 . . . The increasing visibility of climate change, combined with bleak scientific reports and rising carbon dioxide emissions, is taking a toll on mental health, especially among young people, who are increasingly losing hope for their future. Experts call it “climate grief,” depression, anxiety and mourning over climate change.

New topographic and predictive rainfall data means more people in Harris County will be mapped in floodplains.

When Hurricane Harvey left so much of Houston underwater, it highlighted a problem that’s been getting worse for years: Harris County’s existing floodplain maps just don’t work.

In the year since the historic storm, flood control officials have promised to change that, and they already had plans to redo the maps, but new data on the geography of the area and the amount of rainfall forecasters expect in the future means the new maps could look drastically different.

It’s crucial the maps are done right, as people are using the maps, meant to set flood insurance premiums, for more than they are intended . . .

The catastrophic 2017 hurricane season – which included such monsters as Harvey, Irma and Maria – was fueled in part by unusually warm ocean water, a new study suggests.

And because of human-caused global warming, the study said similar favorable conditions for fierce hurricanes will be present in the years and decades to come . . .

 . . . "We show that the increase in 2017 major hurricanes was not primarily caused by La Niña conditions in the Pacific Ocean, but mainly by pronounced warm sea surface conditions in the tropical North Atlantic," the study said.
