The National Security Threat that Inflicted 400 Billion in Damages This Year

Back in the 1990s, the U.S. Navy asked Congress to address the issue of rising sea levels at the Norfolk Naval Base. The Navy wanted to raise the piers, which were becoming vulnerable to flooding due to rising waters. For various reasons, including climate change denial, Congress has delayed funding for elevating the base’s 12 piers beyond the present and near term projected reach of ongoing sea level rise. Only four so far have been lifted.

According to former Norfolk Naval Base Commander Joe Bouchard, “Washington went bonkers” when it failed to recognize and address an obvious problem — sea level rise.

Up and down the U.S. coastline, the story is much the same. But it’s not just a case of Navy Base piers. It’s a case that every coastal city in the U.S. now faces rising seas threatening homes, real estate, infrastructure. And at the same time that seas are rising, the strongest storms are growing stronger and fire seasons that once ran through a few months of the year in places like California are now a year-round affair.

This is the very definition of climate change as a threat to the security, not just to the world’s largest naval base, but to most if not all of the United States.

So how bonkers is Donald Trump and the climate change denying GOP now? How nuts is it that Trump yesterday made the anti-factual determination, in bald defiance of a plethora of U.S. military leaders, that “climate change is not a national security threat?”

Increasingly Destructive Hurricanes are Putting a Growing Number of People and Structures at Risk

This year, the U.S. has experienced not one, not two, not three, not four, but at least five major weather disasters that were made much worse by human-caused climate change. Three of them — hurricanes Maria, Irma, and Harvey all roared out of a warming ocean. They all formed in a hotter atmosphere loaded up with a higher level of moisture. These factors gave them more fuel to feed on. They unarguably increased their peak potential intensity. Scientific studies have found that Harvey alone was three times more likely to form due to human-caused climate change. That its rainfall was considerably enhanced in a warmer atmosphere.

The storms ran in to land on a higher ramp. Seas, like those at the Naval Base and in so many other places, have risen by a foot or more from the Gulf Coast to New England and on into the Caribbean because the Earth has, indeed, warmed. And this made storm surge impacts worse.

You could go on and on with the list of climate change related factors that compounded this year’s disasters. About the climate zones moving north. About hot blobs in the ocean and bigger blocks in the atmosphere. About enhanced convection and ice cliff instability. About ridiculously resilient ridges and persistent troughs. But it’s just a simple fact that the storms were worse than they would have been. That climate change made them more likely (in some cases far more likely) to occur in the first place. In total, and in large part due to the nefarious influence of fossil fuel burning on the world’s weather, these three storms alone have inflicted 368 billion dollars in damages.

That’s billion with a capital B. A level of harm often attributed to warfare but one that can instead be put at the feet of weather indiscriminately weaponized by fossil fuel burning. For the Atlantic Hurricane season this year, at a time when global temperatures are 1.1 to 1.2 C hotter than 1880s averages, was the most destructive ever recorded.¬†These climate change enhanced storms left whole island nations and entire regions in ruins. In many cases it will take months, years, or even a decade or more to fully recover.

Wildfires are Increasing and Wildfire Season is Getting Longer in the Western U.S.

But in the grim tally of climate change related damages during 2017, we don’t stop at just hurricanes. For California, during 2017 experienced its worst fire season on record. One in which 11,306 structures have so far been damaged or destroyed. We say so far because what is likely to become the largest fire in California history — the Thomas Fire — is still burning.

11,306 structures would be enough to make a decent sized city. All gone due to a fire season that is now year round. Due to western heating, drying and temperature extremes that are increasingly forced to well outside the normal range. Total damages this year for California are presently estimated at more than 13 billion dollars. That’s nothing to shake a stick at. But this damage total is likely to continue to climb as the tally of losses is counted.

As with hurricanes, the presently more intense fires are linked in numerous ways to a warming climate. Warmer temperatures increase the rate of evaporation and the intensity of precipitation in the most extreme events. Such variance increases the rate at which vegetation grows during wet season and the rate at which it dries during times when the rains depart. This adds more ready fuels for fires. In addition, northward movement of the Arctic sea ice contributes to an overall warmer and drier pattern for the U.S. West. This pattern, helps to produce stronger high pressure systems that, in turn, strengthen the fire-fanning Santa Ana winds.

This year, December, which is typically a wet month for the U.S. West, especially during La Nina (which we are presently experiencing) has been incredibly dry. This dryness helped to fuel the Thomas Fire. But the dryness didn’t happen in a vacuum. It was associated with a major climate change related influx of heat into the Arctic linked to climate change driven polar amplification.

Failure to Recognize Climate Change Leaves U.S. Citizens Vulnerable to Harm

Anyone following the increasingly clear evidence of how Trump campaign officials coordinated with Russia to disrupt the 2016 elections and how ardently Trump is attempting to cover the whole thing up could draw the reasonable conclusion that Trump cares more about his own personal advancement than the safety and security of the American people. Trump’s, and by extension, the GOP’s climate change denial, can be seen through the same morally relativistic lens. Wealthy fossil fuel donors have for a long time now held an unreasonable influence over persons in higher office. The denial of climate change for both the Republican Congress and the Presidency is, in other words, well-funded.

(GOP funding by fossil fuel donors just keeps going up and up in lockstep with GOP climate change denial and anti-environmental policy. Image source: InsideClimate News.)

Such denial may line the pocketbooks of republican politicians and wealthy oil, gas, and ailing coal companies. But it places the American people, their homes, their livelihoods, beneath the blade of a falling ax. So when Trump says climate change is a hoax, forces government websites to shut down, scrubs words related to climate change from government communications, opposes alternative clean energy, and tells the Department of Defense not to treat climate change as a national security threat, he is culpable and a contributor to a very clear, present, and growing danger.
