Consequences of energy use Climate change quiz (true or false):
1) The greenhouse effect is harmful.2) Climate change is caused by natural processes.3) Scientists are still debating the causes of climate change.
![Page 13: THE ROLE OF SCIENCE IN INFORMING ENERGY LEGISLATION Novem Auyeung 2010 Econ Camp Oct. 13, 2010](https://reader030.vdocuments.net/reader030/viewer/2022032802/56649dfe5503460f94ae6382/html5/thumbnails/13.jpg)
The greenhouse effect keeps our planet warm enough to support life.
![Page 14: THE ROLE OF SCIENCE IN INFORMING ENERGY LEGISLATION Novem Auyeung 2010 Econ Camp Oct. 13, 2010](https://reader030.vdocuments.net/reader030/viewer/2022032802/56649dfe5503460f94ae6382/html5/thumbnails/14.jpg)
Humans are a part of nature. Scientists account for geological, ecological, and
human drivers of climate change in their analyses. Based on multiple, independent lines of evidence, they find that the human activities dominate.
(Karl et al. 2006) (Forster et al. 2007)
![Page 15: THE ROLE OF SCIENCE IN INFORMING ENERGY LEGISLATION Novem Auyeung 2010 Econ Camp Oct. 13, 2010](https://reader030.vdocuments.net/reader030/viewer/2022032802/56649dfe5503460f94ae6382/html5/thumbnails/15.jpg)
The majority of scientific experts and scientific organizations agree on the causes of climate change.
(Anderegg, WRL et al. 2010.)
List of scientific organizations that are convinced of the role of human activity (e.g., fossil fuel combustion and deforestation) in climate change:• 32 national science academies• American Association for the Advancement of Science (AAAS)• American Chemical Society (ACS)• American Geophysical Union (AGU)• European Science Foundation• Federation of Australian Scientific and Technological Societies• National Center for Atmospheric Research• National Oceanic and Atmospheric Administration (NOAA)• Royal Meteorological Society

Science can tell us consequences of different amounts of pollution Science can provide us with probabilities and
information for risk management. Economists can provide us with cost estimates for quantifying risk. Policies are made based what level of risk is acceptable.

Pop Quiz: What is science?
True or False:1. Science is about testing and proving
hypotheses.2. Scientific knowledge can only be
generated through experimentation.3. A scientific hypothesis is an “educated
guess”.

Pop Quiz: What is science?
True or False:1. Science is about testing and proving hypotheses.
False – Hypotheses are only disproven.
2. Scientific knowledge can only be generated through experimentation. False – Scientific knowledge can be generated through
model systems, computer models, observational data.
3. A scientific hypothesis is an “educated guess”. False – Hypotheses are testable answers to scientific
questions. If a “guess” is not testable, then it is not a hypothesis.
