Anthropogenic climate change is climate change caused by human action, either direct or indirect. This is not restricted to global warming, but also to regional changes in rainfall patterns, in the energetic level of the atmosphere (CAPE), and in atmosphericalbedo due to particulate matter. Variations in CO2, temperature and dust from the Vostok ice core over the last 400 000 years Climate change refers to the variation in the Earths global climate or regional climates over time. ... Global mean surface temperatures 1856 to 2005 Mean temperature anomalies during the period 1995 to 2004 with respect to the average temperatures from 1940 to 1980 Global warming is a term used to describe the trend of increases in the average temperature of the Earths atmosphere and oceans that... In meteorology, precipitation is any kind of water that falls from the sky as part of the weather. ... In meteorology, convective available potential energy (CAPE) is the amount of energy a parcel of air would have if lifted a certain distance vertically through the atmosphere. ...

Climatechange refers to a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer).
Climatechange may be due to natural internal processes or external forcings, or to persistent anthropogenicchanges in the composition of the atmosphere or in land use.
Climate projections are distinguished from climate predictions in order to emphasise that climate projections depend upon the emission/concentration/ radiative forcing scenario used, which are based on assumptions, concerning, e.g., future socio-economic and technological developments, that may or may not be realised, and are therefore subject to substantial uncertainty.
An understanding of natural climate variability is also a prerequisite for the early detection of anthropogenicclimatechange: anthropogenicclimate modifications can clearly be distinguished from natural climate fluctuations only if the structure of the natural fluctuations are known.
Climate models have evolved today to a level where realistic simulations of of the evolution of the future global climate can be carried out for given scenarios of future greenhouse gas emissions.
This was caused by a change in the ocean circulation.
