Fake Media Blaming Heatwave On Climate Change

Written by H Sterling Burnett on August 22, 2020. Posted in Current News

Dozens of prominent media outlets have published stories in the last few days claiming climate change is causing wildfires and a deadly heatwave. Objective data, however, show there has been no increase in either one as the Earth modestly warms.

A story on the Colorado Public Radio website, titled “Colorado Wildfires Are Climate Change ‘In The Here And Now’ — And A Sign Of Summers To Come,” explicitly links wildfires in the state to human-caused climate change, warning of worse to come.

The Washington Post (“Why California Wildfires are So Extreme Right Now,”) and Capitol Public Radio News (CPRN), “As Californians Deal With Heat, Lightning, Fire, Scientists Point To Climate Change,” also claim a heatwave and wildfires in California right now are caused by climate change.

“The heatwave, the fires and weather patterns are in part related to climate change, says UCLA climate scientist Daniel Swain, because warming temperatures are ‘with great certainty’ increasing these conditions,” CPRN’s reporter writes.

“This whole event started as a record-breaking heatwave … and we also know that climate change is increasing the severity and the acres burned by wildfires in California,” Swain told CPRN.

The CPRN reporter doesn’t question Swain’s asserted link between climate change and wildfires, despite the fact he provides no evidence to back it up. In fact, no such evidence exists.

Data show the number and severity of heatwaves, droughts, and wildfires have all decreased over the past century and a half, even as the planet has modestly warmed.

As summarized in Climate at a Glance: Heatwaves, data from the U.S. Climate Reference Network and the National Oceanic and Atmospheric Administration prove climate change has not increased the number or severity of heatwaves.

Indeed, in recent decades heatwaves have been far less frequent and severe, for example, than in the 1930s – nearly 100 years of global warming ago.

In fact, 40 states’ record-high temperatures were set before 1960, with 25 of the record highs being set or tied in the 1930s alone.

The most accurate nationwide temperature station network, implemented in 2005, shows no sustained increase in daily high temperatures in the United States since at least 2005.

Concerning droughts and wildfires, the data is just as clear – there has been a downward trend during the past century.

Data from the National Integrated Drought Information System (NIDIS) cited in Climate at a Glance: Drought shows droughts have not become more frequent or severe in recent years.

In point of fact, the evidence shows the United States is undergoing its longest period in recorded history without at least 40 percent of the country experiencing “very dry” conditions.

Indeed, in 2017 and 2019, the United States registered its smallest percentage of land area experiencing drought in recorded history.

And the U.N. Intergovernmental Panel on Climate Change (IPCC) reports with “high confidence” precipitation over mid-latitude land areas of the Northern Hemisphere (including the United States) has increased during the past 70 years, while IPCC has “low confidence” about any negative trends globally.

Regarding wildfires, since drought is the key contributing climate factor, one should not be surprised to find, as reported in Climate at a Glance: Wildfires, records from the U.S. National Interagency Fire Center (NIFC) show wildfires have declined in number and severity in recent decades.

The NIFC tracks data on U.S. wildfires back as far as 1926, and it shows the number of acres burned is far less now than it was throughout the early 20th century.

As the Figure below shows, current acres burned run about 1/4th to 1/5th of the record values which occurred in the 1930s.

Globally, the data on wildfires is just as clear. On page 67 of Bjorn Lomborg’s book False Alarm, he points to research demonstrating:

“There is plenty of evidence for a reduction in the level of devastation caused by fire, with satellites showing a 25 percent reduction globally in burned areas just over the past 18 years … In total, the global amount of area burned as declined by more than 540,000 square miles, from 1.9 million square miles in the early part of the last century to 1.4 million square miles today.”

While the economic costs of wildfires have increased in recent decades, that is due to ever greater numbers of people moving into, and communities expanding into, areas historically prone to wildfires.

Also, people are erecting ever more expensive homes, commercial developments, and related infrastructure there. Urban development in formerly rural, wildfire-prone areas is the reason economic costs from wildfires are increasing.

Scientists can say what they want and journalists can write what they want about climate change, but, if they say climate change is causing an increase in the number or severity of heatwaves, drought, and wildfires, they are lying. The data prove it.
