Irma and Harvey lay the costs of climate change denial at Trump’s door

The president’s dismissal of scientific research is doing nothing to protect the livelihoods of ordinary Americans

As the US comes to terms with its second major weather disaster within a month, an important question is whether the devastation caused by hurricanes Harveyand Irma will convince Donald Trump and his administration of the reality of climate change.

The president’s luxurious Mar-a-Lago estate in Florida may escape Irma’s wrath, but with the deaths of so many Americans, and billions of dollars in damage to homes and businesses, the costs of climate change denial are beginning to pile up at the door of the White House.

Just days before Harvey formed in the Atlantic last month, Trump signed an executive order to overturn a policy, introduced by his predecessor Barack Obama, to help American communities and businesses become more resilient against the risks of flooding, which are rising because of climate change.

But the merciless assault on the US mainland by Harvey and Irma should be forcing the president to recognise the consequences of his arrogance and complacency in dismissing the research and analysis carried out by scientists.

The flooded streets of Houston and the wind-ravaged homes of south Florida bear the unmistakable fingerprint of extreme weather made worse by manmade greenhouse gas emissions.

President Trump’s War on Science

The news was hard to digest until one realized it was part of a much larger and increasingly disturbing pattern in the Trump administration. On Aug. 18, the National Academies of Sciences, Engineering and Medicine received an order from the Interior Department that it stop work on what seemed a useful and overdue study of the health risks of mountaintop-removal coal mining.

The $1 million study had been requested by two West Virginia health agencies following multiple studies suggesting increased rates of birth defects, cancer and other health problems among people living near big surface coal-mining operations in Appalachia. The order to shut it down came just hours before the scientists were scheduled to meet with affected residents of Kentucky.

The Interior Department said the project was put on hold as a result of an agencywide budgetary review of grants and projects costing more than $100,000.

Hurricanes and Climate Change: What We Know

Climate change intersects with hurricanes by increasing storm rainfall, intensity, and surge.

A warming atmosphere causes more evaporation, meaning more water is available for precipitation. For every 1°F increase in temperature, the atmosphere can hold around 4 percent more water vapor, which leads to heavier rain and increases the risk of flooding of rivers and streams. We saw the impact of extreme rainfall during Harvey. Though no research has yet been done to attribute the staggering rainfall totals from this storm to climate change, the downpours are very much in line with heavy precipitation trends.

Warm water provides the fuel for hurricanes. Climate change has heated up ocean waters around the world by 1-3°F over the past century, including in regions where hurricanes develop. That allows hurricanes to grow stronger, potentially increasing their maximum wind speed. One study indicates that hurricanes are intensifying more quickly than 30 years ago. Of course, there are other factors that can limit how powerful a hurricane becomes, such as how the wind changes directions and speed upward through the atmosphere.

Warming oceans and melting land ice have also caused about seven inches of global sea level rise over the past century. This gives storm surge —the coastal flooding that hits suddenly before landfall — a springboard to send floodwaters higher and push further inland than they used to. That in turn can cause more damage to infrastructure and puts additional lives at risk.

There has already been an increase in frequency and intensity of the strongest hurricanes in the Atlantic since the satellite era began. Looking forward, hurricanes are projected to produce more rain. The strongest storms are also expected to become more common. However, the overall frequency of hurricanes is projected to be nearly the same, or perhaps even decrease.

SkS in the News...

In his Miami Herald opinion piece, President Trump, hurricanes Harvey and Irma are sending you a message, Andres Oppenheimer states...

But 97 percent of climate scientists agree that global warming is being caused by man-made toxic gases, according to a 2013 scientific paper that examined 11,944 climate abstracts. That paper drives climate skeptics mad, but virtually all studies show that there is a near total consensus around man-made climate change among scientists, and that climate deniers are in most cases pseudo-scientists or conservative radio charlatans.

A. Siegel begins his blog* post article, For @NASA, @RealDonaldTrump proposes #climate #science denier with...

In another Friday dump, Team Trump’s choice for NASA:Representative Rep. Jim Bridenstine (R-OK), a true climate zombie. Here is material from his statement that called on President Obama to cut climate science funding to move it to weather research. global temperatures stopped rising 10 years ago. False. This is such classic twisted denial that Skeptical Science created the “escalator” gif to provide context. Okay, I’m lazy. I’ll stick with Skeptical Science and climate science denial by the numbers.

Climate Change Explained

Climate Change Explained. The Daily Conversation Dec 2, 2015

A straightforward explanation of Climate Change: the heat from human emissions is roughly equal to exploding 400,000 Hiroshima atomic bombs every day. Historically, every time carbon dioxide levels increase in Earth's atmosphere, the average surface temperature increases, ice melts, and the seas rise.
