Sending autonomous vehicles to the Southern Ocean can be fraught with anxiety, especially if one of them doesn’t make radio contact when it’s supposed to.
Lots of academic scientists collaborate with federal employees and resources on their research projects. And at the moment they can’t. A climatologist explains the bind they’re in.
Coastal real estate prices appear to be taking a hit, but mostly in neighborhoods with more climate change believers.
Saturated media coverage of hurricanes like Harvey and Irma can make it seem like disasters happen all the time. Is the frequency of billion-dollar disasters really rising?
