Climate Deal Struck in Durban; Critics Say It Falls Short

Durban, South Africa - Two weeks of contentious United Nations talks over climate change concluded Sunday morning with an agreement by more than 190 nations to work toward a future treaty that would require all countries to reduce emissions that contribute to global warming.

The result, coming as the sun rose after nearly 72 hours of continuous wrangling, marked a tentative but important step toward the dismantling of a 20-year-old system that requires advanced industrialized nations to cut emissions while allowing developing countries — including the economic powerhouses China, India and Brazil — to escape binding commitments.

The deal on a future treaty was the most contested element of a package of agreements that emerged from the extended talks here. The delegates also agreed on the creation of a fund to help poor countries adapt to climate change, and to measures involving the preservation of tropical forests and the development of clean-energy technology.

The European Union had pushed hard for what it called a “road map” to a new, legally binding treaty against fierce resistance from China and India, whose delegates argued passionately against it. They said that mandatory cuts would slow their growth and condemn millions to poverty.

Am I to write a blank check and sign away the livelihoods and sustainability of 1.2 billion Indians, without even knowing what the E.U. ‘road map’ contains?” asked India’s environment minister, Jayanthi Natarajan. “Please do not hold us hostage.

The deal renews the Kyoto Protocol, the fraying 1997 emissions agreement that sets different terms for advanced and developing countries, for several more years. But it also begins a process for replacing it with something that treats all nations equally. The expiration date of the protocol — 2017 or 2020 — and the terms of any agreement that replaces it will be negotiated at future sessions of the governing body, the United Nations Framework Convention on Climate Change.

The United States never signed the Kyoto treaty because it did not accept its division of labor between developed and developing countries. Todd D. Stern, the chief American climate negotiator, said he was hopeful that negotiations in coming years would produce a more equitable arrangement.

The conclusion of the meeting was marked by exhaustion and explosions of temper, and the result was muddled and unsatisfying to many. Observers and delegates said that the actions taken at the meeting, while sufficient to keep the negotiating process alive, would not have a significant impact on climate change.

“While governments avoided disaster in Durban, they by no means responded adequately to the mounting threat of climate change,” said Alden Meyer, director of policy at the Union of Concerned Scientists. “The decisions adopted here fall well short of what is needed.”

Green Energy Could Trigger ‘Catastrophic’ Blackouts

Solar panels and wind turbines are a “volatile” source of power with fluctuations in the electricity supply risking “grid instabilities” and triggering wide-scale blackouts.

Ageing infrastructure and increasingly cross-border electricity networks have heightened the likelihood of a devastating collapse of power supplies lasting months and covering several continents, according to the joint report by Allianz and the Chief Risk Officer Forum.

In eastern Germany, turbines in strong wind can produce more than all German coal and gas plants put together, while the need to switch off turbines in high winds causes a drop-off in electricity of 12GW - equal to two nuclear power plants. Outages are likely if there is too little demand or storage capacity to accommodate the jumps in supply.

Leading risk analysts modelled a worst-case scenario in which transformers are knocked out in the United States, causing outages to cascade through the grid into Canada, Russia and Scandanavia.

Credit cards and cash machines would stop immediately, and petrol pumps and refineries would shut-down within six hours. Back-up generators powering hospitals, stock exchanges, emergency services and sewerage plants could run out of fuel within days.

Industry would grind to a halt, cooling equipment would fail and homes would go without food supplies, water or heating, leaving families spending winter around open fires. Allianz predict it would take a year to get the transformers back online. The cost to insurers would top one trillion dollars and chronic power shortages would continue for up to a decade.

“Blackouts during the last ten years in Europe and Northern America have demonstrated an increasing likelihood of supra-national blackouts with accompanying large economic losses,” the analysts wrote.

“Traditional scenarios only assume black-outs for a few days and losses seem to be moderate, but if we are considering longer lasting blackouts… the impacts on society and economy might be significant,” the report said.

Outages could also be trigged by cyber attacks, terrorist action, natural disasters or solar storms - eruptions of charged particles from the surface of the sun which can distort magnetic fields and destroy electricity transmission lines. One such storm knocked out power for six million Canadians in 1989, with the next forecast for 2012.

Half of new electricity capacity worldwide comes from renewable sources such as wind farms, solar panels and biomass plants - up from just 8pc in 2009.

The report said privatisation of electricity networks had split power generating companies from distributors, removing incentives to invest in and maintain infrastructure - a problem exaccerbated by placing windfarms in remote areas. EU nations need to spend £20-25bn on new grid infrastructure by 2016.

The report highlighted how the failure of back-up generators at the Fukushima plant after the Japanese earthquake caused a Chernobyl-scale radiation leak and closed down 11pc of Japan’s power supply, leaving factories idle and shrinking GDP by 3pc.

A blackout in the US and Canada in 2003, when the failure of one Ohio generating plant knocked out more than 100 others, left 50 million people without four days and cost £3-5bn.
