In 2015 the landmark Paris agreement has responded to the insight gained from the 5th assessment report of the Intergovernmental Panel on Climate Change (IPCC, on the degree of observed and projected climatic changes, the impacts observed and projected for the future and the finding that humankind has all the instruments in hand for successful mitigation of climate change to support sustainability. The Special Report on Global Warming of 1.5°C has added strong evidence that every bit of warming matters, every year matters in terms of reducing emissions, and every choice matters to maximize the benefits of responses to climate change for sustainability. Accordingly, the Special Report on Oceans and the Cryosphere under Climate Change has evidenced the responses of the ocean, glaciers, ice sheets, sea ice, permafrost to different degrees of warming, and their cascading effects, including for ocean life, and the scale of challenges related to sea level rise for coastlines and settlements. The Special Report on Climate Change and Land has explored climate related risks and response options related to terrestrial ecosystems, agriculture and food security. Building on a rigorous assessment of the state of scientific knowledge, all three special reports provide rich information to inform policy choices to respond to such challenges, reducing the risks of climate change by ambitious mitigation and adaptation efforts, conserving and restoring natural ecosystems and biodiversity as well as initiating society to transition into a future that supports sustainable and climate resilient development for all. The the preparation of the Sixth Assessment IPCC report is currently underway to build on these special reports and provide the most comprehensive assessment of the state of the art understanding of our changing climate, at the global to regional scales, associated impacts and risks, and response options.
