Humans are modifying and depleting ecosystems, causing extinctions and losses of biodiversity. We are also changing the climate, leading to a bleak and impoverished future for life on our planet.

Reducing greenhouse emissions is the main priority by far.

What will happen to our own species and to life on Earth if we don't stop using fossil fuels? A clear answer can be found in the reports of the Intergovernmental Panel on Climate Change (IPCC, the United Nations body for assessing the science related to climate change).

Such distressing predictions must produce timely changes in energetic and environmental policies.
