New Zealand’s new government has vowed to explore ‘blue carbon’ options for removing atmospheric CO₂ to meet net zero goals. But first we need a national strategy for this developing field of science.

The same instruments used to measure earthquakes pick up vibrations as ocean waves put pressure on the sea floor. Four decades of data tell a story about ocean storms.
Giant eddy currents in the sea spread heat. But if trapped in place, they can cause marine heatwaves deadly to sea life. And there’s a big one shaping up off Sydney right now.
The accumulation of synthetic pollutants found in the blubber of killer whales is impacting the marine mammals’ health. Urgent action is needed to tackle the issue.

Understanding how both cloud cover and temperature work to promote coral bleaching provides valuable insight into how reefs will change over various climate scenarios.
A climate overshoot that creates warmer oceans with lower oxygen levels will reduce the suitable habitat for many marine species long after CO₂ levels have peaked and declined.
Scientists collect water and sediment samples to study how the oceans and climate are changing.

As oceans warm, Canada’s marine protections system looks woefully inadequate. New monitoring systems and flexible governance can help Canada protect the areas most likely to have the greatest impact.

Exploring the often unseen, and poorly understood, nuances of diversity within coral reefs may prove essential for ensuring the long-term health of Earth’s oceans.
Ocean temperatures have hit record highs off the Florida Keys. Scientists and volunteer divers are racing to save these valuable creatures.
Is the sun setting on the Atlantic ocean current system? While not impossible, it is certainly not imminent, and overly sensationalist headlines do little to further the cause of tackling the climate crisis.

Recent headlines around the supposed impending collapse of the Atlantic currents remind us of the importance of avoiding sensationalism in facing global warming.
