Climate is in any case the time average of weather, so if weather cant
be predicted, neither can climate


No. It's one of those things - more data, better modelling. Time gives
you access to more data. Not, of course, necessarily better models.



more data is good but you don't get more data over time for the weather
system. You still only have the same amount of valid data recorded by
the weather instruments even if you wait a day.
The problem with weather forecasting is not knowing the starting
conditions which makes it hard to model.
The best you can do is divide the planet into cells and fit some best
guesses into the cells based on nearby observations, nearby can be a
long way especially over the oceans.

Weather models are pretty good unlike climate models, weather models can
predict the future for a useful period.
Climate models have all failed to predict the future so are pretty
useless for actual science.
