The Arctic is undergoing a significant transformation as a result of climate change. A new NASA-led study has revealed that the ice melt is flooding one of the region’s significant ocean currents with fresh water.
Explainer: Nine ‘tipping points’ that could be triggered by climate change
While climate records are being routinely broken, the cumulative impact of these changes could also cause fundamental parts of the Earth system to change dramatically and irreversibly.
70 per cent decline in capelin not due to fishing, say scientists
Capelin are described a “lynchpin” species because a healthy population helps other types of fish. Cod and turbot eat them directly, and without lots of capelin those fish will eat commercially valuable crab and shrimp instead. Scientists blame late spawning for the population drop.
Smallest plankton grow fastest with rising CO2
Could the future of the ocean depend on its smallest organisms? New studies show that increased CO2 in ocean water can disrupt the food chain for larger species that feed on them and potentially impact ocean currents.
