Science of Climate Change – Why Net Zero 2050?

The study of the science of climate change indicates that human activities are the most important drivers determining the physical and biological future of Earth. It demonstrates that failure to limit the production of greenhouse gases and aerosols and to minimize land use change will result in significant weather-related impacts that will not only be considered destructive from a human perspective but will likely result in the next great extinction of life on Earth, the Holocene or sixth extinction. Limiting these impacts and achieving Net Zero 2050 comes at a cost that requires support from all citizens of the global community, a support that is only possible if citizens are informed and confident in the underlying science.
