RISClimate Model Simulations of Effects of Increased Atmospheric CO2 and Loss of Sea Ice on Ocean Salinity and Tracer Uptake
Publisher: American Meteorological Society
Abstract: Recent observations show a decrease in the extent of Northern Hemisphere sea ice; this decrease has been attributed to human activities. Climate model simulations are presented that examine how loss of sea ice affects the ...
Lifetime of Anthropogenic Climate Change: Millennial Time Scales of Potential CO2 and Surface Temperature Perturbations
Publisher: American Meteorological Society
Abstract: Multimillennial simulations with a fully coupled climate?carbon cycle model are examined to assess the persistence of the climatic impacts of anthropogenic CO2 emissions. It is found that the time required to absorb ...
Long-Term Climate Commitments Projected with Climate–Carbon Cycle Models
Publisher: American Meteorological Society
Abstract: Eight earth system models of intermediate complexity (EMICs) are used to project climate change commitments for the recent Intergovernmental Panel on Climate Change?s (IPCC?s) Fourth Assessment Report (AR4). Simulations ...
Climate–Carbon Cycle Feedback Analysis: Results from the C4MIP Model Intercomparison
Publisher: American Meteorological Society
Abstract: Eleven coupled climate?carbon cycle models used a common protocol to study the coupling between climate change and the carbon cycle. The models were forced by historical emissions and the Intergovernmental Panel on Climate ...
Investigating the Causes of the Response of the Thermohaline Circulation to Past and Future Climate Changes
Publisher: American Meteorological Society
Abstract: The Atlantic thermohaline circulation (THC) is an important part of the earth's climate system. Previous research has shown large uncertainties in simulating future changes in this critical system. The simulated THC response ...
