|Do volcanoes or an asteroid deserve blame for dinosaur extinction?

Scientists have obtained more precise dates for the Deccan Traps volcanic lava flows, linking peak activity more closely to the asteroid or comet impact 66 million years ago and the coincident mass extinction. But if greenhouse gases emitted before the impact created a hothouse climate that set life up for a fall when the impact cooled the planet, those gases did not coincide with the largest lava flows from the Deccan Traps.

Fairy circles are round gaps in arid grassland that are distributed very uniformly over the landscape and only occur along the Namib Desert in southern Africa and in parts of Australia. Scientists have got to the bottom of this with soil investigations and drones. The results suggest Australian fairy circles were caused by processes like the weathering of the soil by heavy rainfall, extreme heat and evaporation.
