A high-powered commission due to launch in May aims to break the silence.<\/p>\n<p>Climate diplomats are finalising a 15-strong lineup of former presidents, ministers and representatives of international organisations to explore options for deep adaptation, carbon dioxide removal (CDR) and geoengineering, Climate Home News can reveal.<\/p>\n<p>The Climate Overshoot Commission will address sensitive questions around the ethics and feasibility of potential ways to reverse warming that are problematic or unproven at large scale.<\/p>\n<p>\u201cThe primary strategy to combat climate change should remain reducing greenhouse gas emissions, but it has also become necessary to explore additional strategies,\u201d Jesse Reynolds, executive secretary of the commission, told Climate Home.<\/p>\n<p>France\u2019s Pascal Lamy, director general of the World Trade Organisation between 2005 and 2013, has been appointed as chair.

Among them, five were from developing countries, including Cop27 host Egypt\u2019s environment minister Yasmine Fouad, former Marshall Islands president Hilda Heine and Youba Sokona, vice-chair of the Intergovernmental Panel on Climate Change (IPCC).<\/p>\n<p>Paris Agreement architect Laurence Tubiana and Janos Pasztor, executive director of the Carnegie Climate Governance (C2G) Initiative, were other members.<\/p>\n<p>\u201cHow will the world manage the risk of temperature overshoot? That is the question that nobody is talking about,\u201d Pasztor told Climate Home. \u201cThere isn\u2019t enough attention paid to the magnitude of the risk for removing the huge amount of carbon dioxide that will keep us to 1.5C.\u201d<\/p>\n<p>With the latest science showing overshoot of 1.5C, if not 2C, is highly likely, the moment for that conversation may have arrived.<\/p>\n<blockquote><p><a href=\"https:\/\/www.climatechangenews.com\/2022\/04\/19\/pakistans-tree-planting-ambition-in-doubt-after-imran-khans-exit\/\"><strong>Pakistan\u2019s<\/strong> tree-planting ambition in doubt after Imran Khan\u2019s exit<\/a><\/p><\/blockquote>\n<p><a href=\"https:\/\/www.nature.com\/articles\/s41586-022-04553-z\" target=\"_blank\" rel=\"noopener\">A paper published in Nature<\/a> last week gives a 6-10% probability of reaching without exceeding the 1.5C threshold, even assuming all climate commitments to 2030 and mid-century are met.<\/p>\n<p>In theory, global temperatures can be pulled back by sucking carbon out of the atmosphere through biological solutions such as reforestation and technological ones like direct air capture.

Earlier this month, online payment processing platform Stripe launched a $925m fund to buy offsets from start-ups that permanently remove carbon dioxide from the atmosphere by 2030.<\/p>\n<p>The <a href=\"https:\/\/frontierclimate.com\/\" target=\"_blank\" rel=\"noopener\">Frontier fund<\/a> is financed by Stripe together with Alphabet, Shopify, Meta and McKinsey. It aims to send a signal to researchers and investors that there is a growing market for these technologies.<\/p>\n<p>Climate scientist Zeke Hausfather, Stripe&#8217;s climate research lead, told Climate Home that understanding what removal technologies could work at scale and driving their cost down was necessary if they are to be used in decades to come.<\/p>\n<p>Elsewhere, Venture capital firm Lowercarbon Capital\u00a0<a href=\"https:\/\/nam12.safelinks.protection.outlook.com\/?url=https%3A%2F%2Flowercarboncapital.com%2F2022%2F04%2F14%2Fclean-up-on-aisle-earth%2F&amp;data=04%7C01%7C%7C2cdb3ab1c0c14002b32108da1e20ac7d%7C961f23f8614c4756bafff1997766a273%7C1%7C0%7C637855422951148276%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&amp;sdata=XietqpmjT8Rec%2FDNwdDKASA5W8BmG8BcCIOMxIAl4II%3D&amp;reserved=0\" target=\"_blank\" rel=\"noopener\">launched a $350m fund<\/a>\u00a0in invest in carbon removal start-ups and Swiss carbon removal company Climeworks <a href=\"https:\/\/climeworks.com\/news\/equity-fundraising\" target=\"_blank\" rel=\"noopener\">raised $650m<\/a> from institutional investors earlier this month.<\/p>\n<p>\u201cBut the private sector can only push things so far,\u201d said Hausfather, suggesting governments help fund research and development of CDR approaches.<\/p>\n<blockquote><p><a href=\"https:\/\/www.climatechangenews.com\/2022\/04\/08\/sweden-set-to-be-worlds-first-country-to-target-consumption-based-emission-cuts\/\"><strong>Sweden<\/strong> set to be world\u2019s first country to target consumption-based emission cuts<\/a><\/p><\/blockquote>\n<p>The issue has been largely ignored at UN Climate Change talks.<\/p>\n<p>For Oliver Geden, a lead author of the IPCC report on mitigation and senior fellow at the German Institute for International and Security Affairs, that\u2019s unlikely to change \u201cuntil there is an acceptance that overshooting 1.5C is unavoidable\u201d.<\/p>\n<p>While \u201cnot a magic bullet,\u201d Geden said countries have already said yes to CDR by adopting net zero emissions targets \u2013 the \u201cnet\u201d being achieved by balancing sources and sinks of emissions.<\/p>\n<p>\u201cI\u2019m of that bottom-up view that countries have a net zero target should and can explore CDR,\u201d he told Climate Home. The alternative top-down approach of sharing out between nations the delivery of removals needed to meet global climate goals brings about considerations of equity and historic responsibility that many wealthy economies are seeking to avoid.<\/p>\n<p>That conversation is uncomfortable for many climate campaigners, who are concerned that a focus on removals is at best a distraction from the need to phase out fossil fuels and roll out clean energy \u2013 and at worse a fig leaf for climate inaction.<\/p>\n<p>\u201cWe urgently need the weight of global financing to invest in a radical overhaul of our polluting energy, food and industrial systems. But tech bros prefer to throw good money after bad into the carbon removal pipedream, letting polluters continue business-as-usual while appearing green,\u201d Teresa Anderson, climate justice lead at Action Aid International, told Climate Home.<\/p>\n<blockquote><p><a href=\"https:\/\/www.climatechangenews.com\/2022\/01\/28\/crypto-bubble-hype-machine-behind-70000-carbon-credit\/\"><strong>Crypto bubble:<\/strong> The hype machine behind a $70,000 carbon credit<\/a><\/p><\/blockquote>\n<p>For MJ Mace, a climate negotiator for the Alliance of Small Island States, there is \u201ca real fear that the pressure comes off emissions reductions\u201d if the issue of removals is pushed too forcefully in the public consciousness.<\/p>\n<p>And yet, if emissions cuts are still lagging behind targets at the end of this decade, \u201cwe are going to end up having to rely on CDR on such a huge scale to meet these goals that we are not going to be able to pull it off\u201d unless investment and planning start now, she said. \u201cIt\u2019s such a dance.\u201d<\/p>\n<p>If removing carbon from the atmosphere is a sensitive subject, solar radiation management, or geoengineering, is even more so. Still largely in the realm of science fiction, the potential to block the sun&#8217;s warming effect by pumping aerosols into the high atmosphere is part of the commission&#8217;s mandate.<\/p>\n<p>Pasztor said solar geoengineering is \u201cunbelievably controversial\u201d but leaders have to consider what risks they are willing to take to meet the 1.5C goal.<\/p>\n<p>The Carnegie Climate Governance (C2G) Initiative, which he heads, is hoping to push a resolution on addressing the risks of overshoot at the UN general assembly by 2023.<\/p>\n","protected":false},"excerpt":{"rendered":"Fifteen former leaders and ministers are set to address sensitive questions on the role of CO2 removal and geoengineering in climate
