What Is The Change In Climate?

By climate change, I imagine you mean global climate change, such we are experiencing, presently. Both within the scientific and political communities there appears to be a consensus, we are facing one of the most important issues of this century. Based on the number of forest fires, acidification of oceans and realization of the Permian extinction are being seen as events, caused by global warming.

Scientists who study the climate, atmosphere and geology of the earth are inclined to believe the climate change is natural. Their years of study have led them to believe frequent and chaordic rapid climate changes is the rule not an exception to the rule. Variations in the earth orbital movement around the sun is an explanation for volcanic eruption, greenhouse gas concentrations and solar dimming. However, because these conditions are seen by scientists as potentially dangerous to the human beings, due the discomfort humans are experiencing from excess heat temperatures in recent years, they are looking at the what call a crisis through a new lens so to speak.

While, Scientists in climatology, geology, and atmospheric changes agree the orbit of the earth is responsible for some change, as it  has been from the beginning of time, they are beginning to blame human beings for some drastic changes considered by some to exacerbating the rapidity of a natural event.

Humans are being blamed for burning fossil fuels, which release great amounts of Carbon Monoxide (CO2) into the air and use of Methane fuels, which pour even greater amounts of  CO2 into the air. Some even suggest there will be an accumulation of frozen chunks of methane hydrate on the floor of the seas, as global warming continues to heat sea water.

Also, there exists a concern the continuation of cutting trees in the rain forests is effecting the speed of global warming and creating additional climate changes. The cutting of trees in rain forests, is disrupting  necessary hydrological cycles, which allow the earth to cool itself. The evaporation of the water through the trees leaves, can only continue, if the trees are present. Cloud formations are fed by the process of evapotranspiration, the absorption of water from the tree leaves by the cloud formations. The earth's ability to cool itself lies in the preservation of the rain forests.

These are some of the concerns related to climate changes seen as global warming. The apparent cause of climatic changes is a phenomenon  with which we are becoming familiar. The drastic changes of temperatures throughout this winter and the drastic heat of last summer are sufficient experiences to many of us to ask questions!

If you enter words (climatic changes/global warming) into your search bar you will many links to additional information on the topic of climate changes and the causes.

          A climate change is a variation in the earth's global climate or regional climates over a period of time. It basically describes the changes in the unevenness or the average atmospheric state ranging from decades to millions of years. These changes are usually caused by processes internal to the planet earth, external forces such as the sun, etc. or factors due to human activities.

          In recent years, climate change usually refers to changes in modern climate, including the average surface temperature. It is used for factors based on human causations, and climate variability for non human caused variations.

          Examples of modern climate changes are things like global warming, little ice ages, year without a summer, etc. The United Nations Framework Convention on Climate Change is currently looking after and studying the climate changes around the world. It is usually termed as the UNFCCC.

Change in climate is defined as the study that deals with the changes in climate over a longer period of time (measured, for instance, in time period ranging from a few decades to millions of years) in different scales of time, and the possible cause-effect relationships of such variations in change of climate. In the broadest sense of the term, climatic change includes all forms of variations in climate. These are calculated for different periods of time using different statistical data, but they all relate to the same geographical area and the same meteorological elements for all practical purposes. This does not, however, take into consideration the statistical nature or physical causes of the change in climatic conditions.

The major factors influencing climate change are solar activities, changes in the Earth's orbital elements over a period of time (for example, the orbit of the Earth may be eccentric, the eclipse may be oblique or there may be a precession of equinoxes), the natural internal processes of the climatic systems, changes occurring due to anthropogenic forcing, such as an increase in the levels of carbon dioxide and other greenhouse gases in the atmosphere, etc. In a narrower sense of the term, climate change may be used to denote a change that is so significant that it influences the economic, environmental and social changes that take place in an area. These are changes in the mean value of a meteorological element, for instance, the temperature or the level of precipitation in an area over a specific period of time. The time periods may be measures in units such as decades or longer.
