The 2020s, also known as the "twenty twenties", is the upcoming decade that will begin on January 1, 2020, and will end on December 31, 2029.
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. As suggested by John Maddox of Nature, this might mitigate the global warming (at least temporarily) in the 2010s and 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 peak during this decade.
- Each of ESA (Europe), CNSA (China), FKA (Russia), and ISRO (India) plan to send a manned mission to the Moon in this decade.
- According to a report released by the National Intelligence Council, the United States will experience the relative decline of its economic and military power, driven both by the rise of new behemoths such as China, India and the EU and by domestic constraints on its global leadership.
- Voyager 2 is expected to stop transmitting back to Earth in the 2020s.
- 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.
- Intel predicts the performance of supercomputers to reach zettaflops scale by 2029.
- 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, the world population is projected to surpass 8 billion people, half a billion more than 2020, representing a slowdown in growth from the 2010s, which are expected to increase the population by 700 million.
- The Mars-Grunt sample return mission is proposed to launch in the mid-2020s.
- China's coal production will peak and then rapidly decline in the year 2027.

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).
