(NewsNibs) - Researchers have confirmed that 2023 was the warmest year on Earth since records began, with global temperatures reaching the highest levels in 125,000 years. The first three weeks of December maintained the year's unprecedented heat, averaging about 1°C above historical norms for the period. Although December's full temperature data will only be finalized and published in early 2024, the trend suggests another peak in a year of extremes. Each month from June to November set new records, culminating in an overall mean global temperature of 1.46°C above the pre-industrial average and surpassing the previous hottest year recorded in 2016 by 0.13°C.
Heatwaves and Extreme Weather Patterns Define 2023
The extraordinary heat has had palpable effects worldwide, with the Arctic undergoing significant warming and Brazil recorded temperatures reaching 44.8°C in Araçuaí. This year's tally of extreme weather events — including intense storms in Rio Grande do Sul and Piauí, heavy rainfall in Santa Catarina, and severe droughts in Rio Grande do Norte — has been partly attributed to the elevated temperatures. On November 17, the temperature variation exceeded a crucial threshold set by the Copernicus service, heightening the symbolic urgency to adhere to Paris Agreement targets.
A Warning Signal for Climate Action
Experts link the rising temperatures to both global warming and the El Niño weather pattern, warning that the oceans' heat absorption is approaching critical limits. An analysis of El Niño events over the last 120 years reveals an increase in frequency in the latter 60 years, a disturbing acceleration. Such warming not only promotes extreme weather but also perpetuates a cycle of increased evaporation and precipitation, exacerbating natural disasters. With substantial contributions from the burning of fossil fuels, deforestation, agriculture, and industrial activities, global emissions climbed by 1.2% from 2021 to 2022. The IPCC notes that if emission rates persist, temperatures could surge by 2.5°C to 3°C by the second half of the century, leading experts to caution that without urgent action, years like 2023 may become the norm rather than the exception.
The Long-Term Trend Points to Continued Warming
Despite the potential for cooler years influenced by natural phenomena such as La Niña, the overarching tendency indicates progressive warming. El Niño years, in particular, are projected to establish new temperature records. This pattern reinforces the critical need for concerted global efforts to reduce greenhouse gas emissions to mitigate the long-term impacts of climate change on the planet's weather systems, ecosystems, and human societies.
