It sounds reasonable, especially since it is known that warmer water holds less
CO2 than colder water does.
Not exact matches
My research indicates that the Siberian peat moss, Arctic tundra, and methal hydrates (frozen methane at the bottom of the ocean) all have an excellent chance of melting and releasing their stored
co2.Recent methane concentration figures also hit the news last week, and methane has increased after a long time being steady.The forests of north america are drying out and are very susceptible to massive insect infestations and wildfires, and the massive die offs - 25 % of total forests, have begun.And, the most recent stories on the Amazon forecast that with the change in rainfall patterns one third of the Amazon will dry and turn to grassland, thereby creating a domino cascade effect for the rest of the Amazon.With
co2 levels risng faster now that the oceans have reached carrying capacity, the oceans having become also more acidic, and the looming threat of a North Atlanic current shutdown (note the recent terrible news on salinity upwelling levels off Greenland,) and the change in
cold water upwellings, leading to far less biomass for the fish to feed upon, all lead to the conclusion we may not have to worry about NASA completing its inventory of near earth objects greater
than 140 meters across by 2026 (Recent Benjamin Dean astronomy lecture here in San Francisco).
CO2 is more soluble in
colder than in warmer
waters; therefore, changes in surface and deep ocean temperature have the potential to alter atmospheric
CO2.
The
colder, polar
waters have an ~ 3x higher
CO2 solubility
than the warmer, equatorial
waters.
This new study has demonstrated that
cold polar surface
waters will start to become corrosive to these calcifying organisms once the atmospheric
CO2 level reaches about 600 parts per million, which is 60 % more
than the current level but which could be attained by the middle of this century.
«From my basic geochemistry education in
water chemistry,
CO2 is a strange compound as it exhibits reverse solubility, unlike most compounds, it is more soluble in
colder water than in warmer
water.»
How can the atmosphere control the climate via its
CO2 content when the oceans contain 15 times more of it and
CO2 is more soluble in
cold water than warm
water (the oceans release
CO2 to atmosphere when they warm for whatever reason).
But when you look at the very
cold regions where there is almost no
water in the atmosphere to begin with, or the desert regions, you do not in fact see any observable evidence that the air is any warmer
than it was in the past with respect to
CO2 increases.
Without GHG's like
water vapor and
CO2 the surface of the Earth would cool so effectively by IR radiation that the surface would be tens of degrees
colder than it's now (how much depends on what the albedo of the
cold earth would turn out to be).
Still others have expanded on the degree to which
CO2 is better absorbed by
cold water than warm.
gnomish says: April 8, 2012 at 8:55 pm (Edit) maybe the
co2 came out of the
cold polar
waters when it warmed rather
than from the warmer equatorial ones that were already depleted?
Except for the fact that
cold sea
water holds more
CO2 in solution
than does an equal amount at a warmer tmperature.
More
CO2 can be dissolved in
cold water than warm
water, and there are a number of carbon sequestering and releasing processes involving ocean life.
About 40 percent of the carbon enter the oceans through the
waters of the Southern Ocean, around Antarctica, because
CO2 dissolves more readily in
cold seawater
than in warmer
waters.
