REBUTTAL to Doctor Merritt: ‘Climate Change’ Does Not Affect Human Health, Weather Does

This story on WUWT last week was so absurd, I felt like it needed a strong rebuttal.

A November 4th article in the Canadian newspaper, Victoria Times Colonist, reported, B.C. doctor clinically diagnoses patient as suffering from ‘climate change’

On the face of it, one doesn’t need to be a climate scientist to know this is an absurd claim, because the doctor is simply making the mistake of conflating short-term weather events with long-term climate change.

Obviously, Doctor Merritt hasn’t learned what the definition of climate is. The National Oceanic and Atmospheric Administration (NOAA) clearly defines it:

Weather reflects short-term conditions of the atmosphere while climate is the average daily weather for an extended period of time at a certain location. … Weather can change from minute-to-minute, hour-to-hour, day-to-day, and season-to-season.

In the case of Dr. Merritt, he is citing a record heat wave and wildfires as creating health problems for his patients.

From the article:

“It was late June, and British Columbia was consumed under a heat wave that would soon go down as both the hottest and deadliest in Canadian history.

The head of the hospital’s emergency department, Merritt could see the aggravated toll the extreme heat took on patients battling multiple health problems at once, often with little money.”

Like death by heat, doctors have traditionally struggled to clinically attribute mortality and severe illness to air pollution. For Merritt, this summer’s wildfire season changed all that. 

When a patient came in struggling to breathe, Merritt knew the smoke — that hadn’t lifted from the region for days on end — had made a case of asthma worse. 

For the first time in his 10 years as a physician, the ER doctor picked up his patient’s chart and penned in the words “climate change.” 

“If we’re not looking at the underlying cause, and we’re just treating the symptoms, we’re just gonna keep falling further and further behind,” he told Glacier Media when asked why he did it.

While I certainly have compassion for the people afflicted, the bottom line is that these health issues are short-term events driven by weather, not climate.

The record heat wave was clearly a weather event, lasting about 3 days as the high pressure dome moved from west to east over the Pacific Northwest, and was driven by a unique set of meteorological conditions. Cliff Mass, Ph.D, an expert on meteorology at the University of Washington studied the heat wave event extensively in his article Was Global Warming The Cause of the Great Northwest Heatwave? Science Says No.

As a result of his study, Dr. Mass found no trend consistent with “climate change” aka “global warming” and came to this conclusion:

If global warming was producing extreme heatwaves in our region, such as the event last week, there would be a long-term trend towards more extreme high temperatures.  A single event does not reflect climate, only a trend or changes in long-term average do.

Mass went on to examine the long-term temperature data and adds, “…there IS NO INCREASING TREND for more record high temperatures over our region during the past century. “

That rules out Dr. Merritt’s claim of “climate change” driving health issues he witnessed, which was little more than conjecture, with no science applied at all. His diagnosis seems more like “political popular science”, as opposed to real science citing data and linking causation.

On the issues of wildfire smoke and health, Dr. Merritt disproves his own claims about a linkage with climate change with his statement to the newspaper:

“This past summer, it was so bad for about three weeks,” says Merritt. 

Again, three weeks is a short-term event, not a long-term climate trend. The main flaw in Dr. Merritt’s claim is that he erroneously conflates weather with climate. The classical period is 30 years, as defined by the World Meteorological Organization (WMO). A heat wave and the resultant fires is a short-term weather phenomenon. And, as Dr. mass points out, it would only become an indicator of climate change if it persisted for 30 years and showed an increased trend.

The wildfires were a temporary phenomenon, likely related to the short-term heat wave. NASA satellites have documented a global long-term decline in wildfires. NASA reports satellites have measured a 25-percent decrease in global lands burned since 2003.

Neither the temperature data or the wildfire data show an upward trend, rendering Merritt’s opinion of a climate change connection as flat wrong.

Dr. Merritt should stick to treating patients, and leave meteorology and climatology to experts trained in those sciences. After all, you certainly don’t see meteorologists and climatologists posing as medical professionals.

Idiot wokism is the new religion of the left – they think that just repeating some really imbecilic statement makes it true.
Yes, it was hot for a few weeks in June on the left coast – but hot weather is easy to live with – just drink lots of water.
I’ve been to southern Egypt in July, when temperatures reached 50C, and the locals survive without air conditioning and some even do light work in the middle of the day.
Those who died in BC were probably dehydrated – either the very elderly and infirm who were neglected or others who were negligent.

No, the “doctor” will look up which code will give him and the hospital the most remuneration and mark it as such. It’s all about the money in many places.

In the US, there is a 20% reward for giving a patient in hospital remdemisvir, which is known to destroy kidneys and liver. Why would they reward that unless there was an ulterior motive, such as money (or pop.decrease)?

True. Current CO2 levels in the atmosphere are about 415ppm. In a submarine, the CO2 levels can go up to about 8,000ppm, if memory serves, without detrimental effects on the crew.

So, yes CO2 can be toxic, but it takes a lot of it. A lot more than humans can put in the atmosphere.

A sensible person will drink plenty of fluids when it is very hot and not go doing strenuous exercises and find the coolest spot if there is no air conditioning. It can be quite a few degrees lower under a leafy tree than out in the sun and of course sitting in a car is like sitting in an oven. People who live in hot deserts know how to cope with the heat but tourists from cold places can be foolish.

At the start of the Pacific NW “Thermagedon” I was sitting in a car – my Chrysler T&C specifically with the air conditioning on while driving to the Oregon Coast!! It was quite pleasant as I crossed over the Columbia River bridge at Longview WA – which was crowded as I’ve ever seen it X3. We all escaped and turned west toward the coast – to enjoy cooler air. Stopped in for a late lunch in Tillamook and enjoyed a great meal from a propane powered mobile kitchen by the side of US hwy 101. I visited my friend in Coos Bay area where it was 68 degrees on a beautiful sunny, breezy day. It was 105/107 degree highs during that weekend where I live.

It sets in whenever an issue becomes political. Look at the ‘pandemic’. Then, once you get someone who can make money out of it, it becomes crony-driven. Look at renewable subsidies and vaccines (they are lobbying, and successfully, for all children to be vaccinated, and a 3rd and 4th ‘booster’ after 6 months).

How you stop it, I don’t know. The only obvious solution is smaller government to provide only basic services and infrastructure instead of trying to micromanage all of our lives. .

Actually, writing “climate change” as the diagnosis is lazy and tells others in medicine that he is lazy and almost admitting that he does not know what the patient’s real problem is. It bespeaks ignorance.

“The wildfires were a temporary phenomenon, likely related to the short-term heat wave.”

This would only be correct if the wildfires all started around that time. They did not. BC has forest fires every year, and many of them are started by lightning strikes. Furthermore, there is still a LOT of deadwood in the forests of BC as a result of the mountain pine beetle infestation of about 20 years ago.

I expect that there will be quite a few more bad forest fire years in BC, until most of the deadwood has been consumed.

The trees that burn in BC fires are mostly green, living trees. It’s incorrect to assume or assert that only deadwood burns. It’s also incorrect to believe that when “the deadwood has been consumed” BC will no longer have “bad fire years”.

Forests are alive; they grow. Every year many tons of fuel are added via growth (photosynthesis) to each acre or hectare. The fuel accumulates. The more fuel, the more (frequent, larger, hotter, destructive) fires.

The climate may warm or cool, but fuel accumulates anyway. Fuel burns in cold climates (BC), warm climates (Brazil), and in between. Wherever trees grow, fuel accumulates, and it will burn, green or dead.

Forest fires are NOT a weather phenomenon. They are a fuel phenomenon. Blaming the weather (or climate) for fires is a cop-out that fails to address the real problem and the only efffective solution set.

BC’s forest fire crisis is due to bad management that fails to control, remove, break up, or otherwise mitigate the hazard, i.e. the ever growing fuels. One reason is that most of BC’s forests are owned or controlled by government bureaucracies filled with very stupid and lazy functionaries with political agendas. It’s no consolation that most forests worldwide suffer from the same utterly useless government braying flunky mis- or non- management.

The following paper by UBC forestry researchers explains the forest management problem. They document that, historically, low to medium intensity fires burned every 10 to 30 years. When human hubris disrupted the natural cycle (and First Nations stewardship of the forests), the fire cycle lengthened to 70-180 years, making contemporary forests dense with closed canopies that are susceptible to high severity fires.

You are absolutely correct in your point that BC’s forest fires were NOT caused or exacerbated by the Heat Wave. The Horrible Heat Wave occurred June 25-28. By July 1st 40 fires were burning in BC. By the end of September 1,585 fires had burned. Thus the worst case causal analysis would assert that 40 out 1585 were Heat Wave fires, or 2.5%.

This is an important concept that is ignored by politicians and the media everywhere today.

By definition, climate change cannot affect weather.

It’s the cart before the horse. For anyone who subscribes to the idea that there is cause and effect in the physical world we all live in, the idea is preposterous.

November 8, 2021 4:34 pm


Weather reflects short-term conditions of the atmosphere while climate is the average daily weather for an extended period of time at a certain location. … Weather can change from minute-to-minute, hour-to-hour, day-to-day, and season-to-season.”

I don’t accept this ridiculous definition. What the hell is an extended amount of time? Is it roughly as long as a piece of string?
The arbitrary ”average of thirty years” is meaningless therefore to claim the climate is changing using that definition is equally meaningless.

I had the same reaction. “Extended period” is unscientifically vague and imprecise. If we’re going to worry about changing “the climate,” shouldn’t we first collect reliable data for hundreds or thousands of years?

Here in southern Arizona it’s been a desert for 12,000 years or so. That’s not going to change. Neither will the other deserts of the world, nor the tropics, nor the Arctic and Antarctic. When the next glaciation starts, then we can talk.
