“According to one person who has read the drafts, the new policies will include buying up to 50% of the reduction from abroad. If this is true, it means that the UK will not cut its greenhouse gases by 80% by 2050, as the government promised. It means it will cut them by 40%. Offsetting half our emissions (which means paying other countries to cut them on our behalf) makes a mockery of the government’s climate change programme.”

Monbiot writes that “if global justice means anything”, the rich West must of course make deeper cuts than the poorer developing countries. “We have the most to cut and can best afford to forgo opportunities for development”, Monbiot writes on the Guardian.

“Carbon offsetting makes sense if you are seeking a global cut of 5% between now and for ever. It is the cheapest and quickest way of achieving an insignificant reduction. But as soon as you seek substantial cuts, it becomes an unfair, impossible nonsense, the equivalent of pulling yourself off the ground by your whiskers. Yes, let us help poorer nations to reduce deforestation and clean up pollution. But let us not pretend that it lets us off the hook.”

It is, like always, worth a read: The rich can relax. We just need the poor world to cut emissions. By 125%

During the G8 the world leaders failed to agree on specific targets for climate cuts. They only agreed on “substantially reduce” global emissions by 2050, without any legally binding targets or a roadmap. The United Nations Secretary General Ban Ki-moon criticizes the G8 climate outcome and says it’s “not sufficient”, and that “much more needs to be done” if the world is to be able to agree on a new climate agreement during the climate talks in Copenhagen later this year.

“The time for delays and half-measures is over. The personal leadership of every Head of State or Government is needed to seize this moment to protect people and the planet from one of the most serious challenges ever to confront humanity.”

Ban Ki-moon warned in a statement, issued shortly after the G8 climate meetings, that if the world’s leaders “fail to act this year, they will have squandered a unique historical opportunity that may not come again”. But the Secretary General did welcome the G8 long term goal to reduce emissions by 80% by 2050. But said that for it to be credible it requires “ambitious mid-term targets” and “clear baselines”.

“In order to achieve such a global goal, developed countries must lead by example in making firm commitments to reduce their emissions by 2020 on the order of the 25 – 40 per cent below 1990 levels that the Intergovernmental Panel on Climate Change (IPCC) tells us is required. It is disappointing to note that thus far, the mid-term emission targets announced by developed countries in the MEF are not in this range.

Every country must do its part, based on the principle of equity. Developing countries also need to contribute by undertaking national efforts to mitigate emissions that are nationally appropriate, measurable, reportable and verifiable.

Developing countries need funding and technology assistance. Funding is also needed to assist vulnerable developing countries adapt to the harmful effects of climate change.

We stand at a historical crossroads. Business as usual is no longer viable.”

Daniel Mittler, political advisor to Greenpeace International, said this when he was about to leave the G8 Summit in Toyako, Japan:

There are a lot empty water bottles and even more coffee cups lying around the International Media Centre at the G8. The rooms are slowly emptying out and the faces of those remaining are drained and tired. As I am sure is mine. The last three days were wasted days for addressing the global crises we face. But at least we managed to counter the predictable, positive spin leaders put on the pathetic statements they put out here. For one (of gladly many) good media stories on the united NGO reaction against the G8 climate deal click here. Our Home, the Planet needs action. All it got here, was 8 leaders’ signatures who failed to do what is needed…

And of course Bush had to joke about his climate criminal acts when he left the pointless G8 meeting: Bush to G8: ‘Goodbye from the world’s biggest polluter’

President George Bush signed off with a defiant farewell over his refusal to accept global climate change targets at his last G8 summit.

As he prepared to fly out from Japan, he told his fellow leaders: “Goodbye from the world’s biggest polluter.”

President Bush made the private joke in the summit’s closing session, senior sources said yesterday. His remarks were taken as a two-fingered salute from the President from Texas who is wedded to the oil industry. He had given some ground at the summit by saying he would “seriously consider” a 50 per cent cut in carbon emissions by 2050.

You can discuss G8 in our green forum here. Via Making Waves.

Martin Parry, Jean Palutikof, Clair Hanson and Jason Lowe, all four respected and known scientists from the IPCC, have written on The Nature about the dangers of false optimism regarding climate change. They warn that the “damages will be large” if we continue to believe that we have climate change under control.

“We have lost ten years talking about climate change but not acting on it. Meanwhile, evidence from the IPCC indicates that the problem is bigger than we thought. A curious optimism […] pervades the political arenas of the G8 summit and UN climate meetings. This is false optimism, and it is obscuring reality. The sooner we recognize this delusion, confront the challenge and implement both stringent emissions cuts and major adaptation efforts, the less will be the damage that we and our children will have to live with.”

They also warn that a 50% reduction of global emissions below 1990 levels (note that a 50% reduction is often referred to as “stringent” in the political world), that the G8, EU and the UN climate change conference in Bali last December has urged for, “will not avoid major global impacts.”

According to them even at an 80% reduction of global greenhouse gas emissions “damages will be large” and “likely to be unavoidable.”

“Residual damage will be great unless we invest in adaptation now. Much of the damage could be avoided by adaptation, but again, this would require a much larger effort than is currently planned.

Ten years ago one of the authors, Martin Parry, proposed that adaptation would be unavoidable. This view was criticized as ‘defeatist’, but the data now clearly support it.”

Martin Parry, Jean Palutikof, Clair Hanson and Jason Lowe are just a few of all the other scientists that recently have spoken out about the dangers of playing down the effects and risks from climate change.

Their message is clear.

We need strong actions today. Tomorrow will be too late.
