The Earth’s warming is attributed to increased absorption of sunlight due to reduced global cloud cover, as concluded by two researchers. Monthly radiative anomalies from the CERES EBAF 4.2 dataset show the following calculations: (a) Earth’s global albedo is determined by dividing the reflected all-sky shortwave anomaly by the globally averaged incident solar flux at the TOA, then multiplying the result by 100 to convert to a percentage; (b) Earth’s absorbed solar flux is calculated by multiplying the CERES reflected all-sky shortwave anomaly by -1, as radiation absorption is opposite and complementary to reflection.

Sunlight and Clouds, Not CO2, Drives Earth’s Climate, New Study Finds
According to Nikolov, if rising global temperatures were solely due to greenhouse gases, there should have been more warming than what has been observed. He argues that solar forcing alone can explain the entire warming of the 21st century, leaving no room for any anthropogenic forcing.
Nikolov points out that the decrease in Earth’s albedo since 2000, as observed by NASA’s Clouds and the Earth’s Radiant Energy System, has had an impact on recent warming. This observation challenges the discussion in the 2021 IPCC Sixth Assessment Report, which did not address this factor.
NASA addresses the question “Is the Sun causing global warming?” on its website and states that while the Sun can influence Earth’s climate, it is not solely responsible for the warming trend seen in recent decades. The rapid and significant warming observed in recent years cannot be attributed to changes in Earth’s orbit or solar activity.
The IPCC has not provided a response to The Epoch Times’ inquiry regarding Nikolov’s findings at the time of publication.
