The rate at which ice is disappearing across the planet is speeding up, according to new research.
[...] The figures have been published today (Monday, 25 January) by a research team which is the first to carry out a survey of global ice loss using satellite data.
The team, led by the University of Leeds, found that the rate of ice loss from the Earth has increased markedly within the past three decades, from 0.8 trillion tons per year in the 1990s to 1.3 trillion tons per year by 2017.
Ice melt across the globe raises sea levels, increases the risk of flooding to coastal communities, and threatens to wipe out natural habitats which wildlife depend on.
[...] Lead author Dr. Thomas Slater, a Research Fellow at Leeds' Centre for Polar Observation and Modelling , said: "Although every region we studied lost ice, losses from the Antarctic and Greenland ice sheets have accelerated the most.
[...] The increase in ice loss has been triggered by warming of the atmosphere and oceans, which have warmed by 0.26°C and 0.12°C per decade since the 1980, respectively. The majority of all ice loss was driven by atmospheric melting (68 %), with the remaining losses (32%) being driven by oceanic melting.
[...] Just over half (58 %) of the ice loss was from the northern hemisphere, and the remainder (42 %) was from the southern hemisphere.

Not bad, for a 14-year old boy, pretending to be all growed-up on the internet. But completely wrong, in all details.

really? I thought 14yo boys were the ones who argue by saying "nuh-huh, you're wrong" and providing no details or any information at all. Have you taken reading class yet? Seems all the scientists got all the details wrong too, since you say so.

For the supposed grown up in the room, every time I see you post you're being an insulting, instigative twat.

Correct. I'm here to get my kicks by laughing at people like you. *gasp* the guy on the receiving end of the insult thinks I'm being insulting. Yeah skippy. That's the point - to be insulting to dumb social rejects. You're my personal clown.

Indeed. Ice is less dense than water. That's why it floats.

He has a very slight point. If you melt freshwater ice and spread it evenly over the saltwater, the level will be very slightly higher than when the ice was floating. The volume of the freshwater is more than the volume of saltwater that the weight of ice would displace.
With mixing the difference is small enough to be irrelevant.
