Extreme Weather Has Nothing To Do With Global Warming
Analysis: It’s not just droughts, but nearly all extreme weather is declining or at or near record lows
"It is not just droughts that are at or near record levels. On almost every measure of extreme weather, the data is not cooperating with the claims of the climate change campaigners. Tornadoes, floods, droughts, and hurricanes are failing to fit in with the global warming narrative."
But it is not just droughts that are at or near record levels. On almost every measure of extreme weather, the data is not cooperating with the claims of the climate change campaigners. Tornadoes, floods, droughts, and hurricanes are failing to fit in with the global warming narrative.
Extreme weather used to be blamed on ‘global cooling’ in the 1970s and early 80sFlashback NOAA 1974: ‘Extreme weather events blamed on global cooling’ – NOAA October 1974: ‘Many climatologists have associated this drought and other recent weather anomalies with a global cooling trend and changes in atmospheric circulation which, if prolonged, pose serious threats to major food-producing regions of the world’
Climatologist Dr. Roy Spencer in 2016: “Global warming and climate change, even if it is 100% caused by humans, is so slow that it cannot be observed by anyone in their lifetime. Hurricanes, tornadoes, floods, droughts and other natural disasters have yet to show any obvious long-term change. This means that in order for politicians to advance policy goals (such as forcing expensive solar energy on the masses or creating a carbon tax), they have to turn normal weather disasters into “evidence” of climate change.”
New 2015 paper finds global warming reduces intense storms & extreme weather – A paper published in Science contradicts the prior belief that global warming, if it resumes, will fuel more intense storms, finding instead that an increase in water vapor and strengthened hydrological cycle will reduce the atmosphere’s ability to perform thermodynamic Work, thus decreasing the formation of intense winds, storms, and hurricanes.
“Globally, weather-related losses ($) have not increased since 1990 as a proportion of GDP (they have actually decreased by about 25%) and insured catastrophe losses have not increased as a proportion of GDP since 1960.”
Even the recent California’s drought is not related to climate change. Much more severe California droughts occurred with lower allegedly ‘safe’ CO2 levels. According to the data, “past dry periods have lasted more than 200 years.” “Researchers have documented multiple droughts in California that lasted 10 or 20 years in a row during the past 1,000 years – compared to the mere 3-year duration of the current dry spell. The two most severe mega-droughts make the Dust Bowl of the 1930s look tame: a 240-year-long drought that started in 850 and, 50 years after the conclusion of that one, another that stretched at least 180 years.”
“Floods suck when they occur. The good news is U.S. flood damage is sharply down over 70 years,” Pielke explained.
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 Jr.: But doesn’t more extreme precipitation mean more floods? Again the SREX authors in 5..4..3: ‘Despite the diagnosed extreme-precipitation-based signal, and its possible link to changes in flood patterns, no gauge-based evidence has been found for a climate-driven, globally widespread change in the magnitude and frequency of floods during the last decades.’
Pielke Jr. : ‘How about IPCC SREX authors on floods? 5..4..3..: ‘A direct statistical link between anthropogenic climate change and trends in the magnitude/frequency of floods has not been established”
“Floods have not increased in the US in frequency or intensity since at least 1950. Flood losses as a percentage of US GDP have dropped by about 75% since 1940”
Dr. Robert Holmes, USGS National Flood Hazard Coordinator: ‘The data shows no systematic increases in flooding through time’ – ‘USGS research has shown no linkage between flooding (either increases or decreases) and the increase in greenhouse gases. Essentially, from USGS long-term streamgage data for sites across the country with no regulation or other changes to the watershed that could influence the streamflow, the data shows no systematic increases in flooding through time.’
1000 year flood? ‘The majority of USGS streamgages had flood peaks that were less than 10-year floods.’ – ‘Analysis show NO indication that a 1000-year flood discharge occurred at any USGS streamgages’
Pielke Sr.: ‘From under reviewed paper to NOAA PR to USA Today. A dismaying example of manipulation of science for political reasons.’
Climate Depot’s Marc Morano on new NOAA study: “No matter how hard federally funded climate activist scientists at NOAA try to bend and twist models and data to make it appear the invisible hand of ‘global warming’ has a role in almost every weather event, the facts refute their claims.”
But Climate Depot publisher Marc Morano pointed out that those who predicted more major hurricane activity due to climate change now want to change the definition of a major hurricane because their predictions have fallen short of reality. “With a new metric, warmists can declare every storm ‘unprecedented’ and a new ‘record’,” Morano said.
Tuesday marks a record 127 months since a major hurricane has made landfall in the continental United States, according to statistics compiled by the National Oceanic and Atmospheric Administration’s (NOAA) Hurricane Research Division, which keeps data on all the hurricanes that have struck the U.S. since 1851.
The current drought in major hurricane activity is a “rare event” that occurs only once every 177 years, according to a study published last year by researchers at the NASA Goddard Institute for Space Studies (GISS) entitled The Frequency and Duration of U.S. Hurricane Droughts.
Obama has seen just four hurricanes make landfall on his watch, none of them classified by NOAA as major storms. Three were Category 1 storms (Irene in 2011; Isaac and Sandy in 2012) and just one was a Category 2 hurricane (Arthur in 2014).
