So that's the climate f****d then

If you're looking for a really hot planet, it would be hard to beat Kelt-9b.

https://www.theguardian.com/science...ts-is-so-hot-its-air-contains-vaporised-metal

The planet, called Kelt-9b, was discovered last year by an American team. It is in orbit about a star 650 light years from Earth in the constellation of Cygnus, the swan. The ultra hot planet is about 30 times closer to its host star than the Earth is to the sun — and its star is also twice as hot as the sun. As a result, temperatures on Kelt-9b reach 4,000C on the side that faces the star. This is not as hot as our Sun, which is almost 6,000C, but hotter than many stars.

Due to its proximity to the star, the planet orbits the star every 36 hours, with the same side always facing inwards. This means there is constant daytime on one side and constant night on the other, creating extreme temperature variations across the planet. The temperature of the night side is probably still about 2,000C, though, Heng suggested.

Detailed measurements of the orbit suggest the planet is gaseous, probably mostly hydrogen and possibly with a small solid core. The latest observations, published in Nature, are the first to reveal the composition of the planet’s atmosphere.

Bet the air-conditioning bill there is a killer!

How on earth does a gaseous planet survive those conditions, though? I'd have thought that the solar wind would have stripped most of the atmosphere, as it did (we surmise) for Mercury. And that's before you think about whether the gas would simply escape due to the energy it possesses, it must surely be a plasma?
 
Dowser,

It's sadder than sad. The Great Barrier Reef has been around longer than humans in any form have been on Earth.

Joe
 
The Great Barrier Reef has been dying since the 1970s. Periodically it gets reported in the Australian Press, someone does a feature on Channel 9 or the ABC, then it gets forgotten again.

The human race couldn't give a f**k, as long as there is a resort with a good beach bar closeby, and decent water skiing.
 
This is fundamentally different — the mass bleaching in 2016 and 2017 because of warming oceans is a catastrophe for the reef system in every sense of the word.

Joe
 
Yes, I think 50% of reef has bleached since 2016 - I haven’t checked, but I assume they is no way to save it now. What was Ben Elton’s first story book?
 
This is a good interactive feature for anyone who's interested.

An unprecedented succession of coral bleaching events has left reefs around the world in a catatonic state. Almost half the Great Barrier Reef has been reduced to a coral graveyard, with coral cover at its lowest point since monitoring began.

The unusual and devastating thing this time is two back-to-back coral bleaching events.

Joe
 
No, it's not fundamentally different, it's the same process. Warming oceans were always the problem, we just chose to ignore it in the search for economic bliss.

Yuk to the interactive format. :eek: But there's a three-episode video from ABC on the subject (see below).

And there was also this lengthy piece on a similar subject recently https://www.themonthly.com.au/issue/2018/august/1533045600/james-bradley/end-oceans "In June this year, scientists from the University of Tasmania and the University of Technology Sydney published research showing that over the past decade the biomass of large fish in Australian waters has declined by more than a third."

 
Thanks, man.

I'll have a look at the documentary tonight.

it is possible to create custom tags for things like this. one for twitter would be handy, as well, given the current president-child of the USA.

P.S. This slightly different one doesn't embed either, but it plays automatically.

joe.

those are impressive representations and graphics work.
