Climate Crisis Accelerates as Warming Rates Surge, Experts Warn | Ukraine news

The climate crisis is developing faster than experts expected: after excluding natural factors, such as El Niño, researchers recorded a sharp rise in the warming rate to about 0.35°C per decade. This is almost twice as much as previously observed, when the average rate hovered below 0.2°C per decade in the 1970–2015 period.

If the pace of warming in the last decade continues, it will lead to a long-term overshoot of the 1.5°C (2.7°F) limit set by the Paris Agreement, even before 2030

Experts note that the elevated heat levels in recent years amplify natural fluctuations. To better assess the human impact on temperature, scientists applied a noise-reduction method to isolate the anthropogenic influence in five major data sets that specialists use to measure global warming. In each of them, a noticeable acceleration has become evident, visible in 2013–2014.

There is now fairly broad – though not universal – consensus that in recent years there has been a noticeable acceleration of warming. However, it remains unclear what portion of the additional warming over the last decade is the result of anthropogenic climate forcing, and what is due to natural variability

Greenhouse gas emissions and air pollution also shape the overall picture: the atmospheric carbon footprint is rising, driving the planet above pre-industrial levels. At the same time, the decline of cooling sulfate aerosols, which previously dampened the warming effect, has intensified this trend. In the study, of which Hausfather is a co-author, it is also noted that the rate of warming persisted, albeit reduced in some data, at about 0.27°C per decade.

In any case, this is a significant acceleration of the warming rate. It should raise concerns as the world rapidly approaches the 1.5°C threshold later this decade

According to data, carbon reductions continue to be a key factor in future scenarios: estimates, using data from one of the datasets and the Copernicus service, suggest the world could exceed the 1.5°C threshold this year if warming does not slow. Other datasets point to a potential exceedance in 2028 or 2029. Claudie Bolye of the University of California, Santa Cruz, emphasizes that the chance of keeping warming at even 2°C above pre-industrial levels “significantly narrows” if rapid warming continues.

However, not all conclusions are unambiguous: Bolye also noted that the acceleration may prove temporary. Further observations over several years are needed to determine whether this is a lasting shift or a short-term fluctuation of natural variability. She also reminded that the strong El Niño of 1998 previously gave the impression of anomalous warming, after which there was a certain slowdown in the rate.

The next slowdown was interpreted as evidence of a pause in global warming. Ongoing monitoring over the next several years will be necessary to determine whether the accelerated warming rate observed in this study is a lasting shift or a temporary phenomenon of natural variability

Climatologists warn that exceeding the 1.5–2°C range could trigger so-called “tipping points,” which could unfold over decades and centuries. Meanwhile, contemporary forecasts are more conservative, expecting stronger heat waves and increased rainfall during storms. The World Meteorological Organization confirmed that the last three years have been the warmest on record globally.

The speed with which the Earth continues to warm ultimately depends on how quickly we cut global CO2 emissions from fossil fuels to zero

– Stefan Ramstorf

Scientists continue to warn of new overheating and dangers, while emphasizing that natural systems – such as the oceans’ and plants’ uptake of CO2 – may, over time, reduce their ability to regulate the atmosphere. In this context, the question of the leading role of socio-economic factors remains relevant: there are estimates that the richest 10% of people on the planet contribute about two-thirds of global warming, underscoring the unequal distribution of impact and responsibility.

Conclusions and Outlook

Current data indicate that rates of climate change remain high and demand immediate action from the global community. If current trends persist, the consequences – from extreme temperatures to prolonged droughts and excessive rainfall – will be felt in the near future. Therefore, it is important to consistently reduce CO2 emissions and implement adaptation solutions across various sectors of the economy to mitigate the impacts of the climate crisis and keep the temperature change within a safe range.

In this context, scientists call for careful monitoring of trends and continued independent analyses to distinguish temporary fluctuations from long-term shifts. Such efforts will help better assess the effectiveness of policies and commitments to reduce emissions and adapt to climate change.
