But all of that stone emits heat and does nothing to absorb rain, and temperatures and flooding in the posh Italian city are only predicted to increase in the coming decades.   In Jakarta, black floodwaters already rush into homes every winter along the Indonesian city's many rivers. That water is filled with sewage and harbors disease, but many people can't afford to move. Soon, climate change will put more of Jakarta — and many other low-lying cities — below sea level.   And in arid San Diego, water is already treated like a precious commodity. As drought increases in the coming years, protecting this resource will become even more important.   Human-caused climate change is transforming weather patterns and shifting ecosystems around the globe. Cities will have to respond, and some are already taking bold steps.   Each of these three cities offers a different roadmap for climate adaptation that has lessons for other places around the world. And while no single approach will be a silver bullet, each offers a hopeful vision of how we can learn to live and thrive on a warming planet.
