Environment Counts | Hydrofluorocarbons will contribute to atmospheric greenhouse gas buildup even after production ceases :

Chlorofluorocarbons (CFCs) are the primary cause of ozone depletion. Under the Montreal Protocol they are being phased out. They are being replaced by hydrofluorocarbons (HFCs), which are now mainly used in refrigerators and air conditioners (AC). HFCs are potent greenhouse gases and it has been predicted that HFC radiative forcing will be comparable to the CFCs in the early 1990s. Their containment in refrigerating and cooling equipment represents banks, which are building up as production grows. This article shows that the increase in HFC banks represent a substantial future contribution to atmospheric greenhouse gases even after production of the chemicals ceases. Atmos. Chem. Phys., 14, 4563-4572, 2014 doi:10.5194/acp-14-4563-2014

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 […]
