Perhaps 5,000 people died in Puerto Rico in 2017 for reasons related to September's Hurricane Maria, according to a study that dismisses the official death toll of 64 as "a substantial underestimate."

A research team led by scientists at the Harvard T.H. Chan School of Public Health didn't simply attempt to count dead bodies in the wake of the powerful storm. Instead, they surveyed randomly chosen households and asked the occupants about their experiences.

From that approach, they concluded that between Sept. 20 and Dec. 31, 2017, there were 4,645 "excess deaths" — that is, deaths that would not have occurred if the island hadn't been plunged into a prolonged disaster following the devastating storm.

In the weeks before Hurricane Harvey tore across the Gulf of Mexico and plowed into the Texas coast in August 2017, the Gulf's waters were warmer than any time on record, according to a new analysis led by the National Center for Atmospheric Research (NCAR).

These hotter-than-normal conditions supercharged the storm, fueling it with vast stores of moisture, the authors found. When it stalled near the Houston area, the resulting rains broke precipitation records and caused devastating flooding.

"We show, for the first time, that the volume of rain over land corresponds to the amount of water evaporated from the unusually warm ocean," said lead author Kevin Trenberth, an NCAR senior scientist. "As climate change continues to heat the oceans, we can expect more supercharged storms like Harvey."

Figure 1: Distribution-scale solar costs more than wholesale power, but it costs less if you fairly value all benefits

“New Record Set for World’s Cheapest Solar.” A headline like this makes for great social media fodder. The downward trend in renewables prices is fantastic—it’s the most important driver for the growth of solar and wind energy.

However, when your business or utility is comparing different energy projects, looking at cost alone is not enough. Even energy projects at very low costs can be “out of the money” if the value created by a project is less than its cost.
