Rich nations failing to deliver climate cash

Rich nations are failing to live up to their promise of giving US$30bn to poor countries to help them cope with climate change, according to a report. The money was pledged at last year's Copenhagen summit in order to build trust between rich and poor nations. The scheme – championed by former UK PM Gordon Brown – is supposed to deliver the funds by the end of 2012. But a report to the German government says much of the money has been taken from other aid budgets. If the findings are correct, it confirms allegations by pressure groups that rich countries are repackaging existing funds and presenting them as special climate finance. Campaigners claim programmes to tackle poverty will suffer if this is allowed to happen. … Read ahead

Telling the truth about climate change is good politics 7

There are scattered cranks everywhere, of course, but there’s no other developed democracy in which a major political party is dominated by people who explicitly reject mainstream science. Even conservative parties in most developed nations accept climate change as a crucial challenge. British Foreign Secretary and former Conservative Party leader William Hague last week declared climate change “perhaps the 21st century’s biggest foreign-policy challenge.” The U.K.’s new government, led by conservative David Cameron, has a … Read ahead

Oz: a climate change hotspot

Irrigated by one of the world’s mightiest river systems, the Murray-Darling Basin yields almost half of Australia’s fresh produce. But the basin is ailing and scientists fear that as climate change grips the driest inhabited continent its main food bowl could become a global warming ground zero. The2026 … Read ahead

Is the Flooding in Pakistan a Climate Change Disaster?

UNITED NATIONS — Devastating flooding that has swamped one-fifth of Pakistan and left millions homeless is likely the worst natural disaster to date attributable to climate change, U.N. officials and climatologists are now openly saying. Most experts are still cautioning against tying any specific event directly to emissions of greenhouse gases. But scientists at the … Read ahead

Improving stoves, fighting climate change

Cooking stoves aren’t the leading cause of climate change — scientists agree that dubious distinction likely goes to carbon dioxide from fossil fuels (mostly used by rich countries). But cooking stoves used by many poor families contribute to climate change, too, by giving off a noxious and dangerous soot known as black carbon. It’s created from burning wood crops and other organic matter. “It’s a powerful absorber of sunlight,” Rhitu Chatterjee reports for PRI’s The World, “several hundred times more potent than carbon dioxide.” In India, for example, there are an estimated 150 million households, and virtually all of them have cook-stoves. Analysis of air filters from India by Stockholm University geochemist Orjan Gustafson found that about two-thirds of the soot came from biomass and biofuel combustion. Gustafson believes the vast majority of that comes from cooking. Replacing traditional cooking stoves with more efficient ones could have a dramatic effect on black carbon levels, according to atmospheric scientist V Ramanathan of the University of California San Diego. It won’t stop climate change fully, since the biggest source of climate change still comes from carbon dioxide emissions. But it could take effect quickly. Carbon dioxide can stay in the atmosphere for a hundred years, so cuts in emissions now may not have an effect until the distant future. On the other hand, “if you reduce the black carbon today, they’ll be gone few weeks from now,” according to Ramanathan. “So the effect will be immediate.” But behavioral change is difficult, for both carbon dioxide and black carbon. And replacing traditional cooking stoves with more efficient ones is easer said than done. “You see cooking is a very cultural trait,” Ibrahim Rehman, a scientist at New Delhi’s Energy and Resources Institute, told The World. Rehman has tried to get women to use solar cookers for health reasons, but found people resistant to change. He said: … Read ahead
