Global Warming

Did former CIA Director John Brennan reveal that the U.S. government uses Stratospheric Aerosol Injection, a hypothetical geoengineering technology, to control the weather? No, that's not true: A full video of his 2016 speech shows that Brennan said no such thing. He was discussing his interest in technologies that could potentially reverse climate change; he did not say that these…

Do two reels posted to Facebook authentically show clips of tornadoes that occurred in Dubai and Canada? No, that's not true: Experts told Lead Stories that the twisters shown in the clips were fake and 100 percent AI-generated content. There are prominent elements in the videos that indicate manipulation and editing have been used to create them. One claim originated…

Did data from December 2023 show that Arctic sea ice had soared to its "highest level for 21 years," thus disproving global warming and climate change? No, that's not true: The blog that made this claim cherry-picked genuine data, a senior research scientist told Lead Stories. While it is true that the total area of the Arctic Ocean covered by…

Are volcanos petrified dragon remnants that "sometimes bubble up," as a post on social media claims? No, that's not true: Volcanos are openings in the earth's surface through which molten rock, gases and ash escape. Dragons -- defined as giant, flying, fire-beathing creatures -- do not exist in real life. The account that created this post says it's satire and…

Was the Earth's average temperature 2 degrees Celsius warmer 55,000 years ago? No, that's not true: Climate experts contacted by Lead Stories all agreed that the Earth's temperature 55,000 years ago was colder than today's average temperature, not warmer. Ice core samples and other geological data show that global temperatures were lower due to extensive ice sheets and lower greenhouse…

Does a warmer average temperature in May 1895 compared to May 2024 disprove global warming, as a post with a chart on social media implied? No, that's not true: Climate experts contacted by Lead Stories said the data was cherry-picked and misleading and that the data chart was altered so as to mislead readers about the long-term trend. Short-term fluctuations…

Was a snow-covered jet frozen on an airport runway in Germany when it was meant to be headed to a "Dubai global warming conference"? No, that's not true: The plane was not scheduled to fly anywhere in the days before or after a massive snowstorm hit Munich, Germany. The jet apparently tipped over due to the weight of the snow…

Did U.S. Rep. Alexandria Ocasio-Cortez suggest that Elon Musk go to the sun to study climate change? No, that's not true: The audio and the visual backdrop of this video clip have been digitally altered. In the real interview that this footage was taken from, on the CBS program "Face the Nation," Ocasio-Cortez did not speak about sending Musk to…

Did the head of the CIA acknowledge in a speech that "chemtrails" are real? No, that's not true: In a 2016 speech then-CIA Director John Brennan was discussing a controversial and untested solar geoengineering method called Stratospheric Aerosol Injection technology. "Chemtrails" are not the same thing as Stratospheric Aerosol Injection, which aims to potentially reverse global warming by reflecting a…

Do potential methane emissions expelled by wild bison populations compare with levels expelled by domestic cows in the U.S. and beyond? No, that's not true: Global populations of bison total less than half a million compared with 1.5 billion cows. An expert in biological systems engineering and agriculture told Lead Stories that the claim's comparison is arbitrary as it does…
