Academic versus professional perspectives

by Judith Curry

What are blogs good for anyways?

by Judith Curry

Cool first, warm later

by Judith Curry

From an article in the New Scientist by Fred Pearce, written in Sept 2009:

One of the world’s top climate modellers said Thursday we could be about to enter one or even two decades during which temperatures cool.

“I am not one of the sceptics,” insisted Mojib Latif of the Leibniz Institute of Marine Sciences at Kiel University, Germany. “However, we have to ask the nasty questions ourselves or other people will do it.”

PBS Ombudsman

by Judith Curry

A segment on climate change last Monday evening produced a storm of protest from critics who felt the program mislead viewers — by a faulty application of journalistic balance — about the very real threat of global warming and man’s contribution to it, as well as a sprinkling of support from those who think that threat is overstated and that balance was just the right touch for the NewsHour. – Michael Getler, PBS

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 adaptation to health risks of climate change thus faces substantial uncertainty. – Wardekker et al.

The costs of tackling or not tackling anthropogenic global warming

by Michael Cunningham (“Faustino”)

There are many issues of debate about global warming.  Has there been warming this century?  Will there be further warming?  If so, will the cause be anthropogenic or other?  What will be the impacts, both positive and negative?  Should we take action to reduce emissions?  How might we proceed, and what are the costs and benefits of various approaches?

Refocusing the debate about advocacy

by Judith Curry

The notion that a scientist is either an advocate or does nothing at all to shape policy is a false dichotomy that has muddied the debate about science and advocacy. – Scott and Rachlow

The weatherman is not a moron

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 us from tomorrow’s crisis using yesterday’s toolbox is to ask a border collie to catch a frisbee by first applying Newton’s Law of Gravity. – Haldane and Madouros
