Today marks the five year anniversary of the doomsday prediction climate change hoaxer Greta Thunberg made, in which she claimed all humanity would be wiped out within five years if we didn’t stop using fossil fuels.
On June 21, 2108, Thunberg tweeted, “A top climate scientist is warning that climate change will wipe out all of humanity unless we stop using fossil fuels over the next five years.”
Thunberg shared a Grit Post article by Scott Alden (which has since been deleted), referencing a prediction from James Anderson, an atmospheric chemistry professor at Harvard University. The article was titled “Top Climate Scientist: Humans Will Go Extinct if We Don’t Fix Climate Change by 2023,” emphasizing the urgent need for action.

In a recent speech at the University of Chicago, James Anderson — a professor of atmospheric chemistry at Harvard University — warned that climate change is drastically pushing Earth back to the Eocene Epoch from 33 million BCE, when there was no ice on either pole. Anderson says current pollution levels have already catastrophically depleted atmospheric ozone levels, which absorb 98 percent of ultraviolet rays, to levels not seen in 12 million years.
Anderson’s assessment of humanity’s timeline for action is likely accurate, given that his diagnosis and discovery of Antarctica’s ozone holes led to the Montreal Protocol of 1987. Anderson’s research was recognized by the United Nations in September of 1997. He subsequently received the United Nations Vienna Convention Award for Protection of the Ozone Layer in 2005, and has been recognized by numerous universities and academic bodies for his research.
Anderson’s prediction of Arctic sea ice disappearing by 2022 may be closer to reality than a lot of us would hope. In 2016, University of Reading professor Ed Hawkins compiled global temperature data dating back to 1850, prior to the Industrial Revolution of the early 20th century and the oil boom, and turning the data into a time-lapse GIF. The most alarming part of the data showed that temperatures began rising exponentially faster at the start of the 21st century and show no signs of slowing down.
