Oceans warming at the rate as if 5 Hiroshima bombs were dropped in every second
- Tepix 7y agoBut are they being detonated? /s
- rdxm 7y agoI absolutely hate clickbait titles like this. Moreover, in the case of a serious topic like climate change catastrophising every g-damn piece of information doesn't make it easier to get people to engage in the topic.
- yostrovs 7y agoDoes Nagasaki not matter? It rarely seems to matter these days as it's almost never mentioned.
- ollie87 7y agoThat's your comment after reading this? Pretty weird.
- dvh 7y agoWho was second man on the Moon? Who was second on Mount Everest?
- shantly 7y agoAldrin gets mentioned in the same breath as Armstrong often enough I bet quite a few people could pull that one out. You'd lose a bunch with "who's the guy who stayed in orbit?" and almost everyone with "name any Apollo 12 astronaut" or even the more-generous "name any Apollo astronaut who at least reached Lunar orbit and wasn't on 11 or 13". Most of the people who get that second one would probably just luckily guess Alan Shepard without actually knowing for sure he was on an Apollo mission, just the first famous space-program-guy who came to mind who wasn't Armstrong or Aldrin (and in fact the Apollo part of the career is not why they know his name).
- Angostura 7y agoIn the UK, areas are often presented in terms of football pitches, volumes in terms of Olympic swimming pools. That does not mean that rugby or waterpolo do not matter.
- 2T1Qka0rEiPr 7y agoI know the intended purpose of this sentence is that it shocks, but I'm not sure I'm in a position to evaluate "5 Hiroshima bombs" any more clearly than if it were presented as a metric (joules in this case) I seldom use. Would it be wrong to call it click-baity? "2019 - Yet Another Year of Record-Setting Ocean Warming" would be equally alarming to me, but I'd also understand what it means.
- rat9988 7y agoNeither the hiroshima bombs nor the joules would be match telling for me. Calories might give me a small idea for non salted water at best. I'm not used to this scale and magnitude.
- kingkawn 7y agoIn this era it is important that messages with political intent not be presented as one argument, but be presented in every way possible. In regards to climate change specifically; we need the articles with reasonable headlines, we need the articles with headlines dripping in hyperbole, we need the headlines saying it’s catastrophic, we need the headlines saying it’s sensible and the right calm choice to make these changes now. Everyone’s participation is needed to deal with this threat, and so every possible approach and argument can be deployed in the effort without diminishing any other.
- thaumasiotes 7y ago> Everyone’s participation is needed to deal with this threat, and so every possible approach and argument can be deployed in the effort without diminishing any other. Well, unless some of the people notice the messages intended for the other people. "It's important to tell everyone exactly the lies that will make them do what I want" is a really uncompelling pitch.
- polotics 7y agoCan you clarify why you mention the word "Lie" ?

- aequitas 7y agoIs someone trying to exhaust a ZFS storage pool?
- BTinfinity 7y ago"Humour is allowed". A rule followed at your own risk, it seems
- sampo 7y agoEyeballing the graph, oceans have been warming at the same linear rate for 30 years, since 1990.
- 11235813213455 7y agoWhat's the energy / pollution released by a supertanker or container ship during one shipping? Might be close to one Hiroshima bomb
- madaxe_again 7y agoGiven an engine running at 50,000kW (roughly cruising power for a post-Panamax vessel) for a week (a very rough “average” shipping), you’d be looking at ~3x10^13 J. The Hiroshima bomb was 6.3x10^13 J. So, an average shipping is about half a Bomb in direct heat - add in the emissions from burning the diesel/bunker oil, and their warming effect, and you’re probably at a full Bomb per shipping.
- Angostura 7y agoI did a very quick and dirty back of the envelope guesstimate independently and came up with a vessel producing about 1/6th of a bomb a day. So around about the same as yours.
- jononor 7y agoWith 1.83 billion metric tons shipped annually (2017), and assuming all ships are loaded full with 120'000 metric tons (post-Panamax limit), there are around 15'000 such shipments yearly. Which begs the question, why isn't the impact higher?

- Const-me 7y agoEarth receives 1.73E+17 watts from the sun, an equivalent of 25000 Hiroshima bombs dropped every second.
- dr_dshiv 7y agoThat's so helpful! How many bombs are then reflected away? We can then evaluate global warming relatively against the difference.
