"Drilling into coral reef growth bands - much like dendrochronologists study tree rings - enabled Australian researchers to pinpoint impacts of changing sea temperatures, showing that warming oceans have boosted coral growth in some areas - at least in the short-term. In other areas, oceans have already become to warm for optimum coral growth.
The scientists from the Australian Institute of Marine Science cautioned that, despite those findings, rising ocean temperatures and ocean acidification pose serious long-term threats to coral reefs, explaining that their research helps clarify the relative impact of these two threats to date."
