Warming limiting growth of fish in Tasman sea

Rapidly warming ocean temperatures in some parts of the world could be pushing some fish species to the limit, stunting their growth, increasing stress and raising the risk of death, a study shows. An Australian study, published on Monday in the journal Nature Climate Change, focused on the long-lived fish species called the banded morwong [...]

Record high ocean temps in January outnumber record lows 8:1

Map of sea surface temperature (SST) anomalies (relative to 1961-1990) expressed as percentiles of a modified 2-parameter gamma distribution. The black crosses and dashes indicate that a pixel is, respectively, the warmest or coldest example of that calendar month in the record. Coloured areas are significantly warm (orange and red) or cool (blue and magenta).
