Paragraph: It's true that Shell Oil Companywarned about the dangers of climate change in a video produced by the company in 1991. The 28-minute video described scientific efforts to gather data from the Earth's atmosphere and oceans to better understand climate change. The narrator explained how scientists'views of climate change's impact had evolved by the end of 1990:"What they see is not a steady and even warming overall, but alterations to the familiar patterns of climate, and the increasing frequency of abnormal weather. No two scenarios fully agree. But their strange, mesmerizing images of possible futures have each prompted the same serious warning, a warning endorsed by a uniquely broad consensus of scientists in their report to the United Nations at the end of 1990." [embedyt] https://www.youtube.com/watch?v=vTlYYlRN0LY[/embedyt] The video resurfaced in February 2017 when the Guardianand Wiredboth publishes stories on the 1991 film, "Climate of Concern." The Guardian reported that "Shell knew" about the dangers of climate change for more than 26 years and had failed to take sufficient action to address it: But, despite this early and clear-eyed view of the risks of global warming, Shell invested manybillions of dollars in highly polluting tar sand operations and on exploration in the Arctic. It alsocited fracking as a"future opportunity"in 2016, despiteits own 1998 datashowing exploitation ofunconventional oil and gas was incompatible with climate goals. The film was obtained bythe Correspondent, a Dutch online journalism platform, and shared withthe Guardian, and lauds commercial-scale solar and wind power that already existed in 1991. Shellhas recently lobbied successfully toundermine European renewable energy targetsand isestimated to have spent$22m in 2015 lobbying against climate policies. The company'sinvestments in low-carbon energy have been minimal compared to itsfossil fuel investments. Shell has also been a member of industry lobby groups that have fought climate action, includingthe so-called Global Climate Coalition until 1998; the far-rightAmerican Legislative ExchangeCouncil(Alec) until 2015; and remains a member of the Business Roundtable and the AmericanPetroleum Institute today. On its website, Shell describes the company's current positions on climate change. The company acknowledges hat it remains "primarily an oil and gas company,"but adds,"we know thatlong-term success depends on our ability to anticipate the types of energy and fuels people will need in thefuture and remain commercially competitive and environmentally relevant": Shell has long recognised the climate challenge and the role of energy in enabling a decent quality of life. Webelieve that, while technological developments will emerge, effective policy and cultural change is essential todrive low-carbon business and consumer choices and opportunities. The transition to low-carbon solutions isbest underpinned by meaningful government-led carbon "pricing" mechanisms. We welcome the efforts made by governments to cooperatively reach the global climate agreement and supportlong-term climate goals that balance environmental pressures with development opportunities. The ParisAgreement of December 12, 2015, could provide greater certainty about how the world can provide more energywith much less CO2. So, reports about Shell Oil Company warnings about climate change are true. Comments Claim: Shell Oil Company released a 1991 video about the "catastrophic risks"of climate changethat warned about rising carbon dioxide levels in the atmosphere, climate refugees,
Output:
Warning from Shell Oil Company About Climate Change.
