Early explorer logbooks reveal Antarctic sea ice has barely changed in 100 years

Logbooks from the likes of Captain Robert Scott and Sir Ernest Shackleton - key figures in the 'Heroic Age' of Antarctic exploration - have revealed that sea ice levels in Antarctica have barely changed over the past century, despite global temperatures hitting record highs year after year.

That finding might seem counterintuitive, especially given that sea ice in the Arctic has never been so depleted. But it might actually help us explain one of the biggest mysteries surrounding climate change: how Antarctica appears to be thriving - and sometimes even expanding - despite all odds.

"The missions of Scott and Shackleton are remembered in history as heroic failures, yet the data collected by these and other explorers could profoundly change the way we view the ebb and flow of Antarctic sea ice," says lead researcher Jonathan Day from the University of Reading in the UK.

Day and his team examined observations of sea ice recorded in the official logbooks from 11 voyages that took place between 1897 and 1917, including three missions led by Captain Scott, two by Shackleton, and sea-ice records from French, German, and Belgian explorers.

These logbooks include observations of many environmental and meteorological phenomena, recorded several times a day throughout each mission by the explorers and their crew.

Many of the logbooks had been recently digitised as part of the International Comprehensive Ocean-Atmosphere Data Set initiative, but others were digitised especially for this study, and the information within was collated into a dataset of 191 observations of sea ice positions spanning two decades.

These observations were then compared to satellite data from 1989 to 2014, and other than the sea ice edge in the Weddell Sea declining by about 14 percent over the past century, the team found that ice conditions during the golden age of exploration were surprisingly similar to those in Antarctica today.

The Medieval Warm Period (MWP), Medieval Climate Optimum, or Medieval Climatic Anomaly was a time of warm climate in the North Atlantic region that may also have been related to other climate events around the world during that time, including China[1] and other areas,[2][3] lasting from about 950 to 1250.

Greenland was settled by Vikings (of Norwegian origin) more than a thousand years ago, who had previously settled Iceland to escape persecution from the King of Norway and his central government.

Medieval Warm Period - Wikipedia

I heard they got there by gas guzzling SUV longships they stole from Charlemagne / Holy Roman Empire during the explosion of combustion engines around that time.

I mean, how else can you not contradict yourself and arrive at this obvious conclusion?

Slavery would probbaly help save the environment.

burning people to generate electricity would be a big help to the planet as well

Greenland was not green for the vikings. It was always a harsh and shitty environment.

The vikings were farming in Greenland 1200 years ago.

Even so I bet it was still a harsh and shitty environment

So is Detroit, yet life goes on.

not fair until all environments equally shitty

so goes the carbon crap imperative

i can't imagine people being ok with me taxing them to breath otherwise

i think they will tax that too

just like on my power bill there is a tax for dam to create hydroelectricity

then a tax on bill to maintain the dam

then they didn't like what the dam did to local salmon population and forced them to remove the dam

now there are all those taxes and a dam removal tax on the bill

paying for it
paying to maintain it
paying to remove it

nobody blinks an eye........all of us are happy now

except, you know, anyone paying for others dumb fucking ideas or looking at their utility bills

just another damn tax

Actually, once carbon levels start dropping, photosynthesis will start to fail and mammals will begin to suffocate. (If we don't freeze to death first)

we will tax that too

there is no problem we can't solve by generating new problems

gore and leo have to send a fleet of private jets on world tour to save us all from man bear pig
11-25-16 - 08:04 PM
im gonna tax capt tele directly

call it the tele tax
11-25-16 - 08:06 PM
how big of a pool and lake house would i be able to get with this tax?

maybe it is time 4 me to milli vanilli like stein and sanders

u know...the jews

hey now, this is the ONE TIME statists want you to believe that this isnt a tax or wealth redistribution scheme but instead, to save our planet. it's not like they have a history of taxing the shit out of people in the name of the greater good or anything.

just thank them for using your money (read: piss in your face) to fund their research (and junkets) and saving you from any wealth you might generate

clearly markets cant provide enough research employment for thousands of people to solve a problem and move humanity forward
