A solution for constraining past marine Polar Amplification [PDF]

Nature Communications
Most climate proxies of sea surface temperatures suffer from severe limitations when applied to cold temperatures that characterize Arctic environments.

Polar Amplification in the Earth’s Three Poles Based on MODIS Land Surface Temperatures

Remote Sensing, 2023
Polar amplification appears in response to greenhouse gas forcing, which has become a focus of climate change research. However, polar amplification has not been systematically investigated over the Earth’s three poles (the Arctic, Antarctica, and the ...

The Polar Amplification Model Intercomparison Project (PAMIP) contribution to CMIP6: investigating the causes and consequences of polar amplification [PDF]

Geoscientific Model Development, 2019
Polar amplification – the phenomenon where external radiative forcing produces a larger change in surface temperature at high latitudes than the global average – is a key aspect of anthropogenic climate change, but its causes and consequences are not ...

Polar Amplification Due to Enhanced Heat Flux Across the Halocline [PDF]

Geophysical Research Letters, 2020
Polar amplification is a widely discussed phenomenon, and a range of mechanisms have been proposed to contribute to it, many of which involve atmospheric and surface processes.

Polar Amplification and Ice Free Conditions under 1.5, 2 and 3 °C of Global Warming as Simulated by CMIP5 and CMIP6 Models

Atmosphere, 2021
One of the most visible signs of global warming is the fast change in the polar regions. The increase in Arctic temperatures, for instance, is almost twice as large as the global average in recent decades.

Contributions to Polar Amplification in CMIP5 and CMIP6 Models

Frontiers in Earth Science, 2021
As a step towards understanding the fundamental drivers of polar climate change, we evaluate contributions to polar warming and its seasonal and hemispheric asymmetries in Coupled Model Intercomparison Project phase 6 (CMIP6) as compared with CMIP5 ...

Some new evidence using fractional integration about trends, breaks and persistence in polar amplification [PDF]

Scientific Reports
This paper uses fractional integration methods to obtain new evidence on polar amplification. The adopted modelling framework is very general since it allows the differencing parameter to take any real value, including fractional ones, and provides ...

An inter-hemispheric seasonal comparison of polar amplification using radiative forcing of a quadrupling CO₂ experiment [PDF]

Annales Geophysicae, 2020
The numerical climate simulations from the Brazilian Earth System Model (BESM) are used here to investigate the response of the polar regions to a forced increase in CO2 (Abrupt-4×CO2) and compared with Coupled Model Intercomparison Project phase 5 ...

Arctic amplification of climate change: a review of underlying mechanisms

Environmental Research Letters, 2021
Arctic amplification (AA)—referring to the enhancement of near-surface air temperature change over the Arctic relative to lower latitudes—is a prominent feature of climate change with important impacts on human and natural systems.

Correcting for artificial heat in coupled sea ice perturbation experiments

Environmental Research: Climate, 2023
A common approach to assessing how polar amplification affects lower latitude climate is to perform coupled ocean-atmosphere experiments in which sea ice is perturbed to a future state.
