British weekly journal Nature on Thursday named environmentalist and the head of Nobel-winning Inter-Governmental Panel on Climate Change, R K Pachauri, as its 'Newsmaker of the Year'.

The IPCC was co-awarded this year's Nobel Peace prize with former US vice-president Al Gore [Images].

Earlier, IPCC published its Fourth Assessment Report to guide policymakers about global warming and its impacts.

'Producing that set of reports was the work of hundreds of scientist, all of whom deserve honour -- and all of whom were honoured with the award of the Nobel Peace Prize on December 10,' said Nature.

'But a particular burden fell on the chair, and in that capacity Pachauri worked ceaselessly, and sometimes sleeplessly, to create compromise where necessary while refusing to dilute the key messages from the academic community he serves,' the magazine said.

Receiving the Nobel on December 10, Pachauri had warned the international community that continued negligence in protecting the world's heritage and natural resources could prove extremely harmful for the human race and lead to some irreversible impacts on biodiversity.
