Science questions the answers, e.g. hurricanes are caused by warm moist ocean air being drawn up into the cooler atmosphere and creating a wind pattern though we are still open to consider other factors that may have influence on this cycle.

This element moves through the atmosphere, oceans and the planet's crust in a pattern called the carbon cycle.

Regional trends are notoriously problematic for models, and seems more likely to me that the underprediction of European warming has to do with either the modeled ocean temperature pattern, the modelled atmospheric response to this pattern, or some problem related to the local hydrological cycle and boundary layer moisture dynamics.

Natural factors contributing to past climate change are well documented and include changes in atmospheric chemistry, ocean circulation patterns, solar radiation intensity, snow and ice cover, Earth's orbital cycle around the sun, continental position, and volcanic eruptions.

While not nearly as dramatic, the influence of solar, ocean, and wind patterns is much more immediate, but these effects generally alternate between warming and cooling over the course of months to decades in relation to their respective cycles.

The patterns of salinity change can be used to infer changes in the Earth's hydrological cycle over the oceans (Wong et al., 1999; Curry et al., 2003) and are an important complement to atmospheric measurements.

«They have identified human impact through phenomena such as: Transformed patterns of sediment erosion and deposition worldwide; major disturbances to the carbon cycle and global temperature; wholesale changes to the world's plants and animals; ocean acidification.

«The climate patterns responsible for the expected above - normal 2007 hurricane season continue to be the ongoing multi-decadal signal (the set of oceanic and atmospheric conditions that have spawned increased Atlantic hurricane activity since 1995), warmer - than - normal sea surface temperatures in key areas of the Atlantic Ocean and Caribbean Sea, and the El Nino / La Nina cycle»

Last summer's record loss of ice was due to a combination of natural cycle and global warming factors: «more greenhouse gases, an unusual wind pattern, and warming of the ocean water in regions with reduced sea ice.»

The papers you linked to suggest the solar cycle feeds into the internal variability of the climate due to wind and ocean current patterns.

This single pattern has a long - term global warming rate of 0.06 deg C per decade and an oscillation due to ocean cycles (http://bit.ly/nfQr92) of 0.5 deg C every 30 years as shown in the following two graphs.

Yet, we explained there is also reasonable basis for concern that a warming world may at least temporarily increase tornado damage including the fact that oceans are now warmer, and regional ocean circulation cycles such as La Nina / El Nino patterns in the Pacific which affect upper atmospheric conditions appear to becoming more chaotic under the influence of climate change.

Compare with NCEP / NCAR: Same global - scale patterns — key thing to note is patterns of equator - pole & land - ocean gradients, notably steep northern hemisphere winter western ocean boundary / eastern continent gradients — same large - scale annual cycle pattern on both animations.

Expecting less than 5 % of Earths surface to filter the air mass from the other 95 % given actual air circulation patterns is patently absurd compared to natural CO2 scrubbing mechanisms like the biological carbon cycles, or Henry's law (which is leading to ocean acidification.

E. Even the official «global temperature» record, which has been adjusted to promote global warming hysteria, has not followed the pattern of increased atmospheric concentrations of CO2, but rather has followed the pattern of natural causes, primarily solar activity and ocean cycles.

For example, every few years an ocean cycle appears in the Pacific ocean either as an El Niño and La Niña with global temperature and regional precipitation pattern changes.

Because weather patterns vary, causing temperatures to be higher or lower than average from time to time due to factors like ocean processes, cloud variability, volcanic activity, and other natural cycles, scientists take a longer - term view in order to consider all of the year - to - year changes.

The general pattern results from the superposition of various cycles related to sun activity (11 years Schwabe cycle, 22 years magnetic cycle, Wolf 90 years cycle...) and oceans» thermal oscillations (PDO, AMO, ENSO...)

Yet most research in the field has focused on improving predictions of regional ocean warming driven by long - term climate change and short - term climate patterns like the El Niño - Southern Oscillation cycle.

The latest study is based on sophisticated climate models that match the predicted impact of the great ocean - atmosphere cycles with the pattern of climate shifts recorded in the past.

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 Ccycles, 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 CyclesCycles.

But unlike those cycles, which create a standing pattern of warmth on one side of the tropical Pacific, the MJO is nearly continuous, creating a migrating cluster of storms that spawns over the western Indian Ocean and moves eastward at 15 — 30 kilometers per hour.

The inferred ocean uptake pattern shows the sum of two components: the natural carbon cycle in which CO2 is outgassed in the tropics and taken up in the extratropics, and the perturbation uptake of anthropogenic CO2.

Similar patterns are seen e.g. in the solar data, the ocean data (PDO AMO etc) and as you well know in the planetary orbits and the Milankovic cycles,.

Consider the facts: the climate system is indicated to have left the natural cycle path; multiple lines of evidence and studies from different fields all point to the human fingerprint on current climate change; the convergence of these evidence lines include ice mass loss, pattern changes, ocean acidification, plant and species migration, isotopic signature of CO2, changes in atmospheric composition, and many others.

It is one stage within a large climate pattern known the El Niño - Southern Oscillation, or ENSO, that increases and decreases the temperatures in the Pacific Ocean in somewhat predictable cycles, thereby affecting climate worldwide.

For many parts of the Americas and Asia, the occasional warming and cooling cycles in the tropical Pacific Ocean known as El Nino and La Nina are unwelcome visitors — barging in, usually with little warning, then staying for months or sometimes a year or two, bringing all kinds of baggage in the form of distorted patterns of storms and droughts, heat and cold.

As it happens for the ocean tides, numerous other natural cycles may be present in the climate system at all time scales and may produce interesting interference patterns and a complex dynamics.

Variations in ocean circulation speeds account for significant instances of climate change, changing the hydrological cycle and altering atmospheric circulation patterns as well.

My feeling on the latter, is that solar magnetic cycles affect far - UV / stratospheric / jetstream patterns and the long - term heat storage of the oceans; and that the former shorter cycles may be a stochastic resonance phenomenon entrained in the long term pattern.
