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.

Page Contents - Causes of Climate Change Key findings. 1  Black carbon has a much greater (twice the direct) climate impact than reported in previous assessments. 2  Black carbon ranks “as the second most important individual climate-warming agent after carbon dioxide”. 3  Cleaning up diesel engines and some wood and coal combustion could slow the warming immediately.

Causes of Global Warming: the Human impact But this has been exacerbated by human activities which have led to: 1) an increase in greenhouse gas emissions that causes heat to remain trapped within the troposphere, and 2) a decrease in ozone in the stratosphere, causing less sunlight to be absorbed by the ozone layer, resulting in a cooling of the stratosphere.

Page Contents - Causes of Climate Change Human activity--such as burning fossil fuels--causes more greenhouse gases to build up in the atmosphere. As the atmosphere thickens with more greenhouse gases, more heat is held in. Fossil fuels such as oil, coal and natural gas are high in carbon and, when burned, produce major amounts of carbon dioxide or CO2.

Causes of climate change Causes for rising emissions. 1  Burning coal, oil and gas produces carbon dioxide and nitrous oxide. 2  Cutting down forests (deforestation). 3  Increasing livestock farming. 4  Fertilisers containing nitrogen produce nitrous oxide emissions. 5  Fluorinated gases produce a very strong warming effect, up to 23 000 times greater than CO2.

- Key Points There is a scientiﬁc consensus that concentrations of greenhouse gases in the atmosphere are increasing and that this is causing global climate change. Human-driven emissions of carbon dioxide and other greenhouse gases, as well as land-use change, are the processes primarily responsible for the increase.

Why you need to care about climate change â now Global warming changes climate. Human activity – mainly burning fossil fuels and chopping down forests – has caused temperatures to rise worldwide. That’s global warming. The warmer atmosphere triggers climate change, or shifts in normal climate patterns. Such deviations can result in more severe weather.

- 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.

Time for change The increase of greenhouse gas concentration (mainly carbon dioxide) led to a substantial warming of the earth and the sea, called global warming. In other words: The increase in the man-made emission of greenhouse gases is the cause for global warming. For the effects of global warming see below.lobal warming causes by greenhouse effect. Greenhouse gases in the atmosphere (see above) act like a mirror and reflect back to the Earth a part of the heat radiation, which would otherwise be lost to space.

- Story Highlights. Scientific research indicates that climate change will cause hurricanes and tropical storms to become more intense — lasting longer, unleashing stronger winds, and causing more damage to coastal ecosystems and communities.s sea surface temperatures rise, developing storms will contain more energy. At the same time, other factors such as rising sea levels, disappearing wetlands, and increased coastal development threaten to intensify the damage caused by hurricanes and tropical storms.

Global warming vs climate change Human greenhouse gas emissions are causing global warming, which in turn is causing climate change. However, because the terms are causally related, they are often used interchangeably in normal daily communications.

Climate change Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time. Climate change may refer to a change in average weather conditions, or in the time variation of weather within the context of longer-term average conditions. Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have been identified as primary

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.

Definition of Climate Change According to the scientific experts in the field of climatology, climate change is caused by human activities that have resulted in an increased concentration of greenhouse gases in our atmosphere, including carbon dioxide, water vapor, methane, ozone, and nitrous oxide.

35 Easy Ways To Stop Global Warming In fact, in the last 50 years, the earth’s global temperature has increased by 3%. Pollution caused by the release of carbon dioxide into the air creates a blanket over the atmosphere. Global warming can cause a whole chain of events to rupture ecosystems, weather patterns, and a variety of other factors. We all play a part in our future.

Global warming Vital Signs of the Planet: Global Climate Change and Global Warming. What is the “greenhouse effect”? What is causing it? Are humans to blame? What does solar irradiance have to do with it? Answers here. Most climate scientists agree the main cause of the current global warming trend is human expansion of the greenhouse effect — warming that results when the atmosphere traps heat radiating from Earth toward space.

- While the ultimate cause of anthropogenic climate change is in the atmosphere, the oceans are nonetheless a vital factor. They do not respond passively to atmospheric changes but are a very active component of the climate system. There is an intense interaction between oceans, atmosphere and ice.

Natural and Man-Made Causes of Global Warming 4. Overpopulation: Another cause of global warming is overpopulation. Since carbon dioxide contributes to global warming, the increase in population makes the problem worse because we breathe out more carbon dioxide in the atmosphere.lobal warming is affecting many parts of the world. Due to global warming, the glaciers are melting which is causing the rise in the sea level. When the level of the sea rises, it causes danger to the people living in the low lying areas.

Global Climate Change: Evidence and Causes But scientists are in agreement, the global climate is rapidly warming and the causes are rooted in human activity. Some of clearest evidence that global climate change is indeed occuring today and is being caused by human activity comes from carbon dioxide levels in the atmosphere. Take a look at the graph below, which shows atmospheric carbon dioxide levels for the past 400,000 years:

Causes and Effects of Climate Change Essay There are two main causes of climate changes - natural causes and human activities. Natural causes have influenced the earth's climates such as volcanic eruptions, ocean current, the earth's orbital changes and solar variations. The eruptions of volcanoes cause a cooling effect on the earth.
