But while Scripps is trying to tie the record-high ocean reading to the broader wave of media coverage on global heat waves, there are a few caveats to note about what the scientists found.
First, these measurements are taken from a pier that’s near the shoreline, which would not necessarily make it representative of the entire Pacific Ocean, and therefore easily influenced by local weather events.
The “anomalously warm temperatures for the past week” that Scripps researchers observed at their pier somewhat mirror the temperature pattern in 1931, and indeed, the daily records broken in the past week have been very close to readings from 87 years ago.
There is an upward trend in temperature readings from Scripps’ pier, but the trend seems to also broadly coincide with the flipping of a natural ocean cycle, the Pacific Decadal Oscillation, to its warm phase. That flip occurred around 1976.
