Melting glaciers, rising sea level slow down Earth's rotation - Technology & Science - CBC NewsRising global temperatures and melting glaciers are not only affecting our weather systems, they are also causing days to become longer.Researchers have discovered that rising sea levels, as a result of global climate change, are causing a slight slowing of the Earth's rotation.Over the past century, these changes have caused the North Pole to 'wander' at a rate of a centimetre a year and this has added a thousandth of a second to the length of our days.
With human-caused climate change, we puny creatures are having some powerful effects on our entire planet, including one you might not imagine was possible — making it spin more slowly.Arctic Temperatures Warmest On Record | Al Jazeera America
The melting of glaciers near the Earth's poles and the resulting rise in sea level is slowing down the Earth's rotation and making each day a little longer, a new study confirms.
Scientists had predicted it would happen, but to their puzzlement, they couldn't measure much of an effect.Glaciers contain a huge amount of mass near the poles, close to the Earth's axis of rotation, which runs from pole to pole. When glaciers melt, the meltwater ends up in the oceans, which have most of their volume near the equator, farther away from the Earth's axis.
Arctic temperatures in 2015 were the warmest on record, according to a report published on Tuesday that furthered concerns about the negative effects of melting sea ice.
Temperatures in the Arctic were more than 2 degrees Fahrenheit warmer than average in 2015, according to the National Oceanic and Atmospheric Administration (NOAA) report. Some areas of the Arctic experienced temperatures more than 5 degrees warmer than average.
“The Arctic is warming twice as fast as other parts of the planet,” NOAA Chief Scientist Rick Spinrad warned during a press conference on Tuesday.
The higher-than-normal temperatures contributed to less sea ice in the Arctic, according to the report, compiled by some 70 authors from 11 countries.
