Large-scale modes of climate variability, such as the El Niño-Southern Oscillation, North Atlantic Oscillation, and Indian Ocean Dipole, show significant regional correlations with seasonal weather conditions, and are routinely forecast by meteorologi
Climate change will affect how species use space across a range of spatial scales. At large scales, some species have already experienced changes in distribution related to climate effects, and others are predicted to do so. At medium scales, changes in activity may influence rates of dispersal....
The climate of the Earth, like planetary climates in general, is broadly controlled by solar irradiation, planetary albedo and emissivity as well as its rotation rate and distribution of land (with its orography) and oceans. However, the majority of climate fluctuations that affect mankind are ...
How do humans affect the cycle? Human activities have greatlyincreased carbon dioxide levels in the atmosphere and nitrogen levels in the biosphere. Altered biogeochemical cycles combined with climate change increase the vulnerability of biodiversity, food security, human health, and water quality to a...
Oceans Air masses that travel across large bodies of water often pick up a substantial amount of water vapor. In the case of an ocean, the air mass may contain considerably more moisture when it reaches the far shore. Therefore, the climate of such coastal regions tends to be wetter; the...
