Overconfidence in IPCC’s detection and attribution. Part II | Climate Etc.

Given that the IPCC argues that multidecadal natural internal variability is not an important factor and that external forcing can explain the 20th century variability, confidence in the attribution for the latter half of the 20th century is diminished by the lack of a robust attribution for the earlier warming between 1910-1940 (which is of the same magnitude as the warming from 1970-2000) and the mid century cooling.

C3: A Scottish Loch's Evidence Substantiates Two Significant Medieval Warming Intervals, Study Shows

Numerous temperature reconstructions indicate that during the Medieval centuries, two distinct warming intervals happened. New research from a Scottish loch's sediment core analysis identified the two separate, extended warming periods between 900 and 1600AD.

Solar Cheaper than Grid Nuclear? Think Again! — MasterResource

But nuclear power is less, not more, expensive than solar power. It is also reliable, or in industry terms, dispatchable, which adds value that is not reflected in simple cost comparisons.

American Thinker: Climatism: That Climate Change Chameleon

The latest initiative from the climate change chameleon is to frame global warming as detrimental to the health of U.S. citizens. On September 28, a joint letter from 120 of America's health organizations was delivered to President Obama, supporting efforts by the Environmental Regulatory Agency to regulate greenhouse gases. The letter claims that man-made global warming is now a U.S. public health issue especially for "older adults." Yet senior citizens continue to retire to Florida, Texas, and Arizona rather than North Dakota and Minnesota. Don't they know that warmer temperatures are a serious health risk?
