Climate of Hope

I am just reading the book Climate of Hope by Michael Bloomberg and Carl Pope. In this age that we, on the one hand, have leaders like Trump and Putin, who live in 1960's and say that human actions have no effect on world climate, and actually advocate the increasing use of fossil fuels - like clean coal, and on the other hand, have pessimistic climate prophets stating that world's end is looming, it is refreshing  to read a book that is optimistic and tries to find solutions. It is naturally so that we first need the pessimistic prophets to wake us up, but if nothing further is given, people just get depressed and do nothing, since the world is ending soon anyway. But there is reason for optimism: so far all the environmental problems have been solved. The silent spring has never come, the acid rain and smogs in Europe and North America have stopped, and the ozone hole is filling up. Since there are solutions also for climate change, why not be optimistic. And further, the solutions are such that economic activity increases and jobs are generated. They will not be generated in coal mines, but in producing windmills, solar panels, wave energy power plants, batteries for electric cars etc. Trying to push jobs into coal plants does not function, because they cannot produce energy as economically as the renewable energy power plants. So, instead of thinking that nothing can be done any more, let's allow the sun to shine, and optimistically do our own climate actions where we can. The climate of hope - for a good tomorrow.
