A singular “clean energy” metric distorts sustainability assessment

Using a singular metric like “clean” energy distorts assessment of sustainability. By focusing on a singular metric organizations (e.g. World Economic Forum) are being seriously mislead. Achieving sustainability extends way beyond using “clean” ( and unreliable) energy. Indeed, the preoccupation with decarbonization is misdirected. Attempting to decarbonize is an unsustainable goal in and of itself.

“A recent Carbon Brief report written by E4tech and Imperial College London and published by Drax has ranked 25 major world economies on their efforts (or lack thereof) in the transition to clean energy.” click here

Solar activity drove a significant percentage of recent warming

Nicola Scafetta and Richard C. Willson. Comparison of Decadal Trends among Total Solar Irradiance Composites of Satellite Observations. Advances in Astronomy Volume 2019, https://doi.org/10.1155/2019/1214896

We present a new analysis of the two-decade-old controversy over interpretation of satellite observations of total solar irradiance (TSI) since 1978 and the implications of our findings for TSI as a driver of climate change. Our approach compares the methods of constructing the two most commonly referenced TSI composites (ACRIM and PMOD) that relate successive observational databases and two others recently constructed using a novel statistical approach. Our primary focus is on the disparate decadal trending results of the ACRIM and PMOD TSI composite time series, namely, whether they indicate an increasing trend from 1980 to 2000 and a decreasing trend thereafter (ACRIM) or a continuously decreasing trend since 1980 (PMOD). Construction of the four-decade observational TSI composites from 1978 to the present requires the use of results from two less precise Earth Radiation Budget experiments (Nimbus7/ERB and ERBS/ERBE) during the so-called ACRIM-Gap (1989.5–1991.8), between the end of the ACRIM1 and the beginning of the ACRIM2 experiments. The ACRIM and PMOD composites used the ERB and ERBE results, respectively, to bridge the gap. The well-established paradigm of positive correlation between Solar Magnetic Field Strength (SMFS) and TSI supports the validity of the upward trend in the ERB results and the corresponding decadal upward trend of the ACRIM composite during solar cycles 21 and 22. The ERBE results have a sensor degradation caused downward gap trend, contrary to the SMFS/TSI paradigm, that biased the PMOD composite decadal trend downward during solar cycles 21 and 22. The different choice of gap bridging data is clearly the cause of the ACRIM and PMOD TSI trending difference, agreeing closely in both magnitude and direction. We also analyze two recently proposed statistical TSI composites. Unfortunately their methodology cannot account for the gap degradation of the ERBE experiment and their resulting uncertainties are too large to uniquely distinguish between the trending of the ACRIM and PMOD composites. Our analysis supports the ACRIM TSI increasing trend during the 1980 to 2000 period, followed by a long-term decreasing trend since.

The polar bear crisis that never happend

“In her book Dr. Crockford explains how activist researchers tried to create a polar bear crisis using shoddy computer simulations, bad science and hiding inconvenient facts. But now their failed predictions have led to a total loss of scientific credibility, which Crockford says “they entirely deserve”. “ click here

Fact-check the AP on climate

“Borenstein, the chief climate reporter for the Associated Press, has a long history of promoting dubious climate claims and essentially lobbying the public to “believe” that man-made climate change is a dire emergency and that government “solutions” are needed.” click here

The “new energy economy” is magical thinking

“This “new energy economy” rests on the belief—a centerpiece of the Green New Deal and other similar proposals both here and in Europe—that the technologies of wind and solar power and battery storage are undergoing the kind of disruption experienced in computing and communications, dramatically lowering costs and increasing efficiency. But this core analogy glosses over profound differences, grounded in physics, between systems that produce energy and those that produce information.” click here

Linear-no-threshold default assumption no longer valid

EPA Administrator Wheeler offers a responsible, measured response on climate change

Hysteria over climate changes is counterproductive. Climate is a dynamic system and is always changing. 

“On the climate change, it is an important issue that we have to be addressing, and we are addressing it, but most of the threats from climate change are 50 to 75 years out.” click here
