Not exact matches

[It is helps us to understand what natural forces are currently at work that could be causing changes... But note that some natural forces like the ones that I talked about above work over much longer timescales than the century timescale over which we are making significant changes in greenhouse gas levels.

Perhaps you might want to read that paper as well as «Climate Change and Trace Gases», available in many places, which argues for an albedo flip mechanism and (relatively) short timescales for icesheet response to forcing, based on paleo data.

[Response: the Milankovitch timescale is long and the forcing barely varies due to orbital changes over 100 years so no, they aren't included (they would be for people modelling the last glacial maximum); solar forcing is modelled by change in total solar irradiance (probably as a total number; not sure if changes at different wavelengths are included)-- William]

For weather predictions, accuracy disappears within a few weeks — but for ocean forecasts, accuracy seems to have decadal scale accuracy — and when you go to climate forcing effects, the timescale moves toward centuries, with the big uncertainties being ice sheet dynamics, changes in ocean circulation and the biosphere response.

When Rawls claims the early - mid 20th century solar changes are responsible for late - 20th response, it occurs to me, given all the different timescales in the system, most of which I don't know the values for, that I don't have a feel for what the response to a pure - solar forcing might look like (leaving energy balance questions aside — just what is the shape of the curves?)

These processes are not believed to play any significant role on the timescales (centuries to millennia) of interest in discussions of anthropogenic climate forcing and climate change.

The U.S. military seems interested in climate variations / change on timescales from seasonal to scales out to about 30 years, a period over which natural climate variability could very well swamp anthropogenically forced climate change.

Identify how anthropogenic forcing and natural atmosphere - ocean variability contribute uniquely to decadal timescale changes in the width of the tropical belt.

Third order forcings — El Nino / La Nina, volcanoes, variations in greenhouse gases — changes of up to 3Â ° -5 Â °C on shorter timescales.

In particular, anomalously high convection in ENSO and ENSO - related regional cloud changes can lead to negative feedbacks not seen with persistent forcings that operate over longer timescales on a more global basiIn particular, anomalously high convection in ENSO and ENSO - related regional cloud changes can lead to negative feedbacks not seen with persistent forcings that operate over longer timescales on a more global basiin ENSO and ENSO - related regional cloud changes can lead to negative feedbacks not seen with persistent forcings that operate over longer timescales on a more global basis.

Radiative feedbacks act the same way as radiative forcings, except that they themselves are dependent on temperature changes (the distinction depends on timescale and context; also, in some contexts the feedbacks» effects are described as radiative forcings — for example, the radiative forcing of the increase in water vapor that would occur for a given temperature increase).
