“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...”

“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, we'd better start writing now" and the title... is "Humans Are Doomed to Go Extinct." That's very inconvenient!”

“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.”

“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.”

“I've been accused of many things, extremist included. I'm 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.”

“I'm a teacher. I relay evidence. I cite science. I'm not relying on a belief system.”

“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.”

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

“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"”
