quote:A Controversial Episode With Harrison Ford And Don Cheadle That Will Haunt You. Make. The. Time.
Yes, it's nearly an hour long. But whatever you have to clear from your schedule today to make time for this, I highly recommend you don't miss it. Why? It's getting brutally attacked by people who don't want you to see it.
Besides you get to watch Harrison Ford ...
and you may never buy a palm oil product again.
But you also see people being ignorant (and choosing to be ignorant) about what is going on because of religious beliefs ...
... instead of advocating to reduce global warming.
This is from a US National Snow and Ice Data Center (NSIDC) report released a couple days ago:
Sea ice surrounding the Antarctic continent reached its maximum extent on September 22 at 20.11 million square kilometers (7.76 million square miles). This is 1.54 million square kilometers (595,000 square miles) above the 1981 to 2010 average extent, which is nearly four standard deviations above average. Antarctic sea ice averaged 20.0 million square kilometers (7.72 million square miles) for the month of September. This new record extent follows consecutive record winter maximum extents in 2012 and 2013. The reasons for this recent rapid growth are not clear. Sea ice in Antarctica has remained at satellite-era record high daily levels for most of 2014.
quote:Global warming is worse than we thought, according to a study that claims temperature readings in the southern hemisphere have been inaccurate.
The US research suggests that we have been sucking up more than twice as much of the heat created by greenhouse gases than previously believed.
Scientists have now recommended increasing estimates of the rate of ocean warming by between 48 per cent and 152 per cent.
Ocean warming is a key marker for global warming as they can store more than 90 per cent of man-made excess heat. Warmer oceans are also connected to rising sea levels.
Lawrence Livermore National Laboratory scientists used satellite observations to uncover long-term ocean warming in the upper 2,300ft (700 metres) of Southern Hemisphere oceans, and found old data was inaccurate.
This offsets\refutes the deniers claim of a hiatus in atmospheric temperatures. The ocean takes in and stores much more heat than the atmosphere.
there seem to be three things that can cause more of this ice. One might be the addition of fresh water to the system. That seems likely if the Antarctic glaciers are melting (which they are). Depending on where the fresh water goes, that could allow the formation of sea ice. Also, if precipitation increased in the area, that would add fresh water.
Second, the area where the sea ice is forming could be colder. That seems backwards in on a warming planet, but actually, that can happen too. Antarctica is, to a larger extent than the Arctic, a semi-closed system of air and sea currents, because it is a roundish continent surrounded by sea at one end of the planet. This means that cold air might be retained over the continent rather coherently. At the North Pole, “Winter (January) temperatures … can range from about −43 °C (−45 °F) to −26 °C (−15 °F), perhaps averaging around −34 °C (−29 °F),” while at the South Pole, “In winter, the average temperature remains steady at around −58 °C (−72 °F).” (source: Google). The north pole is sea, the south pole is land, and the south pole is at a higher elevation, but those differences are partly why the south pole is colder. Anyway, with all this cold air on the Southern Continent, perhaps one only needs to have air currents change a little to move that cold air over the sea a bit more to add to the chances of freezing water and making sea ice.
Third is the possibility that the disruptive effects of storms, waves, or surface currents could change, making for a calmer environment, allowing more ice formation.
Have any of these things happened?
Yes. Yes, they have.
Added cold seems to be a factor. Added fresh water seems to be a factor. Changes in where cold air and relatively fresh water goes seems to be a factor. I don’t know about storminess and currents at the outer edge of ice formation.
The dramatic and steady increase in Antarctic Sea Ice is yet another example of the effects of climate change.
(see article for data links)
Glacier ice melts during the summer, the fresh water from this stays near the surface where it is easier to freeze. Changing climate patterns cause colder air at the south pole in the winter, extending over the surrounding ocean, which causes more freezing.
Re: People choosing to be uninformed make stupid decisions
I watched it and was educated and intrigued. The preacher who married the climate change scientist was refreshing. This documentary also highlighted global politics and how it is all tied in with climate change. The powers that be are well aware of whats coming. They choose not to let the public know, for it may well be that they are all too aware of survival of the fittest and don't want everybody to make it(fear of limited supplies?)
