A 2004 meta-analysis of 69 such studies from 1694 until 2001 found the average predicted maximum number of people the Earth would ever have was 7.7 billion people, with lower and upper meta-bounds at 0.65 and 98 billion people, respectively.
Estimates published in the early 2000s tended to predict that the population of Earth would stop increasing around 2070. [17] For example in a 2004 long-term prospective report, the United Nations Population Division projected that world population would peak at 9.2 billion in 2075 and then stabilize at a value close to 9 billion out to as far ...
It has since been set backward 8 times and forward 18 times. The farthest time from midnight was 17 minutes in 1991, and the closest is 89 seconds, set in January 2025. [5] The Clock was moved to 150 seconds (2 minutes, 30 seconds) in 2017, then forward to 2 minutes to midnight in 2018, and left unchanged in 2019. [6]
According to Nasa's Center for Near-Earth Object Studies, Asteroid 2024 YR4 has fallen off the Torino scale after recent observations. The impact probability dropped to 0.0017% or 1-in-59,000 odds ...
The ablation and vaporization caused by Earth's fall on a decaying trajectory towards the Sun may remove Earth's mantle, leaving just the core, which will finally be destroyed after at most 200 years. [102] [103] Earth's sole legacy will be a very slight increase (0.01%) of the solar metallicity following this event. [104]: IIC
In 2024, the experts who maintain the Doomsday Clock said humanity was as close as ever to global catastrophe. The time on the symbolic clock was set at 90 seconds to midnight , the same as in 2023.
Long-range predictions to 2055 range from a population decline to 3.2 billion in the 'low scenario', to 'high scenarios' of 24.8 billion. One scenario predicts a massive increase to 256 billion by 2050, assuming fertility remains at 1995 levels. [6]
Time is flying. Literally. Scientists at the National Physical Laboratory in England recorded the shortest day ever on June 29 and another shortened day on July 26, Popular Mechanics reported.. On ...
