Climate change has always been a factor in the earth’s history, but the current pace is unprecedented.
The rapid rise in temperatures, now +1.3°C above pre-industrial levels, is accelerating catastrophic changes like the melting of polar ice caps and the disruption of global ocean currents.
Agriculture, responsible for 30% of global carbon dioxide emissions, is both a contributor to and victim of this shift, facing dire consequences if the 2°C threshold set by the Paris Agreement is crossed. If temperatures rise by another 0.7°C, we risk irreversible damage, including rising seas and reduced freshwater availability.
According to Filippo Giorgi, an expert in climate modeling and former member of the IPCC, while the situation is critical, there is still time to act. However, this window of opportunity is narrowing quickly. Global warming is causing more frequent extreme weather events, such as heatwaves, rising sea levels, and increased natural disasters. Events like the extraordinary heatwave of 2003, which should have occurred only once every few centuries, have happened six times between 2003 and 2023. As ice continues to melt at alarming rates in Greenland and other polar regions, sea levels rise, threatening to submerge coastal areas. Moreover, the collapse of global ocean circulation could drastically alter climate patterns, leading to further instability.
Agriculture, the backbone of global food security, is particularly vulnerable. While some regions face droughts and water shortages, others are dealing with unpredictable weather, storms, and floods. As Paola Favero, an environmental expert, pointed out, even resilient ecosystems like forests are losing their balance. Forests that have taken millennia to evolve are now experiencing widespread destruction, landslides, and invasive insect outbreaks. These disruptions are not just happening in tropical climates but are seen in colder regions like Siberia and Canada, where forest fires have escalated.
One of the core challenges is the disparity in how climate change affects different regions and people. While developed nations contribute the most to emissions, it’s developing countries that bear the brunt of climate-related devastation. Countries in Africa, South America, and parts of Asia are seeing their environments destroyed by economic and cultural colonialism, with forests cleared for industrial farming and meat production. Climate change is creating a new wave of “climate migrants,” individuals forced to flee their homes due to environmental collapse. As Sara Segantin, a climate activist, argues, the world’s response to this crisis has been insufficient. Investment in ecological transition remains meager compared to military spending, leaving vulnerable populations to suffer the most while wealthier nations fortify their borders.
Despite the dire situation, there is a glimmer of hope. Younger generations are increasingly aware of the severity of climate change and are pushing for solutions. However, this growing awareness must be matched with concrete political action. The tools and technologies to combat climate change exist today, but there needs to be a global, unified effort that transcends the traditional Western-centric approach to problem-solving.
The stakes are high. If global temperatures rise by 4 to 5 degrees Celsius, the planet could become virtually unrecognizable. To avoid this "leap in the dark," as Giorgi describes it, immediate action is required. A global transition to sustainable energy, more responsible agricultural practices, and policies focused on adaptation and resilience are all necessary to mitigate the damage. Humanity is not yet at the point of no return, but without swift, coordinated action, we may soon cross that line.
