Earth has already crossed 7 out of 9 "red lines"
The concept of Planetary Boundaries (PB) was introduced in 2009 by scientists from the Potsdam Institute for Climate Impact Research (PIK). According to it, the Earth has nine boundaries or "red lines."
Crossing them could disrupt the stability and habitability of our planet Earth, which has remained stable for the past 12,000 years.
Now, the situation has changed!
Scientists from 29 countries have published research in Science Advances, reporting that humanity is now crossing the seventh dangerous boundary, called a "red line."
What are these "red lines"?
They're critical limits that must not be exceeded to prevent serious harm to the planet.
Here are these boundaries, with the pluses next to the ones that are already crossed:
(+) Climate change
(+) Change in biosphere integrity
(+) Novel entities (disruption of natural element cycles)
(+) Land system change (reduction of natural land)
(+) Freshwater change (depletion of freshwater resources)
(+) Modification of biogeochemical flows
(+-) Ocean acidification
Unfortunately, in 2024, we’re crossing another planetary boundary — Ocean Acidification.
These PBs we have not yet crossed:
(-) Stratospheric ozone depletion
(-) Atmospheric aerosol loading
The director of the Potsdam Institute for Climate Impact Research (PIK), Johan Rockstrom, said:
"We recognise that the planet's health ... is at such risk today that we in science must also now step up and step right out in to the uncomfortable zone and say that we are now committing ourselves to produce every year a scientific measuring of the entire health assessment - a risk assessment - across all the planetary boundaries."
This problem concerns not only scientists, but all people on planet Earth.
Therefore, it is very important for everyone to learn about the topic of climate and share information with those who are not yet aware.
