Summarize the relevant information of each paragraph: The 4 main agreements of the Glasgow climate pact

Emissions
It was agreed countries will meet next year to pledge further cuts to emissions of carbon dioxide (CO2) - a greenhouse gas which causes climate change. This is to try to keep temperature rises within 1.5C - which scientists say is required to prevent a "climate catastrophe". Current pledges, if met, will only limit global warming to about 2.4C.

Coal
For the first time at a COP conference, there was an explicit plan to reduce use of coal - which is responsible for 40% of annual CO2 emissions. However, countries only agreed a weaker commitment to "phase down" rather than "phase out" coal after a late intervention by China and India.
