Is Earth’s Climate Changing? — Passage and Quiz

For decades, scientists have been studying Earth’s climate to understand patterns and changes over time. One key aspect of this research is the analysis of global temperature records. These records provide valuable insights into long-term climate trends and variations.

The global temperature record is compiled from data collected by thousands of weather stations around the world. These stations measure temperature at various locations and times, providing a comprehensive view of Earth’s climate. By analyzing this data, scientists can track changes in temperature patterns over months, years, and even centuries.

One striking finding from the global temperature record is the trend of rising temperatures in recent decades. Since the late 19th century, Earth’s average surface temperature has been steadily increasing. This phenomenon, known as global warming, is primarily attributed to human activities such as the burning of fossil fuels and deforestation, which release greenhouse gases into the atmosphere.

The consequences of rising temperatures are profound and far-reaching. They include melting ice caps, rising sea levels, more frequent and severe weather events, and shifts in ecosystems and biodiversity. These impacts underscore the urgent need for mitigation efforts to address climate change and its associated risks.
