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 on 2020.[6] As suggested by John Maddox of Nature, this might mitigate the global warming (at least temporarily) in the 2010s and 2020s.[7]
- 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.[8][9]
- The ESA (Europe),[10] CNSA (China),[11] FKA (Russia),[12] and ISRO (India)[13] each plan to send a manned mission to the Moon.
- According to a 2008 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.[14]
- Voyager 2 is expected to stop transmitting back to Earth in the 2020s.[15]
- In 2008, futurist Ray Kurzweil put 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.[16]
- In 2008, Intel predicted that the performance of supercomputers will reach zettaflops scale by 2029.[17]
- 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 2020s, the world population is projected to surpass 8 billion people, half a billion more than 2020, representing a slowdown in growth from the decade of the 2010s, which is expected to see an increase in the world population by 700 million.[18]
- By the mid-2020s, India is projected to surpass China as the most populous country.
- 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 (prediction in 2011).[19]
