Page Contents - Causes of Climate Change The causes of climate change can be divided into two categories-those that are due to natural causes and those that are created by man. Natural causes There are a number of natural factors responsible for climate change. Some of the more prominent ones are continental drift, volcanoes, ocean currents, the earth's tilt, and comets and meteorites. Let's look at them in a little detail.

- Global warming is causing climate change. This has many effects. It will make the earth's atmosphere very hot causing colder climates to melt, this is a real problem for some parts of the world.lobal warming, by itself, is not harmful to the environment. It is essential for life to exist. What is harmful is EXCESSIVE global warming. This can disrupt weather patt … erns and lead to climate and weather changes which may become detrimental should they go beyond certain limits.

The extra carbon dioxide is causing global warming, which is causing climate change.his is caused by an increase in atmospheric carbon dioxide levels, resulting principally from our use of fossil fuels such as coal, oil and natural gas, and from the manufacture of cement and deforestation.

Time for change The drastic increase in the emission of CO2 (carbon dioxide) within the last 30 years caused by burning fossil fuels has been identified as the major reason for the change of temperature in the atmosphere (click the following link for a summary and graphs about the cause and effects of global warming).

Scientists collect climate change data from Irene flooding Increasing greenhouse gases – like carbon dioxide – in the atmosphere are thought to be contributing to climate change. Scientists collect Hurrican Irene water data.

- Modern climate change is dominated by human influences, which are now large enough to exceed the bounds of natural variability. The main source of global climate change is human-induced changes in atmospheric composition. These perturbations primarily result from emissions associated with energy use, but on local and regional scales, urbanization and land use changes are also important.

Population dynamics and climate change: what are the links? However, the principle cause of climate change is high consumption by people in developed countries where population growth has been low or negative. At national the level, therefore, there is a lack of association between growth of greenhouse gas emissions and growth of populations during the last century.t is politically and ethically important that any discussion of the links between the two recognizes that Northern countries with low population growth are overwhelmingly responsible for climate change, and that Southern countries with high population growth have so far contributed very little to climate change.

- Scientists know that recent climate change is largely caused by human activities from an understanding of basic physics, comparing observations with models, and fingerprinting the detailed patterns of climate change caused by different human and natural influences.

Attribution of recent climate change Carbon dioxide is the primary greenhouse gas that is contributing to recent climate change. CO2 is absorbed and emitted naturally as part of the carbon cycle, through plant and animal respiration, volcanic eruptions, and ocean-atmosphere exchange.

Attribution of recent climate change The Intergovernmental Panel on Climate Change (IPCC) reported in 2014 that scientists were more than 95% certain that global warming is mostly being caused by human (anthropogenic) activities, mainly increasing concentrations of greenhouse gases such as carbon dioxide (CO2).

- Back to Top. Factors. Greenhouse Gases. The increase in greenhouse gases caused by human activity is often cited as one of the major causes of global warming. These greenhouse gases reabsorb heat reflected from the Earth's surface, thus trapping the heat in our atmosphere.

BU Today What was new was that we were able, using the same set of data, to also test alternative hypotheses that other people hadn’t looked at.”. One hypothesis suggests that global warming is the result of what’s called internal climate variability, or changes in the interactions between the oceans and the atmosphere. In this case, it’s suggested, temperatures are rising because they are drawing heat from deep within the oceans. That can certainly happen, he says, pointing to El Niño, a warming of the waters in the equatorial Pacific that affects climate around the world.

Causes of climate change Causes of climate change. Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down rainforests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.

- Most climate scientists agree the main cause of the current global warming trend is human expansion of the greenhouse effect 1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping.

How We Know Global Warming is Real The Science Behind Human-induced Climate Change. Atmospheric carbon dioxide concentrations are higher today than at any time in at least the past 650,000 years. They are about 35% higher than before the industrial revolution, and this increase is caused by human activities, primarily the burning of fossil fuels. Carbon dioxide is a greenhouse gas, as are methane, nitrous oxide, water vapor, and a host of other trace gases. They occur naturally in the atmosphere. Greenhouse gases act like a blanket for infrared radiation, retaining radiative energy near the surface that would otherwise escape directly to space.

That Humans Are Causing Climate Change Computer models show that increased levels of human produced greenhouse gases will cause global warming and other climate changes. Although these climate models are uncertain about how much future warming will occur and how it will affect the climate, they all agree that, to some degree, these changes will happen.

What is the most important cause of climate change? Of these, the two factors relevant on timescales of contemporary climate change are changes in volcanic activity and changes in solar radiation. In terms of the Earth’s energy balance, these factors primarily influence the amount of incoming energy.

Global Warming Causes Global warming is primarily a problem of too much carbon dioxide (CO2) in the atmosphere—which acts as a blanket, trapping heat and warming the planet. As we burn fossil fuels like coal, oil and natural gas for energy or cut down and burn forests to create pastures and plantations, carbon accumulates and overloads our atmosphere.

Climate change Climate is influenced by a multitude of factors that operate at timescales ranging from hours to hundreds of millions of years. Many of the causes of climate change are external to the Earth system. Others are part of the Earth system but external to the atmosphere. Still others involve interactions between the atmosphere and other components of the Earth system and are collectively described as feedbacks within the Earth system.

- The science community now generally agrees that the Earth’s climate is undergoing changes in response to natural variability, including solar variability, and increasing concentrations of greenhouse gases and aerosols.urthermore, because of warmer temperatures, more precipitation is falling as rain rather than snow. One expected effect of climate change will be an increase in precipitation intensity: a larger proportion of rain will fall in a shorter amount of time than it has historically.
