The Quest to Trap Carbon in Stone—and Beat Climate Change
On a barren lava plateau in Iceland, a new facility is sucking in air and stashing the carbon dioxide in rock. The next step: Build 10,000 more.

Is ‘hacking’ the ocean a climate change solution? U.S. experts endorse research on carbon-removal strategies.
The idea of hacking the planet to counteract climate change — a practice called “geoengineering” — is controversial in environmental circles. Many activists worry that the distant promise of unproven technological fixes distracts people from the emissions cuts that need to happen today.

Volcanoes and cooling:
The Next Big Volcano Could Briefly Cool Earth. NASA Wants to Be Ready.
"A quarter-century ago, Pinatubo, a volcano in the Philippines, blew its top in a big way: It spewed a cubic mile of rock and ash and 20 million tons of sulfur dioxide gas into the atmosphere. The gas spread around the world and combined with water vapor to make aerosols, tiny droplets that reflected some sunlight away from the Earth. As a result, average global temperatures dropped by about one degree Fahrenheitfor several years."
Solar geoengineering could be ‘remarkably inexpensive’ – report
IPCC authors suggest there is high agreement that injection of chemicals into stratosphere could help limit rises
- Full report: We have 12 years to limit climate change catastrophe, warns UN
-
The authors of the new 1.5C study by the Intergovernmental Panel on Climate Change say there is high agreement that the injection of millions of tonnes of sulphur dioxide into the stratosphere could help limit temperature rises to the most ambitious target of the Paris accord.
But the authors warn there are major uncertainties about the social, environmental and ecological impacts, which mean the world would be far better off if policymakers strengthened natural cooling systems such as forest cover and accelerated efforts to reduce carbon emissions.

Geoengineering may be used to combat global warming, experts say
"IPCC authors suggest there is high agreement that injection of chemicals into stratosphere could help limit rises
The world may increasingly look to geoengineering in the wake of the latest UN climate report, which says it could be adopted as a temporary “remedial measure” if the world heads towards dangerous levels of warming.
The authors of the new 1.5C study by the Intergovernmental Panel on Climate Change say there is high agreement that the injection of millions of tonnes of sulphur dioxide into the stratosphere could help limit temperature rises to the most ambitious target of the Paris accord.
But the authors warn there are major uncertainties about the social, environmental and ecological impacts, which mean the world would be far better off if policymakers strengthened natural cooling systems such as forest cover and accelerated efforts to reduce carbon emissions.
The lengthy document – which was approved at the weekend by all 195 nations in the UN – mentions several options for man-made interference in climate systems, including ocean fertilisation, carbon dioxide removal, marine cloud brightening, cirrus cloud thinning and ground-based albedo modification."

"There’s no planet B. But is there a plan B? Can we save ourselves from the worst effects of climate change? Ideas exist, but there’s no magic bullet – hacking the climate may cause more harm than good. We spoke to Riley Duren, a systems engineer based at NASA’s Jet Propulsion Laboratory (JPL), to get his take on the topic. Riley looks at how we can use observations of planet Earth to make better-informed responses to climate change."

Could spraying particles into marine clouds help cool the planet?
"The idea of geoengineering, also known as climate engineering, is very controversial. But as greenhouse gases continue to accumulate in our atmosphere, scientists are beginning to look at possible emergency measures.
A new University of Washington study looks at the idea of marine cloud brightening, which a UW group is investigating as a promising strategy to offset global warming. The strategy would spray saltwater into the air to make marine clouds reflect more incoming solar rays."

Not this group. “I don’t know how many times I have said this, but the last thing I would ever want is for the project I have been working on to be implemented,’’ Hunt said. “If we have to use these tools, it means something on this planet has gone seriously wrong.’’
