'Keeping 1.5˚C within reach' fundamentally requires understanding and supporting the climate science and knowledge that can help countries craft ambitious action and mitigate risks associated with likely overshoot and the need to return to levels of global warming at or below 1.5˚C. This panel event, convened by the COP Universities Alliance of Australian and Pacific universities, brings together academic and practitioner perspectives on the science of 1.5˚C, overshoot and return, and pathways forward for aligning policy, finance and action with the Paris Agreement's 1.5˚C threshold.
