2024 Marks Hottest Year On Record Amid Climate Crisis

The global climate situation continues to deteriorate, as 2024 has been marked as the hottest year ever recorded, according to the World Meteorological Organization (WMO). In a stark report released recently, researchers from the WMO cited clear signs of human-caused climate change reaching alarming levels. Over the past 12 months, the global average air temperature was found to be 1.55 degrees Celsius higher than the period from 1850 to 1900, before the mass industrialization and widespread burning of fossil fuels began. This increase surpasses the previous record set in 2023.

The Paris Climate Agreement stipulates that nations commit to maintaining the global temperature increase to below 2 degrees Celsius relative to pre-industrial levels, aiming for a limit of 1.5 degrees Celsius. While the report suggests a rising temperature increase of approximately 1.34 to 1.41 degrees Celsius, it also emphasizes the significance of tracking long-term averages rather than focusing solely on yearly data.

WMO Secretary-General Celeste Saulo elaborated on the gravity of the report, stating that “the latest report is a warning that humans are increasing risks to lives, economies, and the planet.” With only half of the world’s countries equipped with sufficient early warning systems, extreme weather events continue to wreak havoc globally.

A recent study from World Weather Attribution (WWA) highlighted the direct impact of climate change on human lives. This research demonstrated that at least 3,700 fatalities were attributed to climate-related incidents in 2024, with millions displaced. While the study analyzed only 26 weather events, it inferred that the true toll could be in the tens of thousands or even hundreds of thousands when considering nearly 200 additional extreme events, including floods and droughts.

WMO’s report also noted that the significant shift from La Niña to El Niño was another factor driving the record-high temperatures seen last year. Additionally, 2024 was marked by unprecedented ocean temperatures, with data showing that the oceans are absorbing around 90% of the excess heat generated by climate change. This has severe implications for marine ecosystems, contributing to biodiversity loss and reducing the oceans’ capacity to absorb carbon.

As ocean temperatures rise, they are also linked to an increase in the frequency of tropical storms and higher acidity levels, causing detrimental effects on marine habitats and the fishing industry. The rising sea levels associated with warmer waters pose further risks, leading to coastal flooding and contamination of groundwater resources.

In response to the urgent situation, United Nations Secretary-General Antonio Guterres urged that the goal of limiting temperature increases to 1.5 degrees Celsius is still achievable if proactive measures are embraced. “Our planet is emitting more warning signals than ever,” he noted, emphasizing the need for governments to tap into the opportunities provided by clean, renewable energy.

Recent trends indicate a significant shift toward renewable energy sources, which accounted for 30% of global electricity production in 2023. As solar and wind energy technologies grow rapidly, they offer a ray of hope. Even in the United States, which has seen rolling back of environmental regulations under former President Donald Trump’s administration, solar energy capacity has been growing robustly. By the end of last year, solar infrastructure was meeting more than 7% of the total national electricity requirements.

Francesco La Camera, Director-General of the International Renewable Energy Agency (IRENA), highlighted that the cost of renewable energy is no longer an obstacle in the transition. “The price is no longer an excuse to avoid developing these energy types,” he stated.

Despite the progress in renewable energy adoption, climate scientists, including Stephen Belcher from the UK’s national weather service, continue to stress the need for more urgent and decisive actions to mitigate climate impacts. Belcher noted that the WMO report vividly illustrates that “Earth is seriously ill,” and warned that, without significant efforts, extreme weather phenomena will worsening.
