OSLO, Oct 1 (Reuters) – The Nobel Peace Prize will be announced just three weeks before world leaders gather for a climate summit that scientists say could determine the future of the planet, one reason why prize watchers say this could be the year of Greta Thunberg. With the COP26 climate summit set for the start of November in Scotland, that issue could be global warming. While parliamentarians from any country can nominate candidates for the prize, in recent years the winner has tended to be a nominee proposed by lawmakers from Norway, whose parliament appoints the prize committee. But other documents, including this year’s full list of 329 nominees, are kept behind an alarmed door protected by several locks at the Norwegian Nobel Institute, to be made public in 50 years. It would take another 41 years for Monnet’s creation, the EU, to finally win the prize in 2012.
