“For the first time in history: the global temperature exceeded the critical threshold of 1.5°C in 2024In 2024, the global average temperature exceeded the threshold of 1.5°C from pre-industrial levels for the first time. The record warming is caused by anthropogenic changes and the El Niño phenomenon.”, — write on: unn.ua

The new data confirmed that 2024 was the first calendar year in which average temperatures exceeded the critical threshold of 1.5°C. Last year was recognized as the hottest in the history of mankind, according to the conclusion of the World Meteorological Organization (WMO).
EU Copernicus Meteorological Service:
2024 was the warmest year since scientific observations began in 1850.
The European Union’s Copernicus climate change service has temperature data for 2024: 1.6 °C above pre-industrial levels; the 2024 temperature is also estimated to be 0.12 °C above the 2023 record.
What is the reason for the temperature jump
Scientists agree that the jump in temperature was caused mainly by continued anthropogenic climate change and the El Niño weather phenomenon, which tends to increase global temperatures. But the scale and duration of the heatwave shocked many experts who had expected temperatures to drop after El Niño ended in May 2024. Instead, it remained at record levels for the rest of the year.
According to analytical data, atmospheric concentrations of carbon dioxide and methane continued to rise and reached record annual levels in 2024 of 422 parts per million (ppm) and 1,897 parts per billion (ppb), respectively.
Carbon dioxide concentrations in 2024 were 2.9 ppm higher than in 2023, and methane concentrations were 3 ppm higher.

The world’s oceans are said to have suffered the most as sea surface temperatures remained at record highs for most of 2024, damaging marine ecosystems.
The year was accompanied by extreme weather conditions on land: intense heat, a sharp reduction in polar ice caps, deadly floods and uncontrolled forest fires.
All continents broke records.
The center of South America and Mexico was boiling like never before
Mega-wildfires like the one currently burning in Hollywood have burned parts of South America, Canada and Europe. The Amazon and the Pantanal have dried up. The Sahara was flooded. Floods in Brazil and Spain inundated cities.
“This has been a year where the effects of climate change are being felt across the planet,” said David King, former chief scientific adviser to the UK government and founder of the Climate Crisis Advisory Group.
Reference
Technically, the Paris Agreement’s goal of limiting warming to below 1.5°C is calculated based on a 20-year average, so one year exceeding the threshold does not constitute a formal breach of the goal. But given the pace of warming in recent years, many scientists argue that the long-term goal of the Paris Agreement is already out of reach.
We will remind
At the COP29 summit, the EU, the US and other developed countries agreed to increase funding for climate action to $300 billion annually by 2035. A previous offer of $250 billion was rejected as insufficient.
