Week of meetings could make or break climate effort

---

PARIS, Sept 16 (AFP): Key meetings unfolding in Washington, New York and Pittsburgh in the coming week may determine whether a two-year effort to combat climate change will triumph or be written off as a flop of historic dimensions.
Negotiations under the UN flag are tasked with delivering a treaty in Copenhagen in December to curb the heat-trapping emissions that drive global warming and help poor countries most threatened by drought, flood and rising sea levels.
But for months the process has been deadlocked by rifts between rich and developing countries over how to divvy up the task of slashing greenhouse gases and who should pay for it.
The more than 190 nations at the table cannot agree on the treaty's geometry or even on a procedure for drafting the text.
Pressure is mounting for a breakthrough in what has been dubbed "Climate Week," which kicks off in Washington on Thursday and Friday with a ministerial-level gathering of the world's 17 largest carbon polluters.
Next Tuesday, UN chief Ban Ki-moon will host a climate summit in New York, to be followed by a two-day G20 summit in Pittsburgh, Pennsylvania on September 24-25.
In the corridors, bilateral talks and haggling among blocs of nations will help shape the Copenhagen denouement.
"This is a critical moment for the climate change debate," said US Senator John Kerry, who is fighting to push ambitious domestic energy and climate legislation through the Senate.
"What happens now in September is going to lay a lot of the foundation for what is achievable in December," he told journalists by phone on Tuesday.
"The situation is a little desperate, and time is slipping through our fingers," Brazilian Environment Minister Carlos Minc told AFP in an interview.
"If we want an agreement in Copenhagen, we need to make real progress here and now."
"This is a unique opportunity to show political will and face up to global warming," said Kim Carstensen, head of the WWF's global climate initiative.
"Without new, powerful political impetus at the meetings in September, the climate negotiations could be doomed."
The major stumbling blocks are emissions and money.
Poor and emerging economies say the United States, Japan and the European Union (EU) are historically responsible for today's global warming.
Rich countries acknowledge that charge but say the problem of climate change will only be resolved if China, India and Brazil-the big polluters of tomorrow-take on firm, if lesser, commitments too.
Concretely, developing nations are demanding that wealthy ones commit to cutting carbon pollution by least 40 percent before 2020. An 80-strong bloc of small island states and the world's least developed nations have set the bar even higher, at 45 percent.
That is a far cry from the offers of the table, even from the EU, which has unilaterally vowed to slash emissions by 20 percent by 2020 compared with 1990 levels.
The US's 2020 targets remain modest by comparison:
legislation wending its way through Congress would trim CO2 output by about four percent off the same 1990 benchmark.
