Head of Climate Change at WWF-UK

Climate change is no longer an abstract future threat, it is on our doorstep. The alarm bells are ringing louder than ever. But the lack of response from the world's political leaders is baffling - and will certainly seem so to future generations.

Mart Drake-Knight

Co-Founder of Eco Fashion brand Rapanui

Right now it's so powerful that people are happy to shop in high street stores without any real clue as to where the clothing comes from, what it's made of and who made it - other than it probably came from somewhere in the third world, and that it's going in the bin in a month's time.

As I speak, the world's rainforests continue to be destroyed, wiping out so much of the world's vital biodiversity and removing our chances of storing carbon naturally; and we continue to ignore the painful lessons of the so-called 'Green Revolution' in India by intensifying our food production methods in such blinkered, chemically and technologically-based ways, that the land and the oceans are now both beginning to fail. Tragically, we cannot even plead ignorance of the consequences of our actions, for the scientific evidence is overwhelming and the impacts are well understood.

It is perhaps no surprise that a climate change 'sceptic' has leaked a draft copy of the volume prepared by working group I for the Fifth Assessment Report of the Intergovernmental Panel on Climate Change, the final version of which is scheduled for publication in September 2013.

Mike Barry

Head of Sustainable Business at Marks and Spencer

It's been a mixed year for sustainable business. For every signal telling us to become more sustainable (resource crunch, extreme weather, social disquiet with business) a counter signal (austerity, shale gas discovery, political inertia) suggests that business as usual is the safest thing to do.

Anne Meikle

Head of WWF Cymru

So what did the Welsh government actually unveil at that event in Blaenavon? Was it a white paper which offered a 'ground breaking' plan for legislation which will make Wales a leading light on sustainable development? Having now had time to analyse it, the answer, sadly, is still 'not yet'.

This was meant to be a blog about Waitrose's relationship with fossil fuel giant Shell (Waitrose had been considering plans to open up shops in Shell petrol stations across the country), calling on Waitrose to end their partnership with the mass polluter. But Waitrose must be mind-readers because on Wednesday they did just that.

Four Peruvian indigenous organizations have pledged to sue the government and Argentinian company Pluspetrol over plans to expand gas operations in the Camisea region in the remote Amazon.

All too often women are missing from key discussions on climate change yet we know that due to existing gender inequalities and development gaps, climate change ultimately places a greater burden on women.

Kit Vaughan

CARE International Director of Climate Change and Environment

Instead, what we witnessed was an almost unprecedented and united stand by the world's poorest and most vulnerable countries, together with their developing country allies, to demand the establishment of an 'international mechanism' to address the significant and increasing loss and damage resulting from climate change impacts.

Climate change negotiations have concluded in Doha, Qatar as the 'Doha Gateway' was passed within minutes and with much confusion. The outcome represents a historic shift with the introduction of "loss and damage" into the agreement, but will do little to actually limit warming to 1.5 degrees.

But don't for a minute assume that 'organic' says anything about whether the food you're about to eat is healthy. Organic crisps are still dangerously high in fat and salt. Organic lemon cookies still contain a glut of sugar.

Policy and Communications Director, Grantham Research Institute on Climate Change and the Environment

This was an example of British leadership in the international arena and demonstrated the enormous amount of 'soft power' that the UK can exert by helping poorer nations, many of which will be hit first and hardest by the impacts of climate change.

Alastair Roderick

Research Fellow at the Schumacher Institute for Sustainable Systems

It has become almost a cliché to declare each New Year as critical in international development, but 2013 will be decisive in determining a successful framework for what comes after the Millenium Development Goals.

This week the UN climate change conference in Doha comes to a close. Alongside the news of a royal baby and the Chancellor's Autumn Statement, it is l...
