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 | Deforestation in the Amazon

Deforestation in the Amazon Author: Geoff Zeiss – Published At: 2011-01-25 15:37 – (890 Reads) Why is the Brazilian Amazon being Destroyed? In many tropical countries, the majority of deforestation results from the actions of poor subsistence cultivators. However, in Brazil only about one-third of recent deforestation can be linked to shifted cultivators. Historically a […]

Environment Counts | New evidence about anthropogenic aerosols and climate change – IPCC 5th ASSESSMENT Report

New evidence about anthropogenic aerosols and climate change – IPCC 5th ASSESSMENT Report Author: Geoff Zeiss – Published At: 2014-09-15 17:28 – (2104 Reads) The atmosphere is composed mostly of gases, but it also contains liquid and solid matter in the form of particles. Water aerosols are called clouds. The main constituents of non-water atmospheric […]

Environment Counts | Glacial/interglacial cycles determined by Milankovitch insolation cycles and ice volume

Glacial/interglacial cycles determined by Milankovitch insolation cycles and ice volume Author: Geoff Zeiss – Published At: 2013-08-02 12:44 – (1725 Reads) Although astronomical frequencies corresponding to Milankovitch cycles are found in almost all paleoclimatic records, it is clear that the climatic system does not respond linearly to insolation variations. The best well-known disagreement between the […]

Environment Counts | Causes of Antarctica ice loss found to be complex

Causes of Antarctica ice loss found to be complex Author: Geoff Zeiss – Published At: 2012-07-14 22:27 – (1116 Reads) Nearly 90% of Antarctica’s ice loss is discharged through ice shelves, floating glaciers, into the ocean. The ice shelves also affect the flow of the adjacent grounded ice. Recent examples of sudden break-up events along […]

Environment Counts | Polar bears losing weight as sea ice extent declines :

Published by geoff on 2016-04-06 Sea ice is declining over much of the Arctic. In Hudson Bay the ice melts completely each summer and earlier break-ups are resulting in longer ice-free seasons. A new study examined ice trends trends for 1980–2012 in Southern Hudson Bay. Southern Hudson Bay The researchers compiled break-up and freeze-up dates […]
