The

Thus, the title of the USF press release, «Frogs Getting Sick from

The
climate system appears to have had three distinct «episodes» during the 20th century (during the 1910's, 1940's,
and 1970's),
and all three marked shifts in the trend of the
global mean temperature, along with
changes in the qualitative character of ENSO
variability.
«Because the
global earth system is highly complicated, until a relationship between actual storm intensity
and tropical
climate change is clearly demonstrated, it would be premature to conclude that such a link exists or is significant (from the standpoints of either event or outcome risk) in the context of
variability.»
Starting from an old equilbrium, a
change in radiative forcing results in a radiative imbalance, which results in energy accumulation or depletion, which causes a temperature response that approahes equilibrium when the remaining imbalance approaches zero — thus the equilibrium climatic response, in the
global - time average (for a time period long enough to characterize the climatic state, including externally imposed cycles (day, year)
and internal
variability), causes an opposite
change in radiative fluxes (via Planck function)(plus convective fluxes, etc, where they occur) equal in magnitude to the sum of the (externally) imposed forcing plus any «forcings» caused by non-Planck feedbacks (in particular,
climate - dependent
changes in optical properties, + etc.).)
The United Nations Framework Convention on

We can not rule out the possibility that some of the low - frequency Pacific
variability was a forced response to variable solar intensity
and changing teleconnections to higher latitudes that are not simulated by the models, or that non-climatic processes have influenced the proxies... the paleodata - model mismatch supports the possibility that unforced, low - frequency internal
climate variability (that is difficult for models to simulate) was responsible for at least some of the
global temperature
change of the past millennium.»
There is also a natural
variability of the
climate system (about a zero reference point) that produces El Nino
and La Nina effects arising from
changes in ocean circulation patterns that can make the
global temperature increase or decrease, over
and above the
global warming due to CO2.
Tim Ball on
global warming: «The
climate is
changing all the time,
and what's going on right now is well within natural

In my earlier posting, I tried to make the distinction that
global climate change (all that is
changing in the
climate system) can be separated into: (1) the
global warming component that is driven primarily by the increase in greenhouse gases,
and (2) the natural (externally unforced)
variability of the
climate system consisting of temperature fluctuations about an equilibrium reference point, which therefore do not contribute to the long - term trend.

and Yeager (2012) examined

In 1990, two years after NASA scientist James E. Hansen issued his now famous warning about

global warming was overstated
and that natural
