"UH OH!"

"It is no secret to savvy climate modelers that their models are not capable of accurately predicting future climate change."

Airborne Bacteria Discredit Climate Modeling Dogma

The formation of low-level clouds—clouds that have a cooling effect on Earth's climate—has vexed climate scientists for years. Current climate models treat cloud cover simplistically and make the assumption that cloud cover decreases as temperatures rise.

New data from a cloud sampling experiment indicates that biological material—bacteria, spores and plant material—may account for 1/3 of the airborne material involved in cloud formation. Furthermore, biological material can form clouds at much warmer temperatures than mineral dust. These new discoveries indicate that modelers have the effects of temperature on low cloud cover backwards, placing all model predictions in doubt.More...
