Global warming is real

You may have heard that global warming isn’t happening, or that it’s a hoax, or that it has “paused” in recent years, or that it’s happening but it’s not caused by humans. These rumors are false. The fact is that global warming is happening, and it’s caused by humans. We have many lines of evidence that support this conclusion [1]. The overwhelming majority of climate scientists and scientists in other fields agree [2]. Nevertheless, some vested interests sow doubt to delay the changes that humans must make to avoid warming Earth too much. Mostly, it’s the fossil fuel industries – the coal and oil companies – that resist, because their products release carbon dioxide when burned, and carbon dioxide is what warms Earth’s atmosphere. The fossil fuel industries have a lot of influence in governments around the world, and they have a lot of money to spend on advertising [3]. [more]
