Data says NO Climate Change link in Louisiana Hurricanes

Hurricane data shows neither frequency nor intensity have increased  for Louisiana since 1851.

With hurricane Laura now targeting Louisiana, there will be the predictable climate alarmist claims that this hurricane was either somehow made worse by “climate change”, or that “climate change” is making them more frequent, or both.

But, the data says otherwise. An analysis of historical data by climatologist Dr. Roy Spencer of the University of Alabama, Huntsville shows neither hurricane numbers nor intensities have increased in Louisiana.

He writes on his website:

“If we examine all of the hurricanes affecting Louisiana in the last 170 years in the National Hurricane Center’s HURDAT database (as summarized on Wikipedia) we find that there has been no long-term increase in either the number of hurricanes or their intensity since 1851.

This is based upon official NOAA National Hurricane Center (NHC) statistics.”

He graphed both frequency (top) and intensity (bottom):

Figure1: Neither the number nor intensity of hurricanes impacting Louisiana since 1851 have experienced a long-term increase, assuming major Hurricane Laura (2020) makes landfall as a Cat4 storm.

Clearly, the trend in frequency and intensity is downward, yet you can be assured the media won’t do any such analysis, preferring to stick to the “fake news” of climate narrative instead.

In fact, they are already at it:

For those interested in factual, real-world data, rather than the climate narrative, you can learn more in Dr. Spencer’s Amazon Kindle book: Inevitable Disaster: Why Hurricanes Can’t Be Blamed On Global Warming

  1. NONE of the facts matter. Normally, I try to avoid political commentary, but I feel compelled to interject. Unfortunately, through a combination of a predominantly low informed citizens and a media that overwhelmingly “enables” the climate alarmists and “Keep it in the Ground” types, there is little to NO CHANCE for any rational discussion on climate science or energy transition at this juncture. As I am sure you guys at Heartland are (already) aware, the Democratic Senate Committee on the Climate Crisis issued their 263 page “treatise” earlier this week. Very FEW media outlets will even (remotely) challenge that manifesto. I could not even imagine any type of policy prescription such as this could possibly exist even ten years ago. Unfortunately, the ROUT is on. As a retired oil & gas regulatory professional, I found it especially egregious regarding the blatant falsehoods concocted in the final section “Dark Money.” PROJECTION of long standing environmental activist funding & tactics onto the fossil fuel industry and conservative think tanks. A dubious narrative (at best), almost assuredly it will go unnoticed in the mainstream media. I really appreciate the effort that Heartland makes to bring some sense of balance to the debate. Keep up the good fight. It has to be an exhausting endeavor at this stage…
