Earth has officially crossed the critical 1.5°C global warming threshold, according to two major international studies. These findings suggest the planet has entered a dangerous new phase of climate change. This phase comes with potentially catastrophic consequences for ecosystems. It also poses serious risks for human societies.
The 2015 Paris Agreement aimed to limit global warming to no more than 1.5°C above pre-industrial levels. Yet, in 2024, global temperatures surpassed this limit—a warning sign that humanity is failing to curb greenhouse gas emissions effectively.
Two independent studies, conducted by European and Canadian researchers, analyzed historical climate trends and recent temperature spikes. Both reached the same alarming conclusion: the world is now entering a long-term period where temperatures consistently exceed 1.5°C of warming.
- The European study examined historical warming trends. It found that once Earth’s temperature exceeds a certain threshold, the following 20 years also remain at that level. This suggests that, since global warming hit 1.5°C in 2024, we may have entered a prolonged period where this warming level becomes the new norm.
- The Canadian study used month-to-month data and discovered that June 2024 marked 12 consecutive months of temperatures exceeding the 1.5°C threshold. This pattern, the researchers say, indicates that Earth is on track for a long-term breach of the Paris Agreement limit.
Even if aggressive emissions reductions begin now, both studies predict that Earth will continue surpassing 1.5°C for the foreseeable future.
WHY THIS WARMING MATTERS
Scientists have long warned that exceeding 1.5°C of warming could trigger irreversible damage to the planet. Among the most concerning impacts:
- More frequent and intense heatwaves, droughts, and wildfires
- Rising sea levels threatening coastal cities and island nations
- Worsening extreme weather events, such as hurricanes and floods
- Increased pressure on ecosystems like coral reefs, forests, and marine life
- Greater risks to global food and water security
WORLD IS HEADING IN THE WRONG DIRECTION
Despite decades of warnings, humanity’s greenhouse gas emissions continue to rise. Since the first Intergovernmental Panel on Climate Change (IPCC) report in 1990, annual CO2 emissions have surged by 50%.
To halt further global warming, scientists stress that emissions must reach net zero. Even then, some climate impacts—like ocean warming and glacial melt—will persist for centuries.
If humanity hopes to reverse the damage and return below the 1.5°C mark, the planet will require “net-negative emissions”—removing more carbon from the atmosphere than we emit. This would be a monumental challenge requiring global cooperation and innovation.
CLIMATE CHANGE’S GROWING IMPACT ON DAILY LIFE
The world is already experiencing severe climate consequences:
- Australia has already warmed 1.5°C since 1910, impacting the Great Barrier Reefand worsening bushfires.
- Coastal erosion, rising seas, and extreme heat are becoming more frequent worldwide.
- Agricultural yields are under threat, increasing food insecurity in vulnerable regions.
SIGNS OF PROGRESS—BUT NOT ENOUGH
Despite the dire warnings, some positive changes are underway:
- Renewable energy is expanding rapidly.
- Fossil fuel dependence is declining in several major economies.
- Technological advancements are helping industries reduce emissions.
However, these efforts must accelerate dramatically to prevent further warming. The studies highlight the urgent need for wealthier nations to assist poorer countries in adapting to climate impacts and transitioning to sustainable economies.
A CALL TO ACTION: HUMANITY MUST ACT NOW
The latest findings serve as a stark reminder that climate action cannot wait. The world must take decisive steps to decarbonize economies, invest in clean energy, and support vulnerable communities.
There is still time to limit the damage, but delaying action will only worsen the crisis. The future of our planet—and generations to come—depends on the choices we make today.
