Exclusive: YouGov survey in seven countries tested backing for government and individual action on crisis

Many Europeans are alarmed by the climate crisis and would willingly take personal steps and back government policies to help combat it, a survey suggests – but the more a measure would change their lifestyle, the less they support it.

Analysts nudged their California Carbon Allowance (CCA) 2023 average price forecasts higher on market expectations of future programme tightness but expect near-term price declines into the May WCI auction, while they maintained existing RGGI Allowance (RGA) price forecasts in a placid market.

Watching sea snakes swim through water is soothing – until you remember they are real

Sea snakes are, in animal form, the feeling the deep end of the pool gives you when you are a child, when suddenly you feel you are swimming at night, or when you are in bed but not totally sure the floor beneath hasn’t turned into water and sharks. And because sea snakes aren’t where they’re meant to be, the more you learn about them, the more you encounter all that you don’t know: the words are weird, you know their meaning but can’t read their letters, they are words in a dream – or was it a nightmare?

Black-banded sea kraits, a type of sea snake, hunt with yellow goatfish; in New Caledonia, they are called “stripy sweaters”. Kraits are “elapid”, which means their fangs are always erect.
