Reemergence and Amplification of Tuberculosis in the Canadian Arctic [PDF]
Journal of Infectious Diseases, 2015 Between November 2011 and November 2012, a Canadian village of 933 persons had 50 culture-positive cases of tuberculosis, with 49 sharing the same genotype.We performed Illumina-based whole-genome sequencing on Mycobacterium tuberculosis isolates from this village, during and before the outbreak.

No detectable trend in mid-latitude cold extremes during the recent period of Arctic amplification
Communications Earth & Environment, 2023 It is widely accepted that Arctic amplification—accelerated Arctic warming—will increasingly moderate cold air outbreaks to the mid-latitudes. Yet, an increasing number of recent studies also argue that Arctic amplification can contribute to more severe ...

On the Arctic Amplification of surface warming in a conceptual climate model [PDF]
Physica D: Nonlinear Phenomena, 2023 Over the last century Earth’s surface temperatures have warmed by order 1 K as a global average, but with significant variation in latitude: there has been most surface warming at high Northern latitudes, around 3 times more than in low latitude regions (termed Arctic Amplification), while there has been least warming over the Southern Ocean.

Cold Waves in East China and Their Response to Two Types of Arctic Amplification
Atmosphere, 2020 Cold waves occur frequently in East China, with their cold air source in the Arctic. Changes in the Arctic are often linked with Arctic amplification. The circulation anomaly associated with Arctic amplification is often represented by Arctic Oscillation

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 ...

Robust and perfectible constraints on human-induced Arctic amplification
Communications Earth & Environment, 2023 The Arctic near-surface warming is much faster than its global counterpart. Yet, this Arctic amplification occurs a rate that is season, model and forcing-dependent. The present study aims at using temperature observations and reanalyses to constrain the

Journal of Marine Science and Engineering, 2021 It is a well-known fact that the observed rise in the Arctic near-surface temperature is more than double the increase in global mean temperature. However, the entire scientific picture of the formation of the Arctic amplification has not yet taken final

Tellus: Series A, Dynamic Meteorology and Oceanography, 2016 Arctic amplification of temperature change is theorised to be an important feature of the Earth's climate system. For observational assessment and understanding of mechanisms of this amplification, which remain uncertain, thorough and detailed analyses ...

The Arctic has warmed nearly four times faster than the globe since 1979
Communications Earth & Environment, 2022 Over the past four decades, Arctic Amplification - the ratio of Arctic to global warming - has been much stronger than thought, and is probably underestimated in climate models, suggest analyses of observations and the CMIP5 and CMIP6 simulations.

Historic temperature observations on Nordaustlandet, north-east Svalbard
Polar Research, 2021 Long-term meteorological data for the Arctic are sparse. One of the longest quasi-continuous temperature time series in the High Arctic is the extended Svalbard Airport series, providing daily temperature data from 1898 until the present.
