The concentration of carbon dioxide in Earth’s atmosphere has reached a record high, according to a report released by the World Meteorological Organization.
High levels of the greenhouse gas are associated with higher global temperatures and other effects of climate change, such as melting polar ice and rising seas.
The WMO report also found that concentrations of two other greenhouse gases, methane and nitrous oxide, have also seen an uptick over the past decade. It’s estimated that about 60 percent of methane emissions come from human activities, such as from landfills, cattle breeding and certain types of agriculture, while the other 40 percent comes from natural sources.
