The IPCC report is not "a complete joke". Nothing in it requires the invention of radical new technology. We're not talking about needing some kind of ATMOS silver bullet. The reality is that there's alot of work to implement it, and it may not get done on time, but it's also not impossible (yet).
The technical challenges of moving to a renewable energy economy are doable, it's the political problem of forcing entire sectors of the economy worth hundreds of billions of dollars to replace themselves or drop out of existence.
I am looking forward to the ride ahead - whether it's bumpy or far worse.
Hard work will be required from us as a society and personally as individuals.
