Part 2 of a 4-part series on why the Earth is warming

If you haven’t already read part 1 of this series you can check it out here.

There are many different things that could be warming the Earth. Let’s consider several natural causes that are often cited as being responsible for this warming. To do this, we’ll look at several charts that show the actual temperature of the Earth compared to the predicted temperature based on each potential cause.

Is it Earth’s orbit?

You may not know it, but the Earth actually wobbles a bit on its axis as it spins. This wobble slowly changes over thousands of years, and has even brought about ice ages.

But if we’re looking at the past 125 years, it’s easy to see that the wobble has no real effect on temperature.

Is it the sun?

The sun’s temperature is another thing that changes over time. Heck, eventually its going to become so big it’ll completely engulf the Earth! It must be what’s causing the the temperature rise.

Nope. These temperature changes happen over extremely large timescales. The temperature from the sun over the last 125 years has, again, had a very negligible effect.

What about volcanoes?

Volcanoes are huge and pump out tons of CO2 and other greenhouse gasses during eruptions. Maybe this is what’s making the Earth warm.

Wrong again. Interestingly, volcanic eruptions have actually cooled the earth a little over the last 125 years. This is mainly from all the ash getting up into the atmosphere and effectively shading the Earth from the sun.

Well, what about all of these put together?

Looking at all of these put together paints a very clear picture that these natural factors are not causing the warming we’ve seen. But if it’s not a natural cause, it must be something we’re doing.

The question is, what is it? Our third part in this series will look into that.
