The Still Unresolved Questions of the Paris Climate Agreement
A guide to the most contentious issues and how theyre discussed in the agreement Climate change is a slow story. The permafrost thaws. The oceans acidify. The cost of solar power falls. And meanwhile humanity keeps adding more greenhouse gases to the atmosphere. The climate worsens slowly, and it will be solved slowly. Its works in time scales years and decades-long, not days or hours. Yet every so often there is an exceptional moment, and we are in one right now. This may be the single most important week for the climate this decade. Thats because right now, in a suburb of Paris, global negotiators are in all-day, all-night talks to try and advance the first major global climate agreement since the 1990s. So far, these highly anticipated talks have gone much better than expected . They have avoided the acrimony and impassable red lines of previous conventions. But thats partly because all the easy problems have been solved. Now only the hard questions remain. Heres a guide to most of them. How much should the world limit warming? The background: In 2009, the worlds nations agreed : The global temperature average should not be allowed to rise more than two degrees Celsius over pre-industrial levels. Since then, study after study has emphasized the dangers of a two-degree-warmed world and the simultaneous difficulty of actually halting climate change there . When Paris began, some observers expected the UN to abandon the two-degree limit in favor of something more realistic. Instead, there are some signs it may embrace a more ambitious target. More than 100 countries, including the United States, have announced support for limiting warming to 1.5 degrees Celsius. Many island nations have declared they cannot accept anything more. China has also signaled its endorsement. Were the UN to follow their lead, it would be a triumph for both activists and the most climate-vulnerable nations even though many scientists , including President Obamas top science advisor , believe keeping warming below 1.5 degrees to be a near impossibility. The text: In the December 9 version of the draft Paris outcome, Article 2, Section 1 deals most directly with temperature limits: How quickly will the world abandon fossil fuels? The background: If humanity hopes to keep warming below 1.5 degrees Celsius by 2100, it must essentially stop emitting greenhouse gases into the atmosphere by 2060, according to a recent study from Nature Climate Change . (Then it must start pulling carbon out of the atmosphere no easy feat .) But should the Paris agreement come out and say that? Delegates are less sure. Small island states want forceful language, like the phrases above which call for zero global [greenhouse-gas] emissions by 2060 or decarbonization as soon as possible after mid-century. But Saudi Arabia says that such a goal is a threat to sustainable development which some interpret as meaning a threat to its oil production. (The head of the Saudi climate delegation also advises the countrys Ministry of Petroleum .) According to The New York Times , petroleum-pumping Venezuela is also skeptical of long-term decarbonization language. The text: In the December 9 version of the draft Paris outcome, Article 3, Section 1 addresses the conferences collective long-term goal: Who should pay for the costs of climate change, and how much should they give? The background: Surprise, surprise: Climate financethat is, who gets money, and who gives itis the most controversial issue at the Paris talks. In order to salvage the 2009 climate talks in Copenhagen, Hillary Clinton pledged that the rich world would mobilize $100 billion to help developing countries make their economies more sustainable and prepare for the storms to come. The key word is mobilize: Unlike traditional foreign aid, where government money is redirected to poorer countries, the U.S. and the E.U. would arrange for billions to flow from a variety of sources, public and private. Does that count? And is the rich world defined strictly as the U.S., E.U., Canada, and Japan ? The United States would prefer for China and Indiatwo wealthy, powerful nations that also contain hundreds of millions of people still in povertyto pitch into that $100 billion target. Yet even as the two talk up their own investment in the developing world at the talks, they blanche at being compelled to join the rich worlds pledge . The text: A great deal of the December 9 version of the draft Paris outcome deals with money, but heres a taste, from Article 6, section 2 : How often should nations check and reassess their emission reductions? The background: Two different mechanisms apply here. The first is stock-taking , when countries will announced how theyve reduced carbon emissions. The draft Paris agreement now says global stock-takes will take place every five years. It also says that the first stocktake will happen in either 2023 or 2024, though the United States wants them to start earlier. The New York Times reports that the U.S. is angling for the first stock-take to come in 2019 or 2021both non-presidential election years. The second is ratcheting , when countries will announce more ambitious emissions reductions. India hopes for ratchet sessions to come every 10 years, saying its short term goal must be lifting its people out of poverty. The U.S. and the Pacific island nations wants countries to ratchet every five years. The text: Article 10 of the the December 9 draft Paris outcome deals with global stocktaking, as do a few other sections: Who should make sure nations meet their reduction goals? The background: The United States wants an outside agency, perhaps similar to the International Atomic Energy Agency, to make sure nations keep the promises they made before the Paris talks to cut emissions . China, India, and other developing countries are skeptical of third-party oversight. In the Times , a former Clinton climate advisor says that the U.S. has increased its climate-finance money to try and gain leverage on the issue, but that the two rapidly developing powers are happy to wait the talks out. The text: Right now, mention of an outside agency does not appear in the Paris draft text. Who is responsible for the loss and damage caused by climate change? The background: As climate change worsens, it will assault not only coastal cities and settlements, but also rural farmers and fishers who depend on predictable seasons and reliable ocean currents. Who should pay for all the infrastructure deluged and harvests lost? In 2013, a UN climate conference began establishing an international loss and damage mechanism to address these concerns. The United States and other developed countrieswhich, after all, have emitted most of the greenhouse gases in the atmosphere right now and thus are responsible for that warmingsay they want to help. But they cannot abide what would amount to climate reparations. The U.S. clearly acknowledges that these impacts are being felt, but it does have a red line around increases of compensation and liability, says Rachel Cleetus, the lead economist at the Union of Concerned Scientists. The text: In the December 9 draft of the Paris outcome , a standalone Article 5 addresses loss and damage: Who bears responsibility for protecting the climate, anyway? The background: In 1992, the world adopted the United Nations Framework Convention on Climate Change . This document has guided all future climate diplomacy: This climate convention in Paris formally meets under its auspices. The framework convention establishes the principle of c ommon but differentiated responsibility for protecting the climate system: That is, everyone has a role to play in keeping the world safe, but highly developed countries have the most responsibility. Now, many developed countries want to make sure this principle is adhered to: the differentiated as much as the common. Theres no single blurb of text to point to that demonstrates this principle, said Cleetus, but developing countries want it to be a common thread through the text. Mitigation commitments, finance commitmentsdeveloping countries were asking for these issues to be seen together, she told me. They needed to be decided together under the convention rather than as one-off agreements on specific pieces of it. In particular, she said, they want any ratchet mechanism for emissions reduction to be tied to increases in finance from developed countries. Developing countries wont agree on an outcome where theyre making agreements to emissions reductions and are not seeing commensurate increases in finance, Cleetus said. The text: Again, no single portion of the December 9 Paris draft outcome addresses these issues. But I was struck by these two adjoining resolutions in the preamble. Theyre both bracketed, which means that neither has a secure place in the final agreement. But they seem almost to argue and rebut each other: The first clause declares: The most developed countries, the global North, are responsible for what became of the climate. But wait, says the second clause: Wouldnt the global South like to follow the North into prosperity? That means it will bear more responsibility soon. And it means, too, that both sides together must decide what the climate becomes now.
