The climate science world (‘settled’ division) is in shock following the
discovery in ancient ice cores that levels of carbon dioxide remained
stable as the world plunged into an ice age around 2.7 million years
ago. Levels of CO2 at around 250 parts per million (ppm) were said to be
lower than often assumed with just a 20 ppm movement recorded for the
following near three million-year period. In addition, no changes in
methane levels were seen in the entire period. Massive decreases in
temperature with occasional interglacial rises appear to have occurred
without troubling ‘greenhouse’ gas levels, and this revelation has
caused near panic in activist circles.
The assumed level three
million years ago of CO2 was around 400 ppm, a convenient mark that has
been used to explain the subsequent ice age and a drop to 250 ppm. Due
to the recently published paper, this explanation has become more
problematic and natural climate variation is correctly noted to have
occurred with the temperature changes. Alas, similar explanations are
mostly ignored in discussing today’s climate changes in the interests of
promoting the Net Zero fantasy. Some cling desperately to a dominant
CO2 role, including one of the authors of the findings published in Nature.
The co-author states that the results suggest even greater climate
sensitivity to the warming effect of CO2. In short, there is a great
deal of applying the laws of physics and chemistry to one era, but
failing to extend the same courtesy to another.The title of the paper, produced by 17 America-based scientists,
was enough to set alarm bells ringing in the ‘settled’ science, Net
Zero-obsessed community: ‘Broadly stable atmospheric CO2 and CH4 levels
over the past three million years.’ A related paper
examining ocean heat content derived from the ice core record was also
published. Carrie Lear, Professor of Past Climates and Earth System
Changes at Cardiff University, claimed that the papers “don’t rewrite
the role of CO2, they underline how sensitive the climate system is… that is why today’s rapid CO2 rise is so alarming”.
Ah,
yes. Even if CO2 movements are minimal, probably within a margin of
potential error, they are still responsible for large variations in
temperature. The laws of climate science are ‘settled’ – if the trace
atmospheric gas CO2 is rising, falling or generally stable, it is almost
wholly responsible for large movements in global temperature. Under
this rather shaky assumption, humans must stop burning hydrocarbons and
return to a neo-Malthusian pre-industrial age...<<<Read More>>>...
