Copenhagen climate treaty

Copenhagen climate treaty

With strong appeals for action and sharp rebukes of their critics, diplomats from around the world launched a two-week negotiating summit in Copenhagen today in hopes of producing a new agreement to curb climate change.

“The time for formal statements is over,” said the United Nations’ leading climate official, Yvo de Boer, at an opening ceremony filled with dignitaries and punctuated with a video-screen plea from children warning of dire consequences stemming from warming global temperatures. “The time for restating well-known positions is past. Copenhagen will only be a success it delivers significant and immediate action.”

Desalination

Desalination

Companies will increasingly have to be established in coastal areas owing to the desperate shortage of water in South Africa.

A new report by the international McKinsey consultancy says government needs to make an annual capital investment of $365m (about R2.8bn) in its national water infrastructure. If it does not do so, South Africa could experience a 30% shortage of water by 2030.

Johan van Rooyen, director of water resources planning at the Department of Water Affairs, says government is intensely aware of the situation and is working hard to avoid future water problems.

He points out that it is important for water to be used more economically. South Africans need to learn to employ it more effectively. Consumers in the metropolitan areas could, for instance, with little effort use up to 15% less.

The aim is to save more, but that is only a start. Some water borne toilet systems, for example, use up to 20 litres of water per flush. That’s 20 litres of water that needs to be re-purified. Toilets that use five litres work just as well, Van Rooyen points out.

Linda Page, spokesperson for the Department of Water Affairs and Forestry, says the McKinsey report was compiled with the cooperation of various parties, including the department.

These include bodies from the private sector, such as SABMiller and Coca-Cola.

The McKinsey report indicates that, if South Africa experiences a water shortage, various industries – like the industrial, agricultural and mining sectors – will have to compete with each other for the available water sources.

This could considerably elevate water prices, Van Rooyen points out. He says it could result in industries’ increasingly having to settle at the coast.

Sea water would then be substantially cheaper to desalinate and use than fresh water.

Climate change

Climate change

SCIENTISTS at the University of East Anglia (UEA) have admitted throwing away much of the raw temperature data on which their predictions of global warming are based.

It means that other academics are not able to check basic calculations said to show a long-term rise in temperature over the past 150 years.

The UEA’s Climatic Research Unit (CRU) was forced to reveal the loss following requests for the data under Freedom of Information legislation.

The data were gathered from weather stations around the world and then adjusted to take account of variables in the way they were collected. The revised figures were kept, but the originals — stored on paper and magnetic tape — were dumped to save space when the CRU moved to a new building.

The admission follows the leaking of a thousand private emails sent and received by Professor Phil Jones, the CRU’s director. In them he discusses thwarting climate sceptics seeking access to such data.

In a statement on its website, the CRU said: “We do not hold the original raw data but only the value-added (quality controlled and homogenised) data.”

The CRU is the world’s leading centre for reconstructing past climate and temperatures. Climate change sceptics have long been keen to examine exactly how its data were compiled. That is now impossible.

Roger Pielke, professor of environmental studies at Colorado University, discovered data had been lost when he asked for original records. “The CRU is basically saying, ‘Trust us’. So much for settling questions and resolving debates with science,” he said.

Jones was not in charge of the CRU when the data were thrown away in the 1980s, a time when climate change was seen as a less pressing issue. The lost material was used to build the databases that have been his life’s work, showing how the world has warmed by 0.8C over the past 157 years.

He and his colleagues say this temperature rise is “unequivocally” linked to greenhouse gas emissions generated by humans. Their findings are one of the main pieces of evidence used by the Intergovernmental Panel on Climate Change, which says global warming is a threat to humanity.

The New Green Economy

Powerful ideas, practical actions

Rebecca Adamson offers Native American views on scarcity, Wall Street, and how to thrive in hard times.

Indigenous peoples have known hard times. There are signs of drought, crop failure, and forced migration over the millennia, and of course these peoples survived centuries of colonialism. When we were looking for some wisdom on building a new economy, I immediately thought of Rebecca Adamson. Native peoples have developed societies that function within ecological limits and counter the tendency of societies to polarize between rich and poor, powerful and excluded. Adamson, a Cherokee, is founder of First Nations Development Institute and First Peoples Worldwide. She works globally with grassroots tribal communities, sits on the boards of the Corporation for Enterprise Development and the Calvert Social Investment Fund, and is an advisor to the United Nations on rural development.

Sarah: When you look ahead at the coming months, perhaps years, of economic downturn, what do you see coming, and what does indigenous experience teach us about what we should be doing?

Rebecca: I’ve gotta say, it’s about time the bubbles burst. I don’t want to see anybody without a home or a job, but Wall Street had to come to reality sooner or later. I just wish they were taking the brunt of it instead of Main Street.

President Obama assumes that through more spending we can stimulate the financial sector. But why would we want to save something that had no productivity for human life? Until we move away from that paradigm, I don’t hold out too much optimism for the next months, or the next years, or even the next seven generations.

What indigenous experience tells us is that an economy is about fairness and equity. It should be for the well-being of your people and the sacredness of creation. You take care of your place because it provides for you. And the place provides for you because you’re protecting it. We have to begin to rethink our economic system so that it’s accountable for our place.

Sarah: So what is an economy for?

Rebecca: The economy used to be about livelihoods and the provision of a household, but we’ve lost that purpose. We have created an economic system with a goal of material wealth, rather than human development.

We need an economy that provides for people. It has to be fundamentally, radically brought back into control and harnessed for the well-being of society. Not for making money, but for making dignified livelihoods and for the betterment of community.

Sarah: It seems to me that there’s a tendency in any society for wealth to concentrate—if you have a little bit more than someone else, you can use that little bit of additional power to get even more than others. How do indigenous societies counter that?

Rebecca: An indigenous system is based on prosperity, creation, kinship, and a sense of enough-ness. It is designed for sharing. Potlatches, give-aways—these involve deliberately accumulating wealth as a person or as a family or as a clan for the sole purpose of giving it away. The potlatch or the give-away takes place at very specific times of life—birth, naming ceremonies, puberty. Often, if you receive a gift during a potlatch, you are then obligated, at some point in the future, to give a gift. That puts in motion a continual, ongoing requirement for redistribution.

Sarah: So someone with very high status can’t accumulate too much wealth?

Rebecca: You can’t get high status unless you give gifts. Here’s an example. We just got back from a visit with the James Bay Cree. I learned there that the very first ceremony that a baby undertakes is called a walk-away ceremony. James Bay is very cold and so the baby’s first days of life are spent inside the lodge.

Once the baby takes his first steps, they prepare for a walk-away ceremony. A hide is tanned, and an elaborate outfit is made for the baby to wear as he takes his first steps away from the lodge. The baby’s family and the clan gather outside. The baby walks away from the lodge as far as he can. Then everybody calls the baby back in. The child is carrying a bundle filled with food. He comes back into the circle of the family and the clan, and then goes from person to person sharing the food. By doing this, a child has learned to both become his own person and to come back to share.

Oceans’ Ability to Absorb Carbon

Oceans’ Ability to Absorb Carbon

Oceans regulate our climate. They play a key role in keeping the world’s “homeostasis” in tact. However, their ability to absorb carbon & keep the climate in balance is dwindling, a new report shows.
In a year-by-year study from 1765 to 2008, researchers found that the oceans are struggling to meet increasing emissions demands. They cannot take in as much carbon as they used to.

The study, published in the November 19 issue of the journal Nature, found that the percentage of fossil fuel emissions the ocean has been taking in since 2000 has decreased by as much as 10%.

Copenhagen

Copenhagen

The World Wide Fund for Nature (WWF) has urged individuals, businesses and community groups to “Vote Earth” ahead of the United Nations (UN) Climate Change Conference in Copenhagen.

The Vote Earth Campaign is about urging world leaders to deliver a new climate deal which is fair and effective in keeping global warming as far below 2 Degrees Celsius as possible. The Heads of State will gather in Copenhagen on 7 December.

“WWF is calling on South Africans to join the global community in Voting Earth by visiting www.wwf.org.za and committing to take steps to reduce their own environmental impact,” explains WWF South Africa’s CEO, Dr Morne du Plessis.
