Environment Canada ignores temperature measurements before 1949, which included many local heat records

Blacklock’s Reporter,
“the only reporter-owned 
and operated newsroom 
in Ottawa” , focuses on 
reporting Canadian 
government documents.

About 100 years of measured 
temperatures, from 1850 to 1949,
were scrapped by Environment 
Canada when creating its computer 
models to estimate future
climate change.

Ignoring a century of observed 
weather data from 1850 to 1949,
was necessary, a spokesman for 
Environment Canada told 
Blacklock’s Reporter.

Because EC researchers 
concluded there weren’t 
enough weather stations 
to create a reliable data set 
for that 100-year period.

“The historical data 
(that we use today)
is not observed (real)
historical data,” 
the spokesman said. 
“It is modeled historical data
 … 24 models from historical 
simulations spanning 
1950 to 2005 were used.”

Computer simulations 
are used for the 
federal government’s 
ClimateData.ca 
website, for the 
pre-1949 period !



The omitted data 
had included some 
old "warmest ever"
temperature records:

-- Vancouver had 
a higher record 
temperature 
in 1910 (30.6C), 
than in 2017 (29.5C).

-- Toronto had 
a warmer summer 
in 1852 (32.2C), 
than in 2017 (31.7C).

-- The highest temperature 
in Moncton in 2017, 
was four degrees cooler 
than in 1906.

-- Brandon, Man., 
had 49 days where the 
average daily temperature 
was above 20C in 1936, 
compared to only 
16 days in 2017, 
with a high temperature 
of 43.3C that year, 
compared to 34.3C in 2017.


Politicians give the public 
inaccurate information 
about climate change 
all the time.
