Sentences with phrase «external radiative forcing»

«Warming during the past half century can not be explained without external radiative forcing Global Extremely likely (> 95 %)[1] Anthropogenic change has been detected in surface temperature with very high significance levels (less than 1 % error probability).

Given the uncertainties that exist in such kinds of preliminary studies, I believe it is more useful to point out that climate on decadal timescales may be quite different from that expected only considering external radiative forcing (as in the IPCC).

In fact, in AR4 (Table 9.4), the IPCC lists five lines of evidence supporting the conclusion that «Warming during the past half century can not be explained without external radiative forcing».

Here we show that several independent, empirically corrected satellite records exhibit large - scale patterns of cloud change between the 1980s and the 2000s that are similar to those produced by model simulations of climate with recent historical external radiative forcing.

Now take that sensitivity to external radiative forcing.

For starters, a long - term increase in the average global temperature must be caused by a global energy imbalance - an external radiative forcing.

It has been referred to as a stable time interval with «quiet» conditions in regards to low perturbation by external radiative forcing [30].

Basically they're an example of internal variability, not an external radiative forcing.

Natural cycles superimposed on a linear warming trend can be mistaken for step changes, but the underlying warming is caused by the external radiative forcing.

A linear warming trend plus natural cycles can be mistaken for a step function, but physically the global warming is caused by an external radiative forcing (i.e. human greenhouse gas emissions).

The IPCC has failed to convincingly explain the pause in terms of external radiative forcing from greenhouse gases, aerosols, solar or volcanic forcing; this leaves natural internal variability as the predominant candidate to explain the pause.

«The IPCC has failed to convincingly explain the pause in terms of external radiative forcing from greenhouse gases...» — That's because the tropospheric pause has nothing to do with GH gases, which never «pause» in their action, bit rather, the pause has everything to do with natural variability in the rate of energy flow from ocean to atmosphere.

Extremely likely: Warming during the past half century can not be explained without external radiative forcing.

External radiative forcing contributes to the skill of retrospective decadal sea ice predictions

The sensitivity of Earth's climate to an external radiative forcing depends critically on the response of water vapor.

We note, however, that Mount Pinatubo does not provide a perfect proxy for global warming, because the nature of the external radiative forcing obviously differs between the two.

Between 801 and 1800 ce, the surface cooling trend is qualitatively consistent with an independent synthesis of terrestrial temperature reconstructions, and with a sea surface temperature composite derived from an ensemble of climate model simulations using best estimates of past external radiative forcings.

Sensitivity experiments accounting only for the external radiative forcings do not reproduce the slowdown.

A more likely scenario for interpretation of the observed warming of the early 20th century might be a smaller (and therefore more likely) realization of internal variability coupled with additional external radiative forcings.

One of the first diagrams should be the AR5 radiative forcing diagram which shows all external radiative forcings, including all the different anthropogenic ones.

Not exact matches

Since OHC uptake efficiency associated with surface warming is low compared with the rate of radiative restoring (increase in energy loss to space as specified by the climate feedback parameter), an important internal contribution must lead to a loss rather than a gain of ocean heat; thus the observation of OHC increase requires a dominant role for external forcing.

Gerald Marsh offered this opinion in «A Global Warming Primer» (page 4 - excerpt) «Radiative forcing is defined as the change in net downward radiative flux at the tropopause resulting from any process that acts as an external agent to the climate system; it is generally measured iRadiative forcing is defined as the change in net downward radiative flux at the tropopause resulting from any process that acts as an external agent to the climate system; it is generally measured iradiative flux at the tropopause resulting from any process that acts as an external agent to the climate system; it is generally measured in W / m2.

«Radiative forcing Radiative forcing is the change in the net, downward minus upward, radiative flux (expressed in W m — 2) at the tropopause or top of atmosphere due to a change in an external driver of climate change, such as, for example, a change in the concentration of carbon dioxide or the output of the SuRadiative forcing Radiative forcing is the change in the net, downward minus upward, radiative flux (expressed in W m — 2) at the tropopause or top of atmosphere due to a change in an external driver of climate change, such as, for example, a change in the concentration of carbon dioxide or the output of the SuRadiative forcing is the change in the net, downward minus upward, radiative flux (expressed in W m — 2) at the tropopause or top of atmosphere due to a change in an external driver of climate change, such as, for example, a change in the concentration of carbon dioxide or the output of the Suradiative flux (expressed in W m — 2) at the tropopause or top of atmosphere due to a change in an external driver of climate change, such as, for example, a change in the concentration of carbon dioxide or the output of the Sun.»

Prevdi and Polvani (2014) suggest quite convincingly that this is a significant constraint in the use of external mean global radiative forcing.

When external forcing increases, the radiative imbalance causes the oceans to gain heat.

Radiative forcing - Radiative forcing is the change in the net, downward minus upward, irradiance (expressed in W m - 2) at the tropopause due to a change in an external driver of climate change, such as, for example, a change in the concentration of carbon dioxide or the output of the Sun.

The AR5 radiative forcing diagram is for changes in external forcings only; it doesn't include the feedbacks.
