    Q&A: Climate Change, Drought and the Future

    “One of the ways that climate change is going to manifest is through warmer temperatures. … What we are seeing, in line with our projections, is that even if you assume constant precipitation, the temperature effects are so large that it is going to dry things out. This is going to have really big impacts…
