Huge mirrors that reflect the sun’s light back into space are one of a number of measures being considered to battle climate change.
Leaked papers from the UN science body have unveiled the measures being considered for ‘geo-engineering’, which will be discussed at a meeting in Peru next week.
Other measures detailed in the papers, seen by The Guardian, include producing lighter coloured crops and using iron filings in the world’s oceans.
The scientists involved in the proposals, which total around 60, other ideas include spraying sea water into clouds as a reflection measure as well as painting streets and roofs white.
However there is worry among these scientists that even if their plans do work they could cause irreparable damage due to uncertainty surrounding the technology.
