Sentences with phrase «including changes in ocean currents»

A number of causes have been suggested, including changes in ocean currents due to melting glaciers and volcanic activity.

Not exact matches

The main factors include solar variability, volcanic activity, atmospheric composition, the amount of sunlight reflected back into space, ocean currents and changes in the Earth's orbit.

The consensus is that several factors are important: atmospheric composition (the concentrations of carbon dioxide, methane); changes in the Earth's orbit around the Sun known as Milankovitch cycles (and possibly the Sun's orbit around the galaxy); the motion of tectonic plates resulting in changes in the relative location and amount of continental and oceanic crust on the Earth's surface, which could affect wind and ocean currents; variations in solar output; the orbital dynamics of the Earth - Moon system; and the impact of relatively large meteorites, and volcanism including eruptions of supervolcanoes.

Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)

Ideas that commonly surface include perturbations to the earth's orbit by other planets, disruptions of ocean currents, the rise and fall of greenhouse gases, heat reflection by snow, continental drift, comet impacts, Genesis floods, volcanoes, and slow changes in the irradiance of the sun.

For short term (ocean surface, existing biosphere) that is about 3 ppmv / °C, for longer term (including increasing biosphere area, changes in ocean currents) the ratio is about 8 ppmv / °C.

Hi CH There are two major factor in global climatic changes (and I consider CO2 to be a minor one, taking place below the UHI)-- direct Sun - Earth link (TSI, electromagnetic, UV and particle radiation)-- Ocean heath storage (long term integration process) and distribution (ocean currents) Views of solar scientists (including Mike Lockwood) are constrained by their 1950's hero Eugene Parker's theories, which the latest discoveries often bring into quesOcean heath storage (long term integration process) and distribution (ocean currents) Views of solar scientists (including Mike Lockwood) are constrained by their 1950's hero Eugene Parker's theories, which the latest discoveries often bring into quesocean currents) Views of solar scientists (including Mike Lockwood) are constrained by their 1950's hero Eugene Parker's theories, which the latest discoveries often bring into question.

Similarly, the spinning Earth is affected by many factors, including changes in the way the winds blow or currents in the ocean.

Other factors, including greenhouse gases, also contributed to the warming and regional factors played a significant role in increasing temperatures in some regions, most notably changes in ocean currents which led to warmer - than - average sea temperatures in the North Atlantic.

The main factors include solar variability, volcanic activity, atmospheric composition, the amount of sunlight reflected back into space, ocean currents and changes in the Earth's orbit.

The report states that climate impacts could include «significant changes in sea level, ocean currents, precipitation patterns, regional temperature and weather.»

Meridional Overturning Circulation includes the action of wind, as well as density changes through differences in temperature and salinity in order to drive the ocean currents.

The more traditional candidates included changes in ice and snow cover, ocean currents, or the pattern of wind circulation and storms.

There is no doubt that human activity can change local conditions, but on a global scale natural processes including variations in solar output and ocean currents control climatic conditions.

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.

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.

This includes long term changes in vegetation growth like moving tree lines, ice / tundra cover and deep ocean currents.

Threats to marine biodiversity in the U.S. are the same as those for most of the world: overexploitation of living resources; reduced water quality; coastal development; shipping; invasive species; rising temperature and concentrations of carbon dioxide in the surface ocean, and other changes that may be consequences of global change, including shifting currents; increased number and size of hypoxic or anoxic areas; and increased number and duration of harmful algal blooms.
