Rising sea levels can submerge the backbone of the internet, increasingly powerful storms can destroy the cell networks phones need to work, and high-intensity winds can tear down the critical infrastructure that makes 21st century America go.
Anticipating accelerating climate change-fuelled disasters in the coming decades, telecommunications giant AT&T recently partnered with Argonne National Labs to build a three-decade model called a “Climate Change Analysis Tool” to help forecast the devastating impact of climate change on the company’s infrastructure and business on a level that details down to the individual neighbourhood.
Extreme weather that results from climate change has a direct impact on the bottom line of giant companies like AT&T when physical infrastructure is destroyed. In the last three years, AT&T has spent $1,182 billion on disaster recovery according to Fast Company.
While casting doubt on climate change has become a mostly right-wing politically polarising tactic around the western world, the global scientific consensus has long been that human activity is driving climate change. It’s not a theoretical idea: 2018 was the fourth-warmest year on record.
The five warmest years ever have been the last five years. Eighteen of the 19 warmest years ever have occurred since 2001. Climate change is real and it’s here now.
President Donald Trump has staked out a position as a climate change denier who, most recently, disbanded a group studying how climate change will impact the U.S. economy and risk American lives.
While Trump and a global band of right wing grifters use climate change as a political play thing, the president’s own Pentagon treats climate change as a national security threat and many of the country’s biggest companies are trying to figure out how to deal with how the increasingly extreme weather will hit their wallets.
AT&T, the world’s biggest telecom company, recently released a report titled “Road to Climate Resiliency” showing total damage to American infrastructure in 2017 added up to $427 billion, the worst year ever.
“The impacts of these types of events are only getting worse,” said Thomas Wall, a senior infrastructure and preparedness analyst at Argonne. “In 2017, in the United States, we saw 16 events that cost $US1 ($1) billion in losses or more. Around the world, it was 29 events. This is a significant increase over previous decades.”
The result is models and maps that outline potential disasters resulting from extreme weather and its consequences like flooding and high winds focusing in particular on the southeastern United States, a region regularly pummelled by extreme weather.
Argonne’s climate modelling data and mapping tools let AT&T look decades into the future of impending extreme weather and climate change-fuelled events like sea-level rise. The extreme weather is already here, now it’s a question of preparation.
A 2018 study found that over 6,437km of fibre optic cable buried along American coastline could be underwater by 2033, a number that will call into question internet access in coastal cities from New York to Miami.
The study warns that a 50-year storm in the southeast could mean 4.27m deep flooding in Georgia and South Carolina and wind speeds of 145km per hour across Southern Florida. Here’s a map from the collaboration:
The simulations were done on supercomputers like Argonne’s Theta computer which was previously used to map brain neurons and peering into particle physics. Theta is an 11.69 petaflop system, a measurement of speed that makes it one of the fastest machines on earth.
“Without supercomputers and the ability to do a lot of simulations very quickly, we really couldn’t do any of this work,” Wall said.
