Analysis: What are the causes of recent record-high global temperatures?
Carbon Brief explores four different factors that have been proposed for the exceptional warmth seen in recent years. These are:
- A strong #ElNiño event that developed in the latter part of 2023.
-Rapid declines in #sulphur dioxide emissions – particularly from international shipping and China.
-An unusual #volcanic eruption in Tonga in 2022.
-A stronger-than-expected #SolarCycle.
Carbon Brief’s analysis finds that a combination of these factors explains most of the unusual warmth observed in 2024 and half of the difference between observed and expected warming in 2023.
However, natural fluctuations in the Earth’s climate may have also played a role in the exceptional temperatures, alongside signs of declining cloud cover that may have implications for the sensitivity of the climate to human-caused emissions.
