Climate scientist and aviation fan ... Not afraid of contradictions !
Bon appétit 😄

A typical case of killing the messenger instead of fixing the problem. The international community will support GFDL as it is the leading institution on climate research.

I hope this report of UNESCO will lead to a better understanding by the society of the risk posed and trigger more research to better quantify the expected changes in water resources.

This will be an important conference!

Let the market punish those who are not exemplary Citizen 😄

How are you going to fly your bird without NOAA providing the observations and forecasts ? These people in charge have no idea what it takes to keep aviation (among other things !) functioning.

Thanks for the clarification

I think I saw your little bird when I landed in SYD yesterday 😀

If we don't stand up for science then truth has no meaning anymore !

That was a productive meeting!

An important seminar for the Land surface modelling community!

Welcome to BlueSky! GEWEX will hopefully also help society adapt to the water resources of a warmer climate by coordinating the scientific community.

Made me think why not develop some type of "Turing tests" for geophysical models (AI, parsimoneous or physical based)? There are a number of perturbations (like 2xCO2) where we know what the characteristics of the response should be on physical arguments.

Yes produce more high quality knowledge which will not be contradicted by facts down the road 😄

Should climate science not take pride in having provided society with very similar results for the last 30 years ? So it might be good enough to propose projections every 10 years, when our understanding has indeed progressed. Earth observation needs to be intensified to inform society and science.

It is going to be an issue that we cannot have the same numbers for the global water cycle : total precipitation, water discharge from the continents, total water mass, ... Our observing system is not to the level needed for these variables which are so critical for managing our resources!

Thanks for posting also on Blusky ...so I can finally ditch the network of that mad man !
