"2018: based on "projections" of climate-change and species loss, "Specifically, I predict that there will be no humans on Earth by 2026"."

"2007: permanent blackouts in cities starting in 2012 due to ;"

"2012: "likely" extinction of humanity by 2030 due to climate-change, and mass die-off by 2020 "for those living in the interior of a large continent"

"Other scientists are specialists. They focus on a narrow topic. They do not consider the entire Earth system in their work..."

"Climate change and its impacts are here. Expect superstorms, extreme heat, high humidity, and increased spread of deadly diseases. Plants and non-human animals will die in ever-larger numbers. Civilisation will fail, leading to greatly exacerbated impacts."

"Im a teacher. I relay evidence. I cite science. Im not relying on a belief system."

"Ive been accused of many things, extremist included. Im merely connecting a few dots based on the work of other scientists. In a culture characterised by willful ignorance and the inability to think critically, these accusations are to be expected."

"Accrding the the 6-month ensemble forecast created by the U.S. Naval Postgraduate School, and ice-free Arctic Ocean will not occur this year. ...[T]his was the same group of professors who incorrectly projected an ice-free Arctic Ocean to occur in 2016, plus or minus 3 years. So they are being very conservative."

"On September 17 of this year we bottom out at... about 4.7 million km2 of ice floating on the Arctic ocean... [T]he forecast has been below the actual data... So this is great news and... I recommend that you track it... because it will give you a good idea [of] when an ice-free Arctic Ocean will occur, and therefore when we are likely to lose habitat for most, if not all species on Earth."

"The cooling resulting from contemporary aerosol masking in total right now is 55% globally, including a lot of that [Overhead: 133%] being on land. This is from... an open access peer reviewed journal... Nature Communications..."

"The aerosol masking effect results from industrial activity, as does planetary warming, so this is an interesting Catch-22. Planetary warming results from es that trap heat, So once the radiation gets through the atmosphere it can warm the soil, and the buildings, and thus the effect, and the planet in general... [G]reenhouse gases trap that heat so that about 30% of it held in the atmosphere... Without the greenhouse effect we wouldnt have life on earth, but... we are well beyond the point at which we can stop... the negative consequences. [Overhead: Tiny particles known as aerosols reflect incoming sunlight back into space before the radiation can warm the planet.] According to professor , which most of us know as being one of the founders of understanding climate change, the aerosols fall out of the atmosphere in about five days."

"Henry Gee is a paleontologist, evolutionary biologist and senior editor at Nature, and he concluded on November 30, 2021 in a paper in Scientific American... in the final line, "If we are going to write about human extinction, wed better start writing now" and the title... is "Humans Are Doomed to Go Extinct." Thats very inconvenient!"
