in regional precipitation but also because of increasing evaporation driven by global warming1 — 3.
The NAO's prominent upward trend from the 1950s to the 1990s caused large
regional changes in air temperature,
precipitation, wind and storminess, with accompanying impacts on marine and terrestrial ecosystems, and contributed to the accelerated rise
in global mean surface temperature (e.g., Hurrell 1996; Ottersen et al. 2001; Thompson et al. 2000; Visbeck et al. 2003; Stenseth et al. 2003).

in the Pacific ocean either as an El Niño and La Niña with global temperature and

in GRIP deuterium excess at 4.5 ka, and suggest that this
change in isotopes of
precipitation over central Greenland may have recorded a shift
in regional hydroclimate.
This section documents
regional changes and slow fluctuations
in atmospheric circulation over past decades, and demonstrates that these are consistent with large - scale
changes in other variables, especially temperature and
precipitation.

The same should be true for climate

regional or climates
in gridded areas are the same — which they are not as is obvious from the climate zones that exist or microclimates due to

Predicting how such feedbacks will play out

Next,
regional changes in temperature and
precipitation in the high - end and non-high-end models are examined.
Current models of climate
change include sea level rise, land degradation,
regional changes in temperature and
precipitation patterns, and some consequences for agriculture, but without modeling the feedbacks that these significant impacts would have on the Human System, such as geographic and economic displacement, forced migration, destruction of infrastructure, increased economic inequality, nutritional sustenance, fertility, mortality, conflicts, and spread of diseases or other human health consequences [135,136].
Observed
changes in regional temperature and
precipitation can often be physically related to one another.
