Trajectories of the Earth system in the Anthropocene

  
Proceedings of the National Academy of Sciences (06 August 2018), 201810141, https://doi.org/10.1073/pnas.1810141115

Abstract

We explore the risk that self-reinforcing feedbacks could push the Earth System toward a planetary threshold that, if crossed, could prevent stabilization of the climate at intermediate temperature rises and cause continued warming on a “Hothouse Earth” pathway even as human emissions are reduced. Crossing the threshold would lead to a much higher global average temperature than any interglacial in the past 1.2 million years and to sea levels significantly higher than at any time in the Holocene. We examine the ...

 

Wave climate in the Arctic 1992–2014: seasonality and trends

  
The Cryosphere, Vol. 10, No. 4. (26 July 2016), pp. 1605-1629, https://doi.org/10.5194/tc-10-1605-2016

Abstract

Over the past decade, the diminishing Arctic sea ice has impacted the wave field, which depends on the ice-free ocean and wind. This study characterizes the wave climate in the Arctic spanning 1992–2014 from a merged altimeter data set and a wave hindcast that uses CFSR winds and ice concentrations from satellites as input. The model performs well, verified by the altimeters, and is relatively consistent for climate studies. The wave seasonality and extremes are linked to the ice coverage, wind ...

 

Host-specific insect herbivores as sensors of climate change in arctic and Alpine environments

  
Arctic and Alpine Research, Vol. 30, No. 1. (1998), pp. 78-83, https://doi.org/10.2307/1551747

Abstract

The distributions of host-specific herbivorous insects along latitudinal and altitudinal gradients, particularly within arctic and alpine environments, provide useful analogs for predicted future changes that are likely to occur over time at any one location, given a gradually changing thermal environment. It is suggested that selected examples of these insect/plant systems can serve as highly responsive sensors of changing climatic temperatures. Distributions of insects that show a restricted occurrence within the overall range of their host plant are predicted to respond ...

Permafrost carbon−climate feedback is sensitive to deep soil carbon decomposability but not deep soil nitrogen dynamics

  
Proceedings of the National Academy of Sciences, Vol. 112, No. 12. (24 March 2015), pp. 3752-3757, https://doi.org/10.1073/pnas.1415123112

Abstract

[Significance] As the climate warms, the carbon balance of arctic ecosystems will respond in two opposing ways: Plants will grow faster, leading to a carbon sink, while thawing permafrost will lead to decomposition and loss of soil carbon. However, thawing permafrost also releases nitrogen that fertilizes plant growth, offsetting some carbon losses. The balance of these processes determines whether these ecosystems will act as a stabilizing or destabilizing feedback to climate change. We show that this balance is determined by the rate ...

 

Intensified Arctic warming under greenhouse warming by vegetation–atmosphere–sea ice interaction

  
Environmental Research Letters, Vol. 9, No. 9. (01 September 2014), 094007, https://doi.org/10.1088/1748-9326/9/9/094007

Abstract

Observations and modeling studies indicate that enhanced vegetation activities over high latitudes under an elevated CO 2 concentration accelerate surface warming by reducing the surface albedo. In this study, we suggest that vegetation-atmosphere-sea ice interactions over high latitudes can induce an additional amplification of Arctic warming. Our hypothesis is tested by a series of coupled vegetation-climate model simulations under 2xCO 2 environments. The increased vegetation activities over high latitudes under a 2xCO 2 condition induce additional surface warming ...

 

Shifts in Arctic vegetation and associated feedbacks under climate change

  
Nature Climate Change, Vol. 3, No. 7. (31 July 2013), pp. 673-677, https://doi.org/10.1038/nclimate1858

Abstract

Climate warming has led to changes in the composition, density and distribution of Arctic vegetation in recent decades1, 2, 3, 4. These changes cause multiple opposing feedbacks between the biosphere and atmosphere5, 6, 7, 8, 9, the relative magnitudes of which will have globally significant consequences but are unknown at a pan-Arctic scale10. The precise nature of Arctic vegetation change under future warming will strongly influence climate feedbacks, yet Earth system modelling studies have so far assumed arbitrary increases in shrubs ...

 

Arctic tree rings as recorders of variations in light availability

  
Nature Communications, Vol. 5 (7 May 2014), https://doi.org/10.1038/ncomms4836

Abstract

Annual growth ring variations in Arctic trees are often used to reconstruct surface temperature. In general, however, the growth of Arctic vegetation is limited both by temperature and light availability, suggesting that variations in atmospheric transmissivity may also influence tree-ring characteristics. Here we show that Arctic tree-ring density is sensitive to changes in light availability across two distinct phenomena: explosive volcanic eruptions (P<0.01) and the recent epoch of global dimming (P<0.01). In each case, the greatest response is found in the ...

 

Coverage bias in the HadCRUT4 temperature series and its impact on recent temperature trends

  
Q.J.R. Meteorol. Soc. (1 February 2014), pp. n/a-n/a, https://doi.org/10.1002/qj.2297

Abstract

Incomplete global coverage is a potential source of bias in global temperature reconstructions if the unsampled regions are not uniformly distributed over the planet's surface. The widely used Hadley Centre–Climatic Reseach Unit Version 4 (HadCRUT4) dataset covers on average about 84% of the globe over recent decades, with the unsampled regions being concentrated at the poles and over Africa. Three existing reconstructions with near-global coverage are examined, each suggesting that HadCRUT4 is subject to bias due to its treatment of unobserved ...
