Climate change: A sea change

  title={Climate change: A sea change},
  author={Quirin Schiermeier},
A collapse in ocean currents triggered by global warming could be catastrophic, but only now is the Atlantic circulation being properly monitored. Quirin Schiermeier investigates. 
Abrupt Climate Change and the Economy: A survey with application to Oregon
12 p. report and 2 maps depicting the potential impacts of catastrophic sea level rise on Oregon and on the Portland and Tillamook areas due to a collapse of Antarctic and Greenland ice sheets.
Integrated Ocean Management as a Strategy to Meet Rapid Climate Change: The Norwegian Case
This article addresses the Norwegian experience in introducing integrated, ecosystem-based oceans management, emphasizing how climate change, seen as a major long-term driver of change in ecosystems, is addressed in management plans.
Oceanography: Churn, churn, churn
How the oceans mix their waters is key to understanding future climate change. Yet scientists have a long way to go to unravel the mysteries of the deep. Quirin Schiermeier reports.
The response of Mediterranean thermohaline circulation to climate change: a minimal model
Abstract. Physics-based understanding of the effects of paleoclimate and paleogeography on the thermohaline circulation of the Mediterranean Sea requires an ocean model capable of long integrations
Climate change: The tipping point of the iceberg
Could climate change run away with itself? Gabrielle Walker looks at the balance of evidence.What's the point?The idea that passing a hidden threshold could drastically worsen man-made climate change
Rapid Climate Change and Climate Surprises
  • Environmental Science, Geography
  • 2006
One of the great successes of scientifi c ocean drilling has been the identifi cation of rapid and extreme climatechange events in oceanic sediments. The comprehensive coverage and analytical toolkit
Oceans cool off in hottest years
The temperature drop puzzles climate researchers as they struggle to explain the dramatic drop in global temperatures over the past few decades.
The Changing Climate of the Arctic
The first and strongest signs of global-scale climate change exist in the high latitudes of the planet. Evidence is now accumulating that the Arctic is warming, and responses are being observed
Critical vulnerabilities of marine and sea ice–based ecosystems in the high Arctic
The objectives of this paper are to summarise: (1) observed 20th-century and projected 21st-century changes in key components of the Arctic climate system and (2) probable impacts on the Arctic


Greenland's climate: A rising tide
The ice covering Greenland holds enough water to raise the oceans seven metres — and it's starting to melt. How far will it go? Quirin Schiermeier wades into the evidence.
Dynamic sea level changes following changes in the thermohaline circulation
Using the coupled climate model CLIMBER-3α, we investigate changes in sea surface elevation due to a weakening of the thermohaline circulation (THC). In addition to a global sea level rise due to a
Does the ocean–atmosphere system have more than one stable mode of operation?
The climate record obtained from two long Greenland ice cores reveals several brief climate oscillations during glacial time. The most recent of these oscillations, also found in continental pollen
Decline of the marine ecosystem caused by a reduction in the Atlantic overturning circulation
In the simulations, a disruption of the Atlantic meridional overturning circulation leads to a collapse of the North Atlantic plankton stocks to less than half of their initial biomass, owing to rapid shoaling of winter mixed layers and their associated separation from the deep ocean nutrient reservoir.

Influence of CO2 emission rates on the stability of the thermohaline circulation
Present estimates of the future oceanic uptake of anthropogenic CO2 and calculations of CO2-emission scenarios are based on the assumption that the natural carbon cycle is in steady state. But it
Thermohaline circulation hysteresis: A model intercomparison
We present results from an intercomparison of 11 different climate models of intermediate complexity, in which the North Atlantic Ocean was subjected to slowly varying changes in freshwater input.
Increasing River Discharge to the Arctic Ocean
Synthesis of river-monitoring data reveals that the average annual discharge of fresh water from the six largest Eurasian rivers to the Arctic Ocean increased by 7% from 1936 to 1999, a large-scale change in freshwater flux.
Dilution of the Northern North Atlantic Ocean in Recent Decades
Patterns of freshwater accumulation observed in the Nordic Seas suggest a century time scale to reach freshening thresholds critical to that portion of the Atlantic meridional overturning circulation.
Is the Gulf Stream responsible for Europe's mild winters?
Is the transport of heat northward by the Gulf Stream and North Atlantic Drift, and its subsequent release into the midlatitude westerlies, the reason why Europe's winters are so much milder than
