Climate Change can be defined as the change in the pattern of the weather, related changes in oceans, land surfaces and ice sheets, occurring over time. ("1. What Is Climate Change? | Australian Academy Of Science") Climate change more in depth is the change in the statistical description of the state of the climate system that persists for usually 30 years. The climate is currently changing mostly due to increased human activities like burning fossil fuels of coal, oil or natural gas, agriculture or land clearing. ("Understanding Climate Change | Department Of The Environment") Some of the recent changes over the years include increased ocean temperature, the melting of widespread melting of snow and ice as well as rising sea levels.

Increasing temperature is caused by heat being trapped by greenhouse gases in the Earth 's atmosphere, which causes the average temperatures to rise all around the world. ("Warmer Oceans | A Student 's Guide To Global Climate Change | US EPA") Increasing sea levels is caused by water which is being heated which then takes up more space. Each and every drop of water only expands by a little bit, but when this is multiplied by the expansion all over the entire depth of our oceans it all adds up and causes our sea levels to rise. Sea levels are also rising due to melting glaciers. ("Rising Sea Level | A Student 's Guide To Global Climate Change | US EPA") Increasing acidic levels is caused by Carbon dioxide being burned from fossil fuels being added into the atmosphere. Oceans are important in keeping our carbon cycle in balance. With carbon dioxide levels increasing in the atmosphere, the oceans begin to absorb it. Once absorbed the carbon dioxide reacts with sea water to form carbonic acid. This then causes the oceans to become more acidic. ("Increased Ocean Acidity | A Student 's Guide To Global Climate Change | US EPA") Increasing extreme whether events is caused by the temperature rising our air becomes warmer which causes more moisture evaporates into the atmosphere from land and water.

("Photosynthesis - Biology-Online Dictionary") This process can be simplified in this equation: 6CO2+12H2O+energy=C6H12O6+6O2+6H2O. It means photosynthesis is a process in which carbon dioxide (CO2), water (H2O) and light energy are utilized to synthesize an energy-rich carbohydrate like glucose (C6H12O6) and to produce oxygen (O2) as a by-product. ("Photosynthesis - Biology-Online
The equation of photosynthesis is: 6CO2 + 6H20 Þ C6H12O6 + 6O2 = = = =
Climate change describes the changes that are happening to the planet in different countries or regions (NASA, n.d.). Climate change is caused by global warming,
Climate change is the change in the “average weather” in a specific location. This can include temperature, precipitation, wind, humidity, and the different seasons. Climate change is caused by the release of carbon dioxide and other greenhouse

A. Sea level rise- The temperatures around the globe rise, the oceans start to warm up and water expands, the ice caps and glaciers start to melt, and more precipitation starts to fall falls instead of snow. These are some of the causes for sea levels rising. Recorded by the Department of Ecology, the sea levels have risen four to ten inches in the past one hundred years. When the climate changes it usually increases the oceans temperatures, causing water to expand which causes the sea level to rise by thermal expansion. When the water amount begins to take up more space. The sea level rising depends souly on the temperature of the ocean. Climate Change is also effected by ice glaciers melting over areas of land, which run off into our oceans. A big contribution to climate change and sea level rising is the melting ice masses of Antarctica and Greenland.
Climate change is when the climate is changing dramatically in time and that is caused by the greenhouse effect . greenhouse effect is when the fossil fuel is burned by humans to produces energy and when fossil fuel is burned it produces CO2 then the CO2 travels to the atmosphere and then more CO2 builds up in the atmosphere and that makes a barrier that traps the sunlight and that’s called the greenhouse effect. Usually, the sunlight stays in the earth's atmosphere for a while but then it escapes but by having more Greenhouse gases it traps it and then
“Photosynthesis (literally, “synthesis from light”) is a metabolic process by which the energy of sunlight is captured and used to convert carbon dioxide (CO2) and water (H2O) into carbohydrates (which is represented as a six-carbon sugar, C6H12O6) and oxygen gas (O2)” (BioPortal, n.d., p. 190).
Our world is always changing, so is our climate. Some changes are apparent, others not so much. Climate change is an important issue of concern in the twenty-first century. Environment, if it changes at all, evolves so slowly that the difference cannot be seen in a human lifetime (Wearth, 2014). Mostly all scientists predicted that it would take thousands of years for the planet to warm up due to emissions of carbon dioxide from fossil fuels called greenhouse gases. But in the past 200 years, things began to change. The rate and the amount of warming that is happening on this planet are unprecedented. Wearth says, “People did not grasp the prodigious fact that both population and industrialization were exploding in a pattern of exponential
In theory some parts of the world might benefit, from a human point of view, due to global warming. However, at current rates of warming, local ecosystems will collapse and any objective measure of global benefits versus suffering would show much more suffering than benefits gained.
Photosynthesis is a process in which plants and other organisms convert the light energy from the sun or any other source into chemical energy that can be released to fuel an organism’s activities. During this reaction, carbon dioxide and water are converted into glucose and oxygen. This process takes place in leaf cells which contain chloroplasts and the reaction requires light energy from the sun, which is absorbed by a green substance called chlorophyll. The plants absorb the water through their roots from the earth and carbon dioxide through their leaves.
Climate change is a long-term change in regional or global climate patterns. From the mid twentieth century to now, there has mostly been a significant increase in average global temperatures. Climate change is a major issue in the world today, and a lot of people feel very differently about the cause of it. The common argument is whether climate change is a natural occurrence or if the recent increase in temperatures is because of humans. Climate change is a natural cycle in the Earth’s weather.
As defined by the Oxford dictionary, climate change is, “a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.” (Oxford Dictionaries) Moreover, evidence of climate change can be found all over the world, and in many different forms, but is especially prevalent in certain regions. For instance, in Southeast Asia, specifically the nation of the Philippines, signs of climate change can be observed frequently, if not regularly. One major ...
Climate Change is any substantial change in climate that lasts for an extended period of time. One contributor to current climate change is global warming, which is an increase in Earth’s average temperature. Plants and animal species throughout the world are being affected by rising temperatures. Many plants are flowering earlier now than they once did; animals, such as the yellowbellied marmot, are emerging from hibernation earlier; and many bird and butterfly species are migrating north and breeding earlier in the spring than they did a few decades ago, all because of slight changes in temperature cues. (Shuster)
According to the Canada’s Action on Climate Change, Climate change is a long-term shift in weather conditions identified by changes in temperature, precipitation, winds, and other indicators. Climate change can involve both changes in average conditions and changes in variability, including, for example, extreme events. Climate change is one of the biggest crisis in the earth. It will cause a huge damage to the eco-system and human. We are the victims of the climate change. However, we are the one who cause the climate change.
Climate change is caused due to the release of few carbon compounds into the atmosphere, which drastically brought the weather changes all over the world. Climate change is not confined to a single region. It has become an important issue all over the world for the past few years.
