Sir Crispin Tickell has an asteroid and a Costa Rican moth named after him - and, soon, an observatory will also bear his name. While he's honoured by the tributes, the British climate-change expert came to Hong Kong to celebrate the achievement of others.
On Friday, Sir Crispin helped launch the Hong Kong Earth Champions Quest - a search for specialists and everyday heroes who have made an environmental difference in this city. The quest 'gets individuals recognised for their efforts, and that has an infectious effect', Sir Crispin said after the kick-off event at the Foreign Correspondents Club in Central.
'It's like a sort of an epidemic of concern, which individuals and Earth Champions can promote.'
Moments earlier Sir Crispin, 77, had delivered the keynote speech, in which he described the costs of 'human-driven change' on the climate.
'The most likely effects in China, as indeed elsewhere, are that we're going to see changes in weather. And we're going to get more extreme events - that's to say more storms ... more destabilisation,' said Sir Crispin.
'We've got an accelerated melting of the Antarctic and the Arctic ice, and, of course, the Himalayan glaciers.'
