Abstract
Climate change is a pressing challenge to human wellbeing and the health of our planet. As global temperatures rise, so will the climate impacts and risks faced by all of us. Not all regions and people will face these climate risks equally. Poorer countries and small islands will face much bigger climate risks and disasters. People in these vulnerable regions have contributed the least to climate change. We must make huge changes to the way we live to ensure a just and sustainable future for all. These changes will need trillions of dollars each year that is fairly distributed. This article examines the goals of fair global climate finance in building a safer future. We discuss why global climate finance is still only a trickle and how governments, big companies, and others can come together to deliver on climate action.
