children inherit. thank you. >> thank you very much, dr. lashof. our next witness is dr. curry. >> i'd like to thank the committee for the opportunity to present testimony this morning. i'm chair of the school of earth and atmospheric sciences at the georgia institute of technology. i've devoted 30 years to conducts research on topics including climate of the arctic, the role of clouds and aerosols on the climate system, and the climate dynamics of extreme weather events. the premise of the president's climate action plan is that there's an overwhelming judgment of science that global warming is already producing devastating impacts. greenhouse warming is a theory whose basic mechanism is well understood, but whose magnitude is highly uncertain. multiple lines of evidence presented in the recent ippc fifth assessment report suggest that the case for anthropogenic warming is weaker than in 2007.
