Almost all researchers studying the effects of climate change are worried about the extent to which feedback loops are hastening global warming. Though past United Nations Intergovernmental Panel on Climate Change reports, which had left out the impacts of feedback were more optimistic than they should have been, the more recent IPCC report in October 2018 took this into account. The IPCC expressed urgency in a new estimate about how much additional carbon dioxide was being added to the atmosphere as a result of the warming of Arctic permafrost.
