Global Warming Posters
Global warming has been measured since pre-industrial times and is closely connected to climate change. Measurements show the long-term rise in temperature of Earth's surface due to human activities, especially burning follis fuels, but climate change is also caused by natural forces like volcanoes. These activities emit gasses that cause the greenhouse effect and block heat from escaping from the Earth. Global warming posters cover all aspects from industrial pollution to atmospheric phenomena.
