Regardless of their locations on the planet, all humans experience climate variability and change within their lifetimes. The most familiar and predictable phenomena are the seasonal cycles, to which people adjust their clothing, outdoor activities, thermostats, and agricultural practices. However, no two summers or winters are exactly alike in the...
Human societies have experienced climate change since the development of agriculturesome 10,000 years ago. These climate changes have often had profound effects on human cultures and societies. They include annual and decadal climate fluctuations such as those described above, as well as large-magnitude changes that occur over centennial to multimi...
The history of humanity—from the initial appearance of genus Homo over 2,000,000 years ago to the advent and expansion of the modern human species (Homo sapiens) beginning some 315,000 years ago—is integrally linked to climate variation and change. Homo sapiens has experienced nearly two full glacial-interglacial cycles, but its global geographical...
The Earth system has undergone dramatic changes throughout its 4.5-billion-year history. These have included climatic changes diverse in mechanisms, magnitudes, rates, and consequences. Many of these past changes are obscure and controversial, and some have been discovered only recently. Nevertheless, the history of life has been strongly influence...
An important new area of research, abrupt climate change, has developed since the 1980s. This research has been inspired by the discovery, in the ice core records of Greenland and Antarctica, of evidence for abrupt shifts in regional and global climates of the past. These events, which have also been documented in ocean and continental records, inv...
Glacial bodies larger than 50,000 km 2 (19,000 sq mi) are called ice sheets. They are several kilometers deep and obscure the underlying topography. Deglaciation occurs naturally at the end of ice ages. But the current glacier retreat is accelerated by global warming due to human-caused greenhouse gas emissions.
Aug 5, 2021 · They ranged from RCP 2.6, where there is a drastic reduction in global fossil fuel emissions and the world only heats up a little, to RCP 8.5, a world in which fossil fuel emissions are unfettered ...
