Is it true that historical measurement inaccuracies significantly contribute to errors in climate change models?

Yes. Historical measurement inaccuracies, such as biases in sea surface and subsurface ocean temperatures, significantly impact the accuracy and reliability of climate model simulations and predictions.

The analysis

The retrieved papers provide clear empirical evidence that historical measurement issues (e.g., uncorrected sea surface temperatures and XBT depth biases) introduce significant errors or biases into climate model simulations, and correcting these historical inaccuracies is crucial for accurate modeling.

Assessing bias corrections in historical sea surface temperature using a climate model

2005

Demonstrates that uncorrected historical sea-surface temperature data introduce a substantial cold bias in climate model simulations, showing how measurement inaccuracies significantly affect global warming estimates.

Influence of XBT Temperature Bias on Decadal Climate Prediction with a Coupled Climate Model

2011

Shows that incorporating expendable bathythermograph depth bias corrections is necessary to eliminate subsurface temperature biases and improve decadal climate prediction skill.
