A new study sheds light on how humans may not simply be warming Earth, but instead may be making the planet’s climate chaotic. The new research was shared on ArXiv and is pending peer review.
The research attempts to understand human’s broad range of effects on Earth’s climate. If we don’t change our way and curb the use of fossil fossils, Earth is heading down a dark road, the study’s authors from the Department of Physics and Astronomy at the University of Porto in Portugal wrote.
Why current changes are peculiar for Earth
It’s not uncommon for Earth to experience radical changes in climate patterns – these act as stages of going from one era of stability to another. Usually, natural factors like changes in Earth’s orbit or a massive surge in volcanic activity are considered responsible for climate changes.
But we’re now entering a stage of change propelled completely by human beings. With more carbon being released into the atmosphere, for the first time ever, humans are directly changing the planet’s climate. Scientists call it the beginning of a new Anthropocene era.
The Anthropocene was introduced as phase of transition in the new study. Phase transitions in Earth’s climate will lead to unpredictable patterns of seasons and weather. This will be the cause of chaos on Earth, and the planet will experience sudden and quick changes in climate.
Do we know where Earth’s climate is headed?
This only depends on what humans do in the next few decades. If carbon output is controlled, things could be different than in a situation where nothing changes. To account for various routes humans could take, scientists used a mathematical tool called a logistic map. Based on this, scientists assumed that while our impact on climate is growing, it will eventually naturally reach a limit.
Carbon output will eventually reach its maximum level. To create this map, scientists took into account different variables like human population, potential carbon reduction strategies, and new technologies.
A best case scenario would mean that humans have hit a peak of carbon output and Earth’s climate would then begin to stabilise. On the end of this spectrum, the future of Earth’s climate looks chaotic. Seasons in the future could change from year-to-year or decade-to-decade. Weather would become extreme – from wreaking havoc in certain areas to being completely benign a moment later.
