Solar Activity and Climate Change

Courtillot, 2021 presents compelling evidence that planetary dynamics can materially influence the solar radiance. The sharpened decline of solar activity since 1990 is evident in sun spot data: Finding whether the planets of the solar system, and in particular the Jovian planets, have an influence on planet Earth is currently undergoing a revival and hasContinue reading “Solar Activity and Climate Change”

Variability as Climate Change Driver

Per Roy Spencer: Significantly, extrapolating to zero population density would give essentially no warming in the United States during 1973-2011. As we shall see (below) official temperature datasets say this period had a substantial warming trend, consistent with the warming in the highest population density locations. How can one explain this result other than, atContinue reading “Variability as Climate Change Driver”

No Evidence of Anthropogenic GHG Emission Reduction Impacting Atmospheric GHG Concentration

Dr. Roy Spencer: The U.S. Energy Information Agency (EIA) estimates that the economic downturn in 2020 produced only an 11% reduction in fossil fuel use. The resulting change in atmospheric CO2 concentration was unmeasurable. Furthermore, while we nibble around the edges of the “carbon pollution” problem, China’s CO2 emissions continue to grow. htpp:///www.drroyspencer.com/2021/01/biden-to-end-fossil-fuel-subsidies-like-the-paris-agreement-it-will-make-no-difference/

Cooler Canada

The anthropogenic hypothesis holds the rising concentration of greenhouse gases is due to human activities alone with no contribution from natural sources. Natural sources can be the result of temperature change from non-greenhouse gas drivers and from natural sources (e.g., ocean, landmass). Atmospheric GHG has been growing steadily with no material change in slope forContinue reading “Cooler Canada”

Solar Minimum and Plunging Cold

Europe has been taking it on the chin this month pushing up European power and gas prices to their highest levels in years, and record spikes in power markets. “The current cold spell in the northern hemisphere is paving way for a tighter global gas market throughout the year,” said Massimo Di Odoardo, director ofContinue reading “Solar Minimum and Plunging Cold”

Climate Change – Grand Solar Minimum Hits

Tens of millions of Americans in Mid-Atlantic and Northeast states were blanketed with more snow in one setting than the 2019-2020 season.  This isn’t just an isolated event – record snowfall and cold is increasingly evident throughout the world as the Grand Solar Minimum (GSM) takes shape ending the temperature ramp-up begun with the end ofContinue reading “Climate Change – Grand Solar Minimum Hits”

ENSO and Climate Temperature

There are a lot of ways physics can explain climate warming. But the best explanations are those that successfully backtest – where the physics can reliably hindcast the past from the present. Two issues, in particular, plague the IPCC CMIPx model series: (1) cloud formation and (2) the role of el Nino and the SouthernContinue reading “ENSO and Climate Temperature”

No Change Month-Over-Month

The linear warming trend since January, 1979 remains at +0.14 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.19 C/decade over global-averaged land). But with La Nina surface cooling ahead, minimum temperatures (and El Nino maximum temperatures) show up around February, March, or April. The tropical (20N-20S) temperature anomaly for November was +0.29 deg. C,Continue reading “No Change Month-Over-Month”
