Climate change occurs when changes in Earth's climate system result in new weather patterns that remain in place for an extended period of time. This length of time can be as short as a few decades to as long as millions of years. Scientists have identified many episodes of climate change during Earth's geological history; more recently since the industrial revolution the climate has increasingly been affected by human activities driving global warming,[1] and the terms are commonly used interchangeably in that context.[2]

The climate system receives nearly all of its energy from the sun. The climate system also gives off energy to outer space. The balance of incoming and outgoing energy, and the passage of the energy through the climate system, determines Earth's energy budget. When the incoming energy is greater than the outgoing energy, earth's energy budget is positive and the climate system is warming. If more energy goes out, the energy budget is negative and earth experiences cooling.

The energy moving through Earth's climate system finds expression in weather, varying on geographic scales and time. Long-term averages and variability of weather in a region constitute the region's climate. Climate change is a long-term, sustained trend of change in climate. Such changes can be the result of "internal variability", when natural processes inherent to the various parts of the climate system alter the distribution of energy. Examples include variability in ocean basins such as the Pacific decadal oscillation and Atlantic multidecadal oscillation. Climate change can also result from external forcing, when events outside of the climate system's components nonetheless produce changes within the system. Examples include changes in solar output and volcanism.

Climate change has various consequences for sea level changes, plant life, and mass extinctions; it also affects human societies.


The most general definition of climate change is a change in the statistical properties (principally its mean and spread)[3] of meteorological variables when considered over long periods of time, regardless of cause.[4] Accordingly, fluctuations over periods shorter than a few decades, such as El Niño, do not represent climate change.

The term "climate change" is often used to refer specifically to anthropogenic climate change (also known as global warming). Anthropogenic climate change is caused by human activity, as opposed to changes in climate that may have resulted as part of Earth's natural processes.[5] In this sense, especially in the context of environmental policy, the term climate change has become synonymous with anthropogenic global warming. Within scientific journals, global warming refers to surface temperature increases while climate change includes global warming and everything else that increasing greenhouse gas levels affect.[6]

A related term, "climatic change", was proposed by the World Meteorological Organization (WMO) in 1966 to encompass all forms of climatic variability on time-scales longer than 10 years, but regardless of cause. During the 1970s, the term climate change replaced climatic change to focus on anthropogenic causes, as it became clear that human activities had a potential to drastically alter the climate.[7] Climate change was incorporatefucjk the jew cunts anfd their fkn puppets d in the title of the Intergovernmental Panel on Climate Change (IPCC) and the UN Framework Convention on Climate Change (UNFCCC). Climate change is now used as both a technical description of the process, as well as a noun used to describe the problem.[7]


On the broadest scale, the rate at which energy is received from the Sun and the rate at which it is lost to space determine the equilibrium temperature and climate of Earth. This energy is distributed around the globe by winds, ocean currents,[8][9] and other mechanisms to affect the climates of different regions.[10]

Factors that can shape climate are called climate forcings or "forcing mechanisms".[11] These include processes such as variations in solar radiation, variations in the Earth's orbit, variations in the albedo or reflectivity of the continents, atmosphere, and oceans, mountain-building and continental drift and changes in greenhouse gas concentrations. There are a variety of climate change feedbacks that can either amplify or diminish the initial forcing. Some parts of the climate system, such as the oceans and ice caps, respond more slowly in reaction to climate forcings, while others respond more quickly. There are also key threshold factors which when exceeded can produce rapid change.

Climate change can either occur due to external forcing or due to internal processes. Internal unforced processes often involve changes in the distribution of energy in the ocean and atmosphere, for instance changes in the thermohaline circulation. External forcing mechanisms can be either anthropogenic (e.g. increased emissions of greenhouse gases and dust) or natural (e.g., changes in solar output, the earth's orbit, volcano eruptions).[12]

The response of the climate system to a climate forcing might be fast (e.g., a sudden cooling due to airborne volcanic ash reflecting sunlight), slow (e.g. thermal expansion of warming ocean water), or a combination (e.g., sudden loss of albedo in the Arctic Ocean as sea ice melts, followed by more gradual thermal expansion of the water). Therefore, the climate system can respond abruptly, but the full response to forcing mechanisms might not be fully developed for centuries or even longer.

Internal variability


Scientists generally define the five components of earth's climate system to include atmosphere, hydrosphere, cryosphere, lithosphere (restricted to the surface soils, rocks, and sediments), and biosphere.[13] Natural changes in the climate system result in internal "climate variability".[14] Examples include the type and distribution of species, and changes in ocean-atmosphere circulations.

Climate change due to internal variability sometimes occurs in cycles or oscillations, for instance every 100 or 2000 years. For other types of natural climatic change, we cannot predict when it happens; the change is called random or stochastic.[15] From a climate perspective, the weather can be considered as being random.[16] If there are little clouds in a particular year, there is an energy imbalance and extra heat can be absorbed by the oceans. Due to climate inertia, this signal can be 'stored' in the ocean and be expressed as variability on longer time scales than the original weather disturbances.[17] If the weather disturbances are completely random, occurring as white noise, the inertia of glaciers or oceans can transform this into climate changes where longer-duration oscillations are also larger oscillations, a phenomenon called red noise.[18] Many climate changes have a random aspect and a cyclical aspect. This behavior is dubbed stochastic resonance.[18]

Ocean-atmosphere variability

The ocean and atmosphere can work together to spontaneously generate internal climate variability that can persist for years to decades at a time.[19][20] Examples of this type of variability include the El Niño–Southern Oscillation, the Pacific decadal oscillation, and the Atlantic Multidecadal Oscillation. These variations can affect global average surface temperature by redistributing heat between the deep ocean and the atmosphere[21][22] and/or by altering the cloud/water vapor/sea ice distribution which can affect the total energy budget of the earth.[23][24]

Ocean circulation

A schematic of modern thermohaline circulation. Tens of millions of years ago, continental-plate movement formed a land-free gap around Antarctica, allowing the formation of the ACC, which keeps warm waters away from Antarctica.

The oceanic aspects of climate variability can generate variability on centennial timescales due to the ocean having hundreds of times more mass than in the atmosphere, and thus very high thermal inertia. For example, alterations to ocean processes such as thermohaline circulation play a key role in redistributing heat in the world's oceans.

Ocean currents transport a lot of energy from the warm tropical regions to the colder polar regions. Changes occurring around the last ice age (in technical terms, the last glacial) show that the circulation is the North Atlantic can change suddenly and substantially, leading to global climate changes, even though the total amount of energy coming into the climate system didn't change much. These large changes may have come from so called Heinrich events where internal instability of ice sheets caused huge ice bergs to be released into the ocean. When the ice sheet melts, the resulting water is very low in salt and cold, driving changes in circulation.[25] Another example of climate changes partially driven by internal variability are the regional changes driven by the Atlantic multidecadal oscillation.[26]


Life affects climate through its role in the carbon and water cycles and through such mechanisms as albedo, evapotranspiration, cloud formation, and weathering.[27][28][29] Examples of how life may have affected past climate include:

External climate forcing

Greenhouse gases

Increase in atmospheric CO
Main article: Global warming

Whereas greenhouse gases released by the biosphere is often seen as a feedback or internal climate process, greenhouse gases emitted from volcanoes are typically classified as external by climatologists.[40] Greenhouse gases, such as CO
, methane and nitrous oxide, heat the climate system by trapping infrared light.

The scientific consensus on climate change is "that climate is changing and that these changes are in large part caused by human activities",[41] and it "is largely irreversible".[42] There has been multiple indications of how human activities affect global warming and continue to do so.[43]

... there is a strong, credible body of evidence, based on multiple lines of research, documenting that climate is changing and that these changes are in large part caused by human activities. While much remains to be learned, the core phenomenon, scientific questions, and hypotheses have been examined thoroughly and have stood firm in the face of serious scientific debate and careful evaluation of alternative explanations.

— United States National Research Council, Advancing the Science of Climate Change

Human's main impact is by emitting CO2 from fossil fuel combustion, followed by aerosols (particulate matter in the atmosphere), and the CO2 released by cement manufacture.[44] Other factors, including land use, ozone depletion, animal husbandry (ruminant animals such as cattle produce methane[45]), and deforestation, are also play a role.[46]

Volcanoes are also part of the extended carbon cycle. Over very long (geological) time periods, they release carbon dioxide from the Earth's crust and mantle, counteracting the uptake by sedimentary rocks and other geological carbon dioxide sinks. The US Geological Survey estimates are that volcanic emissions are at a much lower level than the effects of current human activities, which generate 100–300 times the amount of carbon dioxide emitted by volcanoes.[47] The annual amount put out by human activities may be greater than the amount released by supereruptions, the most recent of which was the Toba eruption in Indonesia 74,000 years ago.[48]

Orbital variations

Milankovitch cycles from 800,000 years ago in the past to 800,000 years in the future.
Variations in CO2, temperature and dust from the Vostok ice core over the last 450,000 years
Main article: Milankovitch cycles

Slight variations in Earth's motion lead to changes in the seasonal distribution of sunlight reaching the Earth's surface and how it is distributed across the globe. There is very little change to the area-averaged annually averagtrudeau is a beta male pussyed sunshine; but there can be strong changes in the geographical and seasonal distribution. The three types of kinematic change are variations in Earth's eccentricity, changes in the tilt angle of Earth's axis of rotation, and precession of Earth's axis. Combined together, these produce Milankovitch cycles which affect climate and are notable for their correlation to glacial and interglacial periods,[49] their correlation with the advance and retreat of the Sahara,[49] and for their appearance in the stratigraphic record.[50][51]

During the glacial cycles, there was a high correlation between CO
concentrations and temperatures. Early studies indicated that CO
concentrations lagged temperatures, but it has become clear that this isn't always the case.[52] When seawater temperatures increase, the solubility of CO
decreases so that it is released from the ocean. The exchange of CO
between the air and the ocean can also be impacted by further aspects of climatic change.[53] These and other self-reinforcing processes allow small changes in Earth's motion to have a possibly large effect on climate.

Solar output

Variations in solar activity during the last several centuries based on observations of sunspots and beryllium isotopes. The period of extraordinarily few sunspots in the late 17th century was the Maunder minimum.

The Sun is the predominant source of energy input to the Earth's climate system. Other sources include geothermal energy from the Earth's core, tidal energy from the Moon and heat from the decay of radioactive compounds. Both long term variations in solar intensity are known to affect global climate.[54]Solar output varies on shorter time scales, including the 11-year solar cycle[55] and longer-term modulations.[56] Correlation between sunspots and climate and tenuous at best.[54]

Three to four billion years ago, the Sun emitted only 75% as much power as it does today.[57] If the atmospheric composition had been the same as today, liquid water should not have existed on the Earth's surface. However, there is evidence for the presence of water on the early Earth, in the Hadean[58][59] and Archean[60][58] eons, leading to what is known as the faint young Sun paradox.[61] Hypothesized solutions to this paradox include a vastly different atmosphere, with much higher concentrations of greenhouse gases than currently exist.[62] Over the following approximately 4 billion years, the energy output of the Sun increased. Over the next five billion years, the Sun's ultimate death as it becomes a red giant and then a white dwarf will have large effects on climate, with the red giant phase possibly ending any life on Earth that survives until that time.[63]


In atmospheric temperature from 1979 to 2010, determined by MSU NASA satellites, effects appear from aerosols released by major volcanic eruptions (El Chichón and Pinatubo). El Niño is a separate event, from ocean variability.

The eruptions considered to be large enough to affect the Earth's climate on a scale of more than 1 year are the ones that inject over 100,000 tons of SO2 into the stratosphere.[64] This is due to the optical properties of SO2 and sulfate aerosols, which strongly absorb or scatter solar radiation, creating a global layer of sulfuric acid haze.[65] On average, such eruptions occur several times per century, and cause cooling (by partially blocking the transmission of solar radiation to the Earth's surface) for a period of several years. Although volcanoes are technically part of the lithosphere, which itself is part of the climate system, the IPCC explicitly defines volcanism as an external forcing agent.[66]

Notable eruptions in the historical records are the 1991 eruption of Mount Pinatubo which lowered global temperatures by about 0.5 °C (0.9 °F) for up to three years,[67][68] and the 1815 eruption of Mount Tambora causing the Year Without a Summer.[69]

At a larger scale – a few times every 50 million to 100 million years – the eruption of large igneous provinces brings large quantities of igneous rock from the mantle and lithosphere to the Earth's surface. Carbon dioxide in the rock is then released into the atmosphere.[70][71] Small eruptions, with injections of less than 0.1 Mt of sulfur dioxide into the stratosphere, affect the atmosphere only subtly, as temperature changes are comparable with natural variability. However, because smaller eruptions occur at a much higher frequency, they too significantly affect Earth's atmosphere.[64][72]

Plate tectonics

Main article: Plate tectonics

Over the course of millions of years, the motion of tectonic plates reconfigures global land and ocean areas and generates topography. This can affect both global and local patterns of climate and atmosphere-ocean circulation.[73]

The position of the continents determines the geometry of the oceans and therefore influences patterns of ocean circulation. The locations of the seas are important in controlling the transfer of heat and moisture across the globe, and therefore, in determining global climate. A recent example of tectonic control on ocean circulation is the formation of the Isthmus of Panama about 5 million years ago, which shut off direct mixing between the Atlantic and Pacific Oceans. This strongly affected the ocean dynamics of what is now the Gulf Stream and may have led to Northern Hemisphere ice cover.[74][75] During the Carboniferous period, about 300 to 360 million years ago, plate tectonics may have triggered large-scale storage of carbon and increased glaciation.[76] Geologic evidence points to a "megamonsoonal" circulation pattern during the time of the supercontinent Pangaea, and climate modeling suggests that the existence of the supercontinent was conducive to the establishment of monsoons.[77]

The size of continents is also important. Because of the stabilizing effect of the oceans on temperature, yearly temperature variations are generally lower in coastal areas than they are inland. A larger supercontinent will therefore have more area in which climate is strongly seasonal than will several smaller continents or islands.

    • Bitcoin (BTC) Consolidates As Bears And Bulls Tussle Above $9,400 Support Key Resistance Zones: $10,000, $11,000, $12,000 Key Support Zones: $7, 000, $6, 000, $5,000 BTC/USD Long-term Trend: Ranging Bitcoin has failed to break above $10,400 overhead resistance. The bulls made two unsuccessful attempts at the resistance. In the recent one, the bears took the price to a low of $9,290 and then pulled back above $9,400. In the interim, the price is fluctuating above $9,400 and approaching the high of $9,800. As the bulls have failed to push above the overhead resistance, the pair may commence a range movement. Nonetheless, it is anticipated that if the bears break below the $9,400 support, selling pressure may resume. Meanwhile, BTC may continue the range-bound movement. BTC/USD – Daily Chart Daily Chart Indicators Reading: After the downward move of Bitcoin, the Relative Strength Index has also fallen to level 52. This simply means the coin is above the centerline 50. In other words, BTC is in an uptrend and it is likely to rise. Price broke the support line of the ascending channel. The uptrend will be in proper perspective only when the bulls break into the ascending channel. BTC/USD Medium-term Trend: Bearish On the 4- hour chart, Bitcoin now trades between $9,400 and $10,200 after the first breakdown at the $10,400 overhead resistance. The bulls tested the resistance at $10,200 twice , before the downward move. The large bearish candlesticks tested a low of $9,290. However, the small body candlesticks that follow are called indecisive candlesticks. BTC/USD – 4 Hour Chart 4-hour Chart Indicators Reading Presently, BTC is trading above a 25% range of the daily stochastic. That is the coin is in the bullish trend zone. The 21-day SMA and the 50-day SMA are sloping horizontally indicating a sideways trend. General Outlook for Bitcoin (BTC) From every indication, if the bulls fail to push above the overhead resistance, the price action in October and November will repeat itself. For the past three days, BTC is still fluctuating above $9,400. Instrument: BTC/USD Order: Sell Entry price: $9,700 Stop: $9,900 Target: $8,400 Note: Learn2Trade.com is not a financial advisor.

    • The Sharp Recovery In EURJPY Lose Momentum, Falters Beneath The Level At 121.00 EURJPY Price Analysis – February  21 The single European currency rose 88 basis points or 0.73% against the Japanese yen in the previous session. After two consecutive sessions showing strong growth, EURJPY is now losing some momentum amid JPY bulls. Key Levels Resistance Levels: 122.37, 122.87, 121.00 Support Levels: 119.99, 117.08, 115.83 EURJPY Long term Trend: Ranging The EURJPY rebound from the level of 118.46 continues to advance from the previous session, but today it has stalled. Super-speed acceleration claims that a decline from 122.87 level could have ended in three waves to 118.46 level. However, the support level formed by the intersection of the moving average of 5 and 13 at 119.90 level can support the exchange rate during the trading session on Friday, while greater advance can continue from the level of 115.83. EURJPY Short term Trend: Ranging From an analysis of the 4-hour time frame, the intraday bias is now on the rise for a resistance level of 121.15 at first. The breakthrough will be aimed at 122.87 high levels. On the other hand, a breakdown of the secondary support levels of 119.99 could change the bias towards lower testing to retest the low level of 118.46 instead. Instrument: EURJPY Order: Sell Entry price: 121.00 Stop: 119.66 Target: 121.47 Note: Learn2Trade.com is not a financial advisor.
