Environment Counts | CO2 lagged rising temperature in the Southern Hemisphere during last deglaciation

CO2 lagged rising temperature in the Southern Hemisphere during last deglaciation Author: Geoff Zeiss – Published At: 2016-08-20 14:56 – (344 Reads) In this study the EPICA Dome C (Antarctica) ice core has been used to measure a high resolution record of atmospheric CO2 and methane concentrations over the last deglaciation about 19,000 to 11,000 […]

Environment Counts | CO2 drove, but did not trigger, warming during last deglaciation

CO2 drove, but did not trigger, warming during last deglaciation Author: Geoff Zeiss – Published At: 2016-08-15 17:06 – (358 Reads) In this study global and regional surface temperatures during the last deglaciation have been reconstructed from proxy temperature records from 80 geographically distributed sites. Comparison with the atmospheric CO2 record reveals that atmospheric CO2 […]

Environment Counts | Southern Ocean warming preceded rising CO2 during the last deglaciation

Southern Ocean warming preceded rising CO2 during the last deglaciation Author: Geoff Zeiss – Published At: 2016-08-13 16:19 – (371 Reads) This important article provides evidence that southern ocean warming pre-dated the rise of atmospheric CO2. Radiocarbon dating of micro organisms living on the deep ocean floor and in surface waters in a marine core […]

Environment Counts | Accounting for global and regional warming during the last deglaciation

Accounting for global and regional warming during the last deglaciation Author: Geoff Zeiss – Published At: 2016-08-09 17:40 – (365 Reads) The last deglacial warming, which stretched from 19 thousand to 11 thousand years ago, was characterized by increases in surface temperatures of 10-15 °C, sea level rise of 80 meters and by increased atmospheric […]

Environment Counts | New evidence affirms interglacial warming linked to small variations in Earth’s orbit

New evidence affirms interglacial warming linked to small variations in Earth’s orbit Author: Geoff Zeiss – Published At: 2016-08-03 18:04 – (749 Reads) Approximately 800,000 years ago, something changed within the climate system that led to glacial/interglacial periods with a cycle time of roughly 100,000 years. In 1941, Milutin Milankovitch introduced his orbital forcing theory […]

Environment Counts | Change in plankton responsible for rapidly increasing nutrient production in North Pacific since 1850 :

Published by geoff on 2013-12-21 The North Pacific subtropical gyre (NPSG) is a major source of carbon and other nutrients to the deep ocean. Primary production in the NPSG has increased in recent decades due to a shift in the dominant forms of plankton to nitrogen-fixing. As a proxy for nitrogen-supported nutrient production in the […]
