Is “Climate change accelerating”?

“Climate change impact accelerating: report”

“Climate change is accelerating, with carbon dioxide levels increasing, sea levels rising and ice sheets melting faster than ever, ‘experts’ have warned. The warning from the World Meteorological Organisation (WMO) forms part of a ‘united in science’ review for a UN climate action summit at which countries are being urged to increase their ambition to tackle emissions.

The WMO has published a report showing climate change and its impacts over the past five years between 2015 and 2019, which shows it was the hottest five-year period on record.

Terms like “united in science” and “countries being urged” betray the political nature of the ‘report’.

There are a number of false claims in this ‘report’ but the main one is the time period:

  • Five years is an insignificant period relative to decadal oscilattions and Climate variability effects, such as ENSO, the IOD and the PDO.
  • There is no mention of the major cause of Climate change, which is Milankovitch cycles.
  • In any cycle, regular or irregular, there are periods of short-term acceleration and also periods of short-term deceleration. Think about a sine wave.
  • The ‘on record’ claim is ludicrous in context. The temperature record was only made possible in 1714 when Fahrenheit invented the first accurate thermometer. Thermometers only became widespread in the US in the 1920s – and later in less developed countries. 100 years is the blink of an eye in Climate Change timeframes.
  • ‘Anthropogenic’ has been dropped from ‘Anthropogenic Global Warming’ which has morphed into ‘Climate Change’, so now when natural causes *still* predominate, humans get the blame.

In fact:

  • The climate has always changed
  • Humans do contribute to Climate change
  • Climate change does accelerate in parts of the cycle.

The report is sophisticated propaganda, which uses exaggeration and omission to achieve a political objective.

The WMO’s objectives are obviously political and therefore their releases should be regarded as highly ‘suss’.

The chart shows the time in context.

The five years of ‘acceleration’ is less than a pixel on an 800-pixel wide chart – and the horizontal axis is a log scale.
