The BBC reports that global ocean surface temperatures outside polar regions have reached 21.1°C, beating the previous record set in March 2024. The combination of human-caused warming and a developing El Niño is pushing the system into uncharted territory.

Oceans hit record heat as El Niño builds
The day's science news is dominated by a stark climate milestone: global ocean surface temperatures have hit a new record, driven by El Niño on top of long-term warming. Meanwhile, NASA is gearing up for the Roman Space Telescope launch, and a fascinating genetic discovery in octopuses offers a glimpse into the evolution of intelligence.
Climate records
The biggest story today is a troubling new data point from the world's oceans, with implications stretching from weather patterns to marine ecosystems.
Space and exploration
NASA is making moves on multiple fronts, from a major telescope launch to new insights about the Sun's influence on Earth's ancient climate.

NASA has set coverage plans for the Nancy Grace Roman Space Telescope launch, now targeting Aug. 30 aboard a Falcon Heavy. This next-gen observatory is designed to study dark energy and other big cosmological questions.

Two new NASA-funded studies suggest that ancient events in the Sun's history helped shape Earth's unique climate and drove unexplained climatic shifts. The research comes from the SHIELD center, which studies solar wind interactions.

Perseverance captured another transit of Phobos across the Sun on Aug. 12, 2026, using its Mastcam-Z camera. The animation has been tinted to simulate human vision, offering a familiar view of an alien sky.
Life and intelligence
Two stories about animal behavior and evolution offer a reminder that the natural world still holds plenty of surprises.
Smithsonian Magazine covers a new discovery: shallow-water octopuses carry a unique mutation in their ribosomal RNA that improves protein-building accuracy. The finding may explain how these animals evolved such large nervous systems and complex behaviors.
A piece from Defector dives into the mating habits of male redback spiders, noting that only 20% succeed. Some perform a 'sacrificial somersault' to be eaten by the female, a strategy that may boost reproductive success.
