IPCC AR6 Report The Working Group I contribution to the Sixth Assessment Report (WG1 AR6) of the Intergovernmental Panel on Climate Change (IPCC) raises the question: Is the IPCC seeking to downplay the dire situation that we are in, again?  Downplaying the temperature rise from pre-industrial One of the first issues that comes up is the baseline. The IPCC uses 1850–1900 as a baseline, like it did before  (in SR1.5).  This is one out of many instances where the IPCC creates a perception that it would take many years before the 1.5°C threshold would be crossed. This 1850–1900 isn't pre-industrial. The Paris Agreement calls for pre-industrial as a base.  The IPCC image on the right shows a 1.09°C rise from 1850–1900. This isn't the rise to the year 2020, but it is the rise to the  period  from 2011 to 2020.  Instead, when taking the 2020 temperature rise and going back one century, NASA data show a 1.29°C rise from 1920, and this is a conservative ...

Above image depicts how humans could go extinct as early as 2020. The image was created with NASA LOTI 1880-Nov.2019 data, 0.78°C adjusted to reflect ocean air temperatures (as opposed to sea surface temperatures), to reflect higher polar temperature anomalies (as opposed to leaving out 'missing' data) and to reflect a 1750 baseline (as opposed to a 1951-1980 baseline), with two trends added. Blue: a long-term trend based on Jan.1880-Nov.2019 data. Red: a short-term trend, based on Jan.2009-Nov.2019 data, to illustrate El Niño/La Niña variability and how El Niño could be the catalyst to trigger huge methane releases from the Arctic Ocean. How was above image created? Let's first look at the baseline. The NASA default baseline is 1951-1980. The added trend in the image below shows early 1900s data to be well below this 1951-1980 baseline. In this analysis, a 0.28°C adjustment was therefore used to reflect this, and to reflect a 1750 baseline, a further 0.3°C was used, adding...
