Climate Change

Climate change refers to long-term shifts in Earth's average surface temperatures and weather patterns, primarily driven by human activities since the mid-20th century. These shifts result from increased concentrations of greenhouse gases, such as carbon dioxide and methane, in the atmosphere, mainly due to burning fossil fuels like coal, oil, and gas. The changes affect global, regional, and local scales, including rising temperatures, altered precipitation, and shifts in ecosystems.

Climate change matters because it disrupts weather patterns, ecosystems, and human societies at an accelerating rate, with the planet warming faster than at any point in recorded history. Rising temperatures lead to more frequent extreme weather events, such as heatwaves, storms, droughts, and floods, while sea levels rise from melting ice, threatening coastal areas and food production. These impacts affect human health, agriculture, biodiversity, and water supplies worldwide, with disproportionate effects on vulnerable populations and regions.

People engage in collective actions such as signing petitions to urge governments and companies to reduce emissions and transition to renewable energy. Advocacy campaigns focus on policy changes, including international agreements and regulations on fossil fuels and deforestation. Public demonstrations and legal challenges also aim to influence corporate practices and enforce environmental protections.
