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.

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


exactly.....lol

no point in any market if it isn't a centrally planned and highly convoluted market (that benefits them above all else)

they saving us world wide right now with their good ideas and great intentions

I'll be honest. I don't know where to stand on the whole climate change issue because I don't have time to dig into the details to formulate an informed opinion.

I basically believe that climate change is real. I have no fucking clue whether its man made or not, just that the climate is changing. That shouldn't come as a surprise considering its always changed.

I just wish somebody could formulate some form of cliff notes on arguments for both sides. I got shit to do man.

cliffs:

level 1 dumb: nothing we do could ever alter our environment

level 2 dumb: OMG something is happening we have to do something

[img]http://www.evidenceunseen.com/wp-content/uploads/2013/09/Picture1.png[/img]

level 3 dumb: We should all buy a prius, some solar panels, led light bulbs, stock in Elon Musk everything and that will save us from the overpopulation and over consumption/consumerist issue

[img]https://aboveaverage.com/wp-content/uploads/2015/12/newyearsgarbagepeople-800x0-c-default.jpg[/img]

level 4 enlightenment: maybe we should consume less, live simpler lives, create less of an impact, not encourage poor people to have more kids they can't afford to feed or pay for, and let the most worthless dregs cull themselves off the planet already.

GROUP 1-3 SAY GTFO......HOW AM I SUPPOSED TO FEEL GOOD ABOUT MYSELF AND GET RICH + FATTER OFF OF DUMB IDEAS LIKE THAT?

What satellites were they using back then to measure the CO2 in the atmosphere? Togo gold dome ones?

What i don't understand in this whole discussion is, even if we are not a 100% sure if climate change is man made, the responsible thing is not to to nothing. You do something because we cannot rule out that we are the cause.

Ok, you first. Start with reducing your 'carbon footprint' by:

1. quit using power (little to no light bulbs, all of your electronics)
2. use public transit or walk everywhere
3. filter your own water
4. use candles and curtains for your home
5. grow your own food
6. plant trees as carbon sinks
7. compost your own waste
8. install solar and connect it to a community power grid to share the wealth energy
9. purchase used clothing
10. purchase carbon credits (What is a Carbon Fee and Dividend - Take Action)

that should get you started. in your own words: it's the responsible thing for you to do.

Won't make any difference with about 200 million new third worlders born each year

we are fucked unless the whole bird flu thing really kicks off
