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.

If being informed was easy, liberals wouldn't need talking points. Skip to 25 minutes in for cliffs.

Not well.


If you haven't noticed - the universe is pretty dry.

I'm waiting for someone to come out and say the reason the northern ice cap is melting and the southern isn't is because hot air rises from the bottom of the planet to the top...

thats true


and the universe is wet
thar be water everywhere

It turns out that it doesn't really matter[/URL], since ice is being added elsewhere. The arctic ice is also up since 2012, even though it was supposed to all be gone by this September according to climahoaxers. Furthermore, it really, really doesn't matter, since at one point greenland was... green and was farmed by Vikings and the world didn't end and the polar bears didn't go extinct.

Oil was suppose to run out in 2030 too right, yet they just found the biggest deposit ever in Texas.

:lol:

Keep funding those alternate energy resources though, maybe if we cover the entire country in solar panels we can power one football stadium.

technically you would only need enough solar panels to cover the state of nevada to power the entire world :shrug:

i blame global warming on science

ya but free energy with no pollution is really fucking gay
that shit is for faggots

yeehaw :fu:

So at 5,000 a KW that would only cost what, 100 trillion dollars?

The average sized solar panel system is 5,000 watts, so this brings the total cost to $15,000 (3.00/watt)
12500 for 5 KW

if you spend a lot of time building predictive models, i.e. models that have demonstrated their ability to predict the future, say hurricane forecastng, you'll start to realize the level of confidence people have in climate predictions is vastly overstated. induction, which might work in cases like newtonian physics with analytic solutions, doesn't work well in a complex system. ask someone that believes in AGW whether it will be warmer a year from now, guaranteed they cannot predict with accuracy more than 50%

No problem ... we'll just get Mexico to pay for it right after they pay for the wall...

perhaps at 1000W/M and with 100% efficiency

lucky for Edison he learned what DC power transfer entails the hard way and why this wasn't in any way feasable
