Zoom in, and more pockets of concern emerge. States like New Mexico in the U.S. and cities such as Cape Town, South Africa — which nearly ran out of drinking water last year — have "extremely high" stress levels.

Where things stand: A dangerous combination of hot and dry weather, poor water management and rising demand is leaving cities including Chennai, India, and Harare, Zimbabwe, without water for days on end, Tanvi Nagpal of Johns Hopkins writes for Axios Expert Voices:

What to watch: The pressures on municipal water supplies are likely to worsen with the effects of climate change.

When Democrats next week formally nominate the daughter of an Indian immigrant to be vice president, it'll be perhaps the biggest leap yet in the Indian American community's rapid ascent into a powerful political force.

Why it matters: Indian Americans are one of the fastest-growing, wealthiest and most educated demographic groups in the U.S. Politicians work harder every year to woo them. And in Kamala Harris, they'll be represented in a major-party presidential campaign for the first time.
