Climate change can be defined as long-term changes in average climate conditions expected to occur locally, regionally, or globally.
Global warming is defined as the increase in the average global temperature in the parts of the atmosphere closest to the Earth's surface, whether this is a natural occurrence or human-induced.
The Intergovernmental Panel on Climate Change (IPCC) stated in its 2019 special report titled Global Warming of 1,5°C that the rise in global average temperatures must be limited to a maximum of 1.5°C.
Paris Agreement establishes a framework for implementation procedures related to national contributions, mitigation, adaptation, loss and damage, finance, technology and capacity-building, transparency, and the global stocktake for climate action.
Net-zero is fundamentally based on the principle of balancing the increase in greenhouse gases in the atmosphere that cause global warming.
