I used RCP 8.5, but tell us what that is.

Okay.

Yeah.

So that's the very phospho-intensive scenario that we think we're not on anymore, hopefully.

But those scenarios were developed – as you suggest, in a rather peculiar way in order to give possible ranges for models to be tested over.

They weren't intended as equally likely futures.

They weren't given probabilities, relative likelihoods, but they were seen as a way to span the range, and the range is still alive as far as I can tell.

we've had agency we've just had a sort of termination shock if you like of stopping doing something and there is now a growing amount of you know interest and research money going and it's still tiny but going into are there ways in which we could make the clouds brighter we could put back reflectivity in a less harmful way or a more efficient way um and what what are your views on this debate
