In 2023, the global mean temperature soared to almost 1.5K above the pre-industrial level, surpassing the previous record by about 0.17K. Previous best-guess estimates of known drivers including anthropogenic warming and the El Niño onset fall short by about 0.2K in explaining the temperature rise. Utilizing satellite and reanalysis data, we identify a record-low planetary albedo as the primary factor bridging this gap. The decline is apparently caused largely by a reduced low-cloud cover in the northern mid-latitudes and tropics, in continuation of a multi-annual trend. Further exploring the low-cloud trend and understanding how much of it is due to internal variability, reduced aerosol concentrations, or a possibly emerging low-cloud feedback will be crucial for assessing the current and expected future warming.
Good for you! Shame you missed the previous piece on the AMOC collapse. — unenlightened
That information comes from climatologists, the same ones who say we're already in AGW. — frank
So the lecture is not denying AGW.

Yeah, we knew about fossil fuel burning producing CO2 and that CO2 was a greenhouse gas back in the 19th century. — Mikie
Climate-change/global-warming alarmists have been scaremongering and warning of impending doom for well over 100 years. Like most doomsday cults, when the predicted disaster doesn't happen when it was predicted they just shift the date of disaster to some time in the future. — Agree-to-Disagree
Come back in another century and sneer about failed doomsday cults. — unenlightened
In 1982, Mostafa Tolba, executive director of the UN’s Environment Program, pointed to the possibility of widespread devastation in less than 20 years. He cited “an environmental catastrophe which will witness devastation as complete, as irreversible as any nuclear holocaust.”
On June 30, 1989, the Associated Press squeezed decimation into a tight, 11-year window, with an ominous article, “Rising Seas Could Obliterate Nations,” containing a jaw-dropping opener: “A senior UN environmental official (Noel Brown) says entire nations could be wiped off the face of the Earth by rising sea levels if the global warming trend is not reversed by the year 2000.”
In 1990, aware the apocalypse was stalled, Mostafa Tolba, doubled down: “We shall win or lose the climate struggle in the first years of the 1990s. The issue is as urgent as that.”
In February 1993, Thomas Lovejoy, assistant secretary for Environmental and External Affairs at the Smithsonian Institution, stressed the world had one remaining decade of opportunity to avoid calamity. “I am utterly convinced that most of the great environmental struggles will be either won or lost in the 1990s and by the next century it will be too late.”
The 1990s was a steady chain of doomsday assurances, but the heaviest hyperbole was yet to be unleashed.
Cannibals, Toast, and Chaos
In 2006, former vice-president Al Gore projected that unless drastic measures were implemented, the planet would hit an irreversible “point of no return” by 2016. Game over.
Rajendra Pachauri, head of the UN Climate Panel, one-upped Gore in 2007, insisting 2012 was the year of irreversibility. “If there is no action before 2012, that’s too late. What we do in the next two to three years will determine our future. This is the defining moment.”
In April 2008, media mogul Ted Turner provided far more detail than either Gore or Pachauri, emphasizing the consequences of climate inaction. “Not doing it will be catastrophic. We’ll be eight degrees hotter in ten, not 10 but 30 or 40 years and basically none of the crops will grow. Most of the people will have died and the rest of us will be cannibals. Civilization will have broken down. The few people left will be living in a failed state like Somalia or Sudan, and living conditions will be intolerable. The droughts will be so bad there’ll be no more corn growing.”
The acclaimed godfather of global warming, James Hansen, drew a line in the sand testifying before Congress in June 2008, on the dangers of greenhouse gases: “We’re toast if we don’t get on a very different path. This is the last chance.”
A year later, in July 2009, then-Prince Charles chimed in, asserting the planet had 96 months to avoid decimation: “…irretrievable climate and ecosystem collapse, and all that goes with it.”
Only three months later, UK prime minister Gordon Brown urged nations to pull a historical handbrake ahead of a climate conference: “There are now fewer than 50 days to set the course of the next 50 years and more. If we do not reach a deal at this time, let us be in no doubt: once the damage from unchecked emissions growth is done, no retrospective global agreement, in some future period, can undo that choice. By then, it will be irretrievably too late.”
In 2014, French foreign minister Laurent Fabius upped Brown’s 50 days to 500. “We have 500 days to avoid climate chaos.”
Twelve years to 2031. In January 2019, Rep. Alexandria Ocasio-Cortez put her chips on 2031 as the potential end of days. “Millennials and people, you know, Gen Z and all these folks that will come after us are looking up and we’re like: ‘The world is gonna end in 12 years if we don’t address climate change and your biggest issue is how are we gonna pay for it? And, like, this is the war—this is our World War ll.”
Eleven years to 2030. Echoing Ocasio-Cortez in March 2019, but shaving off a year, UN General Assembly President Maria Garces declared an 11-year window to escape catastrophe: “We are the last generation that can prevent irreparable damage to our planet.”
In June 2019, then-presidential candidate Joe Biden threw his support behind Ocasio-Cortez’s dozen-year projection: “Science tells us that how we act or fail to act in the next 12 years will determine the very livability of our planet.”
Full circle back to 2023, and the UN’s latest “time-bomb,” released March 20, as described by the Associated Press: “Humanity still has a chance close to the last to prevent the worst of climate change’s future harms…”
In step with near annual UN declarations from the past 50 years, Secretary-General Guterres once again sounded the alarm: “The climate time-bomb is ticking.”
But therein lies the beauty of doomsday predictions: When one fails, make another. — Chris Bennett
