Analysis of melting of glaciers in Antarctica in last 50 years and its prediction in coming days.
Answers
Answer:
It’s not exactly news that Greenland and Antarcticaare shedding ice at record rates.
But in 2016, an eyebrow-raising idea ricocheted through the scientific community: It was possible, the authors said, that a warmer planet could push the towering ice cliffs at the fringes of the Antarctic ice sheet to essentially self-destruct, collapsing like a set of dominoes.
What was extra shocking was just how fast the ice could retreat under this runaway scenario, leading to about three feet of sea level rise fed from Antarctica alone by 2100—much faster than previous estimates, which generally proposed increases of only a few centimeters by the end of the century.
Answer:
- New predictions by the journal Climate Dynamics have found that sea levels may rise far sooner than expected.
- With these rising levels, we can expect devastating storms and global temperatures rising even faster because there’s less ice to reflect heat.
- It's suggested that experts have been underestimating how bad the impacts of climate change might be, not accounting for extreme weather events.
As rising global temperatures continue to melt the ice in Antarctica, scientists predict that we’ll face serious problems in the coming decades — from rising sea levels to devastating storms to temperatures rising even faster because there’s less ice to reflect heat.
Now, it turns out all those problems could be even worse than scientists predicted, according to research published in the journal Climate Dynamics. Existing models tended to predict ice melt based on average conditions over time, but accounting for fluctuating extremes paints a far more dire picture.
