Back in the late 1990s, Ken Caldeira set out to disprove the "ludicrous" idea that we could reverse global warming by filling the sky with chemicals that would partially block the sun. A few years earlier, Mount Pinatubo had erupted in the ...
Not long ago, my newspaper informed me that glaciers in the western Antarctic, undermined by the warmer seas of a hotter world, were collapsing, and their disappearance “now appears to be unstoppable.” The melting of these great ice sheets would ...
Former U.S. vice-president Al Gore pulled no punches about geoengineering
in a phone conference with reporters on Wednesday. He was apparently reacting to a suggestion in a leaked draft summary of the forthcoming climate solutions section of the ...
The debate comes down to which response is the most urgent and necessary reaction to climate change.
Climate change is reversible and can be solved through mitigation efforts. Adaptation strategies leave families and friends in lesser ...
Harvard's David Keith calls it the "goofy Goldfinger scenario' -- a rogue nation, or even an individual, would conduct an unsupervised geoengineering
experiment -- and he confidently predicted in a story I wrote last month that it would never ...
A human rights-based approach to science, technology and development seeks to place a concern for human rights at the heart of how the international community engages with urgent global challenges. It entered the UN's lexicon in 1997, with Kofi ...
Summer thunderstorms across the United States inject water vapour far higher into the atmosphere than was previously believed, promoting a cascade of chemical reactions that could pose an increased threat to Earth’s protective ozone layer as the ...
Martin Rees says nations should be "extremely cautious" about solar radiation management geoengineering
techniques, which also include the injection of sulphate aerosols into the stratosphere to cool the earth by mimicking volcanic ...
Intentionally messing with the world’s climate sounds like something only a comic book villain would do.
But in March, at an unprecedented conference in northern California, a group of climate scientists and officials from several ...
Some talk of hoisting mirrors into space to reflect sunlight, while others want to cloud the high atmosphere with millions of tonnes of shiny sulphur dust. Now, scientists could have dreamed up the most ambitious geoengineering
plan to deal with ...
-- the deliberate manipulation of climate to counteract global warming -- might not be taking off just yet, but the push to fund more research into it is increasing.
This week, Novim, a think tank based in Santa Barbara, ...
A proposal to place mirrors in the sky to reflect sunlight away from earth
won't give back the climate we had before, says a new study.
Researchers at the University of Bristol in the United Kingdom applied global
climate models ...
