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 ...

 

Contribution of Antarctica to past and future sea-level rise

  
Nature, Vol. 531, No. 7596. (31 March 2016), pp. 591-597, https://doi.org/10.1038/nature17145

Abstract

Polar temperatures over the last several million years have, at times, been slightly warmer than today, yet global mean sea level has been 6–9 metres higher as recently as the Last Interglacial (130,000 to 115,000 years ago) and possibly higher during the Pliocene epoch (about three million years ago). In both cases the Antarctic ice sheet has been implicated as the primary contributor, hinting at its future vulnerability. Here we use a model coupling ice sheet and climate dynamics—including previously underappreciated processes ...

 

Snowfall-driven growth in East Antarctic ice sheet mitigates recent sea-level rise

  
Science, Vol. 308, No. 5730. (2005), pp. 1898-1901, https://doi.org/10.1126/science.1110662

Abstract

Satellite radar altimetry measurements indicate that the East Antarctic ice-sheet interior north of 81.6°S increased in mass by 45 ± 7 billion metric tons per year from 1992 to 2003. Comparisons with contemporaneous meteorological model snowfall estimates suggest that the gain in mass was associated with increased precipitation. A gain of this magnitude is enough to slow sea-level rise by 0.12 ± 0.02 millimeters per year. ...

 

Atmospheric composition 1 million years ago from blue ice in the Allan Hills, Antarctica

  
Proceedings of the National Academy of Sciences, Vol. 112, No. 22. (02 June 2015), pp. 6887-6891, https://doi.org/10.1073/pnas.1420232112

Abstract

[Significance] Bubbles of ancient air trapped in ice cores permit the direct reconstruction of atmospheric composition and allow us to link greenhouse gases and global climate over the last 800 ky. Here, we present new ice core records of atmospheric composition roughly 1 Ma from a shallow ice core drilled in the Allan Hills blue ice area, Antarctica. These records confirm that interglacial CO2 concentrations decreased by 800 ka. They also show that the link between CO2 and Antarctic temperature extended into ...

 

Glaciology: Antarctic area is doomed to melt

  
Nature, Vol. 509, No. 7501. (21 May 2014), pp. 403-403, https://doi.org/10.1038/509403b

Abstract

Several of Antarctica's glaciers have already begun an unstoppable meltdown, two studies suggest. Eric Rignot at the University of California, Irvine, and his colleagues used satellite radar to measure the retreat of five glaciers in West Antarctica and found that there is nothing holding the ice sheets back from catastrophic collapse ...

 

Widespread, rapid grounding line retreat of Pine Island, Thwaites, Smith, and Kohler glaciers, West Antarctica, from 1992 to 2011

  
Geophys. Res. Lett., Vol. 41, No. 10. (28 May 2014), pp. 3502-3509, https://doi.org/10.1002/2014gl060140

Abstract

We measure the grounding line retreat of glaciers draining the Amundsen Sea Embayment of West Antarctica using Earth Remote Sensing (ERS-1/2) satellite radar interferometry from 1992 to 2011. Pine Island Glacier retreated 31 km at its center, with most retreat in 2005–2009 when the glacier un-grounded from its ice plain. Thwaites Glacier retreated 14 km along its fast-flow core and 1 to 9 km along the sides. Haynes Glacier retreated 10 km along its flanks. Smith/Kohler glaciers retreated the most, 35 km along its ice plain, ...

 

Key West Antarctic glaciers retreating unstoppably

  

Abstract

[Excerpt] Radar observations of Amundsen Sea area suggest current melting will run away. Several of Antarctica’s most vulnerable glaciers have already begun a runaway meltdown, two new studies suggest. The work provides some of the first detailed forecasts on how quickly glaciers are likely to disappear from a region that has long concerned scientists. One modeling paper finds that ongoing losses at the Thwaites Glacier have permanently destabilized that ice river, which drains into West Antarctica’s Amundsen Sea. The second study ...

 

Marine Ice Sheet Collapse Potentially Under Way for the Thwaites Glacier Basin, West Antarctica

  
Science, Vol. 344, No. 6185. (16 May 2014), pp. 735-738, https://doi.org/10.1126/science.1249055

Abstract

The West Antarctic Ice Sheet (WAIS) is particularly vulnerable to ocean warming-induced collapse. The Thwaites Glacier of West Antarctica is one of the largest WAIS regional contributors to sea level rise, and has been considered to be potentially unstable for many years. Joughin et al. (p. 735) used a combination of a numerical model and observations of its recent geometry and movement to investigate the stability of the Thwaites Glacier. The glacier has already entered the early stages of collapse, and ...

 

Ice plug prevents irreversible discharge from East Antarctica

  
Nature Clim. Change, Vol. 4, No. 6. (4 June 2014), pp. 451-455, https://doi.org/10.1038/nclimate2226

Abstract

Changes in ice discharge from Antarctica constitute the largest uncertainty in future sea-level projections, mainly because of the unknown response of its marine basins1. Most of West Antarctica’s marine ice sheet lies on an inland-sloping bed2 and is thereby prone to a marine ice sheet instability3, 4, 5. A similar topographic configuration is found in large parts of East Antarctica, which holds marine ice equivalent to 19 m of global sea-level rise6, that is, more than five times that of West ...

Decline in a dominant invertebrate species contributes to altered carbon cycling in a low-diversity soil ecosystem

  
Global Change Biology, Vol. 14, No. 8. (August 2008), pp. 1734-1744, https://doi.org/10.1111/j.1365-2486.2008.01611.x

Abstract

Low-diversity ecosystems cover large portions of the Earth's land surface, yet studies of climate change on ecosystem functioning typically focus on temperate ecosystems, where diversity is high and the effects of individual species on ecosystem functioning are difficult to determine. We show that a climate-induced decline of an invertebrate species in a low-diversity ecosystem could contribute to significant changes in carbon (C) cycling. Recent climate variability in the McMurdo Dry Valleys of Antarctica is associated with changes in hydrology, biological productivity, ...

 

Experts agree global warming is melting the world rapidly

  
Science, Vol. 338, No. 6111. (30 November 2012), pp. 1138-1138, https://doi.org/10.1126/science.338.6111.1138

Abstract

Forty-seven glaciologists have arrived at a community consensus over all the data on what the past century's warming has done to the great ice sheets: a current annual loss of 344 billion tons of glacial ice, accounting for 20% of current sea level rise. Greenland's share—about 263 billion tons—is roughly what most researchers expected, but Antarctica's represents the first agreement on a rate that had ranged from a far larger loss to an actual gain. The new analysis, published on page ...

 

Winds of change

  
Science, Vol. 338, No. 6109. (16 November 2012), pp. 879-881, https://doi.org/10.1126/science.338.6109.879

Abstract

Antarctica does not respond to global warming uniformly like a giant ice cube. Changing wind patterns are an unsung force shaping Antarctica's future. Retreating sea ice and stronger winds have caused seawater to mix more deeply, a process that churns sunlight-dependent phytoplankton into the ocean's depths. As a result, phytoplankton biomass has declined by 12% over the past 30 years. Higher on the food chain, that means fewer krill and fish larvae. These creatures are also getting hammered by the loss ...
