2013 - AR5
UNFCCC
a.k.a. “UNF-Triple C” United Nations Framework Convention on Climate
Change
• International treaty signed by 192 countries • Entered into force 21 March 1994 • To consider what can be done to reduce (mitigate) global
warming and cope with (adapt to) inevitable change • Many nations signed an addition to the treaty: the Kyoto
Protocol
![Page 5: GEOG 401 Climate Changeclimate.socialsciences.hawaii.edu/Courses/GEOG401/GEOG... · 2016. 4. 14. · • To consider what can be done to reduce (mitigate) global warming and cope](https://reader035.fdocuments.us/reader035/viewer/2022071503/6122baca7d34603061510175/html5/thumbnails/5.jpg)

Kyoto Protocol • Text adopted at the 3rd COP session in Kyoto, Japan on 11 December
1997
• Difference between UNFCCC and Kyoto Protocol: – Convention encouraged countries to stabilize GHG emissions – Protocol commits them to do so
• 84 countries signed the Protocol including the USA • Entered into force on 16 February 2005, 90 days after ratification by at
least 55 parties to the Convention, which accounted for at least 55% of the total carbon dioxide emissions for 1990
• Ratified by 189 countries. One signatory country has not ratified: USA

Role of IPCC
• First Assessment Report served as the basis for negotiating UNFCCC
• Relationship between IPCC and UNFCCC has continued and serves as a model for interaction between science and policy makers
IPCC’s Keys to Success
• Policy relevant, but not policy prescriptive
• Emphasis on scientific integrity, openness, and transparency
• Rigorous review process involving many experts and open to all member governments
• Enthusiasm and cooperation of thousands of experts who serve as authors and reviewers

From Talk by Carola Saibante, IPCC Information Officer
Reaction to IPCC
• Widely praised as a model of scientific collaboration
• Lauded for unprecedented achievement
• Nobel Peace Prize 2007
• IPCC has also been criticized

Criticisms and Controversies
• Current approach not effective: warnings have attracted attention and the work garnered awards, but has not to led to effective action
• Assessment reports watered down to lowest common denominator: member governments must approve line by line
• Can’t keep pace: explosion of climate research cannot be quickly assimilated under current IPCC procedures
Not Doing Enough
Criticisms and Controversies
• Cherry-picking studies to play down uncertainties: a relatively small group of scientists feel that studies opposing the mainstream view are not given enough weight – Hurricane (typhoon) activity
– Hockey stick graph
Doing Too Much
![Page 11: GEOG 401 Climate Changeclimate.socialsciences.hawaii.edu/Courses/GEOG401/GEOG... · 2016. 4. 14. · • To consider what can be done to reduce (mitigate) global warming and cope](https://reader035.fdocuments.us/reader035/viewer/2022071503/6122baca7d34603061510175/html5/thumbnails/11.jpg)

Criticisms and Controversies
• Political interference: objectivity has been called into question because of vetting of reports by governments
• Too conservative: reports tend to understate dangers; fail to report on issues of potentially great importance, because of scientific uncertainty
• Reports are immediately outdated: mandate for periodic comprehensive report and the thorough review process delay the release until well after the original research
Approach Flawed
AR5 and Beyond • Refocusing scientific priorities
(See: IPCC. 2009. Chairman’s Vision Paper. AR5 Scoping Meeting, July 2009. http://www.ipcc.ch/scoping_meeting_ar5 /documents/doc02.pdf )
• Continuing march toward improved understanding
• Gradual reduction in uncertainty • Structural changes?
– More focused, expeditious reports? – Report dangers that are still highly uncertain? – Constant updating using Wikipedia-style
system? – More attention to psychology/sociology of risk
response?

Risk Response
How Are We Doing?
• Kyoto countries are having a hard time meeting commitments
• Emissions and concentrations continue to rise

FAQ 2. 1, Fi gur e 1
IPCC: Evidence of the Impacts of Global Warming Accumulates
Yet public perception and political will lag. Why?

IPCC: Future Changes May Be Catastrophic If We Continue On
Present Course
Yet public perception and political will lag. Why?
Why No Significant Response • Science is hard • Powerful interests feel threatened by
possible response strategies; try to confuse issue
• Scientists need to do a better job of explaining complex issues
• Media need to do a better job of informing public and reducing bias in coverage
What Needs To Be Done
![Page 15: GEOG 401 Climate Changeclimate.socialsciences.hawaii.edu/Courses/GEOG401/GEOG... · 2016. 4. 14. · • To consider what can be done to reduce (mitigate) global warming and cope](https://reader035.fdocuments.us/reader035/viewer/2022071503/6122baca7d34603061510175/html5/thumbnails/15.jpg)

Journalistic Balance • Journalistic fairness requires presentation of
competing points of view
• Works well to check biased reporting of political or social issues
• For scientific reporting, it demands that competing views be presented as though they had equal scientific validity, when they actually do not
• Results in systematic informational bias
See: Jules & Maxwell Boykoff, Journalistic Balance as Global Warming Bias. Fair, http://www.fair.org/index.php?page=1978
Concluding Thoughts
• Science will continue to improve understanding
• Uncertainties will remain
• Public must recognize the urgency, but also understand that acting soon will make a difference
• Policy makers must find the will to act, despite uncertainties
• Journalists are key players who need to be knowledgeable about climate change

Something to Ponder
To what degree should scientists become activists for policy changes to combat global warming?
