This square represents a way cast doubt on the quality of our measurements, the extent of our proxies, and other aspects of the evidence basis supporting AGW.
Examples
All the climate scientists are faking their data for funding.

Objections and Replies
Adjustments. All data are adjusted, therefore they’re crap—
☞ Welcome to reality. Embrace crappiness or you’ll remain unhappy {1}.
All Theory. AGW is all theory and no data, and there is no middle ground—
☞ On the contrary, a theory without data is blind, and data without a theory are void. We need both data and theory to do science.
Anomalies.
Better. If only we could have a better resolution of—
☞ A pixel-by-pixel representation of the Earth with absolutely exact temps at each point of the time continuum would indeed be great. Until then what we got will have to do {2}
Buckets.
Error. If your data is corrupt or inaccurate then your result will be erroneous—
☞ According to thy Wiki, random errors “can be estimated by comparing multiple measurements, and reduced by averaging multiple measurements.” Systematic errors only affect absolute measurements. Anomalies will be fine.
Global Temperature. A single temperature for Earth isn’t poss—
☞ Only zero-dimensional sanity checks do that.
Lab. In a lab, there is no day and night, and the local humidity level—
☞ Humidity can indeed mask CO2 contribution. In the desert there is still considerable backradiation, however, as can be measured with a pyrgeometer or even a cheap IR thermometer (Vaughan Pratt).
Metrics.
☞
No. There is no data set to complete your claim—
☞ Where have you checked?
Reconstructions. The Auditor found problems with many datasets—
☞ Science marches one funeral at a time. Contrarian zombies are already dead. If you got a better recon, I’m all ears.
Satellites. Satellites are the most accurate measurements—
☞ They’re model-based as they measure brightness, not temperatures. Also, researchers may have misunderestimated warming of the lower troposphere for 40 years.
Sea level. There has not been a long-term distinctive change in sea level—
☞ There has. You’re not listening to Tony, Pierre or Kenneth, are you?
Stations.
Time Series. But this or that time series—
☞ The five main ones show significant global warming.
Troposphere.
☞
Urban Heat.

Notes
{} Crappiness. Databases are crap. Let’s embrace crappiness instead of channeling impossible demands of perfection.
