Not long ago Dr. Roy Spencer published Version 6 University of Alabama-Huntsville satellite-based global average lower tropospheric temperature (LT) anomaly for June, 2021. It was -0.01 deg. C, down an impressive 0.7°C since the peak in early 2016. As Dr. Spencer’s chart above shows, temperatures are back within the range seen 20 years ago. The […]

China’s climate history includes multiple climate warming and cooling fluctuations of 4°C within centuries, with cold periods aligning with declines in solar irradiance. According to a new study (Zhang et al., 2021), northern China’s coldest temperatures of the last 5000 years occurred 300 calibrated years before present (cal yr BP), coinciding with the Little Ice […]

Analyzing the cyclic nature of solar activity, leading scientists suggest a solar minimum is set to persist until 2050. It’s important to estimate the features of the next solar cycle because they serve to improve preparedness in space exploration and minimizing risks in technological and sociological activities. The ability to understand historical solar magnetic parameters […]

Over the US, the modest change in cloud cover from 1996-2019 predominantly drove the +11.77 W/m² surface solar radiation forcing during 1996-2012 (then -2.35 W/m² from 2013-2019). These “brightening” and “dimming” magnitudes easily overwhelm the values associated with an annual 2 to 2.5 ppm rise in CO2 forcing (0.2 W/m² per decade). When cloud cover […]

A groundbreaking new study in Science suggests warm interglacial-like conditions (surface temperatures within 1°C of today’s) persisted from 54 to 42,000 years ago even though CO₂ levels idled around 200 ppm at that time. A sudden geomagnetic shift that intensified galactic cosmic rays and cloud formation and reduced ozone levels ~42,000 years ago resulted in […]

Two new studies refer to the natural decline in cloud and aerosol reflectivity and consequent rise in incoming solar radiation or sunlight duration as the explanation for warming trends across Europe. CO2 is not even mentioned as a factor in climate change. Scientists point out that, for Europe, “the decrease in cloud cover is caused […]

CO2’s impact on the total net greenhouse effect (GHE) or longwave (LW) forcing trend has been offset by the dominant impact of cloud cover since the 1980s. It is now widely accepted that changes in clouds, naturally driven by changes in atmospheric circulation, “may be the most important parameter controlling the radiation budget, and, hence, […]

A world renowned astrophysicist says the IPCC’s climate warnings cannot be taken seriously and that climate models use tricks to put the blame on CO2 Pierre Heumann at Weltwoche has a feature story on renowned Israeli astrophysicist, Nir Shaviv, professor at the Racah Institute of Physics, Hebrew University of Jerusalem. Hebrew University astrophysicist, Prof. Nir Shaviv. […]

In 2020, more than 400 scientific papers were published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources. Over 400 scientific papers published in […]

Oceans cover 71% of the Earth’s surface. An analysis of CO2’s radiative effect on ocean temperatures finds CO2 forcing is negligible even after reaching a concentration of 1,071 ppm. In the tropical oceans, 500 to 1,000 W/m² of solar radiation uniformly heats the first 2 meters of the ocean surface by 2 Kelvin in a […]

Hundreds of publications show how climate in many regions around the world varies in sync with solar activity. More evidence is provided by Japanese climate scientist Kyoji Kimoto. ======================================= Climate Change Governed By The Sun By guest author Kyoji Kimoto, kyoji@mirane.co.jp January 22, 2021 I’ve compiled a list of six examples how the sun impacts […]

European winter temperature variability is “dominated” by the North Atlantic Oscillation (NAO), which is, in turn, modulated by solar activity. Even proponents of anthropogenic global warming (AGW) agree natural processes (AMO, NAO, ENSO, solar forcing, volcanism) drive temperature variability. But they insist the rising temperature trend is human-caused. So if we don’t have a regional […]
