  • History of climate change science - Wikipedia

    The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could change the climate.

  • Causes of Climate Change | Climate Change Science | US EPA

    Periods of abrupt climate change Abrupt climate change refers to sudden (on the order of decades), large changes in some major component of the climate system, with rapid, widespread effects. Abrupt or rapid climate changes tend to frequently accompany transitions between glacial and interglacial periods (and vice versa). [2] For example, a .
