Oh look, 0.86 degree temperature rise since 1983 - pretty much bang in the middle of those predictions.
So tell me how they arrive at the global temperature? perhaps I can help you there. This is a little older but explains a lot. -
"The Japanese Meteorological Agency released data on January 5, 2015, that showed 2014 was the warmest year on its record. NASA and NOAA made a similar announcement on January 16. The UK Met Office, which maintains the fourth major global temperature record, ranked 2014 as tied with 2010 for being the hottest year on record on January 26."
"The four research groups mentioned above deal with those gaps in slightly different ways. The Japanese group leaves areas without plenty of temperature stations out of their analysis, so its analysis covers about
85 percent of the globe. The Met Office makes similar choices, meaning its record covers about
86 percent of Earth’s surface. NOAA takes a different approach to the gaps,
using nearby stations to interpolate temperatures in some areas that lack stations, giving the NOAA analysis
93 percent coverage of the globe. The group at NASA interpolates even more aggressively—areas with gaps are interpolated from the nearest station up to
1,200 kilometers away—and offers 99 percent coverage."

And they can tell temperatue all rhe way back to 1880 to within 1/100 of a degree.

I suggest you look at NOAA's Climate at a Glance.
1983 the anomaly was 0.43ºC and 2021 is 0.85ºC. that makes the warming 0.42ºC. About twice what you mention. Why is that?
https://www.ncdc.noaa.gov/cag/global/time-seriesSet Start date to March 1983 and the end date to 2021.

Why are climate "skeptics" always blatant liars?
Why do you try to discredit yourself? You are succeeding.
