Dr. Judith Curry and Climate

This is a summary of a presentation by Dr. Judith Curry to the House of Representatives a couple of days ago. The full text of her remarks you can find at http://www.judithcurry.com.

STATEMENT TO THE COMMITTEE ON SCIENCE, SPACE AND TECHNOLOGY OF THE UNITED STATES HOUSE OF REPRESENTATIVES Hearing on “The President’s U.N. Climate Pledge” 15 April 2015 Judith A. Curry Georgia Institute of Technology.

Major Points

Recent data and research supports the importance of natural climate variability and calls into question the conclusion that humans are the dominant cause of recent climate change: •

The hiatus in global warming since 1998 • Reduced estimates of the sensitivity of climate to carbon dioxide • Climate models predict much more warming than has been observed in the early 21st century

We have made some questionable choices in defining the problem of climate change and its solution: • The definition of ‘dangerous’ climate change is ambiguous, and hypothesized catastrophic tipping points are regarded as very or extremely unlikely in the 21st century. •

Efforts to link dangerous impacts of extreme weather events to human-caused warming are misleading and unsupported by evidence. •

Climate change is a ‘wicked problem’ and ill-suited to a ‘command and control’ solution • It has been estimated that the U.S. INDC of 28% emissions reduction will prevent 0.03oC in warming by 2100.

The inadequacies of current policies based on the Precautionary Principle are leaving the real societal consequences of climate change and extreme weather events (whether caused by humans or natural variability) largely unaddressed: •

We should expand the frameworks for thinking about climate policy and provide policy makers with a wider choice of options in addressing the risks from climate change. •

Pragmatic solutions based on efforts to accelerate energy innovation, build resilience to extreme weather, and pursue no regrets pollution reduction measures have justifications independent of their benefits for climate mitigation and adaptation.

Short Biography

Judith Curry Professor, School of Earth and Atmospheric Sciences Georgia Institute of Technology Atlanta, GA 30332-0349 curryja@eas.gatech.edu Dr. Judith Curry is Professor and former Chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology and President of Climate Forecast Applications Network (CFAN).

Dr. Curry received a Ph.D. in atmospheric science from the University of Chicago in 1982. Prior to joining the faculty at Georgia Tech, she held faculty positions at the University of Colorado, Penn State University and Purdue University. Dr. Curry’s research interests span a variety of topics in climate; current interests include air/sea interactions, climate feedback processes associated with clouds and sea ice, and the climate dynamics of hurricanes. She is a prominent public spokesperson on issues associated with the integrity of climate science, and is proprietor the weblog Climate Etc. judithcurry.com. Dr. Curry has recently served on the NASA Advisory Council Earth Science Subcommittee, the DOE Biological and Environmental Research Advisory Committee, and the National Academies Climate Research Committee and the Space Studies Board and the NOAA Climate Working Group. Dr. Curry is a Fellow of the American Meteorological Society, the American Association for the Advancement of Science, and the American Geophysical Union. Financial declaration Funding sources for Curry’s research have included NSF, NASA, NOAA, DOD and DOE. Recent contracts for CFAN include a DOE contract to develop extended range regional wind power forecasts and a DOD contract to predict extreme events associated with climate variability/change having implications for regional stability. CFAN contracts with private sector and other non-governmental organizations include energy and power companies, reinsurance companies, other weather service providers, the Natural Resource Defense Council and the World Bank. Specifically with regards to the energy and power companies, these contracts are for medium-range (days to weeks) forecasts of hurricane activity and landfall impacts. CFAN has one contract with an energy company that also includes medium-range forecasts of energy demand (temperature), hydropower generation, and wind power generation. CFAN has not received any funds from energy companies related to climate change or any topic related to this testimony. .
