Melting glacier leaves no room for doubt

Thursday, September 4th, 2008

Huge ice fields in western China’s Tian Mountains are diminishing because of global warming. Jonathan Watts went to Urumqi No1 to see how the local people are being affected.

Up close, the sound of global warming at the face of the Urumqi No1 Glacier is a simple, steady drip, drip, drip. Just 30 metres from the main wall, the flood of meltwater becomes so powerful that it cuts a tunnel under the floor of grey ice, leaving only a blotchy, wafer-thin crust on the surface. [See Guardian video here.]

Compared with the collapse of ice shelves in the Antarctic, the melting of the mountains in China’s far west is one of the less spectacular phenomena of global warming, but it is a more immediate cause of concern and hope.

There is concern because this glacier — more than almost any other in China — is a natural water regulator for millions of people downstream in the far western region of Xinjiang. In winter, it stores up snow and ice. In summer, it releases meltwater to provide drinking and irrigation supplies to one of the country’s most arid regions. It brings hope because its rapid shrinkage is helping to set off climate-change alarm bells in a country that emits more greenhouse gases than any other.

The Urumqi No1 Glacier is so named because it was the first ice field to be measured in China. Since 1953, scientists have been monitoring its thickness and length, analysing traces of pollution and tracking changes in temperature at this 3,800-metre altitude. The results leave no room for doubt that this part of the Tian (Heaven) mountain range is melting.

‘Big Dry’ turns farms into deserts

Monday, September 1st, 2008

In the once-lush fields of South Australia, on land that borders the state’s world famous Lower Lakes, farmer Nigel Treloar rounds up the herd with the help of his off-road motorbike.

It is one of the few things that has got easier as a result of Australia’s worst drought in 100 years.

That is because he used to have 800 cows and now he only milks 250. There is not enough irrigation water from the nearby lakes to sustain a bigger herd.

Nigel took me to nearby Lake Albert, to what used to be a vast expanse of water. But now its waters have receded and much of it resembles a moonscape.

The pump and pipeline that once irrigated his land now lie in the open-air rather than underwater. He has been chasing the retreating water and has been losing the race.

“We’d be up to our waist in water here and it would be navigable,” Nigel told me, after we had walked out 100 metres from what used to be the shoreline.

“You could come out here with boats. All the fishermen would be up and down with their fishing gear and pulling in the catch.”

“But this is the middle of winter and it looks like a desert.”

There are puddles of water but they are brown-tinged and unwelcoming. The cows will not drink it. So high is the salt content that it stings and burns their mouths.

Spain sweats amid ‘water wars’

Monday, September 1st, 2008

Spain is experiencing its worst drought in 40 years. Climate experts warn that the country is suffering badly from the impact of climate change and that the Sahara is slowly creeping north – into the Spanish mainland.

Yet in Spain itself there is little consensus about what is to be done. Indeed, such is the disagreement that journalists and politicians alike are calling it “water wars”.

A farmer and politician, Angel Carcia Udon, said: “Water arouses passions because it can be used as a weapon, a political weapon, just as oil is a political weapon.”

And water in Spain has set region against region, north against south and government against opposition.

When the city of Barcelona nearly ran out of water earlier this year, the fountains were switched off and severe restrictions were introduced.

The government of Catalonia pleaded for water to be transferred from rivers like the Ebro – causing a furious row between the regions.

Instead, the city shipped in millions of litres of water from France and accelerated work on the giant desalination plant on the edge of Barcelona, which promises to provide 180,000 cubic metres of water a day.

Parched land

But Barcelona is not alone in its insatiable thirst. Apart from the far north, the entire country is suffering, especially the parched areas on the Mediterranean coast, from Catalonia, down through Valencia, Alicante, Murcia and Almeria.

Recycled Sewage: Coming to a Tap Near You?

Saturday, August 30th, 2008

Is recycled sewage water coming to a tap near you? If you live in certain parts of the developed world—including areas of the united States—the answer, perhaps surprisingly, is yes.

Persistent droughts and competition for resources are leading to increased use of recycled sewage for drinking water and fertilizer, water experts say.

You know what he’s doing…In developing countries human waste is already used by an estimated 200 million farmers, according to a recent report by the Sri Lanka-based International Water Management Institute (IWMI).

Now wastewater use is gaining steam in the developed world too, though in rich countries, the water undergoes a cleansing process before being pumped out to taps.

“Wastewater recycling is something we will have to rely more heavily on,” said Shivaji Deshmukh, program manager for the groundwater replenishment system at the Orange County Water District in southern California.

Orange County has been recognized for its innovative sewage system, which collects what people flush down the toilet, separates its components, then treats the wastewater to drinking-water standard.

The county water district pumps the treated wastewater into underground caverns, where it is stored and later used as tap water or irrigation water.

Letter to a young idealist

Sunday, July 20th, 2008

R.,

A few more thoughts along the same lines I talked about previously.

All of humanity’s history has been a series of incremental advances along multiple paths; business, social organization, military, agriculture, technological, etc. In all of this, the thought has primarily been to advance, empower and grow.

Now, for the first time in humanity’s history, we have filled the planet and have begun to hit various unyielding limits; water, food, oil, pollution, as well as limits having to do with how much impact we can have on the biosphere without causing huge shifts in the demographics of various species and even causing their extinctions.

It is clear, if humanity wants to continue to live indefinitely on this planet, that we are going to have to shift from a growth and advance strategy in all we do to one predicated on establishing a steady-state and sustainable balance with the biosphere around us.

We cannot use renewable resources faster than they can regenerate. We cannot occupy more of the planet’s surface than is consistent with allowing the rest of the planet’s biology to exist and flourish. These both imply that our population has to come down to some sustainable number and be held there. We have to come up with ways to govern ourselves that are consistent with establishing and maintaining these essential balances. Nation against nation, system against system is not compatible with long term survival. The ultimate goal and purpose of government in an enlightened world should be to secure all of our futures (we and all the rest of the planet’s biology) and maintain the balance.

We could, if we cut our population to sustainable levels and learned to live within a sustainable footprint on this planet, exist here for tens of thousands of years and maintain a decent quality of life for all those who are alive at any specific point in time. We do not have to give up comfort or technology – we just have to dial our impact on the planet back to sustainable levels and stay with in those levels.

Anything that the Gates Foundation or any other forward looking organization works on that does not include long term goals like these is likely in the big picture to just be a shuffling of our problems from one place to the other rather than a real indefinite-term planet-wide solution to how our species is going to solve the problem of learning to live here without fouling our nest for ourselves and all the other species that depend on this planet’s biosphere.

South Australia drought worsens

Saturday, July 19th, 2008

A long-running drought in Australia’s main food-growing region, the Murray-Darling river basin, has worsened, a new report says.

Three months of dry weather and the driest June on record have plunged the area back into drought, the Murray-Darling Basin Commission says.

Crossing much of south-east Australia, the Murray-Darling is the country’s most important river system.

The basin produces 40% of Australia’s fruit, vegetables and grain.

Experts say the drought will hit irrigated crops like rice and grapes the hardest, because other crops, such as wheat, depend more on rainfall during specific periods.

Grim picture

Corey Watts, of the Australian Conservation Foundation in Melbourne, told the BBC that drought was becoming a regular occurrence instead of happening once every 20 to 25 years.

“We’ve had a string of reports, official reports, over the last fortnight painting a pretty grim picture for the climate and the future of our economy and our environment,” he said. “So now we’re looking at a future in the next few decades where drought will occur once every two years.”

In Fertile India, Growth Outstrips Agriculture

Monday, June 23rd, 2008

JALANDHAR, India — With the right technology and policies, India could help feed the world. Instead, it can barely feed itself.

India’s supply of arable land is second only to that of the United States, its economy is one of the fastest growing in the world, and its industrial innovation is legendary. But when it comes to agriculture, its output lags far behind potential. For some staples, India must turn to already stretched international markets, exacerbating a global food crisis.

The organisation of denial: Conservative think tanks and environmental scepticism

Saturday, June 21st, 2008

This worrisome research article has appeared in a peer reviewed journal. It’s not telling us anything that we didn’t already know, but it does catalogue the situation and help us steer clear of the hyperbole.

Environmental scepticism denies the seriousness of environmental problems, and self-professed ’sceptics’ claim to be unbiased analysts combating ‘junk science’. This study quantitatively analyses 141 English-language environmentally sceptical books published between 1972 and 2005. We find that over 92 per cent of these books, most published in the US since 1992, are linked to conservative think tanks (CTTs). Further, we analyse CTTs involved with environmental issues and find that 90 per cent of them espouse environmental scepticism. We conclude that scepticism is a tactic of an elite-driven counter-movement designed to combat environmentalism, and that the successful use of this tactic has contributed to the weakening of US commitment to environmental protection.

NSW drought area growing

Tuesday, June 17th, 2008

More than 60 per cent of Australia’s main eastern agricultural state of New South Wales has slid back into drought after a dramatic increase in dry conditions in the past month, the state Government says.

Over the past month, drought grew to cover 62.7 per cent of the state, from 48.4 per cent a month earlier.

“Much of the cropping belt [is] on a knife edge waiting for desperately needed rain,” said the state Minister for Primary Industries, Ian Macdonald.

“All cropping areas are in urgent need of good rainfall to consolidate crops that have been sown and enable remaining seed to be planted.”

Areas that have slipped back into drought include key wheat growing areas in the central western parts of the state as well as the northern slopes and southern areas.

Desert is claiming southeast Spain

Wednesday, June 4th, 2008

Lush fields of lettuce and hothouses of tomatoes line the roads. Verdant new developments of plush pastel vacation homes beckon buyers from Britain and Germany. Golf courses – 54 of them, all built in the past decade and most in the past three years – give way to the beach. At last, this hardscrabble corner of southeast Spain is thriving.

There is only one problem with this picture of bounty: This province, Murcia, is running out of water. Spurred on by global warming and poorly planned development, swaths of southeast Spain are steadily turning into desert.

This year in Murcia farmers are fighting developers over water rights. They are fighting each other over who gets to water their crops. And in a sign of their mounting desperation, they are buying and selling water like gold on a burgeoning black market.

“Water will be the environmental issue this year,” said Barbara Helferrich, spokeswoman for the European Union’s Environment Directorate. “The problem is urgent and immediate.”
