Hockey Stick and Climate Sensitivity

Click For Summary
SUMMARY

The discussion centers on the relationship between Mann's MBH99 hockey stick graph and the climate sensitivity equation "Delta T = RF*lamba." It questions whether Mann utilized this equation or its variations in reconstructing paleoclimate temperatures from proxy data such as tree rings, ice cores, lake sediments, and corals. Dr. James Powell is recommended as a credible source for further insights, with his informative videos available on YouTube and a responsive contact option for inquiries.

PREREQUISITES
  • Understanding of climate sensitivity equations, specifically "Delta T = RF*lamba."
  • Familiarity with Mann's MBH99 hockey stick graph and its significance in climate science.
  • Knowledge of paleoclimate proxies including tree rings, ice cores, lake sediments, and corals.
  • Basic research skills to access and interpret scientific videos and articles.
NEXT STEPS
  • Research the methodology behind Mann's MBH99 hockey stick graph.
  • Explore the implications of the climate sensitivity equation "Delta T = RF*lamba" in climate models.
  • Investigate the use of paleoclimate proxies in climate reconstruction studies.
  • Watch Dr. James Powell's videos on YouTube for a deeper understanding of the hockey stick graph.
USEFUL FOR

Climate scientists, environmental researchers, students studying climate change, and anyone interested in the methodologies behind paleoclimate temperature reconstructions.

I wonder if you might be able to help me with a question I have about climate change, specifically Mann's MBH99 hockey stick graph in relation to climate sensitivity equation. I would like to know where the climate sensitivity equation "Delta T = RF*lamba fits into the making of the hockey stick graph - did Mann use this equation (or some variation of it) when reconstructing paleoclimate temperatures using proxy data i.e. tree rings/ice cores/lake sediments/corals.

Thanks.

I am not an expert, but at least I can refer you to what I think is a good source of information. Dr. James Powell mentions the hockey stick graph in at least one of his videos, which are available on Youtube, and he may have a more detailed explanation on his site. If not, you can contact him and request some information. I did so myself with a question and he answered fairly quickly. His Bio, which is linked to from his home page, is very impressive.
