Earth in a few billion years could likely resemble present Venus. One billion years from now, about 27% of the modern ocean will have been subducted into the mantle. If this process were allowed to continue uninterrupted, it would reach an equilibrium state where 65% of the present day surface reservoir would remain at the surface. [59]

But after a long trend of slowing, the Earth’s rotation is now speeding up because of changes in its core. For the first time ever, a second will need to be taken off.
Melting ice is slowing Earth's spin and causing changes to its axis, new studies find. ... long been predictable influences on the Earth’s angular velocity. But now, rapid ice melt due to global ...
Currently, Earth is in an interglacial period, the Holocene epoch beginning 11,700 years ago; this has caused the ice sheets from the Last Glacial Period to slowly melt. The remaining glaciers, now occupying about 10% of the world's land surface, cover Greenland, Antarctica and some mountainous regions.
According to Nasa's Center for Near-Earth Object Studies, Asteroid 2024 YR4 has fallen off the Torino scale after recent observations. The impact probability dropped to 0.0017% or 1-in-59,000 odds ...
Venus-like conditions on Earth require a large long-term forcing that is unlikely to occur until the sun brightens by some tens of percents, which will take a few billion years. [7] Earth is expected to experience a runaway greenhouse effect "in about 2 billion years as solar luminosity increases". [4]
Scientists warn that the Earth is just 15 years away from experiencing a "mini ice age" — something that hasn't happened in 300 years. Researchers in the U.K. created a new model of the Sun ...
