Models and theories are what enabled us to develop all our technological progress. Before, there was random chance and tinkering. That changed when we started doing experiments and to model theories that fit the measurements. These theories made predictions which enabled us to see whether the model was actually valid. Data is worthless if you have no model to plug it in to make predictions from it.

Beside that there are desktop experiments that are so simple that you could almost do them at home that show that the ability of an atmosphere to capture heat is influenced by its carbon dioxide content. These experiments were done over a hundred years ago.
