacific hundreds of years ago. The ancient coral that lived there know all.

Dust from a giant asteroid crash caused an ancient ice age

About 466 million years ago, long before the age of the dinosaurs, the Earth froze. The seas began to ice over at the Earth's poles, and the new range of temperatures around the planet set the stage for a boom of new species ...

Analysis of wildfire smoke will help calibrate climate models

Thunderstorms generated by a group of giant wildfires in 2017 injected a small volcano's worth of aerosol into the stratosphere, creating a smoke plume that lasted for almost nine months. CIRES and NOAA researchers studying ...

Finding the right 'dose' for solar geoengineering

One of the key misconceptions about solar geoengineering—putting aerosols into the atmosphere to reflect sunlight and reduce global warming—is that it could be used as a fix-all to reverse global warming trends and bring ...

Tracking the movement of the tropics 800 years into the past

For the first time, scientists have traced the north-south shifts of the northern-most edge of the tropics back 800 years, reports a University of Arizona-led international team.

Geoengineering: Blocking sunlight to cool Earth won't reduce crop damage from global warming

Injecting particles into the atmosphere to cool the planet and counter the warming effects of climate change would do nothing to offset the crop damage from rising global temperatures, according to a new analysis by University ...

Artificially cooling planet 'risky strategy,' new research shows

Proposals to reduce the effects of global warming by imitating volcanic eruptions could have a devastating effect on global regions prone to either tumultuous storms or prolonged drought, new research has shown.
