"Estimated anthropogenic (note: that means caused by humans) global warming is currently increasing at 0.2°C (likely between 0.1°C and 0.3°C) per decade due to past and ongoing emissions (high confidence)," it says in a report issued in 2021 (click to download).
This is a remarkable claim yet according to the same report (in fact on the same page) "observed global mean surface temperature (GMST) for the decade 2006-2015 was 0.87°C (likely between 0.75°C and 0.99°C) higher than the average over the 1850-1900 period (very high confidence). "
One might ask why such a well funded body as the IPCC has to rely on out of date data (2015, jeez!) but, of course, this was probably the best decade to pick if you wanted to illustrate changing climate. This is not the way science is done, but these people are on a mission to save the planet!
Climate change of 0.87°C is a very interesting figure because it is not too dissimilar to the numbers circulating in 1988 when IPCC produced its first apocalyptic report.
The inconvenient truth is that despite five IPCC reports since 1988, each saying that the situation is getting much worse than they expected, world temperatures are still roughly one degree higher than they were in pre-industrial times.
Yet according to the Mauna Loa station (the standard source for CO2 readings) CO2 levels keep rocketing up, by an incredible ten parts per million just between September 2019 and the latest figure in July 2021 (that's about 2%) (408.55 to 418.94 parts per million).
Left: IPCC projections: from top to bottom CO2 emissions, temperatures and rainfall, all in lock step. Yet CO2 emissions have rocketed up since 1988, while temperatures have stayed stubbornly stable.
