It depends on what you want to impact. If you want to be in an area where somehow you'd get notoriety for contributing to mitigating clinate change disaster, you probably have a naive view of climate science research. However, if you basically just want to contribute in some small way by shifting what you're working on, and probably taking a 70% pay cut, then I'd recommend looking at academic labs. Lots of Uni research labs have lots of data being produced that needs to be hosted and made publicly accessible. This is essentially what I did for some time and it was very rewarding. In my case I worked on maintaining an open data portal based on CKAN, which hosted water water quality data as well as other data produced as a product of biology research.
