Earth's surface temperature will reach around 420 K (147 °C; 296 °F), even at the poles. [86] [103] 2.8 billion High estimate until all remaining Earth life goes extinct. [86] [103] 3–4 billion The Earth's core freezes if the inner core continues to grow in size, based on its current growth rate of 1 mm (0.039 in) in diameter per year.
This could potentially turn the Earth back into a water world, and even perhaps drowning all remaining land life. [98] The loss of the oceans could be delayed until 2 billion years in the future if the atmospheric pressure were to decline. A lower atmospheric pressure would reduce the greenhouse effect, thereby lowering the surface temperature.
Earth and the Moon will be most likely be destroyed by falling into the Sun, just before the Sun reaches the largest of its red giant phase when it will be 256 times larger than it is now. Before the final collision, the Moon possibly spirals below Earth's Roche limit, breaking into a ring of debris, most of which falls to Earth's surface. [216 ...
At least until you pass through the center. We can imagine what it's like to fall through the Earth, but you still don't want to fall into a black hole. The good news?
This week, see the Boeing Starliner spacecraft return to Earth without its astronauts, solve a shark murder mystery, watch a mushroom control a robot, and more.
As of February 5, 2025, the clock counts down to July 21, 2029 at 11:00 PM. The clock is hosted by Human Impact Lab, itself part of Concordia University . [ 3 ] [ 4 ] Organisations supporting the climate clock include Concordia University, the David Suzuki Foundation , Future Earth , and the Climate Reality Project.
Earth will soon have a second moon, but it will be nothing like the one we're accustomed to seeing in the night sky. The new "mini-moon" will be asteroid 2024 PT5, a space rock discovered earlier ...
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]
