one of the long-standing problems we ve had is separating out the effects of weather from climate. and that s been a source of confusion and misinformation, actuallier for many decades through my career. and people have said what we re seeing is just part of the weather cycle. and we haven t had a satellite in space to monitor the polar ice sheets that can really do a good job of distinguishing between changes in snow and ice. and that s really weather and climate. so we re testing a new radar system that the european space agency will fly in space towards the end of this decade that will do that job for us for the first time. so it s really important that we can be sure about the changes that we see and when we tell people that they re related to climate, they can have confidence in that. yeah. very god point there. and of course this latest report highlights the four key climate indicators that broke records in 2021. greenhouse gas emissions, rising sea levels, warmer and more
we just don t know how much. the scientists say that the level of the oceans is bound to go up, almost whatever we do, maybe by half a metre or so by the end of the century, if emissions are brought under control, but maybe by a metre if they aren t. and of course, that would be devastating for millions of people living on coastlines around the world. but they also can t rule out a much larger rise, approaching two metres. it all depends whether the polar ice sheets start collapsing. the great ice sheets are already adding to the level of the sea, but this process may suddenly accelerate. scientists aren t sure, but the implications would be disastrous. india is now in the grip of flooding. higher seas would make it worse. the science has never been so clear that we can head off the worst of climate change, but not all of it,
Study says the speed of ice loss is increasing, Earth losing 1.3 trillion tonnes a year
Synopsis
The researchers noted that ice melt across the globe raises sea levels, increases the risk of flooding to coastal communities, and threatens to wipe out natural habitats which the wildlife depends on.

LONDON: Earth has lost 28 trillion tonnes of ice between 1994 and 2017, according to a study which reveals that the rate at which ice is disappearing across the planet is speeding up. The research, published on Monday in The Cryosphere journal, found that the rate of ice loss from the Earth has increased markedly within the past three decades, from 0.8 trillion tonnes per year in the 1990s to 1.3 trillion tonnes per year by 2017.
to have you here. thank you so much. there is a startling new report in the journal science that claims the polar ice sheets are melting at record rates. up to five times faster than in the 90s. look at this video. it s fascinating. time lapse video from greenland. the report says that country and antarctica are losing 344 billion metric tons of ice a year equal to the weight of more than a million empire state buildings. scientists say these findings are important because the melting is causing sea levels to rise, and that makes coastal storms, say superstorm sandy, worse because of the massive flooding that s caused.
