Meanwhile, our prospective weather forecast is hotter, drier — and scarier. We’re already seeing dramatic changes in climate compared to the last century, according to the report. “Paleoclimate analyses and climate projections suggest persistent droughts and wet periods over the continental United States that are longer, cover more area, and are more intense than what was experienced in the 20th century. An evolving future, which can only be partially anticipated, adds to this risk.”

One thing seems clear: Climate change will further threaten our water. Higher temperatures will continue to increase the need for water, both because of human consumption and greater evaporation in farming. And that need will cause more people to tap into groundwater, which is already heavily depleted in parts of the country. Eventually, the report states, “increased future demand due to warming could exceed future supply in some locations.”

Asked about the climate assessment, which predicted that climate change will have severe impacts on the economy, Trump said “I don’t believe it.”

For those who do believe the science and are interested in mitigating the coming disaster, the report also includes a detailed road map for water management that recommends planning for a wide range of possible future climate conditions. The authors recommended updating policies using the best available science. Yet we’ll soon see the EPA do just the opposite.
