If you were to walk down the street most people would agree with you that climate change is real and are concerned about the impact of climate change on their lives. But it is a much smaller part of the population who would agree climate change is caused or changing due to human activity. In fact there will be 60% of you reading this article, or more, who will be rolling the eyes right believing there is nothing you can do and human induced climate change is all a hoax.

We’ve been told that cows farting have a large part to do with climate change because of the amount of methane they produce and that volcanoes spew out carbon having a much greater impact than any human.

 

Prepare yourself as we deep dive into the earth’s natural thermostat and why both these statements are in the most part incorrect.

(If you haven’t read a previous article ‘Earth, the only inhabitable planet in our solar system’ then we recommend you take one step back. Putting what you are about to read into context.)

Amazingly, the Earth has its own inbuilt thermostat better known as the Greenhouse Effect. If more people understood the greenhouse effect we think we’d all be in a better place to understand the impacts of humans on climate change.

The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.

The absorbed energy warms the atmosphere and the surface of the Earth. This process maintains the Earth’s temperature at around 33 degrees Celsius warmer than it would otherwise be, allowing life on Earth to exist.

It is pretty amazing.

So yes, the statement about volcanoes spewing out carbon dioxide is correct but what is incorrect about this statement is that it puts the earth’s atmosphere out of balance, contributing to climate change. Incorrect. This is a natural part of the process to keep the earth’s temperature stable.

If this makes sense, you might now be prepared to consider how does human activity influences the greenhouse effect? Because we can tell you now it doesn’t have anything to do with cows farting.
