Notable predictions and known events
- The interaction of the three main decadal solar cycles suggests an upcoming reduction in solar activity, with a low-energy period centered around 2020.[1] As suggested by John Maddox of Nature, this might mitigate the global warming (at least temporarily) in the 2010s and 2020s.[2]
- Assuming that the Atlantic multidecadal oscillation runs through a 70-year quasi-cycle (after peaks in ≈1880 and ≈1950), its current warm phase is likely to peak during this decade.[3][4]
- Each of ESA (Europe),[5] CNSA (China),[6] FKA (Russia),[7] and ISRO (India)[8] plan to send a manned mission to the Moon in this decade.
- Voyager 2 is expected to stop transmitting back to Earth in the 2020s.[9]
- Futurist Ray Kurzweil puts 2029 as the year most likely for a breakthrough in Artificial General Intelligence (AGI). He expects that around this time, computers will reach human intelligence levels, and shortly thereafter surpass the capabilities of the human brain.[10]
- Intel predicts the performance of supercomputers to reach zettaflops scale by 2029.[11]
- Near-Earth Asteroid 99942 Apophis will pass Earth within the orbits of geosynchronous communication satellites on Friday, April 13, 2029,
- By the end of the decade, world population is projected to surpass 8 billion people, half a billion more than 2020, representing a slowdown in growth from the '10s, which are expected to increase the population by 700 million.[12]
In popular culture
- The majority of the Star Trek: Deep Space Nine two-part story "Past Tense" takes place between August 30 and September 3, 2024.
- Half-Life 2 takes place between May 15, 202X and May 30, 202X.
- Deus Ex: Human Revolution takes place in the year 2027.
- The science fiction series Fringe season three finale "The Day We Died" takes place around May 20, 2026.
- Power Rangers SPD takes place in the year 2025.
