Using this understanding of limits, subsequent Special Reports have assessed relevant literature . SR15 identifies several regions, sectors and ecosystems-including coral reefs, biodiversity, human health, coastal livelihoods, Small Island Developing States, and the Arctic-that are projected to experience limits at either 1.5°C or 2ºC. SRCCL states that land degradation due to climate change may result in limits to adaptation being reached in coastal regions and areas affected by thawing permafrost. SROCC details that risks of climate-related changes in the ocean and cryosphere may result in limits for ecosystems and vulnerable communities in coral reef environments, urban atoll islands and low-lying Arctic locations before the end of this century in case of high-emissions scenarios.
