Using ice core data from Antarctica, researchers have established a new pre-industrial baseline for global warming, dating back to the period before 1700. This new method reveals that humanity has already caused 1.49°C of warming by 2023, meaning the 1.5°C threshold, a critical benchmark in climate change discussions, has effectively been reached. This updated baseline offers a more accurate measure of human-induced warming, reducing uncertainty compared to the commonly used 1850-1900 reference point. The researchers believe this new approach will provide a more robust and scientifically defensible basis for evaluating progress towards climate goals.

Humanity has warmed the planet by 1.5°C since 1700. This is a significant milestone, as it was the target set by the Paris Agreement to be reached by 2050. This means we have exceeded our climate goals decades ahead of schedule.
While it’s true that the Industrial Revolution began in the 1800s, the warming trend has accelerated significantly in recent decades. The majority of this warming has occurred in the last 60 years. This rapid temperature increase is a clear indication of the impact humans are having on the planet.
It’s important to note that the 1.5°C warming figure is based on data gleaned from air bubbles trapped in ice, which provide a record of past atmospheric conditions. This method of data collection allows scientists to understand how the Earth’s climate has changed over time.
The consequences of this warming are already being felt around the world. Rising sea levels, more frequent and intense heat waves, and changes in weather patterns are all direct results of climate change. The warming trend is also having a significant impact on ecosystems, leading to changes in plant and animal life.
While the 1.5°C target was an ambitious goal, it was a necessary one to prevent the worst consequences of climate change. The fact that we have already exceeded this target should be a wake-up call to all of us.
The need for immediate action is clear. Reducing greenhouse gas emissions, investing in renewable energy sources, and implementing adaptation measures are all crucial steps to mitigate the effects of climate change.
While it’s understandable to feel discouraged about the situation, it’s important to remember that we still have time to make a difference. We can choose to embrace sustainable practices and demand action from our leaders. We can all contribute to reducing our carbon footprint and advocating for policies that protect the environment.
The Earth is our home, and we have a responsibility to protect it for future generations. It’s time to act and ensure that we can all enjoy a healthy planet for years to come.
