UN - Saba:
Global climate warming is expected to exceed 1.5 degrees Celsius between 2025 and 2029 compared to pre-industrial levels. According to the United Nations, the probability of this occurring now stands at 70%.
The British Meteorological Office said in an annual climate report prepared for the UN's World Meteorological Organization that the rate of warming will remain at historically high levels, after the planet's surface temperature in 2023 and 2024 was the highest on record.
For her part, WMO Assistant Secretary-General Ko Barrett said, "We have just experienced the ten hottest years on record. Unfortunately, the WMO report shows no signs of slowing down."
The 1.5°C warming is calculated relative to the average observed between 1850 and 1900, before humans began burning coal, gas, and oil in industrial quantities, which release carbon dioxide, the greenhouse gas largely responsible for climate change.
This 1.5°C warming is the most ambitious goal of the 2015 Paris Agreement on climate change, but many climate experts now consider it unachievable because carbon dioxide emissions have not yet begun to decline and are continuing to rise.
Climate expert Peter Thorne of Minot University in Ireland commented, "This is perfectly consistent with our approach to crossing the 1.5°C threshold in the long term, in the late 2020s or early 2030s."
