2023 has been declared the hottest year on record by European agency Copernicus, which monitors climate data. The average temperature increase was almost 1.5°C above pre-industrial levels, a significant jump. Several factors contributed to this record-breaking heat. Elevated greenhouse gas emissions, primarily carbon dioxide, played a major role, trapping heat in the Earth's atmosphere. Additionally, natural climate patterns like El Niño and La Niña influenced regional temperatures and weather events. The consequences of this extreme heat are far-reaching. It leads to more frequent and severe weather events, including heatwaves, droughts, wildfires, and intense rainfall - posing serious threats to ecosystems, agriculture, and human populations. International agreements, like the Paris Agreement, aim to limit global warming to well below 2°C above pre-industrial levels. Achieving these goals requires a collective commitment to reducing greenhouse gas emissions, transitioning to renewable energy sources, and implementing sustainable practices across various sectors. The report underscores the importance of addressing climate change promptly to mitigate its impacts and protect the planet's future.
