A problem without a solution is a poorly stated problem, said Albert Einstein.
Contrary to what many people think, global warming is not merely a problem. It is also a flurry of solutions and opportunities that have already popped out from civil society, from corporations, from institutions and from individuals as well. Some are well known, others less so; some are surprising, others are expected; some will have a global impact, others are of symbolic order; some are local, others will have a planetary reach.
