COP28 is the 28th annual United Nations (UN) climate meeting where governments will discuss how to limit and prepare for future climate change. The summit is being held in Dubai, from 30 November until 12 December 2023. COP stands for "Conference of the Parties", where the "parties" are the countries that signed up to the original UN climate agreement in 1992.

It is hoped COP28 will help keep alive the goal of limiting long-term global temperature rises to 1.5C. This was agreed by nearly 200 countries in Paris in 2015. The 1.5C target is crucial to avoid the most damaging impacts of climate change, according to the UN's climate body, the Intergovernmental Panel on Climate Change (IPCC). Long-term warming currently stands at about 1.1C or 1.2C compared with pre-industrial times - the period before humans started burning fossil fuels at scale.

As well as progress towards the existing Paris goals, COP28 will concentrate on:

• Fast-tracking the move to clean energy sources, to "slash" greenhouse gas emissions before 2030.
• Delivering money for climate action from richer to poorer countries, and working on a new deal for developing nations focusing on nature and people.
• Making COP28 the "most inclusive" ever.
