Climate change

is any long-term change in the statistics of weather over durations ranging from decades to millions of years. It can be manifest in changes to averages, extremes, or other statistical measures, and may occur in a specific region or for the Earth as a whole. The climate change problem is related to changes in the concentration of the greenhouse gases (water vapor, CO2, CH4, N2O, and CFCs), which trap infrared radiation from the Earth's surface and thus cause the greenhouse effect. This effect is a natural phenomenon, which helps maintain a stable temperature and climate on Earth. Human activities, such as fossil fuel combustion, deforestation, and some industrial processes have led to an increase in greenhouse gases concentration. Consequently, more infrared radiation has been captured in the atmosphere, which causes changes in the air temperature, precipitation patterns, sea-level rise, and melting of glaciers. Virtually all scientists agree that the Earth has warmed a small amount, when instrumented temperature records became reasonably accurate and distributed in key areas of the world. Now a day, I think not only me, who was observing our climate today. Our world has facing a huge problem, the people around us has been played it as a game. We are experiencing floods because of the destroyed forests, tornadoes in other countries, eruption of volcanoes, hurricane and also landslide. Some definitions of climatic extremes choose to separate the nature of the event from its social and economic consequences. When a climate extreme has an adverse impact on human welfare, it becomes a climatic disaster. Extreme weather events include droughts, floods and associated landslides, storms, cyclones and tornadoes, ocean and coastal surges, heat waves and cold snaps. There are some sure signs of climate change. 1. High global temperature- global warming is the increase of average temperature of the earths near surface air and oceans. It is common problem that are world has facing it today. We usually experience this. Scientists said. Mean temperature it is the average temperature of the air by a properly exposed thermometer during a given time period, in 1979, it increase in mean. 0.6 degree has been increase in our climate. 2. Greenhouse Gases- are gases in an atmosphere that absorb and emit radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. Methane- it is a chemical compound. Carbon dioxide, fertile fuel and current are the cause of green house gases. Biomass is a renewable energy source, biological material derived from living, such a wood, and waste and alcohol fuels. In includes also deforestations. Deforestation is logging and burning of trees. Deforestation is the permanent destruction of indigenous forests and woodlands. There are some causes of deforestation one of this is used for urban and construction purposes, it is the cutting down of trees that cause landslides and floods, this is used to construct for furniture and etc. To grow cops is a causes also they

cut trees in order to clear the land for growing crops. Trees are cut down in developing countries to be used as firewood or turned into charcoal, which are used for cooking and heating purposes. If there are causes there is also of course effects, There are a number of adverse effects of deforestation, such as: Flooding and Drought: One of the vital functions of forests is to absorb and store great amounts of water quickly when there are heavy rains. When forests are cut down, this regulation of the flow of water is disrupted, which leads to alternating periods of flood and then drought in the affected area. Loss of Biodiversity: The unique biodiversity of various geographical areas is being lost on a scale that is quite unprecedented. Erosion of Soil: When forest areas are cleared, it results in exposing the soil to the sun, making it very dry and eventually, infertile, due to volatile nutrients such as nitrogen being lost. 3. Sea level rise-Current sea level rise is due partly to human-induced global warming,[ which will increase sea level over the coming century and longer periods. Philippines is one of the vulnerable countries. In sea level rise coral bleaching is also includes. Coral bleaching is whitening of the corals. It affects fish and marines.

The general topic of climate change is the average condition. Erosion of our soil becomes the very outstanding event. El Niño, day condition, it is important temperature flections. Water is very important at all. Climate is important driver of food security we have to adapt organizations, our resources, technology and environment. Climate change may affect the health of people. We can have these diseases like malaria, dengue, typhoid fever and cholera. There is technology financing solutions. These are mitigation to lessen and adaption. Increase productivity by investing technologies. Our farmers and fisherman’s are very important. Climate change is a global challenge; it is the rise variety, drought resistant and tolerant of flooding. Methods have been developed like 4 o’clock habit the cleaning of containers in mountain groups and lower area.

Cause& effect: Natural causes: -Volcanoes eruption

-How we all, humans contribute everyday

-Earth’s tilts

-green house gases

-Ocean currents

-continental drift -human causes

Effects: -Floods& landslides

-heavier rainfall

-Changing of ecosystems

-sea level is rising

-Melting ice

-heat waves

Recommendation: As an individual I can help preventing climate change by lessen the waste we produce, electricity we use at homes, schools, office and etc, and the transportations we choose to use. Mostly, just in our own hands to make our world better. I can stop climate change by drive less, recycled more, use less hot water, plant a tree, turn off electronic devices when its not use, and change a lot. These, help us more to improved and prevent climate change, to lessen the huge problem occurring today.

Generalization The current problem in climate change is a steadily growing threat not only to the human world but also to the very existence of life in the world itself. This change in global climate is not spontaneous, but is a product of a long term consequences of human doings. A great example would be the overproduction of greenhouse gases due to machineries and factories. The increase of these gases grows incrementally over the years. This is explained through demographic observations. The amount of gases emitted to the atmosphere is directly proportional to the total human population. And since the human population is steadily rising, it would be safe to say that global warming is in sync with the increase in people. The world is suffocating from so much toxic gases being emitted by man’s machineries, and unless we do something about this problem, we might as well call it quits with Mother Nature.
