Weather and climate disasters cost U.S. a record $306 billion in 2017

BY ANDREW FREEDMAN2 DAYS AGO

A disastrous hurricane season combined with wildfires and other extreme weather events inflicted a record-setting toll on the U.S. in 2017, with 16 billion-dollar weather and climate events costing a total of $306 billion in damage. These events caused 362 direct deaths.

These figures come from a new report from the National Oceanic and Atmospheric Administration (NOAA), released on Monday morning.

The previous costliest year for the U.S. was 2005, when losses totaled $215 billion, largely due to the three major hurricane strikes of Hurricanes Katrina, Rita, and Wilma.

The number of billion-dollar events tied 2011 for the most such disasters in a single year. The Western wildfire season alone, which scorched California in particular, cost at least $18 billion, NOAA said, tripling the previous record annual wildfire toll.

increasing frequency of some types of extreme weather that lead to billion-dollar disasters," wrote Adam B. Smith of NOAA in a blog post. "Most notably the rise in vulnerability to drought, lengthening wildfire seasons and the potential for extremely heavy rainfall and inland flooding events are most acutely related to the influence of climate change."

There is some uncertainty associated with the billion-dollar event estimates, given that NOAA is drawing from about a dozen databases, from private insurance company figures to public data from the federal government. The costs do not include ancillary costs of these events, such as health care, including mental health care that may be needed for storm survivors for years after an event.

Furthermore, the death toll from Hurricane Maria is still being tabulated, as are the costs, so these figures are likely to be updated in the future.

"They really are a low point to the true costs that are probably harder to calculate," Smith said during a press conference from the American Meteorological Society annual meeting in Austin, Texas.

Third-warmest year for the U.S.

The NOAA report also found that 2017 was the third-warmest year on record for the lower 48 states, with an average annual temperature that was 2.6 degrees Fahrenheit above the 20th Century average. This was slightly cooler than 2012 and 2016, but it marks the 21st straight warmer-than-average year for the country.

In other words, if you were born in the U.S. in 1997 and remained here since, you've never experienced a cooler-than-average year in the U.S. In fact, the globe has not experienced a cooler-than-average month since December of 1984.

Strikingly, the five warmest years on record for the contiguous U.S. have all occurred since 2006, NOAA found.


This year, every state across the lower 48 and Alaska had an above-average annual temperature, and five states — Arizona, Georgia, New Mexico, North Carolina, and South Carolina — had their warmest year on record. This is the third-straight year in which every state across the lower 48 states has had an above-average annual temperature, said Jake Crouch, a climate scientist at NOAA's National Centers for Environmental Information in Asheville, North Carolina.

Thirty-two additional states, including Alaska, had a top-10 warmest year.

One way that NOAA measures extreme weather is via the Climate Extremes Index, which takes into account temperatures, precipitation, tropical storms and hurricanes, and other factors. In 2017 it had the second-highest value in the 108-year period of record, which was more than double the average.

Only 2012 had a higher value on this index, NOAA said. Extremes in warm maximum and minimum temperatures, one-day precipitation totals, days with precipitation and landfalling tropical cyclones contributed to the elevated extremes index, NOAA found.

According to NOAA, during the past 38 years, the U.S. has sustained 219 weather and climate disasters where the overall damage costs reached or exceeded $1 billion. The cumulative costs for these 219 events exceed $1.5 trillion, when adjusted to current levels using the Consumer Price Index.

This story has been updated to state more explicitly that some of the billion-dollar events may have some climate change connection to them.

Do you guys care? Have you been personally effected by the storms this year?

SEA LEVEL RISE IN THE SF BAY AREA JUST GOT A LOT MORE DIRE

IF YOU MOVE to the San Francisco Bay Area, prepare to pay some of the most exorbitant home prices on the planet. Also, prepare for the fact that someday, your new home could be underwater—and not just financially.

Sea level rise threatens to wipe out swaths of the Bay's densely populated coastlines, and a new study out today in Science Advances paints an even more dire scenario: The coastal land is also sinking, making a rising sea that much more precarious. Considering sea level rise alone, models show that, on the low end, 20 square miles could be inundated by 2100. But factor in subsiding land and that estimate jumps to almost 50 square miles. The high end? 165 square miles lost.

The problem is a geological phenomenon called subsidence. Different kinds of land sink at different rates. Take, for instance, Treasure Island, which resides between San Francisco and Oakland. It’s an artificial island made of landfill, and it’s sinking fast, at a rate of a third of an inch a year. San Francisco Airport is also sinking fast and could see half its runways and taxiways underwater by 2100, according to the new analysis.

Now, subsidence is nothing new to climate scientists. “People have been aware that this is an issue,” says UC Berkeley’s Roland Burgmann, coauthor of the paper. “What was missing was really data that has high enough resolution and accuracy to fully integrate” subsidence in the Bay Area.

To get that data, the researchers took precise measurements of the landscape from lidar-equipped aircraft. They combined this with data from satellites, which fire radar signals at the ground and analyze the return signals to estimate how fast land is moving either toward the spacecraft or away from them.


By comparing data from 2007 to 2011, the team showed that most of the Bay’s coastline is subsiding at a rate of less than 2 millimeters a year. Which may not seem like much, but those millimeters add up, especially considering a study that came out last month suggested sea level rise is accelerating.


"You talk to someone about, Oh the land is going down a millimeter a year, and that can be kind of unimpressive," says the University of Nevada Reno's William Hammond, who studies subsidence but was not involved in the study. "But we know as scientists that these motions, especially if they come from plate tectonics, that they are relentless and they will never stop, at least as long as we're alive on this planet."

Speaking of being alive on this planet: Humans have induced subsidence at an astonishing scale by rapidly depleting aquifers. Take the South Bay, for instance. “Parts of San Jose have been lowered up to 12 feet due to groundwater extraction,” says USGS coastal geologist Patrick Barnard. Fortunately, the extraction policies that led to those losses are kaput. But the same can’t be said for the rest of the planet, in particular for communities that are suffering drought exacerbated by climate change.

“It's not a major concern for the Bay anymore,” Barnard adds, “but it is for in general aquifers worldwide, especially in developing countries where a lot of groundwater is extracted from these large river deltas where millions of people live. They're already extremely vulnerable to sea level rise.”

The developing world is nowhere near ready to deal with subsidence and rising seas, but neither is the developed world. This is a problem that defies human ingenuity. It’s not like the San Francisco Bay Area can build one giant sea wall to insulate itself. And it’s not like low-lying Florida can hike itself up, or New York City can move itself inland a few hundred miles.

“There is no permanent solution to this problem,” says Arizona State University geophysicist Manoochehr Shirzaei, lead author of the paper. “This will impact us one way or another. The forces are immense, it's a very powerful process, the cost of really dealing with it is huge, and it requires long-term planning. I'm not so sure there's a good way to avoid it.”

Save for keeping seas from rising in the first place. That, of course, would require a tremendous global effort to cut back emissions. But even conservative projections suggest future sea level rise could be dramatic. Which means we as a species have to seriously reconsider the idea of a coastal town, or in case of the Bay Area, a sprawling coastal metropolis. Because the sea is coming to swallow us, and there’s nothing we can do to stop it.
