As global greenhouse emissions rise, scientists want
to research the possibility of engineering the climate to avoid the
worst impacts of global warming.
But the public has so far been wary of such schemes. So the
so-called geoengineers are planning to make a declaration they hope
will be the first step to getting a "social license" to
The world's most prominent geoengineering researchers are
meeting in Berlin this week to discuss the the field's progress.
Attendees have been asked to provide feedback on a draft document
the Berlin Declaration, released by
VICE this morning.
It seeks to clarify geoengineering's governing principles, and
quell public concerns. But does it go far enough?
A lot of climate engineering sounds a bit sci-fi - from drawing
carbon dioxide out of the oceans by dumping iron filings in the
sea, to putting mirrors in space to reflect sunlight away from
earth. We've gone into much more detail, here.
The Intergovernmental Panel on Climate Change (IPCC) takes
geoengineering seriously, even if it gets a relatively small amount
of attention in its reports. The panel is also eager to
emphasise the technique's risks.
