Our Trajectory Earth Will Continue to Warm and the Effects Will Be Profound The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions, and an increase in the wind intensity and rainfall from tropical cyclones.

History The rate of change since the mid-20th century is unprecedented over millennia. Earth’s climate has changed throughout history. Just in the last 800,000 years, there have been eight cycles of ice ages and warmer periods, with the end of the last ice age about 11,700 years ago marking the beginning of the modern climate…

The Greenhouse Effect Increasing Greenhouses Gases Are Warming the Planet Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the “greenhouse effect”1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Life on Earth depends on energy coming from the Sun. About half…

Climate change is a long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term. Changes observed in Earth’s climate since the mid-20th century are driven by human activities, particularly fossil fuel burning,…
