Big ideas on Climate change

Today’s climate change is a long-term, large-scale rise in Earth’s global average temperature, causing shifts in weather patterns. Some models predict rises in global temperature of 4 degrees Celsius by the end of the 21st Century, which could make advanced civilisation unsustainable, lead to a major reduction in the human population, and cause extinction for many other species. The UN aims to keep temperature rise to between 1.5 - 2 degree C. “The Earth’s climate is changing at a rate that has exceeded most scientific forecasts” UNHCR 2018.
