Thoughts on satellite temperature measurement

Here.

Excerpt:

Any convergence of surface temperature measurements with satellite should be a source of skepticism, not confidence. We know that the surface temperature measurement system is immensely flawed: there are still many station quality issues in the US like urban biases that go uncorrected, and the rest of the world is even worse. There are also huge coverage gaps (read: oceans). The fact this system correlates with satellite measurement feels like the situation where climate models, many of which take different approaches, some of them demonstrably wrong or contradictory, all correlate well with history. It makes us suspicious the correlation is a managed artifact, not a real outcome.
