15 Biggest Environmental Problems of 2024
While the climate crisis has many factors that play a role in the exacerbation of the environment, some warrant more attention than others. Here are some of the biggest environmental problems of our lifetime, from deforestation and biodiversity loss to food waste and fast fashion.
1. Global Warming From Fossil Fuels
2023 was the hottest year on record, with global average temperatures at 1.46C above pre-industrial levels and 0.13C higher than the eleven-month average for 2016, currently the warmest calendar year on record. The year was marked by six record-breaking months and two record-breaking seasons.
What’s more, carbon dioxide (CO2) levels have never been so high. After being consistently around 280 parts per million (ppm) for almost 6,000 years of human civilisation, CO2 levels in the atmosphere are now well above 420 ppm, more than double what they were before the onset of the Industrial Revolution in the 19th century. According to National Oceanic and Atmospheric Administration (NOAA) Administrator Rick Spinrad, the steady annual increase is a “direct result of human activity,” mainly from the burning of fossil fuels for transportation and electricity generation but also from cement manufacturing, deforestation, and agriculture.
This is undoubtedly one of the biggest environmental problems of our lifetime: as greenhouse gas emissions blanket the Earth, they trap the sun’s heat, leading to global warming.
Increased emissions of greenhouse gases have led to a rapid and steady increase in global temperatures, which in turn is causing catastrophic events all over the world – from Australia and the US experiencing some of the most devastating bushfire seasons ever recorded, locusts swarming across parts of Africa, the Middle East and Asia, decimating crops, and a heatwave in Antarctica that saw temperatures rise above 20C for the first time. Scientists are constantly warning that the planet has crossed a series of tipping points that could have catastrophic consequences, such as advancing permafrost melt in Arctic regions, the Greenland ice sheet melting at an unprecedented rate, accelerating sixth mass extinction, and increasing deforestation in the Amazon rainforest, just to name a few.
The climate crisis is causing tropical storms and other weather events such as hurricanes, heatwaves and flooding to be more intense and frequent than seen before. However, even if all greenhouse gas emissions were halted immediately, global temperatures would continue to rise in the coming years. That is why it is absolutely imperative that we start now to drastically reduce greenhouse gas emissions, invest in renewable energy sources, and phase our fossil fuels as fast as possible.
