Numerous urgent environmental issues facing the world today require quick attention and action. The top 15 environmental issues of 2025, which range from plastic pollution and biodiversity loss to disasters brought on by climate change, clearly demonstrate the pressing need for adaptation and mitigation.<\/p>\n
With the worldwide average temperature 0.12C higher than 2023, the previous warmest calendar year on record, 2024 was recently verified as the hottest year in history following several months of benchmark-breaking temperatures, the hottest summer ever, and the hottest day on record.<\/p>\n
<\/p>\n
In addition to being the first calendar year to surpass 1.5C over pre-industrial levels, the average world temperature was 1.60C higher than pre-industrial levels.<\/p>\n
This wraps up a decade of unprecedented heat globally fuelled by human activities, with each of the past ten years (2015-2024)\u00a0being one of the ten warmest years on record.<\/p>\n
Moreover, greenhouse gas (GHG) concentrations have never been so high. Atmospheric concentrations of all three major planet-warming gases \u2013 carbon dioxide (CO2), methane, and nitrous oxide \u2013 reached new highs in 2023, committing the planet to rising temperatures for many years to come.<\/p>\n
This is undoubtedly one of the biggest environmental problems of our lifetime: as greenhouse gas emissions blanket the Earth, they trap the sun\u2019s heat, leading to global warming.<\/p>\n
The primary source of greenhouse gas emissions worldwide is the burning of coal, natural gas, and oil for heat and power. These are the main causes of global warming because they increase the temperature of the Earth’s surface by trapping heat in the atmosphere.<\/p>\n
Global temperatures are rising quickly and steadily due to increased greenhouse gas emissions, which is causing catastrophic events worldwide. For example, Australia and the US are experiencing some of the most destructive bushfire seasons ever, locusts are swarming across parts of Africa, the Middle East, and Asia, destroying crops, and Antarctica is experiencing a heatwave that saw temperatures rise above 20C for the first time.<\/p>\n
Global temperatures will still climb in the upcoming years, even if all greenhouse gas emissions are\u00a0stopped right once. We must thus begin immediately to phase out our fossil fuels as quickly as feasible, invest in renewable energy sources, and substantially reduce emissions.
