Climate Warming Doomsday Scenario: What, Me Worry? Part5

Should anyone worry about "global boiling" - the newest climate-porn phrase being used by the scientific illiterate?

There's good news: The answer is 'no'! In the real-world, there exists no factual evidence supporting the fantastical assertion that our world is boiling, which would obviously lead to a doomsday scenario.

Neither natural warming nor anthropogenic warming is creating an unstable climate that would be represented by accelerating temperature increases of greater and greater magnitude.

As these two charts of satellite climate measurements depict, global temperatures follow a change pattern of increasing/decreasing magnitudes over different time spans, similar to the pattern of accelerating and decelerating temperatures revealed by the chart accompanying the very first article of this series. 

The repeating pattern of temperature change is absolutely NOT a result of ever-increasing human CO2 emissions but instead of natural climate origins.

Visually, it is readily apparent that growing atmospheric CO2 levels are not associated with temperature changes.

To confirm that numerically, the average temperature change (i.e. black curve) has a low correlation with the increasing CO2 levels (i.e. green dots) that results in a barely positive R² of +0.002. For the bottom chart, the R² is +0.008.

Respectively, the monthly linear trend of the average temperature magnitude change for the top chart is flat-lined at a minuscule +0.00006; and for the bottom chart, it is an equally unimpressive, tiny +0.00013.

 

Literally, the long-term magnitude of these temperature changes is climatically insignificant.

What, me worry about "global boiling"? There is no need since the empirical evidence unequivocally debunks this.

Climate Warming Doomsday Scenario: What, Me Worry? Part4

The CAGW hypothesis calls for a rapid acceleration of global warming from human CO2 emissions, which is not taking place, based on the empirical evidence observed in 'Part#1' of the article series.

The hypothesis also calls for the temperature changes to become of greater magnitude due to positive feedback mechanisms initiated by the higher CO2 levels in the atmosphere.

However, that is not taking place either.

As this scatter plot reveals, over the last 30 years there is zero relationship - R² equals +0.003 - between atmospheric CO2 levels and subsequent 12-month temperature anomaly changes.

Note that the regression is negative instead of the predicted positive feedback result, which could be interpreted as CO2 increases causing smaller-magnitude temperature changes

Which leads us to the following: If the magnitude of global temperature increases is not associated with the growth of atmospheric CO2 levels from fossil fuel combustion, then claiming these emissions are causing a runaway climate warming, doomsday scenario, tipping-point is truly without serious scientific merit.

Central England Temperatures: Update of Old 2009 Temp & CO2 Chart

One of C3's old Central England Temperature (CET) charts shows up now and then on Twitter ('X') despite being quite dated. The most recent example was this tweet by @EcoSenseNow using a chart from an article we posted way back on January 13, 2010.

The fact that this chart is still being used, we thought it was time to update the chart with the new data since 2009. And we included with the updated chart the yellow box of text that was often added to 'C3' charts from 2009-2012. (The original chart included a yellow box of text.)
