An air-conditioned greenhouse
Article Abstract:
Climatologists are debating to what extent sea surface temperature (SST) interacts with cirrus clouds to function as an atmospheric thermostat. V. Ramanathan and W. Collins used data from the satellite-borne Earth Radiation Budget Experiment to deduce that cirrus cloud cover keeps SST from exceeding 305 K. However, Rong Fu and colleagues suggest an alternative model based on a reinterpretation of the satellite data: that fluctuations in the cirrus cover have more to do with shifts in atmospheric circulation than with SSTs. Further knowledge is needed before these hypotheses can be tested.

Global warming, ocean cooling
Article Abstract:
Changes in water temperature and salinity in the northeastern North Atlantic since the 1960s show that global warming is not an unvarying process. J.F. Read and W.J. Gould analysed data from fisheries and other sources and found that moderately deep sea water was both colder and less salty than before, which may indicate at least a temporary reversal of atmospheric warming. Further research is necessary to clarify how North Atlantic circulation relates to climatic changes.
