Sentences with phrase «albedo feedback»

These runs are examined for evidence of accelerated climate change associated with the removal of sea ice, particularly due to increasing surface albedo feedback.

Virtually ice - free summers in the arctic sea could well arrive by 2030, with troubling implications for accelerated albedo feedback and possibly disruptive changes in the jet stream.

It probably had to do with things like albedo feedbacks and possibly solar forcings that we don't understand yet.

New techniques that evaluate surface albedo feedbacks have recently been developed.

I have a question about the potential albedo feedback effect on a ablating ice sheet surface.

Hall, A. & Qu, X. Using the current seasonal cycle to constrain the snow albedo feedback in future climate change.

The three studies, using different methodologies to estimate the global surface albedo feedback associated with snow and sea ice changes, all suggest that this feedback is positive in all the models, and that its range is much smaller than that of cloud feedbacks.

Based on evidence from Earth's history, we suggest here that the relevant form of climate sensitivity in the Anthropocene (e.g. from which to base future greenhouse gas (GHG) stabilization targets) is the Earth system sensitivity including fast feedbacks from changes in water vapour, natural aerosols, clouds and sea ice, slower surface albedo feedbacks from changes in continental ice sheets and vegetation, and climate — GHG feedbacks from changes in natural (land and ocean) carbon sinks.

Addressing the seasonal cycle biases would therefore provide a constraint that would reduce divergence in simulations of snow albedo feedback under climate change.

In climatology the term feedback is usually connected to the corresponding feedback loop, e.g ice - albedo feedback [13].

This form of ice - ocean albedo feedback proves to be a major influence on both seasonal and interannual variations in sea ice.

«If you can time your emissions so they have the least impact then you will not trigger these very sensitive regions to start warming by this ice albedo feedback process.»

Arctic cryosphere loss already embodies the problem of accelerating albedo feedback driven by radiative forcing, and arrresting this ominous process may remain beyond the capacity of CO2 policy for decades to come;

Then, one can presumably decompose this «total forcing» into its components which might include WV feedbacks, cloud feedbacks, surface albedo feedbacks etc..

The whole concept of Arctic albedo feedback is based on junk science.

Note extreme temperature maximums of 5 - 8 °C and that multiple ice, atmosphere and ocean processes help reinforce albedo feedbacks (after Wood et al., submitted).

It is also important to note that whereas albedo feedback was not presumed to cause a melting tipping point, others were not examined, most notably the Arctic feedbacks that act via the biosphere and the global climatic energy balance, like tundra methane emissions and taiga biomass degradation.

Typical temperature reconstructions for the late Pliocene however [see one at the top of this story - 3.3 - 3.0 Ma] already show an Earth in which a warmer climatic state is indeed [through for instance ice albedo feedbacks] relatively strong around the poles, and (on average) weaker around the equator, exactly the pattern that is monitored under the current climate warming.

The 2 × CO2 Earth system sensitivity is higher than this, being ∼ 4 — 6 ◦ C if the ice sheet / vegetation albedo feedback is included in addition to the fast feedbacks, and higher still if climate — GHG feedbacks are also included.

Studies of the cryospheric albedo feedback have a long history.
