The supposed stable configuration of geography,
with relatively predictable
climate patterns, coastlines and icepacks in familiar locations, and clear demarcations of territorial control on land are increasingly dubious assumptions as weather

The activists say our influence on
climate is evident in «altered rainfall
patterns,» but in this they are at odds
with their fellow - activists at the ill - fated Intergovernmental Panel, whose special report on extreme weather (2012) and whose fifth and most recent (2013) Assessment Report on the
climate question find little or no evidence of a link between our industries and enterprises on the one hand and
global rainfall
patterns on the other.
Our study suggests that these
patterns may also exist in deseasonalized monthly means of the measured temperature record in the post industrial era, a period that is normally associated
with global warming and
climate change.
The double peak is the history which an unfudged Northern Hemisphere or
global temperature index would display, as well as the
pattern in solar activity meanwhile (and that in the AMO but

«The authors write that «the El Niño - Southern Oscillation (ENSO) is a naturally occurring fluctuation,» whereby «on a timescale of two to seven years, the eastern equatorial Pacific
climate varies between anomalously cold (La Niña) and warm (El Niño) conditions,» and that «these swings in temperature are accompanied by changes in the structure of the subsurface ocean, variability in the strength of the equatorial easterly trade winds, shifts in the position of atmospheric convection, and
global teleconnection

with these changes that lead to variations in rainfall and weather
patterns in many parts of the world,» which end up affecting «ecosystems, agriculture, freshwater supplies, hurricanes and other severe weather events worldwide.»»
Recent
global climate change is also likely to affect large - scale atmospheric circulation

«The authors write that North Pacific Decadal Variability (NPDV) «is a key component in predictability studies of both regional and
global climate change,»... they emphasize that given the links between both the PDO and the NPGO
with global climate, the accurate characterization and the degree of predictability of these two modes in coupled

The distribution, cyclical
pattern, rate, and extent of recent
global warming are [fully / mostly / partially / not] consistent
with natural variability in Earth's
climate.
Decadal variations in the North Pacific Gyre Oscillation are characterized by a
pattern of sea surface temperature anomalies that resemble the central Pacific El Niño, a dominant mode of interannual variability
with far - reaching effects on
global climate patterns5, 6, 7.
The widespread trend of increasing heavy downpours is expected to continue,
with precipitation becoming less frequent but more intense.13, 14,15,16 The
patterns of the projected changes of precipitation do not contain the spatial details that characterize observed precipitation, especially in mountainous terrain, because the projections are averages from multiple models and because the effective resolution of
global climate models is roughly 100 - 200 miles.
In other words, under solar or anthropogenic influence the changes in mean
climate values, such as the
global temperature, are less important than increased duration of certain
climate patterns associated say
with cold conditions in some regions and warm conditions in the other regions
As the
global temperature increases
with changing
climate, precipitation rates and
patterns are affected through a wide range of physical mechanisms.
Professor Solomon Hsiang and colleagues described in the journal Nature in 2011 how they had investigated whether anything linked «planetary - scale

As
global warming changes many
climates and habitats throughout Europe,
with wetter and warmer conditions favouring the mosquito and its aquatic larva, the authors have modelled many
climate patterns.
The most likely candidate for that climatic variable force that comes to mind is solar variability (because I can think of no other force that can change or reverse in a different trend often enough, and quick enough to account for the historical climatic record) and the primary and secondary effects associated
with this solar variability which I feel are a significant player in glacial / inter-glacial cycles, counter climatic trends when taken into consideration
with these factors which are, land / ocean arrangements, mean land elevation, mean magnetic field strength of the earth (magnetic excursions), the mean state of the
climate (average
global temperature), the initial state of the earth's
climate (how close to interglacial - glacial threshold condition it is) the state of random terrestrial (violent volcanic eruption, or a random atmospheric circulation / oceanic
pattern that feeds upon itself possibly) / extra terrestrial events (super-nova in vicinity of earth or a random impact) along
with Milankovitch Cycles.
A change in ocean heat content can also alter
patterns of ocean circulation, which can have far - reaching effects on
global climate conditions, including changes to the outcome and
pattern of meteorological events such as tropical storms, and also temperatures in the northern Atlantic region, which are strongly influenced by currents that may be substantially reduced
with CO2 increase in the atmosphere.
Regional circulation
patterns have significantly changed in recent years.2 For example, changes in the Arctic Oscillation can not be explained by natural variation and it has been suggested that they are broadly consistent
with the expected influence of human - induced
climate change.3 The signature of
global warming has also been identified in recent changes in the Pacific Decadal Oscillation, a
pattern of variability in sea surface temperatures in the northern Pacific Ocean.4
ECMWF's approach to reanalysis combines measurements of temperature and other meteorological variables
with a
global weather model to provide a complete picture of the regional

Over the Pacific Ocean, the PDO and NPGO are the two dominant
climate modes and they are associated
with global signatures and distinct spatial
patterns of sea level changes.
There is a spatial
pattern of
climate warming independent of mean
global temperature that is consistent
with greenhouse warming.
According to the NOAA
Climate Prediction Center, the U.S. government agency tasked
with monitoring, assessing and predicting the El Niño Southern Oscillation, or ENSO, cycle (El Niño and La Niña), current
global atmospheric circulation and precipitation
patterns are consistent
with ENSO - neutral conditions in the tropical Pacific.
But don't you think there are some underlying
patterns in the
global climate that can be understood even
with greatly simplified models?
From what I can gather,
climate models now do a rather good job of predicting (or retrodicting)
global climate patterns and a plausible job for regional
patterns,
with the glaring exception of Arctic sea ice.
This criticism is best answered
with a quote from Hansen et al. (2006)-LRB-[4] p. 11): «The
pattern of
global warming has assumed expected characteristics...», confirming the maturity of
climate research.
Spatial and temporal
patterns of
global NDVI trends: correlations
with climate and human factors
Further affirmation of the reality of the warming is its spatial distribution, which has largest values at locations remote from any local human influence,
with a
global pattern consistent
with that expected for response to
global climate forcings (larger in the Northern Hemisphere than the Southern Hemisphere, larger at high latitudes than low latitudes, larger over land than over ocean).
