Earth’s Greenhouse Effect Has Not Been Enhanced, But Instead Its Impact Has Declined Since 1983

In the satellite era scientists have continued to observe the Earth’s total greenhouse effect (which includes effects from greenhouse gases and clouds) exerting an overall negative impact (cooling) on surface temperatures since the 1980s. This rules out both CO2 and an enhanced greenhouse effect as drivers of global warming.
Earth’s total greenhouse effect impact on climate is realized by the sum of all contributors to it: water vapor, clouds, and the “anthropogenic” greenhouse gases CO2 and CH4.
Given the modern assumption that humans are responsible for global warming due especially to our CO2 and CH4 emissions, it stands to reason that Earth’s downwelling longwave (LWdn) should be increasing and thus the Earth’s greenhouse effect should be enhanced due to the rising greenhouse gases emissions.
