This glacier used to be closer," Fagre declares as we crest a steep section, his glasses fogged from exertion. He's only half joking. A trailside sign notes that since 1901, Sperry Glacier has shrunk from more than 800 acres (320 hectares) to 300 acres (120 hectares). "That's out of date," Fagre says, stopping to catch his breath. "It's now less than 250 acres.
Scientists point out that sea levels have risen and fallen substantially over Earth's 4.6-billion-year history. But the recent rate of global sea level rise has departed from the average rate of the past two to three thousand years and is rising more rapidly—about one-tenth of an inch a year. A continuation or acceleration of that trend has the potential to cause striking changes in the world's coastlines.
wow good job your actually doing some reaserch!
yeah me too I just got bored so I just started to read.
oh ,okay I do that a lot too
I also read that A new NASA-led study has determined that an increase in snowfall accumulation over Antarctica during the 20th century mitigated sea level rise by 0.4 inches. However, Antarctica’s additional ice mass gained from snowfall makes up for just about a third of its current ice loss.
good job dude.
1 hour later
did you find any new interesting facts? though?
yeah I also found out that Medley and Thomas found that snow accumulation increased over the 20th century by 0.04 inches per decade, and that rate more than doubled after 1979.
cool I found out that In 2018, the Arctic minimum sea ice covered an area of 4.15 million square kilometers.
