Uncertainty in health impacts of climate change

by Judith Curry Health risks arise from the interaction of uncertain future climatic changes with complex ecological, physical, and socio-economic systems, which are simultaneously affected by numerous other changes, e.g. globalisation, demographic changes, and changes in land use, nutrition, health care quality. Policymaking on … Continue reading

Decision making under uncertainty: the dog and the frisbee

by Judith Curry As you do not fight fire with fire, you do not fight complexity with complexity. Because complexity generates uncertainty, not risk, it requires a regulatory response grounded in simplicity, not complexity. To ask today’s regulators to save … Continue reading

Garth Paltridge held hostage (?) by the uncertainty monster

by Andy Lacis JC note:  this essay responds to Garth Paltridge’s recent post Science held hostage in climate debate. What’s up with Garth? Why the surprisingly out of touch lack of understanding of what it is that makes the global … Continue reading

Psychology of Uncertainty

by Judith Curry When we fail to distinguish between discovering order IN nature and imposing order ON nature, we have lost relationship with the very thing we yearn to know. Whereas once we were students of nature, looking to her for meaning, we now denigrate her … Continue reading

Uncertainty is not your friend (?)

by Judith Curry It is very clear that uncertainty is no one’s friend. We have seen that greater uncertainty about the evolution of the climate should give us even greater cause for concern. We have seen that all other things … Continue reading

Climatic Change special issue on uncertainty guidance for the IPCC: Part II

by Judith Curry Uncertainty abounds in issues related to climate science and climate changes, the impacts of those changes, and the efficacy of strategies that might be used to mitigate or adapt to change. There are, however, a few things about … Continue reading

Hegerl et al. react to the Uncertainty Monster paper

by Judith Curry Gabrielle Hegerl, Peter Stott, Susan Solomon, and Francis Zwiers have published a comment to our paper “Climate Science and the Uncertainty Monster.”  Webster and Curry respond.  The CRU emails provide some interesting context for this discussion. .

Smith and Stern on uncertainty in science and its role in climate policy

by Judith Curry Risk assessment requires grappling with probability and ambiguity (uncertainty in the Knightian sense) and assessing the ethical, logical, philosophical and economic underpinnings of whether a target of ‘50 per cent chance of remaining under +2◦C’ is either … Continue reading

Proc. Roy. Soc. Special Issue on ‘Handling Uncertainty in Science’

by Judith Curry The Royal Society Discussion Meeting on Handling Uncertainty in Science, held 22/23 March 2010, played a seminal role in motivating me to investigate uncertainty in the climate debate.

Critique of the HADSST3 uncertainty analysis

by Judith Curry On the previous sea surface temperature thread, I stated “Do you for one minute believe that the uncertainty in global average sea surface temperature in the 19th century is 0.3C? I sure as heck don’t.” Sharper00 challenged … Continue reading

Uncertainty and the IPCC

Doubt, uncertainty and ignorance

by Judith Curry The word “doubt” has a bad connotation in the climate debate owing to the merchants of doubt meme.  Richard Feynman puts the word “doubt”  into the appropriate perspective in the context of science: When a scientist doesn’t … Continue reading

Uncertainty, risk, and (in)action

by Judith Curry “So when you take uncertainty into account, it actually leads to the decision that we should take action more quickly.” I first spotted the statement in the Discover Magazine interview with myself and Michael Mann .  I thought … Continue reading
