Back in October 2009, my post “A Cherry-Picker’s Guide to Temperature Trends” examined the many different statements that could be made to describe the tendencies of global temperatures over the past 20 years. I concluded that anything from rapid cooling to a faster than expected warming could be supported by carefully picking through the available data.
Now, more than a year later, and after one of the “warmest years on record,” I’ve updated my analysis so that any new statements characterizing global temperature can be evaluated against the complete set of recent observations.
In general, I find that statements such as “global warming has stopped” should be tempered, at least for the time being. But I conclude that my original article’s summary remains more or less* applicable:

On Wednesday morning, The Electric Reliability Council of Texas (ERCOT), operating the power grid for much of the state, called upon local distribution companies to cut power to blocks of consumers on a rotating basis.
The rolling outages produced hardship for millions, and even isolated instances of severe harm. Consumers and policymakers are dissecting what went wrong and what should be done about it. The following is a preliminary analysis based on public data and news reports. A subsequent post will present more details once more complete information becomes available.
In brief, extreme cold weather pushed power demand to very high winter levels.…

President Obama proposed in the 2011 State of the Union Address (SOU) that we have a goal of 80% of our energy coming from “clean” sources by 2035. The goal was not clarified as to the definition of clean energy so it is assumed that the mix of production will include renewables, e.g. wind, solar, geothermal, biomass, etc. as defined by the U.S. Energy Information Agency (EIA), nuclear, and others such as clean coal.
So what are we really talking about in such a major energy transformation? …
