The planet is sending alarm signals that are impossible to ignore: Earth is getting closer every day to “climate chaos”.
2024 was the hottest year on record in history, possibly the warmest in the last 125,000 years.
Therefore, scientists warn that Earth is dangerously approaching “climate chaos”.
A new report reveals that 22 of the 34 key indicators of planetary health are already at record levels.
Alert for “climate chaos”: the planet’s vital signs are deteriorating
The study ‘The State of Climate 2025‘, published in the journal BioScience and led by Oregon State University, documents the continuous worsening of major climate indicators.
The concentration of greenhouse gases, the average global temperature, the extent of polar ice and glaciers, along with deforestation and biodiversity loss, show increasingly negative trends.
Additionally, fossil fuel consumption reached an all-time high last year.
Ocean heat and the loss of tree cover due to wildfires also recorded unprecedented figures.
Finally, climate disasters multiplied both in frequency and intensity during 2024 and 2025.
Deadly and costly consequences of “climate chaos”
Extreme events have left a devastating trail in recent years.
The study exemplifies with the latest floods in Texas, which caused at least 135 deaths, while the wildfires in Los Angeles generated damages exceeding 250 billion dollars.
In Southeast Asia, Typhoon Yagi also claimed the lives of more than 800 people.
“Without effective strategies, we will quickly face increasing risks that threaten to overwhelm peace, governance, and public and ecosystem health systems,” warned William Ripple, professor at Oregon State University and lead researcher of the study.
The scientist warned about the dangerous trajectory on which the planet and humanity find themselves.
Despite the critical outlook, researchers emphasize that there is still room for action.
The report highlights that every fraction of a degree of avoided warming is crucial for human and ecological well-being, even if the goal of the Paris Agreement is not reached.
Renewable energies, such as solar and wind, could supply up to 70% of the world’s electricity by 2050.
The rapid elimination of fossil fuels would represent one of the greatest contributions to mitigating climate change.
Additionally, the protection and restoration of ecosystems such as forests, wetlands, mangroves, and peatlands could remove around 10 gigatons of CO₂ emissions annually by 2050, equivalent to 25% of current emissions.
Acting now is more economical
Reducing food loss and waste, which accounts for between 8% and 10% of global emissions, along with transitioning to more plant-rich diets, can substantially decrease emissions while promoting human health and food security.
Scientists emphasize that mitigation strategies are cost-effective and urgent.
The cost of mitigating climate change is much lower than the global economic damages that its impacts could cause.
However, specialists warn that “the window is closing” and delaying action will lead to higher costs and more severe impacts.
