Greenpeace is sounding the alarm over record ocean heating, saying the seas last year absorbed heat equal to nearly 40 times all the energy humanity consumes. The group links this to 84% of the world's coral reefs suffering bleaching-level heat stress, and blames fossil fuel corporations and industrial meat and dairy production for driving the crisis. It is calling for action to protect the ocean.

Researchers using molecular clock analysis, which estimates when species diverged based on genetic mutation rates, have proposed that animals first originated around 200 million years earlier than the fossil record suggests. If confirmed, the finding would push back the timeline of early animal evolution substantially and reignite debate between genetic evidence and the physical fossil record.
- 3Animals may have evolved 200 million years earlier than thought●Animals may have evolved 200 million years earlier than previously thought, new study suggests
A new study suggests animals may have evolved around 200 million years earlier than previously believed, pushing back the timeline for the emergence of animal life on Earth. The finding is drawing attention from scientists and science readers, as it challenges long-held assumptions about when the first animals appeared in the fossil record and how early life developed on the planet.
- 4Horseshoe Crab Trace Fossils Reveal Life After Extinction Event●Horseshoe crab trace fossils reveal ocean life after extinction event
Researchers have reported horseshoe crab trace fossils that shed light on how ocean life recovered after a major extinction event. The fossils, which record the animals' movement and activity rather than their bodies, offer a rare window into marine ecosystems in the aftermath of the catastrophe. Scientists say such trace fossils can reveal behaviour and survival patterns that body fossils cannot.
