  • Taking Stock: the Field of Climate and Security
    Curr. Clim. Change Rep. (IF 6.095) Pub Date : 2018-09-29
    Joshua Busby

    Purpose of ReviewAfter nearly 15 years of study, what do we know about the relationship between climate change and security? How can scholars of climate and security inform the world of practice? These questions animate this article, with an eye towards avoiding the twin traps of policy incoherence and academic irrelevance. Recent FindingsThe last 15 years of study has focused on whether climate change

  • The Trajectory Towards a Seasonally Ice-Free Arctic Ocean.
    Curr. Clim. Change Rep. (IF 6.095) Pub Date : 2018-09-26
    Dirk Notz,Julienne Stroeve

    Purpose of ReviewThe observed substantial loss of Arctic sea ice has raised prospects of a seasonally ice-free Arctic Ocean within the foreseeable future. In this review, we summarize our current understanding of the most likely trajectory of the Arctic sea-ice cover towards this state. Recent FindingsThe future trajectory of the Arctic sea-ice cover can be described through a deterministic component

    Annalisa Cherchi; Tercio Ambrizzi; Swadhin Behera; Ana Carolina Vasques Freitas; Yushi Morioka; Tianjun Zhou

    Purpose of ReviewSubtropical highs are an important component of the climate system with clear implications on the local climate regimes of the subtropical regions. In a climate change perspective, understanding and predicting subtropical highs and related climate is crucial to local societies for climate mitigation and adaptation strategies. We review the current understanding of the subtropical highs

  • Climate War in the Middle East? Drought, the Syrian Civil War and the State of Climate-Conflict Research
    Curr. Clim. Change Rep. (IF 6.095) Pub Date : 2018-09-06
    Tobias Ide

    Purpose of ReviewThis article reviews existing evidence for a climate-conflict link in Syria and examines how the respective debate reproduces three important shortcomings of climate-conflict research. Recent FindingsThe potential climate-conflict link for Syria can be conceived of as a four-stage process, with various levels of scientific evidence and consensus existing for each stage: (1) climate

  • Exceptional Thermal Tolerance of Coral Reefs in American Samoa: a Review
    Curr. Clim. Change Rep. (IF 6.095) Pub Date : 2018-08-29
    Victoria Barker

    As climate change poses an ever increasing threat to coral reefs globally, understanding why particular corals are resistant to bleaching is paramount to their continued survival. The coral reefs of Ofu Island, American Samoa, provide a living laboratory to examine mechanisms of coral adaptation to extreme thermal conditions and serve as an analog for a future environment impacted by climate change

  • Drought and Fire in the Western USA: Is Climate Attribution Enough?
    Curr. Clim. Change Rep. (IF 6.095) Pub Date : 2018-08-09
    Jeremy S. Littell

    Purpose of ReviewI sought to review the contributions of recent literature and prior foundational papers to our understanding of drought and fire. In this review, I summarize recent literature on drought and fire in the western USA and discuss research directions that may increase the utility of that body of work for twenty-first century application. I then describe gaps in the synthetic knowledge

  • Response of the Intertropical Convergence Zone to Climate Change: Location, Width, and Strength.
    Curr. Clim. Change Rep. (IF 6.095) Pub Date : 2018-08-09
    Michael P Byrne,Angeline G Pendergrass,Anita D Rapp,Kyle R Wodzicki

    Purpose of ReviewThe intertropical convergence zone (ITCZ) is a planetary-scale band of heavy precipitation close to the equator. Here, we consider the response of the ITCZ structure to climate change using observations, simulations, and theory. We focus on the substantial yet underappreciated projected changes in ITCZ width and strength, and highlight an emerging conceptual framework for understanding

  • Polar Climate Change as Manifest in Atmospheric Circulation.
    Curr. Clim. Change Rep. (IF 6.095) Pub Date : 2018-08-02
    J A Screen,T J Bracegirdle,I Simmonds

    Purpose of ReviewDynamic manifestations of climate change, i.e. those related to circulation, are less well understood than are thermodynamic, or temperature-related aspects. However, this knowledge gap is narrowing. We review recent progress in understanding the causes of observed changes in polar tropospheric and stratospheric circulation, and in interpreting climate model projections of their future

  • Blocking and its Response to Climate Change.

    Tim Woollings,David Barriopedro,John Methven,Seok-Woo Son,Olivia Martius,Ben Harvey,Jana Sillmann,Anthony R Lupo,Sonia Seneviratne

    Purpose of ReviewAtmospheric blocking events represent some of the most high-impact weather patterns in the mid-latitudes, yet they have often been a cause for concern in future climate projections. There has been low confidence in predicted future changes in blocking, despite relatively good agreement between climate models on a decline in blocking. This is due to the lack of a comprehensive theory

    Purpose of ReviewThis paper reviews sea level contributions from land ice across the Arctic, including Greenland. We summarize ice loss measurement methods, ice loss mechanisms, and recent observations and projections, and highlight research advances over the last 3–5 years and remaining scientific challenges.

  • Societal Impacts of a Rapidly Changing Arctic
    Curr. Clim. Change Rep. (IF 6.095) Pub Date : 2018-07-03
    Kathrin Stephen

    This review article makes six observations about the current body of research on the societal impacts of a changing Arctic. First, climate change and globalisation are the dominant drivers of societal impacts in the Arctic. Second, many contributions focus on the impacts in concrete sectors of society, often from an opportunities-and-risks perspective, which tends to blur the boundary to more policy-oriented

  • The Influence of Arctic Amplification on Mid-latitude Weather and Climate

    Stephen J. Vavrus

    Purpose of ReviewThe rapidly warming Arctic climate may affect weather in middle latitudes, but controversies remain as to mechanisms and robustness. Here, I synthesize recent advances in this rapidly changing field and summarize recommendations on paths forward. Recent FindingsInitial “black-and-white” debates about whether Arctic amplification (AA) affects mid-latitude circulation have evolved toward

  • Drought, Heat, and the Carbon Cycle: a Review

    Sebastian Sippel; Markus Reichstein; Xuanlong Ma; Miguel D. Mahecha; Holger Lange; Milan Flach; Dorothea Frank

    Purpose of the ReviewWeather and climate extremes substantially affect global- and regional-scale carbon (C) cycling, and thus spatially or temporally extended climatic extreme events jeopardize terrestrial ecosystem carbon sequestration. We illustrate the relevance of drought and/or heat events (“DHE”) for the carbon cycle and highlight underlying concepts and complex impact mechanisms. We review
