In September 2008, Pugh, accompanied by a team aboard a ship where he slept, attempted to kayak the 1,200 km from Svalbard, across the Arctic Ocean, to the North Pole, but the team abandoned the effort 135 km from the start.
The aim was to further highlight the melting sea ice.
The expedition coincided with some scientists predicting that the North Pole could be free of sea-ice in the summer of 2008, for the first time in thousands of years.
Pugh stated that despite several attempts, they were unable to find a gap in the ice.
In his autobiography Pugh wrote:"Ironically, global warming played no small part in undermining the entire expedition.
We believed that the greater melting of summer ice would open up large areas of sea and allow us to paddle north at good speed.
What we did not fully appreciate was that to the north of us there was a widespread melting of sea ice off the coast of Alaska and the New Siberian Islands and the ice was being pushed south towards us ...
The evidence of climate change was stark.
Fourteen months before I'd sailed north and I'd seen a preponderance of multi-year ice about three metres thick north of Spitsbergen, but this time most of the ice was just a metre thick."
Kuerten won his second French Open title; the trophy was presented to him by Boris Becker.
Kuerten became the first South American to finish the year as World No.
1 in the history of the ATP rankings (since 1973).
It was a close contest with young up-and-comer Marat Safin at the year's last event, the Tennis Masters Cup (in its first year under that name) in Lisbon, Portugal, with one loss meaning that Safin would have been No.

In order to finish the year as the world No.
1 player, Kuerten did what many critics had deemed impossible (for him to do): beat Pete Sampras and Andre Agassi in back-to-back matches on an indoor hard court.
He broke an eight-year hold of players from the U.S. on the year-end No.
1 position.
He also became the first South American to finish in Top 5 in consecutive years since Guillermo Vilas of Argentina in 1977–78. 
California Sea Lions have always been present in San Francisco Bay.
They started to haul out on docks of Pier 39 in September 1989.
Before that they mostly used Seal Rock for that purpose.
Ever since September 1989 the number of sea lions on Seal Rock has been steadily decreasing, while their number on Pier 39 has generally increased.
Some people speculate that sea lions moved to docks because of the 1989 Loma Prieta earthquake, but the earthquake occurred months after the first sea lions had arrived at Pier 39.
It is likely that the sea lions feel safer inside the Bay.
Although the reason for their migration to the pier is unclear, the refurbishing of the docks in September 1989 required the removal of all boats from that area, leaving large open spaces for the sea lions to move into.
Once the project was completed, boat owners returned, but did their best to navigate around the sea lions; no efforts were made to encourage the new guests to leave.
By the end of that year, less than a dozen sea lions frequented the docks at Pier 39.
By January 1990, their numbers had increased to 150 animals.
Owners of the 11 boats docked there began to complain about having to avoid the animals who can weigh up to half a ton, and odor and noise complaints began to pour in.
Press releases caught national attention, and the sea lions began to attract tourists.
Advice from The Marine Mammal Center was to abandon the docks to the animals, and to relocate the boats elsewhere.
Although fluctuations in the number of sea lions at Pier 39 are dramatic, as many as 1,701 (Thanksgiving Week, 2009) have been officially reported at one time, many of whom are recognizable to researchers and others, and some of whom have been unofficially named.
Volunteers and staff at The Marine Mammal Store and Interpretive Center monitor the sea lion population each day, and educational information is provided to tourists who visit from around the world.
Scientists continue to collect information there, adding to knowledge about sea lion health, dietary habits, and behavior.
In November 2009 the more than 1,701 (Thanksgiving Week, 2009) sea lions that had lived at the pier began to leave, and by late December 2009 nearly all were gone; a similar flux in population occurs annually, with the animals returning in the spring.
Although the reason for their seasonal appearance and departure is not known for certain, according to Jeff Boehm, executive director of the Marine Mammal Center in Sausalito, "Most likely, they left chasing a food source," anchovies and sardines.
A handful of sea lions did return in February, and by late May several hundred could once again be seen on Pier 39.
It remains unknown exactly where they went and why.
However, in December 2009, nearly 4,000 sea lions that were identified as members of the California sub-species were seen outside Oregon's Sea Lion Caves, which meant that they were likely the sea lions from Pier 39.
