The scientific consensus is clear: Surface and sea temperatures are increasing and this is due to human influence. How come a vocal minority still refuses to accept anthropogenic global warming? And how can YOU communicate the hard science to science deniers?
Well, the science is complex and many factors could affect earth's temperatures, including: orbital changes, sun activity, volcanos, deforestation... This leaves many climate change deniers with a caveat: "Planetary warming is a natural cycle that has occurred throughout earth's history." True--but the warming on Earth since the industrial revolution is not natural, and human activities are responsible. Let's see if some rocket scientists can help us out...
A new, artfully produced NASA model shows the amount of planet warming that can be attributed to all these "natural" factors (orbit, sun activity, volcanos) and the un-natural, human activities (aerosols, deforestation, greenhouse gases). SPOILER: Human activity explains the observed planetary warming from 1890-present. An important note here: NASA is not just a space agency, they are vital to the study of planetary sciences starting here at home, on our planet. #hugascientist
