Climate change means days are getting longer, scientists find

Duration of day has lengthened by a millisecond over the past 100 years as water from shrinking glaciers slows Earth's rotation and shifts position of poles

The impact of climate change may appear to be overwhelmingly negative but there is a bright spot for those who struggle to find enough time in the day: melting glaciers are causing the rotation of the Earth to slow thereby lengthening our days, new research has found.

Harvard University researchers have provided an answer to a long-held conundrum over how shrinking glaciers are affecting the rotation and axis of the Earth, calculating that the duration of a day has lengthened by a millisecond over the past 100 years.
