The award-winning atmospheric scientist on the urgency of the climate crisis and why people are her biggest hope

The coral reef crisis continues thanks to threats like climate change and pollution. With that in mind, the National Academy of Sciences released a major report last week detailing the high-tech interventions that may be...

Governments charge ahead on engineering Earth’s climate, ignoring possible harmful effects Tim Ball and Tom Harris The latest Intergovernmental Panel on Climate Change (IPCC) Report said we have only 12 years left to save...

What could possibly go wrong~ctm From Eurekalert Public Release: 22-Nov-2018 IOP Publishing A program to reduce Earth’s heat capture by injecting aerosols into the atmosphere from high-altitude aircraft is possible,...

Solutions such as geoengineering will not make enough of a difference. By Steinar Brandslet The countries of the world still need to cut their carbon dioxide emissions to reach the Paris Agreement’s climate targets. Relying...

Guest essay by Eric Worrall Geo-engineering is worse than we thought. Not only would geo-engineering depress crop yields by starving plants of sunlight, it now looks likely any serious attempt to geo-engineer the climate...

From the European Geosciences Union and the “we can stop that glacier in its tracks, cold. Trust us.” department comes this wacky geoengineering idea. I think these folks don’t understand what the scope...

Guest essay by Eric Worrall I guess we should be grateful that this time someone noticed the problems BEFORE creating another climate policy driven global food shortage...

Life on planet Earth is struggling through an historically challenging era, thanks in no small part to the actions of our species. Some scientists have proposed labeling this period as the Anthropocene epoch due to the outsize...

An idea so bad, even Michael Mann realizes it’s a stinker. Sprinkling large amounts of salt into the atmosphere could stave off climate change, a group of researchers has proposed. They’ve suggested that, because...

Scientists around the world want to create a giant sunshade in the sky to help reverse climate change. "Solar engineering" involves spraying tiny reflective particles into the atmosphere to cool the Earth by reflecting and...

Could salt help soothe our climate woes? Senior scientist Robert Nelson of the Planetary Science Institute seems to think so. At a recent Lunar and Planetary Science Conference in Texas, Nelson suggested that sprinkling salt...

Guest essay by Eric Worrall Scientists have proposed pumping brine to refrigerate the bases of glaciers from a nearby volcano lair, and vast Arctic and Antarctic seawalls to prevent warm water from coming into contact with...

Guest essay by Eric Worrall A new study suggests spreading crushed volcanic rock across the world’s farmland would absorb enough CO2 to curb global warming, so long as a cost effective means to crush all that rock can...
