The G8 on its own favours a halving of harmful emissions by 2050 but industrialising nations like China and India will not sign up to that goal, arguing that their primary commitment is to improve the living standards of their people.

Without them on board, the U.S. will not ratify any agreement to cut its own emissions.

The “vision” declaration has been hailed by G8 leaders as a useful step ahead of 2009 when they will return to the issue and when America will have a new president with a greater mandate to take action.

But green groups are scornful. The WWF’s Global Climate Initiative calls it “pretty pathetic.”

Should world leaders be trying harder, or have fears of climate change have been overstated?

What’s your view?

One of Gordon Brown’s favourite speech writers is leaving Number 10 to return to the Treasury. That gives Brown the perfect opportunity to draft in someone who has the ability to coin the kind of phrases that chime with the electorate and stick in people’s minds.

To date, that is something Brown, whose dismal year in office was underlined on Friday with a humiliating fifth place by-election finish for Labour, has signally failed to do. Sure, Brown wanted to move away from the accusations of endless spin that soured the public mood towards his slick predecessor Tony Blair.

But the mantras Brown has chosen to repeat ad nauseum since he took up the mantle of Prime Minister have failed to stick. Stressing how many people Labour has taken out of poverty in the past decade, or the need to take “long-term decisions” just isn’t working.

People need reassurance over fuel and food prices, over crime and security, but perhaps more than anything they need to be convinced Brown understands — and cares.

Brown — nicknamed the Iron Chancellor during his decade at the Treasury — is right to focus on the long-term. He wants to ensure people can afford to buy homes, that the country slashes its reliance on non-environmentally friendly energy, and that taxpayers have access to good healthcare, education and welfare support.

But with voters feeling the pinch, it’s the short term that’s key, and if Brown wants his messages about the kind of place Britain needs to become longer-term to stick, he might need to think about the kind of sound-bite approach that Blair used so well.

Brown’s tried a more “man of the people” approach but that hasn’t convinced. Voters are not warming to the serious, unsmiling Prime Minister. And if Brown can’t change his manner, then he needs to change the kinds of words he uses.

Of course, he will also need some luck. No amount of “in tune” rhetoric is going to help if people continue to feel he’s not the man to lead them through the economic bad times. But at the moment, his language and demeanour seem to compound voters’ unease. The Iron Chancellor risks becoming the leaden Prime Minister of British history: dull, inert and potentially poisonous.

You could forgive the public for being confused when it comes to knowing where to eat, where to shop and what to buy.

Almost daily we are bombarded with conflicting information about whether food is healthy or not, or good or bad for the environment. For example, some groups say supermarkets should not give out free plastic bags (this week Marks and Spencer brought in a 5p charge), while other stores, such as Sainsbury’s say that is not the answer and will not bring lasting benefit to the environment.

Ramsay’s latest target is food flown in from abroad. “I don’t want to see asparagus in the middle of December,” he says. Most people over 30 can probably remember when a strawberry would never have been seen except during the British summer and the celebrity chef would like to see a return to the culture of eating home-grown produce.

What’s more, environmentalists argue that it is better for the planet, as according to the Department for Food and Rural Affairs, air freight emits more greenhouse gases per food mile than any other form of transport.

Ah, but what about the farmers in some of the poorest countries in the world who are producing the food for our supermarkets? That trade is vital to their wellbeing, with a million farmers and their families in Africa depending on it, according to the Department for International Development.

What’s more DFID says driving six and half miles to buy your shopping emits more carbon than flying a pack of Kenyan green beans to the UK. “Do we, in rich countries, help poor countries to trade their way out of poverty by buying their exports, or do we say no to air-freighting and buy local produce instead?,” DFID asks.

But then the champions of organic food, the Soil Association, argue that DFID has got it wrong and the government is being irresponsible.

So, is Ramsay just serving up a hot topic to help publicise his new TV show? Or is he right, and restaurants should be forced to use local produce?
