Why Global Temperatures Have Been Exceptionally High Since Mid-2023 ?

  • Posted on 19/04/2024

Warming Due to Greenhouse Gases

The first cause that comes to mind when analyzing global temperatures is the climate warming caused by human activities. Greenhouse gas emissions, primarily from fossil fuel combustion and industry, have had a significant impact on the Earth's climate. Since 2013, this human-induced warming has contributed to a 0.21°C increase in the planet's average temperature. Without this contribution, the record temperatures of 2023 and 2024 would not have been possible. Climatologists emphasize the importance of considering these anthropogenic emissions to understand the evolution of the global climate.

The El Niño Effect

Another major factor contributing to the exceptional temperatures of recent years is the natural phenomenon El Niño. This phenomenon, occurring every two to seven years, began in spring 2023 after two years of La Niña events, which cooled the atmosphere slightly. El Niño led to a significant increase in land temperatures, surpassing previously recorded levels. The increase in water temperature in the eastern Pacific Ocean directly impacted atmospheric temperature in a wide area of the tropics. Although the El Niño effect was classified as "moderate" for the 2023-2024 period, it significantly contributed to raising the average global temperature.

Outlook for the Future

As we continue to witness record temperatures and extreme weather events, it is crucial to recognize the urgency of taking action to mitigate climate change. Initiatives aimed at reducing greenhouse gas emissions and adapting to changing climate conditions are essential for preserving our planet and ensuring a sustainable future for generations to come.

In conclusion, the exceptionally high global temperatures since mid-2023 are the result of a combination of factors, including warming due to human activities and the effect of the natural phenomenon El Niño. Understanding these mechanisms is essential for developing effective strategies to combat climate change and preserving our planet for future generations.
