Climate Change Debate?

Here is the problem as I see it. Though one might be able to argue that humans are causing the slow heating of the planet from everything they burn from wood to oil and even to the organic waste coming out of cattle, goats, chickens etc. worldwide that we raise there are also many other factors. These other factors can be even more important like volcanic eruptions (which have caused things like the French Revolution because people were starving from not being able to grow food because of Icelandic eruptions blocking out too much sun and changing the weather so food couldn't be grown) all the way to asteroid hits which killed off all the large dinosaurs over several years when it hit the gulf of Mexico 65 million years ago. (This also made things so cold and no food could grow for them to eat so they froze to death and starved to death. Only smaller animals who could hide in caves and underground or under the ocean survived.

So, though humans likely are changing the weather to be warmer, volcanic eruptions will always make the weather colder and sometimes keep people from growing food because of pyroclastic glass powder left in the upper atmosphere that sometimes stays there for years because it is so fine and light and it blocks the sun to some degree hitting the earth.

So, even though humans putting up CO2 into the atmosphere from burning wood and other fuels and from their own waste as well as the natural waste of the animals they raise, asteroids and Volcanoes are always going to make the earth colder. So, I could imagine weather getting significantly warmer from human activities and then in some sections earth getting colder from asteroids or volcanoes. So, even though there is a tendency now for the world to get slowly warmer from human activities there could be even a single volcano going off for years or a single asteroid hitting earth that might throw us into an ice age for thousands of years where humans could only easily grow food then close to the equator all over earth.

If you study the history of earth for millions of years all these things have happened over and over again. It only takes one big event like a large volcano or an asteroid hit to change things for hundreds or thousands of years overnight to an ice age or a time where no food can be grown most places on earth.
