That's not quite right. The greenhouse effect was first observed in 1827 and expanded on by many scientist. It was widely acceptable in the early 20th century. The theory simply stated is greenhouse gases, in the atmosphere reflect heat back to the earth thus forming a blanket around the earth. Without these gases the planet would go into a deep freeze. Too much and temperature rises to a point of treating life on the planet.
That isn't quite right either...A greenhouse effect was first thought to have been observed, and was written up in a paper in 1827....shortly afterwards, one professor woods performed a series of experiments and discredited that first paper on the greenhouse effect. He demonstrated that what was thought to have been a greenhouse effect was actually nothing more than blocking of convection by glass panes... The present day climate crisis is based on a failed experiment done in the early 1800's.
No greenhouse effect has ever been observed, or measured in reality...it is all the product of models.
To date, there has not been a single paper published in any scientific journal in which the claimed warming due to our activities has been empirically measured, quantified and ascribed to so called greenhouse gasses. That being the case, exactly where does the certainty that we are altering the global climate come from?

The Greenhouse Effect is demonstrated and observed in just about ever high school in the country.
Similar experiments have been duplicated many times in large atmospheric chambers containing various concentrations of CO2, methane, water vapor, and trace gases. Temperature changes of course vary by concentrations and mixtures but it always shows increases in temperatures compared to the control.
The results are confirmed by measurements at Mauna Loa and Baring Head. In addition the Greenhouse Effect has been used by planetary astronomers to help explain temperature differences between planets. Furthermore every modern weather forecasting model has a radiative transfer model in its core, which is based on the Greenhouse Effect. People who don’t accept the greenhouse effect are simply not dealing with reality.
There is no way to directly measure temperature change in the atmosphere due to burning fossil fuels, deforestation, agriculture, ocean absorption, or other sources because there is no way to isolate a single source. We can calculate the amount of greenhouses gases produced by various sources and thus determine which sources are of greatest concern. However, due to political and economic reasons reducing the greatest contributor may not be possible. In the end, the most important thing is reducing amount of greenhouse gases. How we do it will be a political decision.
