Middle East Bronze and Iron Age cultures wine production - Durham University

Bronze and Iron Age farmers in the Middle East prioritised wine production over olive growing in times of climatic change. Researchers in our Department of Archaeology and @durhamearthsci.bsky.social analysed charred seeds and wood samples 👉 www.durham.ac.uk/news-events/...

Our sunflower experiment is coming along nicely. No clear relationship between soil amendment and growth yet. But I’m hypothesising we will see a difference in the actual flower and seeds. Time will tell…

Great Barrier Reef suffers worst coral decline on record Reefs have been battered by cyclones and starfish that eat coral, but heat stress driven by climate change is the main cause of damage.

As an Aussie who has visited and marvelled at its beauty over 30 years ago it is disheartening to read of its decline and pressure to survive.

Our grass experiment is coming along very nicely in Cumbria. Rain and warm weather has helped. Now we leave it for a month and see what impact the soil amendments have had.

This morning I am analysing some alcohol / spirit dated back to 1760… oh it smells heavenly. I wonder what carbon sources were used in its creation ???

Ok. It looks like a more daunting task in the field compared to drawing up the designs on Google Earth - I barely see the car!!! Thank heavens for the LFG farmers who have come to the rescue - more photos tomorrow

Shout out 📣 For those of you who follow us, you'll have had the pleasure of being whisked away to the silky, caramel fronds of a Sussex kelp bed thanks to the beautiful images and footage taken by Paul Boniface, from the amazing Sussex Underwater team.

Farmers and I have been battling for over 12 months to get a permit / license to repair non-functioning tidal gates, but it’s too late… the River Winster is now showing signs of decay and death - bureaucracy and stone walling has stopped us from stopping environmental damage

It was great talking to the Sussex Kelp Restoration Project today. For someone who has not analysed any Sussex kelp they were so welcoming and inquisitive it was amazing.

BP shuns renewables in return to oil and gas The energy giant has announced its strategy after rivals also rowed back on green energy plans.

A clear sign that oil is the name of the game. Renewable energy is now getting less investment - a massive u-turn in the fight against human-induced climate change 😡
