People in government and the Intergovernmental Panel on Climate Change (IPCC) are talking about global warming. But governments, companies, and other people do not agree on what to do about it. Some things that could reduce warming are to burn less fossil fuels, grow more trees, eat less meat, and put some carbon dioxide back in the ground. Shading the Earth from some sunlight (this is called geoengineering) could also reduce warming but we don't understand how it might change weather in other ways. Also people could adapt to any temperature changes. The Kyoto Protocol and Paris Agreement try to reduce pollution from the burning of fossil fuels. Most governments have agreed to them but some people in government think nothing should change. The gas produced by cows digestion also causes global warming, because it contains a greenhouse gas called methane.
