Why do long-term climate models continue to be so wrong? Because the earth’s climate is too complex to be accurately predicted. 

Climate models have particular trouble dealing with one key factor: water, which impacts the climate far more than CO2.

Inconvenient fact: Climate scientists often fudge measurements of ocean temperatures through dubious recording methods. 

One reason we can’t predict what effect the atmosphere is going to have on future temperatures is that we can’t predict cloud formations. 

Climate models simply cannot accurately predict how the oceans and atmosphere will interact over long periods of time on a planetary scale. 

Global warming based on increased CO2 levels is a hypothesis. It is impossible to test using controlled experiments.

No rational person should believe that computer models can precisely predict temperatures decades from now.

No climate model is complex enough to take into account all the variables that impact planetary climate.

If a climate model doesn’t line up with reality, scientists can “tune” results to produce any outcome they want. 

Inconvenient fact: Climate models that line up more closely with physical evidence predict much less warming than unvalidated models.
