Yep. the IPCC report is a mess. Im always happy to talk about the studies the IPCC actually used, but the IPCC is a political report, not a peer review document. I don't know why you obsess over it honestly. It's such a time wasting piece of garbage, time that could be better spent reading actual research.

You don't believe the IPCC got their data on the climate models in Table 9.5 from the modellers?

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.
Hence, you choose to argue about reports, while ignoring rising sea temperatures, air temperatures, desertification, ice coverage loss, changing rainfall patterns and changes in ocean currents. you know, all the stuff that matters.

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."

. 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.

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.

The pristine buoy data put a "cooling bias" on the perceived warm engine room data.

Please look at the CSIRO.

Climate changes. Now link it to AGW.

AGW is hitting part of Spain, causing draught and fast–rising temperatures"

800 gallons per second are pumped out the river and sent to irrigated fields,mainly rice paddies. The water is tested hourly and pumping stops if salt concentrations get too high. So the rice plants face death from too much salt in the water or from not enough water. This gets worse as this area of Spain gets hotter and drier. Less fresh water from rain coming down the river means seawater pushing further into the river every flood tide.

That isn’t all.

So aquifers are being drained to provide water to grow strawberries. That can go on only so long.

But that’s not all!

Quote:


Temperatures increasing by .7°C every decade.

This is similar but more extreme  to what is happening to Southern Australia.

Things can be done in Guadalquivir part of Spain: barriers to prevent ingress of sea water, stricter enforcement of rules re drilling of wells and pumping water from the aquifers.

That .7°C increase every decade and ever–worsening droughts will be harder to live with.

From the article linked above:

Quote:


We have seen that sea level rise from Greenland melting/calving has recently accelerated. Antarctica too is starting to add to sea level rise.

People are so scared on Kiribati the population has increased by about 20% since 2005.

7°C.

And more and more frequent droughts.

And, not mentioned in the article, rising sea levels pushing salt water further and further inland. Big storms should see flooding over larger and larger areas, destroying soils, aquifers etc.
