Throughout human history, the climate has influenced the development of societies and shaped the natural systems they depend on. Today, we observe unprecedented changes in the climate system caused by greenhouse gas emissions from the burning of fossil fuels, deforestation and other human activities, making it more important than ever for decision-makers to be informed by high-quality scientific information.

Of course, climate science is not static. New discoveries are continually being made, which is why we must be clear about what we know and where there is still uncertainty. More creative approaches are also needed for communicating climate science in ways that educate, motivate and empower people to take action.

As climate change accelerates, it will become extremely difficult to adapt to rising sea levels, changes in the global water cycle, and decreases in food production, all of which will impact the lives of billions of people around the world.
Avoiding the worst impacts will require substantial and sustained reductions in greenhouse gas emissions starting now. According to the Intergovernmental Panel on Climate Change (IPCC), staying within the internationally agreed two-degree Celsius temperature rise limit can only be realized through urgent and ambitious action to move towards carbon-neutral economies and societies. This session will showcase how climate science can inform actions that support this goal.
