At the current rate, global warming is projected to surpass 1.5C in about four years’ time, a new study compiled by an international team of more than 70 scientists concluded.

Human activities pushed global warming to 1.37C in 2025 as the entire climate system is continuing to heat at an accelerating rate, a new study has found.

The study, published Thursday, tracked 12 key sets of indicators of the state of the climate system. Among them was the presence of greenhouse gases, the leading cause of climate change, in the atmosphere. Greenhouse gas emissions, primarily from the burning of fossil fuels, are currently at an all-time high, the study found. However, there is evidence to suggest that emission growth of carbon dioxide, the most prevalent greenhouse gas in the atmosphere, is slowing.

Another key indicator, the Earth’s energy imbalance (EEI), has more than doubled since the 1970s and it is now at record levels. The indicator, which represents the difference between the amount of energy entering and leaving the planet, provides a crucial measure of the of the overall heating of the planet and the pace and scale of human-caused climate change.

The vast majority of the Earth’s trapped atmospheric heat – around 90% – is transferred into the world’s oceans, triggering a cascading crisis across global marine and coastal systems. This immense thermal absorption causes seawater to physically expand while simultaneously accelerating the melting of glaciers, ice sheets, and permafrost.

Consequently, global sea levels are rising at an unprecedented and accelerating pace, intensifying the danger of destructive storm surges and coastal flooding. In 2025, global mean sea level reached a record high, sitting about 23 centimeters (9 inches) higher on average than in 1901, according to the study.

This surplus oceanic energy has also caused marine heatwaves to skyrocket in frequency, severely disrupting marine ecosystems, devastating commercial fisheries, and eroding natural coastal…
