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.

 . . . “There is an increasing risk of two life-threatening impacts from Florence: Storm surge at the coast and freshwater flooding from a prolonged heavy rainfall event inland,” the National Hurricane Center wrote Sunday . . . We are particularly concerned about the rainfall potential in the Mid-Atlantic. Models have come into agreement that a northward turn before reaching the United States is unlikely and that a building high-pressure zone north of the storm will cause it to slow or stall once it reaches the coast or shortly thereafter.

Florence could sit over some part of the Mid-Atlantic for several days, similar to what Harvey did last year over eastern Texas. It has the potential to dump unthinkable amounts of rain over a large area in the Mid-Atlantic and perhaps into the Northeast. Rainfall could begin Friday or Saturday and continue into the following week. Where exactly the zone of heaviest rain sets up is a big uncertainty. It could reasonably occur anywhere between the mountains and the coast . . .

Some topics are so politically charged that even to attempt a discussion online is to invite toxicity and rigid disagreement among participants. But a new study finds that exposure to the views of others, minus their political affiliation, could help us overcome our own biases.

Researchers from the University of Pennsylvania, led by sociologist Damon Centola, examined how people’s interpretations of some commonly misunderstood climate change data changed after seeing those of people in opposing political parties.

The theory is that by exposing people to information sans partisan affiliation, we might be able to break the “motivated reasoning” that leads us to interpret data in a preconceived way.

The fires have scorched states from Washington to New Mexico, with California among the hardest hit

Six large new wildfires erupted in the United States, pushing the number of major active blazes nationwide to over 100, with more expected to break out sparked by lightning strikes on bone-dry terrain, authorities said on Saturday.

More than 30,000 personnel, including firefighters from across the United States and nearly 140 from Australia and New Zealand, were battling the blazes that have consumed more than 1.6m acres (648,000 hectares), according to the National Interagency Coordination Center . . .
