Many of these organisations, also funded by the EU or EU member states (17 are EU-based), are now suddenly in serious financial disarray. I doubt that the EU will react and these organisations are too small and too institutional to react much themselves. I know a couple of them (besides the IPCC, which we all know) and can confirm that they do great work.
