Japan reported that 2024 was the hottest year on record, with temperatures significantly exceeding historical averages due to climate change. The average temperature was 1.48 degrees Celsius above the 1991-2020 norms, while extreme weather events, including heavy rainfall, caused severe impacts across the nation. Japan aims for carbon neutrality by 2050 and significant emissions cuts by 2030, seeking to transition to renewable energy.
Japan’s meteorological agency unveiled on Monday that 2024 marked the hottest year on record since data collection began in 1898. The surge in average temperatures was attributed to escalating greenhouse gas emissions and climate change. Japan’s yearly average temperature from January to December was 1.48 degrees Celsius above the baseline average (1991-2020), surpassing the previous record by 0.19 degrees Celsius. Notably, summer and autumn of 2024 were the hottest observed periods, while the snowcap on Mount Fuji was notably absent for the longest recorded duration.
In a broader context, the World Meteorological Organization reported that 2024 is on track to be recognized as the warmest year globally, continuing a pattern of exceptional heat and extreme weather over the last decade. Japan’s temperature has been steadily increasing, now at a rate of approximately 1.40 degrees Celsius per century, particularly since the 1990s. Kaoru Takahashi from the Japan Meteorological Agency emphasized the significant role of climate change in this phenomenon, noting alterations in prevailing westerly winds leading to the influx of warmer air.
The announcement from Japan’s meteorological agency aligns with global trends, as other countries have also reported record-breaking high temperatures for 2024. Climate change, driven primarily by greenhouse gas emissions, has been causing abnormal weather patterns, including increased rainfall and extreme heat. In response to the growing climatic crisis, Japan strives for carbon neutrality by 2050, with targeted emissions reductions of 46% by 2030 versus 2013 levels. This comes as Japan grapples with a heavy reliance on fossil fuels for its energy, which remains a significant factor in its environmental impact.
In summary, Japan’s declaration of 2024 as the hottest year on record serves as a critical reminder of the persistent impacts of climate change. The unprecedented heat highlights the urgent need for comprehensive strategies to mitigate greenhouse gas emissions. As nations worldwide, including Japan, navigate this climate crisis, the emphasis on transitioning to renewable energy sources emerges as a paramount priority to ensure a sustainable future.
