Study: a ‘statistically significant downward trend since 1950 exists’ in hurricane landfalls

MORE inconvenient climate “science”…

Watts Up With That?

This is going to rattle some cages, while at the same time vindicating Dr. Roger Pielke Jr. A new study in Geophysical research Letters studies hurricane activity in the Atlantic concludes that a “statistically significant downward trend since 1950 exists”.

An Energetic Perspective on United States Tropical Cyclone Landfall Droughts
Authors Ryan E. Truchelut, Erica M. Staehling

Abstract

The extremely active 2017 Atlantic hurricane season concluded an extended period of quiescent continental United States tropical cyclone landfall activity that began in 2006, commonly referred to as the landfall drought. We introduce an extended climatology of U.S. tropical cyclone activity based on accumulated cyclone energy (ACE) and use this data set to investigate variability and trends in landfall activity. The drought years between 2006 and 2016 recorded an average value of total annual ACE over the U.S. that was less than 60% of the 1900–2017 average. Scaling this landfall activity metric by basin-wide activity…

EXTREME WEATHER Expert: “World Is Presently In An Era Of Unusually Low Weather Disasters”

EXTREME Weather data.jpg

CLIMATE sceptics have been consistently pointing to data rather than superstition, politics and emotion in order to examine the contentious relationship between human CO2 emissions and global warming climate change.

Climate alarmists will frequently default to the “extreme weather” narrative in order to deceptively promote the catastrophic anthropogenic global warming (CAGW) narrative by instilling fear, doom and gloom directly into the human psyche.

However, by most metrics, the data shows us that extreme weather events are becoming ‘less’ extreme as CO2 increases.

Climate Depot with more…

Professor Roger Pielke Jr. of the University of Colorado Boulder: “The world is presently in an era of unusually low weather disasters. This holds for the weather phenomena that have historically caused the most damage: tropical cyclones, floods, tornadoes and drought. Given how weather events have become politicized in debates over climate change, some find this hard to believe…

The US has seen a decrease of about 20% in both hurricane frequency and intensity at landfall since 1900…

Data on floods, drought and tornadoes are similar in that they show little to no indication of becoming more severe or frequent…

Thus, it is fair to conclude that the costs of disasters worldwide is depressed because, as the global economy has grown, disaster costs have not grown at the same rate. Thus, disaster costs as a proportion of GDP have decreased. One important reason for this is a lack of increase in the weather events that cause disasters, most notably, tropical cyclones worldwide and especially hurricanes in the United States.

Why has this occurred? Is it good luck, climate change or something else?

A good place to start is with tropical cyclones, given that they are often the most costly weather events to occur each year.  The figure below shows global tropical cyclone landfalls from 1990 through 2016. These are the storms that cause the overwhelming majority of property damage. Since 1990 there has been a reduction of about 3 landfalling storms per year (from ~17 to ~14), which certainly helps to explain why disaster losses are somewhat depressed.

Even more striking is the extended period in the United States, which has the most exposure to tropical cyclone damage, without the landfall of an intense hurricane. The figure below shows the number of days between each landfall of a Category 3+ hurricane in the US, starting in 1900. As of this writing the tally is approaching 4500 days, which is a streak of good fortune not seen in the historical record.

Extreme Weather Is Not Getting Worse – Dr Roger Pielke Jr

Dear climate change alarmist media, politicians and the warming faithful,

*Extreme weather is NOT getting worse*

The inconvenient data laid out here on one the favoured weapons of mass climate hysteria – “Extreme Weather”, by climate change disaster expert – Dr. Roger Pielke Jr., a Professor in the Environmental Studies Program at the University of Colorado…

“Floods suck when they occur. The good news is U.S. flood damage is sharply down over 70 years,”

In a message aimed at climate activists and many in the media, Pielke cautioned:

“Remember, disasters can happen any time and they suck. But it is also good to understand long-term trends based on data, not hype.”

Pielke also pointed to the hard scientific data that shows other types of extreme weather are *not getting worse and may in fact be improving*.

“Is U.S. drought getting worse? No,” Pielke wrote

Read on for more hard scientific data that completely contradicts warming alarmist dogma that your CO2 emissions cause “extreme weather”…

NB, the next time you view, read or hear your favoured media hyperventilating over an ‘Extreme Weather’ event, remember that there weren’t as many smart phones last century, and keep in mind the old saying “if it bleeds, it leads.”

From Climate Depot:

Dr. Roger Pielke Jr., a Professor in the Environmental Studies Program at the University of Colorado and a Fellow of the Cooperative Institute for Research in Environmental Sciences (CIRES), slammed the linkage of global warming to the recent Louisiana floods and other types of extreme weather. (See: Bill Nye: Climate change is reason for Louisiana floods)

Pielke authored the 2014 book “The Rightful Place of Science: Disasters and Climate Change.”

“Flood disasters are sharply down. U.S. floods not increasing either,” Pielke Jr. declared on August 23. Pielke rebuked New York Times columnist Paul Krugman for linking floods to climate change. Krugman blamed “climate change” for ‘a proliferation of disasters like the one in Louisiana.’

“How does Krugman get away with this?” Pielke asked while showcasing this scientific graph.

“Floods suck when they occur. The good news is U.S. flood damage…
