I predict that, if you throw a sheet of paper into a fire, barring some extreme situation/intervention, it will catch fire and burn.
So: is that "fact" or just a "prediction" that is open for "opinion"?
Science is all about "predictions" that are based on actual facts and other, well, science. And as the facts accumulate and the foundation of facts grows, these "predictions" increase in accuracy. For example, the science of predicting earthquakes and volcanic eruptions has grown considerably and is now very useful and important. And science made all sorts of "predictions" about quantum-mechanical effects that allow for the components and hyper-miniaturization of the computer (or cell phone) that you are now using to read Slashdot. Some pretty impressive "predictions" there from good-ol' science. Maybe there's something to that "scientific method"?
But for some reason, people who gleefully accept the science that brings them TV and video games and fast cars and fast food... and that made us a space-venturing species... for some reason are quick to dismiss the very same science and scientific method as soon as it threatens their way of like and demands massive behavioral change (and money) from them. Then they latch on rabidly to things like the semantics of words like "prediction" and "theory" with willfully-ignorant disregard for what these words actually mean in a scientific context... which is quite different than colloquial layman usage. Any desperate thing they can so that they don't have to do anything, change anything, or spend anything.
The science and data that climatologists use has been rapidly improving, and the predictions dialed in. The real problem is that as bad as the predictions were, it's now looking like it's going to be even worse. Likely because of the disturbingly growing number of people who'd rather stick their head in the sand than change anything about their life for the sake of future generations. Short-sightedness and selfishness are some of humanity's worst traits, and will likely lead to its extinction. And we have short attention spans, causing us to be unwilling to grasp any concept that happens over large scales. Like my father, who refuses to understand the difference between "climate" and "weather" and every time the snow falls on his house will proclaim that global warming is obviously a hoax.
A loaded super-tanker can take over 3 km to come to a stop, and has a turning radius of 2 km. The bigger the thing you're riding, the longer the lead time you need to affect the future. Well, the earth is a rather big vehicle. Stupid humans look at the micro-fluctuations month to month or year to year, and decide that they're just random noise and discredit them, refusing to extrapolate this or even grasp the concept on how this then extends over decades. If you refuse to believe the iceberg is real until you can reach out and touch it, it's too late to turn the ship. I know of 1500 people who'll back that basic concept up, and that was over 100 years ago.
Plus, your average climate-change denier will proclaim that the earth hasn't already been getting warmer for decades. That's hardly a "prediction".
