Absolutely false. We have 150 years of instrumental recordings. They have around 10,000 years of analyzed data via proxy, and more waiting to be sifted through to push that scale even further back. If they didn't, you wouldn't even be able to make your statement, particularly your 2nd/3rd sentences. Just because its not in this simulation, doesn't mean the data doesn't exist. Its not included in this model for very obvious reasons. Its not appropriate given the vastly different methods of obtaining the data.
