I believe that you would be more comfortable arguing minutia on a complex political report than giving a explanation for why the earth is warming at least ten times faster than any previous period in earth history(at least since it established a biosphere), that doesnt include a large AGW component.
Well first that would have to be established. Did you read Marcott's Explanation?
"Global Temperature Reconstruction: We combined published proxy temperature records from across the globe to develop regional and global temperature reconstructions spanning the past ~11,300 years with a resolution >300 yr; previous reconstructions of global and hemispheric temperatures primarily spanned the last one to two thousand years."
you lose a lot of data in 300 years.
. At present you are talking 130 years. Longer timespans lose more data.
"Holocene Temperature Distribution: Based on comparison of the instrumental record of global temperature change with the distribution of Holocene global average temperatures from our paleo-reconstruction, we find that the decade 2000-2009 has probably not exceeded the warmest temperatures of the early Holocene, but is warmer than ~75% of all temperatures during the Holocene. In contrast, the decade 1900-1909 was cooler than~95% of the Holocene. Therefore, we conclude that global temperature has risen from near the coldest to the warmest levels of the Holocene in the past century. Further, we compare the Holocene paleotemperature distribution with published temperature projections for 2100 CE, and find that these projections exceed the range of Holocene global average temperatures under all plausible emissions scenarios. "
The biosphere existed before humans.
"Q: What do paleotemperature reconstructions show about the temperature of the last 100 years?
A: Our global paleotemperature reconstruction includes a so-called “uptick” in temperatures during the 20th-century. However, in the paper we make the point that this particular feature is of shorter duration than the inherent smoothing in our statistical averaging procedure, and that it is based on only a few available paleo-reconstructions of the type we used. Thus, the 20th century portion of our paleotemperature stack is not statistically robust, cannot be considered representative of global temperature changes, and therefore is not the basis of any of our conclusions.

Hence, you choose to argue about reports, while ignoring rising sea temperatures
Oh dear, back to sea surface temperatures. Taken as given back to 1880. Ships buckets were used to take the temperature. Then they were taken in ships engine rooms, at various depths, depending on whether the ship was laden or not. And the ship's engine rooms warm the water. See Hausfather's reconstruction.

desertification,
Please look at the CSIRO.

changing rainfall patterns and changes in ocean currents. you know, all the stuff that matters.
Climate changes. Now link it to AGW.
