This graph features atmospheric temperature and methane levels, a powerful greehouse gas, that combine measurements from Antarctica ice core data as far back as 800,000 years up to the most recent measurements averaged from a global network of air sampling sites. We encourage you to embed this graph directly into your website. The graph is fully customizable to fit your websites' look and feel. This is a free service, but we do ask for a donation if you find this useful. This is a project of the 2 Degrees Institute, a non-profit organization.
