Share this…FacebookTwitterAnother new paper published in Paleoceanography and Paleoclimatology casts further doubt on the paradigm that says CO2 has historically been a temperature driver. Evidence from the tropical Atlantic indicates today’s regional temperatures (15.5°C) are 7.5°C colder than a peak temperatures (23°C) between 15,000 to 10,000 years ago, when CO2 hovered around 220 ppm.

Presuming that higher CO2 emissions lead to global warming, it can consequently be said that coral reefs are heating […]

Evidence from southern California’s Lake Elsinore indicates today’s regional temperatures (18°C) are 4-5°C colder than a millennial-scale period between 29,000 to 26,000 years ago (29 to 26 ka), or […]

A new study finds models have significantly underestimated the greening effect of rising CO2. Image Source: Winkler et al., 2019 CO2 is a pollutant?

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 […]
