The IPCC must maintain its rigor

Last year, the Intergovernmental Panel on Climate Change (IPCC) was awarded the Nobel Peace Prize along with Albert Gore Jr., sending a strong message about the importance of the world's future climate. Indeed, for two decades, international scientists and policy-makers contributing to the IPCC process have provided assessments of climate change science, impacts and mitigation, addressing one of the most far-reaching and complex challenges that society has ever faced. Yet this is no time for IPCC to rest on its laurels.
