This was a particularly large one, so the question is, why did it happen? it may have been because one of the pod was having problems at the end of a pregnancy, a situation which has occurred before. an animal was having difficulty giving birth, all the other animals came around it — to protect it, we assumed — but in the process of doing that, the entire pod came into shallow waters and got left by the receding tide. and examining some of the pod should help experts understand whether pollution or other human activity at sea was in any way responsible. james shaw, bbc news. a famous featu...

The climate crisis can sometimes to like the opposite. you miss the trees because you're so freaked out by the forest. you miss the different facets of this issue because the whole thing can feel so overwhelming. i never wanted, when we're talking about the climate, forget the big picture, i do want to zoom in on one aspect of the climate crisis that doesn't always get a lot of attention, it's the oceans. over the last 50 years, humans have burned enough fossil fuel, will, gas, oil, cut down enough trees that we have generated enormous amount of heat. more than 380's that are jewels of heat. y...

Compared with what's happening now. these are natural changes here. this is a natural system that drives these changes. what we are doing right now, we are increasing the speed of these changes. we see that environments are pretty much getting destroyed. but this is part of the human activity. in huge archives, vital geological records are stored. it's the first time a new epoch has been proposed while we're living through it. geologists now need to put this to a vote before the anthropocene epoch is set in stone. rebecca morrelle, bbc news. julia thomas is professor of history at the universi...

They hold the fingerprints of human activity from the byproducts of fossilfuels, microplastics, and the fallout from nuclear weapons testing. and it's the plutonium from these nuclear tests that's being isolated here to determine which year the anthropocene started. we're looking at the plutonium radioactivity in the early 1950s. that was the point when this almost entirely artificial product was globally dispersed. and we pick it up from the early 1950s in sediments all over the globe. the last epoch change happened more than 11,000 years ago. a record is buried in a bog on the isle of wight....

Scientists have announced the start of a process to declare that we are in a new time period — called the anthropocene — apologies for at the pronunciation, it is a difficult word to pronounce. because of the effects humans are having which can be seen on the whole planet. a core from the sediment of crawford lake in ontario in canada has been selected as the best example of human activity being permanently etched in the geological record. a new epoch isn't something that happens very often, the last time was 11,000 years ago as rebecca morelle explains. heading to a site that records a tu...
