Tom Harris: Is Canada’s '2x warming' claim built on bad data?
What if the claim relies on selective data and uncertain modelling, not settled fact?

Tonight on The Gunn Show, we’re taking aim at one of the most repeated climate talking points in the country: the claim that Canada is warming at twice the global average.
Sounds dramatic. Sounds definitive. But is it true?
Joining me tonight is Tom Harris of the International Climate Science Coalition Canada, who says this headline-grabbing claim is built on shaky foundations, selective data, and assumptions the federal government has long known about.
We’ll ask the obvious question few in the media seem interested in: how do you even calculate a “global average temperature” in the first place?
The Earth doesn’t have one thermostat. It has oceans, deserts, mountains, forests, cities and polar regions, all with radically different conditions. What gets sold to the public as a precise global number is actually a statistical estimate built from scattered measurements, adjusted records, sparse northern coverage, satellite inputs, and modelled gap-filling.
That may make for clean press releases. It doesn’t make for simple certainty.
So why are politicians presenting complex estimates as settled fact? And are taxpayers being pushed into costly policy based on numbers most people never get to question?
If the science is solid, it should survive scrutiny.
If the data is flawed, Canadians deserve to know.

Lynne Osborne commented 2026-04-23 13:29:35 -0400How do we know the climate is warming? Good question, how do we know? Well someone working for or paid by Environment and Climate Change Canada (ECCC) says so. Looking at the weather data for Calgary the range of historical temperatures for March (-31 to 25C), April (-19 to +28) and July (2 to +37C). Only two months of the year have historically been proven to be frost free. In terms of growing things the mean temperature for any given day is valueless. Calgar’s high yesterday was 26.6 C and today 3 C. Now that’s are carbon fueled heat wave for sure. Wonder how much standard deviation there is around any trend numbers published by Environment Canada? We are heating at a rate of twice the world average? What is Canada’s average daily temperature if Calgary only has two frost free months? Most of Canada is North of 60. Plus or minus some mean number in a range 56 C is a useless statistic. Even in the Calgary July range of 35 C. It does keep folks employed and well paid at Environment and Climate Change Canada (ECCC) though. Flights and all expences to conferences to fire up the worry are well funded. There would be no research funding handed out to anyone if their proposal did not include “Climate Change”. Proving the title to be a hoax would be very bad for Ottawa credibility. Such research would never be published. -

Matt Abrahams commented 2026-04-22 22:30:11 -0400Temperature is not a constant; it is continuously changing. No two places have the same temperature. When it is daytime and warmer on one half of the world, it is nighttime and cooler on the other half. When it is summer and warmer on one half of the world, it is winter and cooler on the other half. So, how do you determine what the “global temperature” and the “global rate of warming” is?
