Impacts of heat, cold,
and temperature variability
on mortality in Australia,
2000-2009.
Science of the Total Environment 651:
2558-2565.
NOTE:
The U.S. Environmental
Protection Agency's (EPA)
Endangerment Finding,
issued under Barack Obama,
incorrectly called CO2,
the staff of life on our planet,
a dangerous air pollutant.
The Trump Administration
hasn't changed the EPA finding.
The alleged concern was that
rising CO2 was causing increases
in heat-related deaths.
A new study, Cheng et al. (2019),
analyzed the mortality impacts
of hot weather, cold weather,
and temperature variability
in Australia, from 2000-2009.
SUMMARY:
The U.S. EPA claim
that CO2 is a dangerous
threat to human health
is not true for Australia.
And many other studies,
conducted for locations
all across the globe,
have also falsified
the hypothesis
for the entire planet.
Attributable deaths
due to cold weather
are six times the
percentage of those
due to warm weather !
708,751 deaths studied
42,414 deaths due to weather
61.4% cold weather
28% temperature variability
10.6% hot weather
The authors said:
"most of the attributable deaths
were from cold (61.4%), and then
from temperature variability (28%)
and heat (10.6%),"
although there were noted
differences between cities.
There was no trend
in mortality related to
atmospheric CO2
concentrations
rising by 5%
over the period.
Human mortality from
cold weather events
is far more deadly
than from hot weather.
So any warming
of the planet
in the future
should have
a net positive
impact on
human mortality.
DETAILS:
The six researchers
used all-cause death
and weather data for
the five most populous
Australian cities
( Sydney, Melbourne,
Brisbane, Adelaide, Perth )
for the period from
2000 through 2009.
Those cities account for
over 60% of the total
Australian population.
Statistical analyses
allowed scientists
to calculate the
percentage of deaths
caused by cold, heat and
temperature variability.

Attributable percentage
of deaths due to cold,
due to heat, and due to
temperature variability (TV),
for five Australian cities,
and a weighted average
of the five cities.
