TLDR
These guidance notes are intended to assist the Lead Authors of the Fifth Assessment Report (AR5) in the consistent treatment of uncertainties across all three Working Groups as discussed by the authors, which can be used broadly for developing expert judgments and for evaluating and communicating the degree of certainty in findings of the assessment process.Abstract:
These guidance notes are intended to assist Lead Authors of the Fifth Assessment Report (AR5) in the consistent treatment of uncertainties across all three Working Groups. These notes define a common approach and calibrated language that can be used broadly for developing expert judgments and for evaluating and communicating the degree of certainty in findings of the assessment process. These notes refine background material provided to support the Third and Fourth Assessment Reports [1] and [2]; they represent the results of discussions at a Cross-Working Group Meeting on Consistent Treatment of Uncertainties convened in July of 2010 [3]. They also address key elements of the recommendations made by the 2010 independent review of the IPCC by the InterAcademy Council [4]. Review Editors play an important role in ensuring consistent use of this calibrated language within each Working Group report. Each Working Group will supplement these notes with more specific guidance on particular issues consistent with the common approach given here.read more

TL;DR: In this paper, the authors construct decadal budgets for methane sources and sinks between 1980 and 2010, using a combination of atmospheric measurements and results from chemical transport models, ecosystem models, climate chemistry models and inventories of anthropogenic emissions.

Eakin,Ove Hoegh-Guldberg,Ryan P. Kelly,Hans-Otto Pörtner,Alex Rogers,John M. Baxter,D. Laffoley,D. Osborn,Aleksandar Rankovic,Julien Rochette,Ussif Rashid Sumaila,Sébastien Treyer,Carol Turley +22 more
TL;DR: The physics, chemistry, and ecology of the oceans might be affected based on two CO2 emission trajectories: one business as usual and one with aggressive reductions, consistent with the Copenhagen Accord of keeping mean global temperature increase below 2°C in the 21st century.

TL;DR: In this article, a holistic perspective on changing rainfall-driven flood risk is provided for the late 20th and early 21st centuries, which includes an assessment of changes in flood risk in seven of the regions considered in the recent IPCC SREX report.

Catch reconstructions reveal that global marine fisheries catches are higher than reported and declining
Daniel Pauly,Dirk Zeller +1 more
TL;DR: A decade-long multinational ‘catch reconstruction’ project covering the Exclusive Economic Zones of the world's maritime countries and the High Seas from 1950 to 2010, and accounting for all fisheries, suggests that catch actually peaked at 130 million tonnes, and has been declining much more strongly since.

Prospect theory: an analysis of decision under risk
Daniel Kahneman,Amos Tversky +1 more
TL;DR: In this paper, the authors present a critique of expected utility theory as a descriptive model of decision making under risk, and develop an alternative model, called prospect theory, in which value is assigned to gains and losses rather than to final assets and in which probabilities are replaced by decision weights.
