Since humanity became Earth's dominant species, our influence on the planet has intensified. The term Anthropocene—used by scientists and popularized in sources like Smithsonian Magazine—captures this unprecedented era of human-driven change.
During the Carboniferous period, 300–360 million years ago, thriving plant and marine life left enormous organic deposits. Over millions of years, these transformed into coal, oil, and natural gas, the primary fuels that now power our economy.
Burning fossil fuels releases a suite of pollutants, including:
These emissions disrupt food chains, degrade air quality, and accelerate climate change.
The U.S. Environmental Protection Agency lists nitrogen oxides, methane, carbon dioxide, and fluorinated gases as the primary greenhouse gases. Their elevated concentrations trap solar heat, raising global average temperatures, melting ice caps, and expanding seawater.
Climate models predict sea‑level rise of 0.4–1.1 meters (1.3–3.6 feet) by 2100, threatening coastal communities and ecosystems. Rising temperatures also intensify desertification, alter precipitation patterns, and strain agricultural systems.
While some uncertainties remain, the evidence for human‑induced climate change is overwhelming. The Intergovernmental Panel on Climate Change (IPCC) stated in its 2013 assessment that there is a 95 % probability that global warming since 1950 is anthropogenic.
IPCC projections outline potential temperature increases over the next century and their likely impacts on global weather patterns, underscoring the urgency of mitigation and adaptation.
