The impacts of climate change are so overwhelming, they’re actually messing with time, according to new research. Via CNN:
Polar ice melt caused by global warming is changing the speed of Earth’s rotation and increasing the length of each day, in a trend set to accelerate over this century as humans continue to pump out planet-heating pollution, according to the study published Monday in the Proceedings of the National Academy of Sciences.
The changes are small — a matter of milliseconds a day — but in our high-tech, hyperconnected world have an important impact on computing systems we have come to rely on, including GPS.
It’s yet another sign of the huge impact humans are having on the planet. “This is a testament to the gravity of ongoing climate change,” said Surendra Adhikari, a geophysicist at NASA’s Jet Propulsion Laboratory, and a report author.
The number of hours, minutes and seconds making up each day on Earth are dictated by the speed of the Earth’s rotation, which is influenced by a complex knot of factors. These include processes in the planet’s fluid core, the ongoing impact of the melting of huge glaciers after the last ice age, as well as melting polar ice due to climate change.
