This brief opinion piece draws upon behavioural and cognitive research to argue that the Paris Agreement's goal of keeping global temperature change below 2 degrees Celsius sets a psychologically powerful baseline against which future policy failures can be measured. When international law successfully triggers perception of a baseline, it can lead decision makers to perceive deviations from that baseline as “losses.” This implicates loss aversion, which provides an additional motivation to achieve international norms. The psychological impacts of this new status quo may end up being more powerful and more durable than either the unusual structure of the document or the domestic implementation questions that have already attracted so much scholarly debate.

2 The Protocol's ratification process was fraught with political controversy and did not happen until 2005. See http://unfccc.int/resource/docs/convkp/kpeng.pdf.
3 See, e.g., http://www.theguardian.com/environment/2009/dec/18/copenhagen-deal; see also http://www.bbc.com/news/science-environment-34274461 (suggesting that even the word “Copenhagen” was a “word that dare not be uttered” by anyone at the Paris meeting; a disaster that “still haunts the process six years on”).
4 Perhaps most critically, the United States and China entered into a bilateral agreement to reduce emissions, see https://www.whitehouse.gov/the-press-office/2015/09/25/us-china-joint-presidential-statement-climate-change.

7 The practical challenges are recognized even within the decision that adopts the Paris Agreement, see paragraph 17 (“Notes with concern […] that much greater emission reduction efforts will be required than those associated with the intended nationally determined contributions in order to hold the increase in the global average temperature to below 2 °C above pre-industrial levels […] or to 1.5 °C above pre-industrial levels […]”)

9 See e.g. Article 2(2) (“This Agreement will be implemented to reflect equity and the principle of common but differentiated responsibilities and respective capabilities, in the light of different national circumstances.”) and Article 4(1) of ibid (“In order to achieve the long-term temperature goal set out in Article 2, Parties aim to reach global peaking of greenhouse gas emissions as soon as possible, recognizing that peaking will take longer for developing country Parties, […] on the basis of equity, and in the context of sustainable development and efforts to eradicate poverty.”)

14 The structure of the Paris Agreement is rather idiosyncratic, with the actual Agreement placed in an Annex to a COP decision.

18 See Russell Korobkin, Inertia and Preference in Contract Negotiations: The Psychological Power of Default Rules and Form Terms, 51 Vand. L. Rev. 1583 (1998) (finding that the substance of legal default rules can create status quo bias in the direction of the legal rule).
19 An interesting question—beyond the scope of this piece—is the extent to which cognitive phenomena affect nation states as a group, as opposed to merely the individual decision-makers within those nation states. At least some empirical research suggests that group-based decision-making can often exacerbate the underlying biases of individuals. See, e.g., Cass Sunstein, Deliberative Trouble? Why Groups Go to Extremes, 110 Yale L.J. 71 (2000).
20 See, e.g., Richard H. Thaler, Toward a Positive Theory of Consumer Choice, 1 J. Econ. Behav. & Org. 39 (1980) (describing the endowment effect);
21 See Kahneman, Daniel & Tversky, Amos, Prospect Theory: An Analysis of Decision Under Risk, 47 Econometrica 263 (1979)CrossRefGoogle Scholar (noting that the tendency of people to overweight certain outcomes and underweight probabilistic outcomes may lead people to accept overly high risks in the hopes of avoiding a certain loss); Amos Tversky & Daniel Kahneman, Loss Aversion and Riskless Choice: A Reference-Dependent Model, 106 Q. J. Econ. 1039 (1991); see also Russell Korobkin, Behavioral Economics, Contract Formation, and Contract Law, in Behavioral Law and Economics at 116 (2000) (describing the perceived relationship between status quo bias and the endowment effect).
22 The combination of these effects underlies most of the most wellknown behavioural “nudges” of the past decade. See, e.g., Richard Thaler & Shlomo Benartzi, Save More Tomorrow: Using Behavioral Economics to Increase Employee Saving, 112 J. of Pol. Econ. 164 (2004) (advocating for the use of default rules to take advantage of people's preference for the status quo to encourage additional saving behaviours).
23 Although scholars occasionally mention the status quo in international law, this seems generally to be in the colloquial sense rather than in the psychological sense. See, e.g., Guzman, Andrew T. and Meyer, Timothy L., International Soft Law, (2010) 2 (1) Journal of Legal Analysis 171–225 CrossRefGoogle Scholar. We find only one substantive discussion of status quo bias in the international legal literature: an interesting treatment by T. Broude, which focuses on the barriers status quo bias can create in reaching international agreements, and which does not discuss the potential impact of international law on creating perceived status quos. See T Broude, Behavioral International Law, (2015) 163 University of Pennsylvania Law Review 1099.
