Global warming creates ever greater risks for crops and miners

Climate scientists say global warming is heating up the world’s oceans and atmosphere, providing more fuel for tropical cyclones and creating ever greater risks for crops, miners and billion-dollar beachfronts.

The risks from stronger storms flow right through the heart of the global economy, affecting food security and inflation, iron ore and coal production and higher insurance losses.

Particularly vulnerable are Asia’s booming coastal megacities from Manila to Karachi, large areas of the U.S. Gulf and east coast, Australia’s iron-ore and northern coal mines and tropical Asia’s rice-growing river deltas.

Insurers say unrelenting development along coastlines is placing more homes, businesses and infrastructure in the path of destruction that will drive up insurance losses.

United Nations data says 231 million people lived in cities in Asia in 1950. By 2050, that figure is forecast to grow to more than 3 billion.

Climate change and stronger storms are also a growing threat to Asia’s rice crop.

Asia grows 90 percent of the world’s rice and the International Rice Research Institute in the Philippines estimates an additional 8 to 10 million tonnes of rice needs to be produced each year, meaning disruption from droughts, floods and storms can hurt supplies and cause price spikes.

Australian disasters linked to global warming

An architect of Australia’s stalled climate-change policy has linked the nation’s recent natural disasters with global warming and called for a new political push to cut carbon emissions.

Greenland ice sheet retreating and thinning

A glaciologist is warning that the Greenland ice sheet is “retreating and thinning extensively” after a year of record-breaking high temperatures.

Dr Alun Hubbard on Aberystwyth University says its future is “grim” but disputes claims by other experts that it could collapse within 50 years.

He maintains it would be at least 100 to 1,000 years before it “potentially passes any point of no return leading to any widespread collapse”.

Dr Hubbard and his team have been analysing the results of a summer-long expedition.

His team of 15 from Aberystwyth and Swansea universities spent five months on the ice sheet from the beginning of May.

The group camped about 70 miles (112km) up the sheet, and measured the thickness, speed, climate, and other vital statistics using radar, seismic and geophysical equipment.

They found rising temperatures had caused extensive melting in new upper parts of the ice sheet in this “very sensitive polar region of the planet”.

This has generated at least double the quantity of melt water, compared with 2009, which runs off the ice sheet into the Atlantic and Arctic oceans.

There are fears the melting of the entire sheet could raise sea levels globally by about 7m (20ft), and a study last year found it was losing its mass faster than in previous years. Continue reading Greenland ice sheet retreating and thinning

Siberian animals can slow global warming

Posted by: Saving Water SA (Cape Town, South Africa) – partnered with Water Rhapsody conservation systems – 30 November 2010

Wild horses have returned to northern Siberia. So have musk oxen, hairy beasts that once shared this icy land with woolly mammoths and sabre-toothed cats. Moose and reindeer are here, and may one day be joined by Canadian bison and deer.

Reintroducing herds of grazers to Siberia will turn the Tundra into grasslands

Later, the predators will come – Siberian tigers, wolves and maybe leopards.

Russian scientist Sergey Zimov is reintroducing these animals to the land where they once roamed in millions to demonstrate his theory that filling the vast emptiness of Siberia with grass-eating animals can slow global warming.

“Some people have a small garden. I have an ice age park. It’s my hobby,” said Zimov, smiling through his greying beard. His true profession is quantum physics.

Climate change is felt most sharply in the Arctic, where temperatures are warming faster than anywhere else on the planet. Most climate scientists say human activity, especially industrial pollution and the by-products of everyday living like home heating and driving cars, is triggering an unnatural warming of the Earth.

Nine power stations for Lower Orange River

Namibia’s national power utility says plans are moving ahead to construct a series of hydro-electric power stations along the Lower Orange River.

NamPower Managing Director Paulinus Shilamba told IPS that they are now finalising a study on the project with a South African company, Clarkson Power, with whom they signed a memorandum of understanding with last year.

The Lower Orange Hydroelectrical Power Scheme will include up to nine run-of-the-river generating stations on a stretch of the river with the potential to generate between 90 and 120 megawatts of power. Shilamba said Nampower expects to generate 45 megawatts from the first two installations.

“We are going to develop the power generating project in two phases, with the first two sites to be developed by 2013,” he said.

Reporting on the utility’s call for tenders, online publication Engineering News said the scheme calls for water to be diverted through 70 kilometres of underground tunnels and five km of canals to drive turbines and produce electricity. Continue reading Nine power stations for Lower Orange River
