Breaking News: A Climate Update Amid the Musk-Trump Showdown!

Ralph Keeling, director of the Scripps CO₂ Program, summed up recent news on carbon dioxide levels with a simple, poignant statement: “Another year, another record. It’s sad.”

Why is this so concerning? For the first time, CO₂ levels at NOAA’s Mauna Loa Observatory in Hawaii have surpassed 430 parts per million (ppm). The data shows a peak average of 430.2 ppm in May 2025, which is a jump from 426.7 ppm in May 2024. NOAA’s Global Monitoring Laboratory recorded an even higher average of 430.5 ppm, marking a 3.6 ppm increase from the previous year.

Charles David Keeling, Ralph’s father, began tracking CO₂ levels back in 1958. He was the first to highlight how seasonal changes affect CO₂ concentrations: they rise in May, drop during the growing season, and rise again in fall. This ongoing record became known as the Keeling Curve. NOAA started daily measurements in 1974, providing a consistent record of atmospheric CO₂.

Notably, the increase in CO₂ levels is accelerating. Recent reports indicate that in 2024, average levels rose faster than any previous year’s data. The average for the preceding 12 months shot up by 3.58 ppm from the prior year, breaking the peak set in 2016.

A study from the University of Utah published in 2023 revealed that CO₂ levels today are higher than they have been throughout human history—specifically, the highest they’ve been in at least 14 million years. Ralph Keeling indicated that CO₂ levels above 430 ppm haven’t been seen in over 30 million years. “It’s changing so fast,” he said, expressing concern about the implications for human civilization.

The urgency of the situation is underscored by a recent United Nations report. It warned that global temperatures might rise beyond 2°C (3.6°F) within the next five years if current trends continue. Australian climate authority chairman Matt Kean responded to the alarming statistics on social media, questioning what kind of climate we want to leave for future generations.

The record levels of CO₂ raise questions that go beyond climate science. They provoke thoughts on lifestyles, industry practices, and long-term sustainability. Each peak in CO₂ serves as a reminder that the Earth is changing rapidly.

As we continue to monitor these levels, it’s important to reflect on our collective choices and the legacy we wish to create.
