There are many things in our world that affect our climate and weather patterns! Today we’re diving into the topic of climate change and how Earth’s molten core can affect it. Whether you’re on the board with trying to learn more about the impacts of global warming on our planet or just interested in the science behind climate change, you’ve come to the right place!
How does the core affect the magnetic field of the earth?
The core of Earth affects more than just our climate, it can affect the magnetic field of Earth. The rotation of the electrically conducting iron in our Earth’s core can cause electric currents which do affect the magnetic field up above. This outer shell of turbulent convection is part of everything that we know as human beings living on Earth, it helps keep us moving properly and gravity working well. There are many other ways the core affects the magnetic field of Earth but today we want to focus on how Earth’s core can affect climate or weather patterns.
Changes in Earth’s Day
One can start this conversation by discussing how Earth’s molten core impacts the changes in our daylight hours. When the daylight hours are longer, the planet will be warmer and when the daylight hours are shorter, you can predict that the Earth will have cooler temperatures. there’s more to this than just the sunshine, though.
While the core of our planet can get a bit too feisty, or hot to deal with, scientists are able to measure movement and seasonal changes. Earth’s day depends on a number of variables to include seasonal changes, interannual cycles, decadal cycles, and cycle changes that change after multiple decades have passed. One of the cycles that Earth goes through, which typically lasts 65-80 years can change the length of our planet’s day by 4 milliseconds.
All of these variables impact what type of weather patterns we experience in our everyday life and whether the climate is warming quickly or not.
Fluctuations in Temperature
The various Earth changes, cycles, and other inner changes impact our temperature by just a small number but over time we can see the impacts. For example, one study has shown researchers that variations in the length of day we experience here on Earth have shifted the temperature just 0.2 degrees celsius.
This is a measurement of the change experienced with our surface temperature.
Around 1930, a researcher was able to put three parts of the Earth’s changes into one model that showed that our climate is indeed impacted by Earth’s core and other changes, such as the natural cycles. This researcher reviewed data from 1800 forward and around the year 1930 is when researchers noticed the changes in Earth’s movement with the changes in Earth’s day happened to adjust our temperature on the planet.
This team did take into account the estimated change in climate that could be blamed on human beings and adjust the data to only reference how the Earth’s core changes and Erath’s Day changes affected climate. During their research, they found that human influence can mask the natural changes of Earth and in turn, confuse us to think that we impact the temperature changes more than we actually do.
You see, Earth has a natural heating and cooling pattern, but none of us have been around long enough to witness this dramatic change. This is why we must always be more aware of the Earth’s natural process as a living, breathing planet!
The planet has its own life-term and we’re pretty sure it’s not going to last forever. While this news that Earth’s molten core and other variable patterns do impact climate more than human beings, it’s never a bad idea to do our part to make conscious decisions to keep our planet clean and tidy!
