The 2020s (pronounced "twenty-twenties" or "two thousand (and) twenties", shortened to "the '20s") is the upcoming decade in the Gregorian calendar that will begin on January 1, 2020, and will end on December 31, 2029.
Notable predictions and known eventsEdit
- The interaction of the three main decadal solar cycles suggests an upcoming reduction in solar activity, with a low-energy period centered on 2020. As suggested by John Maddox of Nature, this might mitigate the global warming trend (at least temporarily) in the 2020s.
- 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 reach its peak.
- NASA plans to send a human mission to the Moon via the Artemis program.
- Voyager 1 and Voyager 2 are expected to stop transmitting back to Earth in the 2020s.
- By the mid-2020s, the world population is projected to surpass 8 billion people, half a billion more than the 2017 population of 7.5 billion.
- By 2022, India is projected to surpass China as the most populated country on Earth.
- The Mars-Grunt sample return mission is proposed to launch in the mid-2020s.

Assuming that the AMO continues with a 70-year periodicity, the peak of the next cycle would be expected in 2020 (70 years after the previous 1950 peak).
