Environment Counts | Study links asthma attacks with shale gas development :

Published by geoff on 2016-07-18 A statistical study has assessed asthma patients from 2005 through 2012 treated at a clinic in Pennsylvania. 35 508 patients with asthma aged 5 to 90 years were identified in electronic health records. Researchers identified 20 749 cases of mild, 1870 of moderate, and 4782 of severe asthma attacks were statistically compared […]

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 | 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 | 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 | Antarctic sea-ice may be thicker than previously thought :

sea-ice Published by geoff on 2014-12-05 Recent advances in autonomous underwater vehicle (AUV) technology have opened up access to the underside of sea-ice. 3D maps of Antarctic sea-ice have been compiled for ten floes using measurements by an autonomous underwater vehicle in the near-coastal regions of the Weddell, Bellingshausen, and Wilkes Land sectors. Antarctic sea-ice […]

Environment Counts | Massive collapse of Antarctica ice shelf likely due to surface warming :

Published by geoff on 2014-09-11 In February to March of 2002, the Larsen-B ice shelf in the Antarctica catastrophically collapsed in one season with a loss of 3,250 square km of floating ice. Larsen B had been stable for 12,000 years since the last glacial period. Larsen B ice sheet collapse Source NASA Radiocarbon-constrained chronologies […]

Environment Counts | Rapid thinning of the Pine Island glacier also occurred 8,000 years ago :

Published by geoff on 2014-02-21 Pine Island Glacier, a major outlet of the West Antarctic Ice Sheet, has been undergoing rapid thinning and retreat for the past two decades. Pine Island Glacier This study shows that Pine Island Glacier also experienced rapid thinning of about a meter per year, which is comparable to modern rates, […]
