Reading Comprehension

Passage: Climate change represents one of the most pressing challenges facing humanity in the twenty-first century. Rising global temperatures have led to unprecedented changes in weather patterns, causing more frequent and severe droughts, floods, and storms. The scientific consensus is clear: human activities, particularly the burning of fossil fuels and deforestation, are the primary drivers of this phenomenon. The Intergovernmental Panel on Climate Change has warned that without significant reductions in greenhouse gas emissions, global temperatures could rise by more than 1.5 degrees Celsius above pre-industrial levels by 2030, leading to catastrophic consequences for ecosystems and human societies alike. While some progress has been made through international agreements like the Paris Accord, many experts argue that current commitments are insufficient to prevent the worst effects of climate change. The transition to renewable energy sources, sustainable agriculture, and conservation efforts are seen as critical steps toward mitigating the crisis. Question: What is the main idea of the passage?
