A main control on atmospheric CO2 appears to be the ocean surface temperature, and remains a possibility that a significant part of the overall increase of atmospheric CO2 since at least 1958 (start of Mauna Loa observations) simply relflects
the gradual warming of the oceans as a result of the prolonged period of high solar activity since 1920 (Solanki et al., 2004).
«Some researchers believe that if people immediately halted emissions of greenhouse gases,
gradual warming of the oceans would ultimately contribute to an additional warming of the atmosphere of between 0.9 ºF and 2.7 ºF, or 0.5 ºC and 1.5 ºC (Mahlman, 2001, p. 8).»
Not exact matches
Over the 5 long term, this
warming conforms to a complex trend that can be simplified as a monotonic curve, but the actual pathway is steplike... this rules out
gradual warming, either in situ in the atmosphere or as
gradual release from the
ocean, in favour
of a more abrupt process
of storage and release.
But this
gradual warming of the Arctic
ocean did not begin just a decade ago, but has been gradually occuring for many decades.
It seems this happened 55 million years ago, when
gradual warming of the atmosphere penetrated to the
ocean depths and unlocked the methane, which caused a much greater
warming that resulted in the extinction
of millions
of species.
Climate change will affect fisheries and aquaculture through
gradual warming,
ocean acidification and through changes in the frequency, intensity and location
of extreme events.
Global
warming refers to the
gradual increase in the temperature
of the Earth's surface, atmosphere and
oceans as a result
of greenhouse gases.
In the models
of greenhouse
warming, the
gradual dilution
of northern
oceans by rain eventually slows the flushing until it is about 25 percent below normal.
The main thing to learn is: (a) the
oceans are gradually heating up, along with a hotter atmosphere but (b) on top
of that
gradual warming we now find extreme
ocean heating events.
As the term implies, global
warming is the
gradual increase in the average temperature
of the atmosphere and
ocean due to human influences.
Global
warming, the
gradual heating
of Earth's surface,
oceans and atmosphere, is caused by human activity, primarily the burning
of fossil fuels that pump carbon dioxide (CO2), methane and other greenhouse gases into the atmosphere.
This value
of 375 CO2 - e is the actual forcing that is currently acting to
warm the
oceans, melt ice, and cause
gradual upwards changes in average air temperature.
«Recent research, however, suggests that there is a possibility that this
gradual global
warming could lead to a relatively abrupt slowing
of the
ocean's thermohaline conveyor, which could lead to harsher winter weather conditions, sharply reduced soil moisture, and more intense winds in certain regions that currently provide a significant fraction
of the world's food production.
Plus Antarctic models are still FUBAR: The
gradual warming of the North and tropical Atlantic
Ocean is contributing to climate change in Antarctica, a team
of New York University scientists supported by the National Science Foundation has concluded.
Advocates
of the assumption that CO2 variations are a primary cause
of changes in deep
ocean heat content (i.e., those who author government - sponsored IPCC reports and activists for the anthropogenic global
warming cause) have necessarily believed that past natural variations in deep
ocean heat content are very slow and
gradual.
