Blanketing the Antarctic ice sheet in artificial snow might sound outlandish. But could geoengineering help to counteract runaway climate change? One thing is clear: many of the ideas could be very risky.
New research suggests that unless we rapidly cut greenhouse gas emissions we will have to extract far more CO2 from the atmosphere than we are technically prepared for.
The melting of small ice shelves surrounding Antarctica could lead to even bigger melt of glaciers hundreds of kilometers inland, compounding sea-level rise.
Climate change is a global threat. So where to get the best perspective on the problem? Space! Scientists are monitoring Earth with satellites and running experiments in zero gravity to help save our fragile planet.
So far, the Antarctic was seen as relatively stable. But a new study suggests that climate change is affecting the polar region on a much larger scale than previously believed – which could have devastating consequences.
