Fish to shrink as global warming leaves them gasping for oxygen

Sep 30, 2012 Full story: Reuters 13

Fish are likely to get smaller on average by 2050 because global warming will cut the amount of oxygen in the oceans in a shift that may also mean dwindling catches, according to a study on Sunday.

That and the threat of hydrogen sulfide reaching the surface as the 'oxygenated layer' shrinks. This could wipe out LAND life. Though not in the next decade at least.

"Atmospheric photochemical modeling indicates that resulting fluxes of H2S to the atmosphere (>2000 times the small modern flux from volcanoes) would likely have led to toxic levels of H2S in the atmosphere. Moreover, the ozone shield would have been destroyed, and methane levels would have risen to >100 ppm. We thus propose (1) chemocline upward excursion as a kill mechanism during the end-Permian, Late Devonian, and Cenomanian–Turonian extinctions, and (2) persistently high atmospheric H2S levels as a factor that impeded evolution of eukaryotic life on land during the Proterozoic."

Fuuny thing is when I started to look up the rest of the story of where Dr Chung really worked. It turns out he works for the CRU and based all this on a model he wrote. Of course he will not show his model to the rest of the world and his is the only model that shows this. The rest of the models are showing an increase of O2 in the water from the increase in flaoting ocean plant life responding to the warmer waters and increase growing areas as the result of a rising sea.

Warmer oceans support far less life. It's for good reason that whales feed at the poles and breed in the predator-and-parasite-free tropics. Look where the plankton and krill is:

All that picture showed was what ocean temperatures are and not what sea life is where or anything else related to sea life.

Also when you talk about where whales breed, what makes you think that the tropics are predator free. Funny thing is far more sharks are found in the tropics because the warmer waters support more sources of food including tuna and swordfish.

And yes, less look at where plankton and the coral that feeds on it is located.

Incredible you are a disgrace to the education system. You fail miserably in that department. Your teachers should be banned from any school system.

What perfect timing. A local university asked if I would be interested in teaching a few classes in computer science.

Also, noticed that the post you are whining about included links to point out such things as the large fish who live in warmer waters like tuna, swordfish, and the great white shark.

Bigger fish due to climate change: tuna industry

Updated Fri Jul 11, 2008 11:27am AEST
The tuna industry says climate change is bringing benefits.

The chief executive of the Australian Southern Bluefin Tuna Association, Brian Jeffriess, says Port Lincoln crews in South Australia are reporting an excellent quality and size catch.

He says it can be partly attributed to the effects of climate change on the waters of the Great Australian Bight.

"There's no doubt climate change will bring benefits to the Great Australian Bight ecology in the sense that there's more upwellings therefore more small pelagics as we call them - sardines, mackerel, red bait, other fish - and that will bring tuna so there may be even winners from climate change," he said.

"This year some of the oceanographers are saying they've never seen south-easterly winds in a sustained strong way now that creates a lot of upwellings in the water - that brings nutrients to the surface.

"There's a feed chain which feeds on those - the tuna is virtually the last part of that food chain and benefits from improvements in the other parts of the food chain."

Do let all know the name of the University so we can forward your great work here before you ruin the innocent children.

Hay dirtling there is a great oppertunity for you to partner up with the Less than a Box of Rocks at that University. It can clean up the trash and you the crap.Anyway we see your doing the cut and paste useless babble thing again. Have you seen your care giver today?
