Another day, another story about what we should consume when confronted with a water-scarce future. On today’s chopping block: Lettuce, should you eat it?

Greenland's Ice Sheets Are Getting Cooked By Warm Ocean Currents

The retreat of Arctic sea ice has been so dramatic over the last few years that atlases are being changed. Now it turns out Greenland’s ice sheets are also melting faster than we thought — not on the visible surface, but due to currents deep below the ocean.

I Flew With NASA To Study The California Drought From The Sky

It didn’t look good. Dark sapphire pools dotted the bare grey peaks of the Sierras, ringed in too many concentric circles of sediment to count.
