Swedish teen activist Greta Thunberg turned to Twitter Thursday to thank a key fossil fuel leader for suggesting that climate campaigners—including youth who have joined the global \u0022Fridays for Future\u0022 movement Thunberg inspired with her school strikes outside Sweden\u0026#039;s parliament last year—greatly threaten the oil sector.\u0022Thank you!\u0022 tweeted Thunberg, whose climate leadership earned her a nomination for the Nobel Peace Prize this year. \u0022Our biggest compliment yet!\u0022“There is a growing mass mobilisation of world opinion... against oil\u0022 and this is \u0022perhaps the greatest threat to our industry\u0022.OPEC calls the school strike movement and climate campaigners their “greatest threat”.Thank you! Our biggest compliment yet!https://t.co/f3anMLo4XX— Greta Thunberg (@GretaThunberg) July 4, 2019Earlier this week, after a meeting of the Organization of the Petroleum Exporting Countries (OPEC) in Vienna, the organization\u0026#039;s Secretary-General Mohammed Barkindo reportedly claimed that \u0022unscientific\u0022 attacks by climate activists are \u0022perhaps the greatest threat to our industry going forward.\u0022According to the Agence France-Presse report which Thunberg linked to on Twitter:Barkindo said that as extreme weather events linked to the climate crisis became more common, \u0022there is a growing mass mobilization of world opinion... against oil.\u0022\u0022Civil society is being misled to believe oil is the cause of climate change,\u0022 he said....[H]e said children of some colleagues at OPEC\u0026#039;s headquarters \u0022are asking us about their future because... they see their peers on the streets campaigning against this industry.\u0022Barkindo added that the \u0022mobilization\u0022 against oil was \u0022beginning to... dictate policies and corporate decisions, including investment in the industry.\u0022Although he did not mention any specifics, Barkindo also said that \u0022we believe this industry is part of the solution to the scourge of climate change.\u0022OPEC\u0026#039;s mission \u0022is to coordinate and unify the petroleum policies of its member countries and ensure the stabilization of oil markets in order to secure an efficient, economic and regular supply of petroleum to consumers, a steady income to producers, and a fair return on capital for those investing in the petroleum industry.\u0022The energy organization\u0026#039;s 14 member nations are Algeria, Angola, Congo, Ecuador, Equatorial Guinea, Gabon, Iran, Iraq, Kuwait, Libya, Nigeria, Saudi Arabia, United Arab Emirates, and Venezuela.Bill McKibben, co-founder of the advocacy group 350.org, tweeted a message to activists Thursday in response to the OPEC chief\u0026#039;s remarks: \u0022Wow! Wow! Wow! ...Thanks everyone for your good work!\u0022Barkindo\u0026#039;s comments come as the youth movement—also commonly called #SchoolStrikeForClimate—is planning a worldwide strike for September, and amid mounting research on how the fossil fuel industry endangers the planet. A study published in the journal Nature on Monday warned that existing dirty energy infrastructure jeopardizes the Paris climate agreement target of limiting warming to 1.5°C above pre-industrial levels.\u0022The new study reiterates that visionary climate solutions must justly transition away from fossil fuels, starting with an acknowledgement that 1.5°C carbon budgets must account for planned and new emitting projects,\u0022 Tamara Toles O\u0026#039;Laughlin, North America director for 350.org, said in a statement Wednesday.\u0022This report reinforces the need for complete economic restructuring by way of a Green New Deal that creates millions of jobs for workers in a 100 percent renewable economy and actively keeps fossil fuels in the ground,\u0022 she added. \u0022We stand by the science, and furthermore demand that fossil fuel billionaires pay for the damage they have caused to people and planet.\u0022This post has been updated with comment from Bill McKibben, co-founder of 350.org.
