Satellite Data Suggests Sea Level Rise Shifted Into a Faster Gear Around 2012

An analysis presented at the European Geosciences Union meeting suggests global sea level rise accelerated sharply around 2012, potentially reflecting both natural variability and the planet’s faster rate of warming.

Key Takeaways

Researchers reported a jump in average sea level rise from about 2.9 mm/year before 2012 to 4.1 mm/year afterward.
The shift may reflect several drivers, including faster ice loss, warmer oceans, and changes in water stored on land.

Great White Sharks May Face a Dangerous New Limit in a Warmer Ocean

A new report highlighted by Ars Technica argues that heat-retaining sharks and tuna could become physiologically vulnerable as oceans warm, forcing habitat shifts and raising ecosystem-level risks.

Key Takeaways

A new report says mesothermic sharks and tuna could face overheating risks as oceans warm.
These species require unusually high energy and may also face declining food supplies.
