Geoengineering - the 'declaration' that never was may cause real harm

Andrew Lockley

28th August 2014

It was a great story, writes Andrew Lockley - scientists signing up to a 'Berlin Declaration' imposing an effective 'test ban' on outdoor geoengineering experiments. Except there was no declaration, and scientists never agreed to it. The world's media got it completely wrong, yet the mud will stick - and may cause severe harm in the fight against climate change. more...

On-line activism - from surveillance to ecological footprint

Paul Mobbs

15th August 2014

Campaigning has never been so easy - sign an Avaaz petition here, send an email there ... and the world is soon put to rights, no? No, writes Paul Mobbs. We must examine the impacts and implications of our e-life, from climate change to corporate dominance, and take control of the technologies we increasingly depend on. more...

For the next energy revolution, we must deregulate power grids

Bill Watkins

14th August 2014

How do we spur more microgrids powered by renewable energy? Deregulate, writes Bill Watkins, ending the monopolies enjoyed by centralized energy companies. The alternative is to keep consumers and micro-generators stuck with the energy equivalent of the 'Princess' phone. more...

Building an International Seed Savers Exchange

Andrew Kimbrell / Center for Food Safety

19th July 2014

Recent decades have seen a hardening global clampdown on the rights of farmers to use, save, develop, share, swap and distribute the seeds that produce the food we all eat, writes Andrew Kimbrell - and which constitute an essential common heritage of mankind. Here's his plan to fight back against the seed monopolists ... more...

Avaaz's global 'ebay of seeds' - how did they get it so wrong?

Julian Rose

16th July 2014

Already 56,000 people have pledged to support a global 'internet seed swap' initiative promoted by Avaaz, writes Julian Rose. Trouble is, the plans are deeply flawed, and have been developed without consultation with major seed saving groups worldwide. more...

Synthetic biology - Ecover must come clean

Jim Thomas

16th July 2014

Following The Ecologist's revelation about Ecover's use of synthetic biology to make laundry detergent, the company has put its trials on hold, writes Jim Thomas. But to regain public trust, the company must re-engage honestly with its critics, and its customers. more...

Fear of blackouts is no reason to restrict renewable energy

Marek Kubik

13th July 2014

Our current electricity system cannot accept much wind and solar power because they lack the 'inertia' of spinning turbines that stabilises grid voltage, writes Marek Kubik. But that's no reason to limit renewables - there are new, smart solutions ready for deployment. more...

Nuclear power - small isn't beautiful, safe, or cheap

Justin McKeating / Greenpeace

22nd June 2014

Nuclear power is neither beautiful, nor safe, nor cheap, writes Justin Keating - a message to the United States, where the Obama administration has pledged to waste over $200 million financing the 'Small Modular Reactor' (SMR). more...

The New Sylva - a celebration of Britain's trees

Colin Tudge

30th May 2014

The New Sylva is a worthy successor to John Evelyn's original of 1644, writes Colin Tudge, with superb line drawings and a text that looks more to the future of Britain's trees, than their past. A book for ladies, gentlemen, 'meer woodsmen' and 'ordinary rusticks' alike. more...

UK winter floods - more to come with hotter oceans

Simon Redfern

4th May 2014

A massive citizen-powered climate simulation conclusively links the UK's winter floods to global warming, writes Simon Redfern. Over 33,000 climate models running in 'screen saver' mode show a powerful connection between hotter oceans and UK rainfall. more...
