The best and worst from the summit

HIGHLIGHTS

Tuvalu taking on the big nations:

Low-lying Tuvalu was criticised by developed nations for stalling talks by insisting countries agree to warming of no more than 1.5C above pre-industrial levels - a safer target for it than 2C. But the tiny state became a rallying point for countries and observers who felt that the talks lacked ambition, attracting the media spotlight far more successfully than most bigger nations.

Yvo de Boer's cable cars:

The UN climate chief, who is famous for his colourful metaphors, painted a picture early on of the talks as a smooth cable car coasting towards the summit of success. He was then forced to admit that the cable car had ground to an unexpected halt, before proclaiming ahead of the final day that observers should "hold tight and mind the doors - the cable car is moving again".

Fair trade chocolate:

Among the many organic, biodegradable and recyclable offerings at the Bella Centre were tiny tabs of Fair Trade chocolate.The miniature bars were distributed free to sleep-deprived journalists and negotiators and provided a welcome change from conference food.

Arnold Schwarzenegger's Terminator-voiced "I'll be back."

The famous voice appeared for a split second at the end of an otherwise statesman-like speech by the Governator.

LOWLIGHTS

Wrangling over the details:

The conference made slow progress, given that the basic principles - specific offers by industrialised countries of emissions cuts and commitments by China and India to also take action - were in place from the start. Procedural wrangling took up much of the two weeks and delayed talk about the real issues.

Queues:

Observers from environmental, indigenous and business groups queued for hours in the bitter cold waiting to enter the conference venue and many were turned away. Once inside, they faced long queues for food, toilets and security checks. Violence:

The otherwise remarkably tolerant Danes were heavily criticised after police batoned and fired tear-gas at some demonstrators. The largely peaceful protests were directed at UN organisers who barred most observers from the building.
