Most of the electricity generated in the U.S. continues to come from fossil fuels (61% in 2021). This is not likely to change much in the future as electricity demand is increasing faster than renewables (20% of total in 2020 and 20.1% of total in 2021) can close the gap versus fossil fuels. Given that fact, it is interesting to ask the question:Which uses fossil fuels more efficiently, an EV or ICE (internal combustion engine) vehicle?Most of what you will read about EVs versus ICE … [Read more...]
Analysis of Gas Prices
Gas prices: If you look at inflation-adjusted gasoline prices over the last century, there has been an overall downward trend, reflecting greater efficiency at finding, pumping, and refining petroleum. We are now at $5 a gallon, but that isn't a whole lot more than we've been in the past (for example, just before the 2012 recession). Still, the price is a lot higher than it needs to be given current technology, and the current spike could have been mostly avoided (COVID impacts being the least … [Read more...]
Are High Energy Prices a “Bug” in the Biden Administration?
High gasoline prices are not a "bug" in the view of the Biden Administration, but a "feature." Environmentalists with enough money to pay the premium are giddy because high prices make expensive wind and solar energy more competitive. So, forget about the days when the most cost-saving ideas win in the marketplace, we are now in the era when government policies and regulations determine market prices. Hmmm ... sounds like the old U.S.S.R., eh? How did that work out? It remains to be seen if … [Read more...]
More Snow Hits the Fan this Week: Climate Change Alarmists Still Want it Both Ways
As I predicted, climate change has been blamed for the recent New England blizzard (e.g. from Bloomberg here). During that storm, Boston tied its 24-hr snowfall record at 23.6 inches.Yet, as recently as January 6, we were told by USAToday that Boston’s lengthy 316-day streak *without* one inch of snowfall as of January 1st was caused by global warming.So, which is it? Does global warming cause less snow or more snow?When science produces contradictory claims, is it really … [Read more...]
UAH Global Temperature Update for January 2022: +0.03 deg. C.
The Version 6.0 global average lower tropospheric temperature (LT) anomaly for January 2022 was +0.03 deg. C, down from the December 2021 value of +0.21 deg. C.The linear warming trend since January 1979 now stands at +0.13 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).Various regional LT departures from the 30-year (1991-2020) average for the last 13 months are:YEAR MO GLOBE NHEM.

Cornwall Alliance Scholar Demonetized by Google
DrRoySpencer.com has been demonetized by Google for “unreliable and harmful claims.” This means I can no longer generate revenue to support the website using the Google Adsense program.From a monetary standpoint, it’s not a big deal because what I make off of Google ads is in the noise level of my family’s monthly budget. It barely made more than I pay in hosting fees and an (increasingly expensive) comment spam screener.I’ve been getting Google warnings for a couple of months now about “policy … [Read more...]
Tornado Outbreak: Weather, Not Climate
This image shows today's [December 15, 2021] temperature departures from the 30-year average, which range from 30 deg. F above to 30 deg. below normal. The large unusually warm area in the U.S. Midwest is sandwiched between unusually cold air masses. Over the entire area shown it can be seen that the warm and cold spots approximately cancel out. Global warming is a quasi-global phenomenon, it cannot be blamed for temporary and isolated warm weather events. … [Read more...]
UAH Global Temperature Update for November 2021: Spoiler Alert, No Reason to Worry
The Version 6.0 global average lower tropospheric temperature (LT) anomaly for November 2021 was +0.08 deg. C, down substantially from the October 2021 value of +0.37 deg.

UAH Global Temperature Update for June 2021: -0.01 deg. C
The Version 6.0 global average lower tropospheric temperature (LT) anomaly for June, 2021 was -0.01 deg. C, down from the May, 2021 value of +0.08 deg. C.REMINDER: We have changed the 30-year averaging period from which we compute anomalies to 1991-2020, from the old period 1981-2010. This change does not affect the temperature trends.The linear warming trend since January, 1979 remains at +0.14 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged … [Read more...]
Faith In Human-Caused Global Warming
During my 30+ year career in climate change research I have come to realize the popular perception of global warming involves at least as much faith as it does science. Participation in the fight against climate change (or pollution, or COVID-19, or many other present-day problems) gives people a sense of purpose in their search for significance, even if their rituals have virtually no impact.In the case of global warming, the global energy imbalance associated with warming in recent decades is … [Read more...]
