Share this…FacebookTwitterThe Earth has been rapidly greening in recent decades, and CO2 fertilization may explain 70% of the trend (Zhu et al., 2016). A new study finds models have significantly underestimated the greening effect of rising CO2. Image Source: Winkler et al., 2019 CO2 is a pollutant? In recent years, carbon dioxide (CO2), an essential […]

Share this…FacebookTwitterAccording to the calculations of Dr. James Hansen, the radiative influence derived from the increase in CO2 during the last deglaciation was so negligible that it equated to “a third of energy required to power a honey bee in flight” (Ellis and Palmer, 2016).

Recent studies have found the favored “renewable” energies – wind and solar – are not effective, even counteractive, when it comes to reducing emissions from fossil fuels. Solar PV installation, for example, results […]

Share this…FacebookTwitterAn empirical analysis using 2005-2015 data from 15 EU countries indicates that as more renewable energies (i.e., solar PV) are deployed, energy costs increase, household poverty risks rise, and incomes decline. Image Source: Pereira et al., 2019 In contrast to the negative consequences of switching from fossil fuels to renewables, Dr. Tadesse Weldu Teklu […]

Share this…FacebookTwitterA new paper indicates the rise in CO2 concentration occurred well after the Northern Hemisphere’s ocean circulation changes drove the abrupt warming (~11,700 years ago) that ended the last ice age – a lag that effectively leaves no causal role for CO2 during deglaciation.

Scientists have found the greenhouse effect’s (GHE) influence on planetary temperatures went on “hiatus” during 1992-2014. The estimated GHE radiative influence for these 22 years was a slightly negative -0.04 […]

Share this…FacebookTwitterIn a new paper, two astrophysicists shred the IPCC-preferred and model-based PMOD solar data set and affirm the ACRIM, which is rooted in observation and shows an increase in total solar irradiance (TSI) during the 1980-2000 period. They suggest a “significant percentage” of recent climate change has been solar-driven. Scafetta and Willson, 2019 I. […]

More and more, scientists aren’t hiding statements or graphical depictions of the lack of modern warming or the much-warmer Holocene past. A compilation of 35 papers from across the globe indicate that modern climate is not unusual, remarkable or unprecedented, and that large regions of the […]

Because CO2 concentrations changed very modestly during the pre-industrial Holocene (approximately ~25 ppm in 10,000 years), climate models that are predicated on the assumption that […]

Since 1930, seawater pH trends have risen slightly, meaning sharply rising CO2 has been coincident with less, not more, ocean “acidification”.
