Polar temperatures have been warming significantly over the past few decades. A comparison between observational temperature records and model simulations shows that temperature changes in both the Arctic and Antarctic regions can be attributed to human activity. The polar regions have long been expected to warm strongly as a result of anthropogenic climate change, because of the positive feedbacks associated with melting ice and snow1,2. Several studies have noted a rise in Arctic temperatures… 

The changing seasonal climate in the Arctic

Observation-driven reanalyses and state-of-the-art climate models in a variety of standardised climate change simulations show that Arctic winter warming is strongly linked to winter sea ice retreat through the associated release of surplus ocean heat gained in summer through the ice-albedo feedback, and to infrared radiation feedbacks.

Regional Evidence of Global Warming

This chapter assesses to what extent the factors causing global warming affect the Baltic Sea area. Summertime near-surface warming in northern Europe exceeds natural internal variability of the

Ongoing and projected greenhouse warming clearly manifests itself in the Arctic regions, which warm faster than any other part of the world. One of the key features of amplified Arctic warming

The Amplified Arctic Warming in the Recent Decades may Have Been Overestimated by CMIP5 Models

Realistically representing the Arctic amplification in global climate models (GCMs) represents a key to accurately predict the climate system's response to increasing anthropogenic forcings. We

Time varying arctic climate change amplification

During the past 130 years the global mean surface air temperature has risen by about 0.75 K. Due to feedbacks -- including the snow/ice albedo feedback -- the warming in the Arctic is expected to

Shifting El Niño inhibits summer Arctic warming and Arctic sea-ice melting over the Canada Basin

It is suggested that identification of the equator-Arctic teleconnection, via the ‘atmospheric bridge', can potentially contribute to improving the skill of predicting Arctic climate.

Contrasting climate change in the two polar regions

The two polar regions have experienced remarkably different climatic changes in recent decades. The Arctic has seen a marked reduction in sea-ice extent throughout the year, with a peak during the

Attribution of observed historical near‒surface temperature variations to anthropogenic and natural causes using CMIP5 simulations

We have carried out an investigation into the causes of changes in near‒surface temperatures from 1860 to 2010. We analyze the HadCRUT4 observational data set which has the most comprehensive set of

Twentieth century bipolar seesaw of the Arctic and Antarctic surface air temperatures

Understanding the phase relationship between climate changes in the Arctic and Antarctic regions is essential for our understanding of the dynamics of the Earth's climate system. In this paper we

The Antarctic Peninsula has warmed significantly since the 1950s. This pronounced and isolated warming trend is collectively simulated by 29 twentieth-century climate hindcasts done for the Fourth
