Trends Online - A Compendium of Data on Global Change

This website provides an online compendium of frequently used time series of global-change data. It includes historical and modern records of atmospheric concentrations of carbon dioxide and methane, isotopic measurements for atmospheric greenhouse gases, and estimates of global, regional, and national carbon dioxide emissions from the combustion of fossil fuels. Of particular interest is data relating to carbon flux from land-cover change, long-term temperature records, and the total cloud amount over China. {{LINK_LABEL_GO_TO_WEBSITE}}
