Hello and welcome to Degrees of Change, I am Callum Reid, and this is your Friday climate briefing with the panic removed. Three stories this week. The first is just a number, but it is a number that quietly changes how electricity grids will be built: grid batteries got cheaper again, by about 15 percent, and I will explain who notices that first. The second is a court case about a coastal road that a council decided to stop defending from the sea, and the question of who pays for that decision. The third is a dry spring in one of the wheat belts that feeds a good part of the world, and I have a farmer on the line who has already changed what she plants. Then we update the prediction ledger, where I check my own past claims. You are listening on Witspeak Podcasts.
