How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:

I've seen this in the USA too. A local water co-op put a 1.2MW array floating on top of one the municipal water reservoirs. Along with carport and building PV arrays, they offsets 50% of the electricity consumed by the facility.
Their floating array also offsets some water lost to evaporation, but its too early for measurable numbers on that front so far.
So, not enough roofs?
