Oceans Could Soon Not Have Enough Oxygen To Support Marine Life (iflscience.com)
An anonymous reader writes: As the climate continues to change in response to the increasing amount of carbon humans pump into the atmosphere, the oceans are being particularly hard hit from melting Arctic sea ice, acidification, and warming surface temperatures. Yet those are not the only difficulties that marine life has to deal with, as a new study reports that the oceans are also losing oxygen. As the majority of marine life relies on the oxygen dissolved in the oceans, it is worrying that noticeable differences have been observed in the gas concentrations in the world's waters. The reduction in oxygen will have profound effects on ocean biodiversity, though as the study published in Global Biogeochemical Cycles shows, not all regions will be affected in the same way or over the same period of time."Loss of oxygen in the ocean is one of the serious side effects of a warming atmosphere, and a major threat to marine life," said lead author Matthew Long of the National Center for Atmospheric Research. "Since oxygen concentrations in the ocean naturally vary depending on variations in winds and temperature at the surface, it's been challenging to attribute any deoxygenation to climate change. This new study tells us when we can expect the impact from climate change to overwhelm the natural variability."
They were wrong about the ice caps melting,
The arctic ice cap is melting much faster than predicted: http://nsidc.org/arcticseaicen...
Get Billy Mays to use his stuff, it'll fix it. You may also get your clothes cleaned at the same time.
Harrison's Postulate - "For every action there is an equal and opposite criticism"
Look at the paper. It doesn't say that oxygen is decreasing to dangerous levels. It says that computers think that by 2030 it might be possible to measure a certain decrease in oxygen in certain places. The change is too small to measure at present, if that change is happening.
Simple fact: Most of the oxygen you breath comes from the ocean.

odd that you missed the point even though you specifically stated it:water holds less dissolved oxygen as it gets warmer.
the ocean is getting warmer. O2 content is measurably going down, even without the effects if El Nino. phytoplankton oxygen production is completely irrelevant to that discussion.
and yes the ocean is currently alkaline, but that doesn't mean it's not acidifying. acidifying != acidic. to be acidic pH needs to be below 7, but to be acidifying it merely needs to be moving from a higher pH to a lower pH, which it is measurably doing.
your post is meaningless deflection, and certainly not insightful.

Climate deniers are using the same tactics as the tobacco industry. The tobacco industry can still claim that tobacco does not cause cancer as many lifetime smokers never get cancer. So they can easily use the false logic that if tobacco causes cancer then all smokers would get cancer. Yes, stopping the ruin of our planet and keeping people alive will be somewhat painful and it will tend to smack us all in the wallet. But how many have considered what kind of living hell will fall upon them if we do not fight tooth and nail to restore our environment. And the first, and most vital step is to limit human reproduction. Pollution is a consequence of human activity. The simple truth is that lower population reduces human activities. With smaller populations we need less industry, less agriculture, less mining, less transportation and less of just about everything. And of all things, advanced technology requires a lot less human workers as well as far fewer people in our military. Yet we are so locked into our political foolishness that no politician dares even mentioning mandatory birth controls.
These are based on predictive computer models, not actual measurements. As the abstract says, "Anthropogenically forced trends in oceanic dissolved oxygen are evaluated in Earth system models..." then it goes on to portend dire effects in the 2030-2040: "We find that the forced signal should already be evident in the southern Indian Ocean and parts of the eastern tropical Pacific and Atlantic basins; widespread detection of forced deoxygenation is possible by 2030–2040."
As with many other alarmist reports this is based exclusively on computer models and suggests that the "forced signal should be evident" in 15-25 years. But there are no actual measurements backing the alarmist agenda. A GIGO check seems to be in order before new government programs are initiated.
mi is still arguing like a lawyer. A year or so ago I gave him a link to an article that compared temperature and sea level rise to model projections and showed the models were mostly right on temperature and lagging on sea level rise. Here's a different one that does the same comparison of observations in 2007 to the projections from the IPCC 2001 (AR3) report which started its projections in 1990. But instead of taking in the information mi will reject it because it's not in his cherished format. If mi had any gumption he'd look up the projections from the AR3 report and the observations from 2007 to have his cherished 2 sources and see if what the paper said is true. Instead he's unwilling to meet anyone halfway and wants it all handed to him on a silver platter. Like I said, he argues like a lawyer.
