Title: Global Warming: A Crisis We Can’t Ignore
Introduction
Global warming is the long-term heating of Earth's climate system due to
human activities, primarily the emission of greenhouse gases. Unlike
natural climate fluctuations, global warming is largely driven by man-
made factors, particularly since the mid-20th century. Its effects are
widespread and growing more intense each year, threatening ecosystems,
economies, and human health. As a defining issue of the 21st century,
global warming demands immediate and sustained global action.
Understanding Global Warming
At its core, global warming refers to the gradual increase in the Earth’s
average surface temperature. While Earth has experienced temperature
shifts in the past, the current rate of warming is unprecedented. Scientists
agree that human activities—especially the burning of fossil fuels like coal,
oil, and gas—are the primary cause.
