Default Blue Planet II Comes To iPlayer In 4K HDR

Blue Planet had a few lies in it.

Indeed, such as the plastic ducks they filmed that looked fresh from
the factory, and not subject to 20 years of exposure to sea water and
sun which bleaches them. They admitted it was faked.

To quote Matt Ridley:

So it was naughty of Blue Planet II, in showing a sequence in which a
mother and calf walrus desperately try to find a bit of ice big enough
to bear their weight but not already occupied by other walruses, to
imply that this was evidence of climate change threatening a species
with extinction. Most of the ice in the Arctic Ocean disappears each
summer and reappears each winter. Walruses have hauled out on shore, or
on what’s left of the ice at that season, forever. The main thing that
has changed is that there are now more walruses, and more polar bears
feasting on them, throughout the Arctic.

So the climate change obsession is still sometimes getting in the way of
telling the truth. The most dishonest sequence in the series was when
Attenborough watched shells dissolving in a tank of acid, to a
soundtrack of fizzing noises, and was told by Professor Chris Langdon
that although this was “more dramatic than what’s happening in the
oceans”, nonetheless “the shells and the reefs are really truly dissolving”.

This is highly misleading in several different ways. Was it carbonic
acid, or another acid? The reduction in alkalinity will get nowhere near
neutral, let alone actual acidity, even by the end of the 22nd century,
so “dissolving” is false, let alone happening now. The changes in ocean
pH expected even by the end of this century are minuscule compared with
what was shown in that tank, and by comparison with the daily and
seasonal changes that an average reef experiences. (Coral bleaching, a
different issue, is more serious, but more temporary.)

Note Ridley's use of "imply" that it was evidence of climate change. The
programme didn't say it was evidence of climate change; that is Ridley's
interpolation.

And a letter in today's Times has a letter from Professor Schmidt
(behind a paywall) which points out that Ridley "is wrong to think that
ocean acidification is not a problem... Evidence is strong that the rate
of change is unprecedented in the history of most organisms."

Here we go again, more timewasting **** from
I-like-banging-my-head-against-a-brick-wall Bill:

https://en.wikipedia.org/wiki/Matt_Ridley

"Ridley was chairman of the UK bank Northern Rock from 2004 to 2007,
during which period Northern Rock experienced the first run on a British
bank in 150 years. Ridley chose to resign, and the bank was bailed out
by the UK government leading to the nationalisation of Northern Rock."

So WTF does this failed businessman know about Climate Change? Well, at
least he does have 1st in Zoology, which is at least a science subject,
so that's an improvement on Bill's usual sources, but it's still not
Climate Change, or at least Planetary Science, or Atmospheric Science,
is it?

Isn't it just - but not quite in the manner he's claiming!

And so the clown show goes on ...

I'm a bit worries about "sea ice" at the South Pole. I thought there was
solid ground under all that ice.

There is, but there is also sea ice.

I do hope it does come as it will be the first proper 4K programme that
I will watch.


The web site says that it will be available on iPlayer immediately after
the final episode on Sunday.



What I would like to do is download it with get_iplayer, save it on a
USB stick and then play it at a later date in February or March when I
have access to a 4k tv. Any chance?

Sounds like that will need someone with a 4K HDR TV to "snoop" on the
connection between the TV and iPlayer servers to see the id of the new
stream type they use, then alter get_iplayer to support a new
--tvmode=4kuhd or whatever parameter, then not mangle the HDR with
whatever processing it does with ffmpeg to the contents.

No sign of such tweaks in github ...
