The seeds of the wild plant, which grows abundantly across India, produce non-edible oil that can be blended with diesel, to make the biofuel that is part of government efforts to cut carbon emissions and combat climate change.

That, combined with the shrub’s much vaunted ability to flourish on poorly irrigated land, should make it the perfect crop for wasteland in the drought-prone nation.

Researchers analyzing water samples have discovered fragments of Asian carp DNA in Lake Michigan, although there is still no evidence that that fast-breeding fish have breached electric barriers set up along Chicago-area waterways.

“Clearly this is not good news,” said Major General John Peabody, commanding general of the US Army Corps of Engineers’ Great Lakes and Ohio River division.

The cost of failure in Copenhagen was underlined by the UN’s World Meteorological Organisation, which said the current decade was shaping up to be the hottest since accurate records began in 1850.

Scientists long held that most of Antarctica’s continent-sized ice sheet was highly resistant to global warming, and that the more vulnerable West Antarctic ice block would remain intact for thousands of years to come.

The Intergovernmental Panel on Climate Change (IPCC) — whose 2007 report is the scientific benchmark for the UN December 7-18 Copenhagen climate summit — did not even factor melting ice sheets into its forecasts for rising seas.

Obama, hosting India’s leader at the White House a week after visiting top global polluter China, said recent progress meant the world was “one step closer to a successful outcome in Copenhagen.”

Countries must “reach a strong operational agreement that will confront the threat of climate change while serving as a stepping-stone to a legally binding treaty,” he told a press conference with Prime Minister Manmohan Singh.

Danish Climate Minister Connie Hedegaard described the meeting as “very constructive.”

Delegations included major greenhouse gas emitters, including China, the United States, India and Brazil, as well as several island nations and African states that are among the poorest in the world and most vulnerable to climate change.

President Barack Obama’s election returned the United States to active global efforts to fight climate change, but a year later Congress has yet to make good on promises to set the first-ever US caps on carbon emissions.

After a lobbying mission in the US Capitol by UN chief Ban Ki-moon, Kerry said Tuesday the Senate, while unlikely to complete legislation, would give US negotiators an outline before the December 7-18 talks in the Danish capital.

Fresh from a White House meeting with German Chancellor Angela Merkel, who also made a heart-felt plea for a climate protocol in a speech to US lawmakers, Obama held talks with European Union leaders to assure them his administration supported a new treaty at next month’s summit in Copenhagen.

At a EU-US summit here, which continues Wednesday with talks with US Energy Secretary Steven Chu, the Europeans pressed Washington to take action on climate change ahead of December’s climate summit, warning that not enough had been done.

Financial aid from the 27 country EU and other rich, but major polluting countries, to help developing nations confront the challenge of global warming has become a key issue, six weeks before the world climate summit in Denmark.

“We need to find a solution on financing, the internal burden-sharing,” Sweden’s European Affairs Minister Cecilia Malmstroem said Monday. “We need to do that very soon. I think our children cannot wait for us to get the figures right.”

For years they have eked out a tough but decent living, growing vegetables and fruit on floating “fields” made of reeds and composted weeds.

The “Encyclopedia of Life” (http://www.eol.org), a project likely to cost $100 million launched in 2007, says it wants to describe all the 1.8 million known species from apples to zebras within a decade.

“We’re picking up speed,” James Edwards, EOL Executive Director based at the Smithsonian Institution in Washington, said Sunday of the 170,000 entries with content in a common format vetted by experts. A year ago, it had 30,000 entries.
