New Delhi: Earth’s climate is increasingly growing unstable, with seven of 16 key indicators reaching record extremes, even as the world makes progress in switching to cleaner energy, a new report has warned.
Published in the journal BioScience, the seventh annual State of the Climate report said that rising greenhouse gas emissions, melting ice and warming oceans are pushing the planet into increasingly dangerous territory. The authors emphasized that the rapid destabilization of the Earth's climate system is a diagnosis of the present rather than a warning for the future. The study was co-led by William Ripple, professor emeritus at Oregon State University, and Christopher Wolf, a scientist with Terrestrial Ecosystems Research Associates.
The research tracked 16 indicators covering greenhouse gases, global temperatures, ice loss, ocean conditions, energy use and deforestation. Atmospheric carbon dioxide exceeded 428 parts per million in May 2026, which is roughly 50% above pre-industrial levels. Meanwhile, fossil fuel consumption rose by 0.9% in 2025, with oil, coal and gas use all touching record highs. Furthermore, annual carbon dioxide emissions from energy-related activities crossed 41 billion tonnes for the first time.
Naturally, the pace of global warming appears to be accelerating. Temperatures rose by around 0.36 degrees Celsius per decade between 2010 and 2024, compared with about 0.05 degrees per decade between 1880 and 1970. Glacier thickness and Greenland’s ice mass are currently at record lows, while ocean heat content and sea levels are reaching new highs. The researchers warn that climate change is intensifying pressures on food supplies, freshwater, biodiversity and human health, while increasing the risk of crossing environmental tipping points that would be extremely difficult to reverse.
Amid the grim findings, the report also pointed out a silver lining. Low-carbon sources supplied around 43% of global electricity in 2025, while solar and wind energy consumption grew by approximately 18%. For the first time in more than a century, renewable energy sources also surpassed coal in global electricity generation. Christopher Wolf noted that the world may be witnessing the emergence of the "Age of Electricity" given these low-carbon contributions.
However, growing overall energy demand means renewable energy has not yet displaced fossil fuels at the scale required. The researchers recommended combining emission cuts with measures such as restoring mangroves and wetlands, improving urban cooling, conserving water, and strengthening food and energy systems against extreme weather. They also stressed that poorer countries and small island nations, which have contributed relatively little to historical emissions, are bearing disproportionately severe consequences. The report concluded that the future is not predetermined, and faster action on emissions, ecosystem protection and adaptation could still help limit climate risks and build a more resilient world.
