the NASA Reported Friday that global temperatures in 2024 surpassed the hottest record set in 2023 and was 2.30 degrees Fahrenheit –1.28°C– Above the numbers of the twentieth century (1951-1980). Carbon dioxide, methane, etc Greenhouse gases That the temperature of the trap is responsible for Global warmingas scientists concluded.
Last year, Earth’s surface was the warmest on recordAccording to US federal agency data. The new parameter comes after 15 consecutive months – from June 2023 to August 2024 – of monthly temperature records, a series of unprecedented heat.
2024 is the hottest year on record
Bill Nelson, NASA administrator, was blunt when he said: “Once again, the temperature record has been broken: 2024 was the hottest year since records began in 1880“.
“Between record temperatures and the wildfires currently threatening our facilities and workforce in California, understanding our changing planet has never been more important,” he said.
Meanwhile, Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies in New York, noted, “Records will not be broken every year, but the long-term trend is clear.” “We are already seeing the impact of heavy rainfall, heatwaves and increased risk of flooding, which will continue to worsen as emissions continue,” he added.
1.5 degrees above baseline
For more than half of 2024 Average temperatures were more than 1.5°C above baselineThe annual average, with mathematical uncertainty, may have exceeded the level for the first time.
“The Paris Agreement on climate change lays the foundation for efforts to stay below 1.5°C in the long term,” Schmidt commented. “We are halfway to reaching Pliocene-level temperatures in just 150 years,” he added.
Additionally, the NASA expert noted that to put it in perspective, temperatures during warm periods on Earth three million years ago, when sea levels were dozens of feet higher than they are today, were only about 3 degrees Celsius warmer than pre-industrial levels.
Greenhouse gases, responsible for global warming
The warming trend in recent decades is due to… Carbon dioxide, methane and other greenhouse gases Scientists concluded that this traps heat.
In 2022 and 2023, the Earth saw record increases in carbon dioxide emissions from fossil fuels, according to a recent international analysis.
The concentration of carbon dioxide in the atmosphere has risen from pre-industrial levels in the 18th century of about 278 parts per million to about 420 parts per million today.
NASA also determined that temperatures in individual years can be affected by natural climate fluctuations such as El Niño and La Niña, which alternately heat and cool the tropical Pacific Ocean.
