atmospheric sounds start to develop when the house becomes
more «alive», with things moving, deliberate glitches appearing and lighting

Seeing this as a baseline, positive CO2 feedback from temperature
changes, or a running out of capacity for greater uptake from CO2 accumulation, would be seen as adding

atmospheric accumulation of CO2 greater than anthropogenic emissions (first, as a rate, and later, cummulative
change).

But the newly obtained documents show that Dr. Carlin's highly skeptical views on global warming, which have been known for
more than a decade within the small unit where he works, have been repeatedly challenged by scientists inside and outside the E.P.A.; that he holds a doctorate in economics, not in
atmospheric science or climatology; that he has never been assigned to work on climate
change; and that his comments on the endangerment finding were a product of rushed and at times shoddy scholarship, as he acknowledged Thursday in an interview.
The argument is then that the reason trends outside the Atlantic are weak is that they aren't being influenced by the AMO; the other explanation is that the other regions are already over the threshold, so that the Atlantic basin is

change of, say, +10 ppm (0.00001) in the
atmospheric CO2 concentration?

That one was little - noticed by the world's media, but now its findings may receive

The first is climate inertia — on very many levels, from fossil lock - in emissions (decades), ocean -
atmospheric temperature inertia (yet
more decades), Earth system temperature inertia (centuries to millennia) to ecological climate impact inertia (impacts becoming worse over time under a constant stress)-- all this to illustrate anthropogenic climate
change, although already manifesting itself, is still very much an escalating problem for the future.
One is that climate
change is altering the pattern of
atmospheric circulation, causing
more ozone to be carried away from the tropics.
Again (don't tell Santer) it's the Sun stupid:
changes in UV light has a direct influence on the stratosphere due to
more Ozone and this results in greater warming of the upper stratosphere and swirling, wind - driving, convective
atmospheric vortices that are known as weather.
The answer is: almost nothing for
more than 10 years... The lack of any statistically significant warming for over a decade has made it
more difficult for the United Nations Intergovernmental Panel on Climate
Change (IPCC) and its supporters to demonize the
atmospheric gas CO2 which is released when fossil fuels are burned.»
