Another principal investigator for the project, Laura Pan, senior scientist at the National Center for Atmospheric Research in Boulder, Colo., believes storm clusters over this area of the Pacific are likely to influence climate in new ways, especially as the warm ocean temperatures (which feed the storms and chimney) continue to heat up and atmospheric patterns continue to evolve.

He believes that no one has thought of combining the two theories before because it's not an intuitive idea to look at how the effects of changing patterns of ocean circulation, which occur on time scales of thousands of years, would effect global silicate weathering, which in turn controls global climate on time scales of 100s of thousands of years.

A land - ocean pattern like that above was used in a climate model to show how storm clouds could have shielded ancient Venus from strong sunlight and made the planet habitable.

In addition, global sea level can fluctuate due to climate patterns such as El Niños and La Niñas (the opposing phases of the El Niño Southern Oscillation, or ENSO) which influence ocean temperature and global precipitation patterns.

They are identifiable in sea level rise, altered rainfall patterns, retreat of Arctic sea ice, ocean acidification, and many other aspects of the climate system.

Similarly, if as a number of recent studies suggest, anthropogenic climate forcing leads to a greater tendency for the positive phase of the North Atlantic Oscillation (NAO)[or related «Arctic Oscillation» (AO)-RSB- pattern, we would expect increased baroclinicity and storminess over a substantial region of the mid-latitude North Atlantic ocean and neighboring western Europe..

The recurring wave pattern of intense rain and thunderstorms, followed by a dry phase as the force moves across the cooler Pacific Ocean occurs every 30 - 60 days, giving this atmospheric wave its unique stamp on the climate.

Not only do the vagaries of weather patterns and ocean currents make it hard to see climate changes, but the variability in what are often termed the Earth System components complicates the picture enormously.

«They were questions about how ice sheets relate to sea level, changes in the ocean, changes in the atmosphere and also changes in weather and long - term climate patterns,» says Dr Kennicutt.

«Drought years» happen on average every five years in the Amazon and are typically a result of changes to wind and weather patterns brought about by warming in the Atlantic Ocean during events of the climate phenomenon El Niño.

-- The Pacific Decadal Oscillation is a pattern of ocean - atmospheric climate variability across the mid-latitude Pacific Oocean - atmospheric climate variability across the mid-latitude Pacific OceanOcean.

The Pacific Decadal Oscillation is a pattern of ocean - atmospheric climate variability across the mid-latitude Pacific Oocean - atmospheric climate variability across the mid-latitude Pacific OceanOcean.

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.

El Niño is a recurring climate pattern defined by above - average ocean temperatures in the equatorial Pacific that affect weather patterns around the world, leading to a slight uptick in global temperatures.

... Discernible human influences now extend to other aspects of climate, including ocean warming, continental - average temperatures, temperature extremes, and wind patterns The ASA endorses the IPCC conclusions

While it is often occurring in remote regions, ongoing change with the cryosphere has impacts on people all around the world: sea level rise affects coastlines globally, billions of people rely on water from snowpack, and the diminishing sea ice that covers the Arctic Ocean plays a significant role in Earth's climate and weather patterns.

This seems to be associated with particular patterns of change in sea surface temperature in the Atlantic and Pacific oceans, a teleconnection which is well - captured in climate models on seasonal timescales.

But some ocean patterns in the climate system can persist much longer, and understanding them can help make useful predictions for regional and global averages that don't depend so much on specific weather patterns.

The first is to emphasize your point that degassing of CO2 from the oceans is not simply a matter of warmer water reducing CO2 solubility, and that important additional factors include changes in wind patterns, reduction in sea ice cover to reveal a larger surface for gas escape, and upwelling of CO2 from depths consequent to the changing climate patterns.

The assessment considered the impacts of several key drivers of climate change: sea level change; alterations in precipitation patterns and subsequent delivery of freshwater, nutrients, and sediment; increased ocean temperature; alterations in circulation patterns; changes in frequency and intensity of coastal storms; and increased levels of atmospheric CO2.

These include such actions as driving species to extinction and adding long - lived greenhouse gases to the atmosphere in ways that have few impacts now, but could disrupt climate patterns, ocean ecosystems and coastal settlements in decades to come.

Given the number of ways that things can go wrong with continued CO2 emissions (from ocean acidfication and sea level rise to simple warming, shifting precipitation patterns, release of buried carbon in perma - frost, and the possibility of higher climate sensitivities — which seem to be needed to account for glacial / inter-glacial transitions), crossing our fingers and carrying on with BAU seems nothing short of crazy to me.
