Hello, I'm Stephenb. An edit that you recently made to Greenhouse gas seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! Stephenb (Talk) 16:00, 27 October 2015 (UTC)
