With this in mind, let us look again at the chart depicting the first 2 decades of the 21st century as a repeat of the 1960s and 1970s, but overlay a pattern of multiple sloped steps:
Note that virtually all of the warming can be attributed to less negative variance versus the early part of the century. This is consistent with loss of rural reporting stations and general urbanization, not because maximum temperatures have been increasing, and could explain some of the lack of significant negative anomalies in the last half of the 20th century.
We already have some indication of a cooling period beginning. If it does continue, perhaps the declaration of global warming requires additional evaluation.
Nature tends to avoid simple or linear processes.
