Sir #DavidAttenborough “Things are going to get worse. This is the new extinction. We are in terrible, terrible trouble and the longer we wait to do something about it, the worse it is going to get." #ClimateEmergency
David Attenborough, the voice of Our Planet: “Things are going to get worse”
The voice of some of the most stunning nature documentaries ever made is pessimistic about the future of wildlife on earth.

www.theguardian.com/commentisfre... We are raising the alarm because continuing observations of one of our most important components in the climate system are becoming unsustainable.
Amoc collapse could change Europe’s climate 10x faster than expected. We aren’t ready
The system of ocean current that moves heat in the Atlantic Ocean plays a key role in regulating climate. Today’s monitoring of it may be discontinued

To determine how peatlands will respond to climate change, we can explore how they responded to past events. Our new paper, led by Emily Hollingsworth, does that - elaborating on observations that global warming 56 million years ago enhanced methane cycling. www.sciencedirect.com/science/arti...
