Recent questions
Is there a direct link between individual projects and global climate changes?
No, according to Dr. Christie, there is no direct link between individual projects and global climate changes. He argues that even if the US ceased to exist, the impact on global climate would be minimal.
Are climate models reliable for predicting climate changes?
Dr. Christie highlights that climate models fail to accurately predict past climate changes and are unreliable for predictions. He questions the validity of using CO2 emissions as a proxy for climate change and emphasizes the importance of observing real-world climate data.
What does Dr. Christie criticize about the social cost of carbon model?
Dr. Christie criticizes the social cost of carbon model for not considering the real benefits of low-cost energy. He argues that the calculation is based on flawed inputs, leading to inaccurate estimations and ineffective climate change mitigation strategies.
Does Dr. Christie challenge the consensus among climate scientists on climate change?
Yes, Dr. Christie challenges the 97% consensus among climate scientists on climate change. He questions the validity of the statistic and emphasizes the need for accurate predictions in understanding the climate system.
What is Dr. Christie's stance on the predictability of climate models?
Dr. Christie highlights the lack of predictability in climate models, showcasing discrepancies between predicted and actual temperature increases. He raises concerns about the foundation of climate policies and emphasizes the need for accurate science before implementing further taxing and regulatory measures.
