The Arctic Ocean is seeing a speedy amount of icing red this time of year , but NASA scientist are n’t too alarmed .
“ A decennium ago , this twelvemonth ’s sea chicken feed extent would have define a new record low and by a fair amount , ” said Walt Meier , a ocean icing scientist at NASA ’s Goddard Space Flight Center . “ Now , we ’re kind of used to these down levels of ocean ice – it ’s the new normal . ”
So now that scientists oppose to spheric thawing with an almost charming amount of indifference ( the Methedrine caps are melting , this is n’t news ) , it ’s about finding different mode to measure the amount of ice-skating rink near our celestial pole . When you ’ve take over something is a reality , the next thing you require to do is figure out how to observe it .
so as to value deoxyephedrine thickness , most researchers use vessels or submarines , but scientists are working to figure out how to mensurate it from compass . It seems like satellites can be used to value anything on Earth , but the salt in the sea water tends to intervene with radiolocation .
According toa statement by NASA , a satellite call Ice , Cloud and Land Elevation Satellite-2 ( ICESat-2 ) will use laser and “ a very precise detection instrument ” by timing how long it takes for the laser to attain the Earth and recoil back to the planet . It ’s slat for launching in 2018 . However , this only enshroud some of what needs to be mensurate . scientist will have to reckon above - urine tallness versus below , along with other factors .
We ’re not going to hit a new criminal record this year when it make out to low sea ice levels , which is probably a good affair . This March , NASA enter a phonograph record low maximum extent for ice in the Arctic and it lost a mess more ice throughout May . It slow down down in June , but picked back up again in August , where the sun is at its crest .
This of track has been correlate to an median rise in temperature across the Earth ’s Earth’s surface . Consideringthat last monthwas the live month since we began keeping records , I ’m more surprised that the glass has n’t mellow out even more ( in the video above , you may see how the ice caps seem to shrivel up around mid - July ) . Andevery year , we just keep demolish those phonograph record . frankly , if I was studying global temperatures , I ’d credibly be nonchalant about it too by now .
