Krill: key marine animals shaping oceans’ food webs
A cluster of recent marine sightings shows orcas and dolphins appearing more frequently off the Northumberland coast, while Norfolk Island’s reefs show stress from runoff, dredging plans and El Niño. Scientists warn warming waters threaten coral ecosystems and coastal wildlife.
Meteorological agencies and the UN have reported a very strong El Niño that has continued to intensify in August 2026. Forecasts show record-warm Pacific sea-surface temperatures, rising global heat and an elevated risk of droughts, floods and food insecurity that will push tens of millions more people into acute hunger this year and next.
