Due to climate change we may have reached the point of no return

A new study published in the journal Nature found that Humans are taking a huge risk for the future of civilization and everything on Earth, The study, developed by an international scientific commission that included more than 40 researchers from around the world, quantified “Earth system boundaries” at global and local scales for the various biophysical processes and systems that govern the state of the planet. of. For the first time, the conditions for a safe and just life for humanity on Earth have been assessed and quantified with the same control variables that assess life support conditions on Earth.

The study found that four of the nine boundaries of the Earth system have been exceeded: Climate change, loss of biodiversity, Ocean acidification I chemical pollution, This means that we are pushing the planet beyond its limits and risk causing irreparable damage to life on Earth.

Planetary health is in danger

Professor Johan Rockström, co-chair of the Earth Commission and lead author of the study, said We have now entered the Anthropocene and we are threatening the stability and resilience of the entire planet., That is why, in an unprecedented step, we are presenting quantitative data and a strong scientific basis to assess the state of our planetary health. This assessment is not limited to the stability and resilience of the Earth system, but also extends to human well-being and fairness and justice.

Professor Rockstrom, who is also the director of the Potsdam Institute for Climate Impact Research, explained that the concept of justice refers to an important goal within the study. protect persons from significant harm, With this new perspective, we seek to understand how not only to preserve the ecological balance of our planet, but also to ensure an adequate quality of life and fair treatment for all people.

New revelations from a global study

This new study draws on authoritative scientific evidence to define the biophysical conditions necessary to maintain a stable, life-sustaining (“safe”) planet. Furthermore, it analyzes how significant harm to both humans and other species can be avoided. The study follows previous efforts such as the “planetary boundary” framework, which sought to identify the cosmic conditions necessary to maintain planetary stability and protect life on Earth.

The study by Steven Ladd aims to identify boundaries within the Earth system that can ensure safety and fairness for humans. These limits focus on five critical areas that are fundamental to life and the stability of our planet. The objective is to understand what you need to do Minimize harm from changes to the Earth system and set limits to assess and manage the state of biophysical systems such as the biosphere and freshwater., Steven Ladd is a Research Fellow at the Future Earth Commission, the Australian National University and the Stockholm Resilience Centre.

The study also quantifies these limits with respect to human expansion. The authors suggest that it is important greatly reduces the effect of human expansion In order to prevent the harm caused by it and the negative consequences on humans themselves.

Human activity is pushing the planet beyond its limits

Human activities due to the use of fertilizers are causing significant changes in water flow and excessive release of nutrients into streams, while natural areas are becoming increasingly limited. These factors threaten the stability of the planet, endangering ecosystems and their vital role for humanity. An example of this is clearly exceeding the climate threshold that is considered safe and equitable: The limit for an increase of 1 °C in temperature compared to pre-industrial levels has already been passed, As a result, millions of people are already being harmed by current climate change.

the earth system is in danger

Several elements are about to pass through their zenith, and seventeen of those elements are bound to the cryosphere. it means that The planet is becoming more sensitive to change And extreme events such as floods, droughts and heat waves are more likely to occur.

Human activities are contributing to this problem. We are releasing greenhouse gases into the atmosphere, which is increasing global warming. We are also deforesting, over exploiting natural resources and polluting the environment.

If we don’t act now, the Earth system could collapse. This would have catastrophic consequences for humanity and all other life forms on the planet.

We need to take steps to reduce our impact on the environment. We need to reduce greenhouse gas emissions, protect forests, and reuse and recycle resources. We must also work to find solutions to global problems such as poverty, hunger and inequality. The future of the planet depends on us. We must act now to protect our life support system.

Here are some things we can do to reduce our impact on the environment:

  • reduce energy consumption
  • reduce water consumption
  • reduce waste production
  • discard animal products
  • Choose sustainable products
  • Support companies and organizations working to protect the environment
