A new study updates the planetary boundary frame and shows mortal conditioning are decreasingly impacting the earth and, thereby, adding the threat of driving dramatic changes in overall Earth conditions.

For over 3 billion times, the commerce between life( represented by the planetary boundary, Biosphere Integrity) and climate have controlled the overall environmental conditions on Earth. mortal conditioning, for illustration replacing nature with other land uses, changing the quantum of water in gutters and in soil, the preface of synthetic chemicals to the open terrain, and the emigration of hothouse feasts to the atmosphere all impact these relations.

It is important to respect and maintain interactions in the Earth system to resemble those that have prevailed on Earth over the past 12,000 years to ensure that human activities do not lead to dramatic changes in the state of the Earth - changes that are likely to make the earth smaller. Ability to support modern civilizations.

Planetary Boundaries and Human Influence

The nine “planetary boundaries” represent elements of the global environment that regulate the stability and living conditions of people on the planet. The extent to which the safety limits are exceeded is due to human activities affecting the components. The Planetary Boundaries Framework uses the latest science about how the Earth system works to define a “safe operating space.” for humanity by proposing limits to the extent to which human activities can influence critical processes without risking irreversible changes to the Earth conditions on which we live.

For the first time, measurements for all boundaries were presented. Six limits were exceeded, with the number of exceedances increasing for all limits except terrestrial ozone depletion. It is not enough to focus on climate on a global scale. Developing Earth system models that accurately reflect boundary interactions, particularly climate and biosphere integrity, is an urgent priority.

The study, published in the journal Science Advances, represents the third update of the framework, conducted by 29 scientists from eight different countries.

The “blood pressure” on Earth is too high

The trend towards increasing border crossings is worrying, says Katherine Richardson, professor at the Globe Institute, director of the Sustainability Science Center at the University of Copenhagen and responsible for the study:

“That Exceeding the six limits does not necessarily mean disaster will occur, but it is a clear warning sign. We can think about this when we measure our blood pressure. A blood pressure over 120/80 does not guarantee a heart attack, but it does increase the risk of it occurring. That's why we're trying to reduce it. For ourselves and our children, we must reduce the pressure on the boundaries of these six planets."

A key conclusion of the study is that there is a need for greater focus cross-border interactions:

“It is not enough to focus on human-caused climate change if we want to protect the Earth system from irreversible damage,” says Johan Rockström, director of the Potsdam Institute for Climate Impact Research (PIK) and the origin of the Framework in 2009.

"After climate change, the integrity of the biosphere is the second pillar of our planet's stability." "Our research shows that curbing global warming and maintaining a functioning biosphere for the future must go hand in hand," he added. Co-author Wolfgang Lucht, head of the Earth System Analysis Department at PIK, emphasizes

: “It is certain that the distance A large amount of energy that would otherwise be available to nature must be the cause of the loss of the be biodiversity. We therefore propose the introduction of the Human Ownership Principle of Net Primary Production (HANPP), i.e. He., biomass use, as one of two metrics when assessing human impacts on biodiversity."

Enhanced Earth System Models Needed

A world that develops within science defined boundaries is the only way to navigate our current situation with rising, potentially catastrophic risks, at the planetary scale. We already recognize this on Climate, where the Paris agreement has adopted the climate planetary boundary of holding the 1.5°C limit.Likewise, the world has accepted a planetary limit on biodiversity.

“We hope,” adds Katherine Richardson, “that this new study will serve as a wake-up call for many and raise the international community's attention to the need to limit our impact on the planet in order to preserve and protect it. “ Conditions on Earth that allow advanced human societies to thrive.
