Do you work on lakes globally? Check out what is, to my mind, the most complete global database of lakes (~6M) and associated attributes, newly published in WRR. Also the basis for SWOT lake data. agupubs.onlinelibrary.wiley.com/doi/full/10....

Map of global lake distribution, colored by the number of SWOT overpasses per 21 day cycle. There are many lakes with a high number of SWOT overpasses at high northern latitudes, but there are also tens of thousands to more than a million lakes on every continent. Lakes are graphed by latitude and longitude on the edges of the figure.

As a climate scientist in the insurance industry, I sometimes worry that we spend too much time talking up our ability to model natural catastrophes, and not enough about how the future insurance will be shaped by climate change.

www.nature.com/articles/d41...

Climate change will send home insurance spiralling. Here’s how to control costs

Insurers rely on sophisticated catastrophe modelling to estimate risk exposure — and as climate risks are rising, so are the costs for protection.
