Recent studies have found increasing greenhouse gas concentrations to be the major cause for much of global ocean temperature warming, yet it is unclear how they have contributed to the observed IPWP region changes along
with natural variability in the climate.
I'd just like to make sure I understood your post correctly: the common answer to the «contrarian talking point» that much of the observed recent climate change could just be caused
by natural variability in the climate system is that this would imply, broadly speaking, heat being moved from the oceans to the atmosphere — whereas we observe the opposite, oceans storing heat.
«The probability of all those things happening out of a convergence
of natural variability in the climate system — it strikes me as a lower probability than recognizing that we stacked the deck in favor of [these conditions.]»
Researchers start the model simulations using the current state of the climate system, in particular ocean conditions, «and by doing that, we can potentially predict any kind of
natural variability in the climate system» as well as the background warming signal, Smith said.
They concluded that the heavy rains in Europe last year were likely due to
natural variability in the climate system rather than climate change.
The crucial question now is whether the temperature changes in the Pacific reflect
a natural variability in the climate that might reset itself in a few years or whether the shift to weaker long rains is a permanent result of human - induced climate change.
However, researchers have yet to pin down the exact contribution of greenhouse gas emissions and
natural variability in the climate.
«The CCR - II report correctly explains that most of the reports on global warming and its impacts on sea - level rise, ice melts, glacial retreats, impact on crop production, extreme weather events, rainfall changes, etc. have not properly considered factors such as physical impacts of human activities,
natural variability in climate, lopsided models used in the prediction of production estimates, etc..
«From what I can tell, the list was compiled mostly from reviewed scientific articles in which authors proposed or identified various sources of
natural variability in climate; in my case solar irradiance and cosmic ray flux.
This natural variability in the climate makes it harder to determine a single precise pre-industrial baseline.
I'm very much an AGW skeptic, so I don't discount the idea that there are
natural variabilities in the climate system that greatly outweigh human influences.
By Simon of Australian Climate Madness The role of
natural variability in climate must be squashed at all costs.
When you look more closely at the annual temperature record, you can see how the long - term warming trend — for the most part caused by human activities — is manifesting itself along with shorter - term
natural variability in the climate system.
