Climate Change: The Defining Crisis of Our Time | VibePedia

Climate change refers to the long-term warming of the planet due to an increase in average global temperatures, primarily caused by human activities such as burning fossil fuels, deforestation, and land-use changes, which release large amounts of greenhouse gases like carbon dioxide and methane into the atmosphere. The consequences of climate change are far-reaching, from more frequent and severe weather events like hurricanes, droughts, and wildfires, to rising sea levels, melting glaciers, and altered ecosystems. According to NASA, the past four years have been the hottest on record, with 2020 being the hottest year ever recorded, at 1.02°C above the 1961-1990 average. The Intergovernmental Panel on Climate Change (IPCC) warns that in order to limit global warming to 1.5°C above pre-industrial levels, global carbon emissions must be cut by 45% by 2030 and reach net-zero by 2050. Climate change is a highly contested topic, with some arguing that its effects are being exaggerated, while others claim that not enough is being done to address the crisis. As the world's top climate scientists and leaders convene to discuss the issue, one thing is clear: the window for action is rapidly closing, and the consequences of inaction will be catastrophic, with the World Health Organization (WHO) estimating that between 2030 and 2050, climate change will cause approximately 250,000 additional deaths per year, mainly due to malnutrition, malaria, diarrhea, and heat stress.
