This video also looks at whether other planets are also warming, and an Internet myth that NASA is now attributing warming to the sun. In this video I examine the importance of sources -- tracking information back to a source and making sure the source is credible. My sources are cited in the video, but I'll also post them here. Sources are also cited throughout my climate change series. These videos are not a personal opinion or a theory of my own; I'm not a climate scientist or a researcher and I have no qualifications to do anything other than report on what real climate scientists have discovered through their research. So there's no point in disagreeing with me. If you dislike their conclusions, take it up with the researchers I cite. If I've made a mistake in reporting their conclusions, please pooint out the mistake and I will happily correct it. If you think you know better than the experts, write a paper and have it published in a respected, peer-reviewed scientific journal.
