YouTube puts context label on Green Party presidential candidate Jill Stein’s campaign launch video: YouTube imposed a fact-checking label on presidential candidate Jill Stein’s Nov. 22 video, “Jill Stein 2024 Presidential Launch Call.” The video included Stein and three guests discussing her agenda that she referred to as "a pro-worker, anti-war, climate emergency agenda." YouTube put a context label that linked to the United Nations and claimed, “Climate change refers to long-term shifts in temperatures and weather patterns, mainly caused by human activities, especially the burning of fossil fuels.” A 2022 study found that atmospheric CO2 from fossil fuels was too low to cause global warming.
