Climate change is what people do against nature, and the nature answers back to us. This problem is increasing in the world and the roles of people and their governments increase, too. Each country fights against climate change in their own way and because of the disasters that occur in their countries. On the other hand, we understand that the diasaters are the result of people, too.
Climate change in the world can be caused because of various activities. When climate change occurs, temperatures can increase a dramatically. When temperature rises, many different changes can occur on Earth. For example, it can result in more floods, droughts, or intense rain, as well as more frequent and severe heat waves. Oceans and glaciers have also experienced some changes: oceans are warming and becoming more acidic, glaciers are melting, and sea levels are rising. As these changes frequently occur in future decades, they will likely present challenges to our society and environment. Global warming has really increased recently. We can see that climate change is spread in many countries because of many reasons. Climate can change if there is a change in the amount of solar energy that gets to the Earth. Volcano eruptions can really affect climate.
During the past century, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere. Most of the gases come from burning fossil fuels to produce energy. Greenhouse gases are like a blanket around the Earth, trapping energy in the atmosphere and causing it to warm. This is called the greenhouse effect and it is natural and necessary to support life on earth.
Global warming has really taken effect in the world over the last century. It is the unusually rapid increase in the Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels.
The rising of temperature will have great effects on the earth’s climate patterns and on all living things. Industrial activities that our modern civilization depends upon have raised atmospheric carbon dioxide from 280 parts per million to 379 parts per million in the last 150 years (The Intergovernmental Panel on Climate Change).

Climate change is happening, it is largely caused by human activities, and it presents a serious threat to nature and people now, and in the future. Without ambitious mitigation efforts, global temperature rise this century could exceed 4 degrees Celsius above pre-industrial levels, with catastrophic impacts.
Global warming is the mainly human-caused rise of the average temperature of the Earth's climate system and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming. It is a major aspect of climate change .
Volcanic eruptions have contributed to this process ever since and provided the bulk of our atmosphere and, therefore, the climate within our atmosphere.Atmospheric reactions with volcanic gases can rapidly produce substances such as sulphuric acid that act as aerosols, cooling the atmosphere. / BORA THERESA LAZAR EDELEANU HIGH SCHOOL ROMANIA
The truth is, the climate is changing each and every day. There are many different problems that are leading to our climate change, some of them having to do with the Greenhouse Effect, and other changes are occurring due to human activity and solar irradiance.
A study by researchers in 2018 predicted that each degree of global warming will increase crop loss from insects by 10% to 25% because insect populations and their appetites surge in warm temperatures.
Volcanoes have also caused global warming over millions of years during times in Earth’s history when extreme amounts of volcanism occurred, releasing greenhouse gases into the atmosphere. / Tirnovanu Diana, Lazar Edeleanu High School,Romania
Climate change in my opinion is like a family problem and the mother of nature ,our mom, is trying to deal with it on her own and she can't control all her own problems so she's out of control and we in the same time cause her more and more problems for our own needs.So the climate change is caused by our fault and the mother of nature has her own problems and we can't communicate with her if we see only our priorities.
Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth's surface
Volcanoes can change or modify weather systems. They can cause rain, thunder and lightning.They can also have long-term effects on the climate, making their regions cooler. / Cordoneanu Stefania-Alina Lazar Edeleanu High School ,Romania.
The latest scientific data shows that the Earth's globe is warming, the climate is changing, and extreme weather events are more and more frequent: floods, drought, rising global average temperatures, rising sea levels and lowering the ice sheet - all are signs of climate change.
Melting the ice sheet due to the high temperatures due to the greenhouse effect increases the volume of oceans and seas.
Increasing their volume leads to flooding and erosion of coastal and lowland areas and this is an irreversible process that can affect human communities. / Bortă Anamaria Gabriela

Climate Change
Earth’s climate is now changing faster than at any point in the history of modern civilization, primarily as a result of human activities. Global climate change has already resulted in a wide range of impacts across every region of the country and many sectors of the economy that are expected to grow in the coming decades.
What's Happening & Why
Thousands of studies conducted by researchers around the world have documented increases in temperature at Earth’s surface, as well as in the atmosphere and oceans. Many other aspects of global climate are changing as well. Human activities, especially emissions of heat-trapping greenhouse gases from fossil fuel combustion, deforestation, and land-use change, are the primary driver of the climate changes observed in the industrial era.
Impacts on Society
Impacts related to climate change are evident across regions and in many sectors important to society—such as human health, agriculture and food security, water supply, transportation, energy, ecosystems, and others—and are expected to become increasingly disruptive in the coming decades. Thikra Shoubieta \ Jordan
Climate change is happening because of us. Human activities such as: burning fossil fuels, cutting down rainforests are releasing excessive amounts of greenhouse gases into our atmosphere, as a result. High temperatures, melting of ice on the poles, leading to sea level . ,floods , drought.. so could we save our mother earth
Global warming is primarily caused by increases in “greenhouse” gases such as Carbon Dioxide (CO2), Nitrous oxide (NOX), Sulphur dioxide (SO2), Hydrogen etc.,. A warming planet thus leads to climate changes which can adversely affect weather in different ways, recently the weather become warmer and some time colder due to those two phonemes
When volcanoes erupt, they emit a mixture of gases into the air. Some of them, such as CO2, cause warming by adding to the greenhouse effect, volcanoes are estimated to release, in total, around 100–300 million tons of CO2 each year.
Dania Aldardasawi , Queen Zain Alsharaf Secondary School- Jordan
Volcanoes are the most dramatic and rapid agents of geologic change. An erupting volcano can eject vast amounts of ash and gases into the atmosphere, and cover the ground with tons of lava flows and ash. Could it really be true that a single large volcanic eruption launches more greenhouse gases into the atmosphere than the amount generated by all of humanity over history .
This argument that human-caused carbon emissions are merely a drop in the bucket compared to greenhouse gases generated by volcanoes has been making its way around What do you think Many people think of global warming and climate change as synonyms, but scientists prefer to use “climate change” when describing the complex shifts now affecting our planet’s weather and climate systems.
Climate change encompasses not only rising average temperatures but also extreme weather events, shifting wildlife populations and habitats, rising seas, and a range of other impacts. All of these changes are emerging as humans continue to add heat-trapping greenhouse gases to the atmosphere
What do you think
•Ice is melting worldwide, especially at the Earth’s poles
•Rising temperatures are affecting wildlife and their habitats
•Hurricanes and other storms are likely to become stronger.Floods and droughts will become more common
•Some diseases will spread, such as mosquito-borne malaria. Saja Alrashaydah – st at Aqaba secondary school – Jordan

Climate change is any change in the climate, lasting for several decades or longer, including changes in temperature, rainfall or wind patterns.(Yiğit Karaman,TURKEY)
Our climate is changing quite dramatically – it’s getting hotter.Long-term air and ocean temperature records clearly show the Earth is warming. The global average temperature has already risen by 1.1°C since the pre-industrial period.(Nisa Cirdi,Turkey)
This might not sound like a lot, but 1.1°C represents a massive amount of extra heat and energy – the equivalent of four Hiroshima bomb detonations per second. (Nil Ezrak,Turkey)
While the earth’s climate has changed throughout history, scientists agree that the significant changes we’ve seen over the past hundred years or so have been due to human activities. Recent warming is also happening at a rate that is much faster than previous climatic changes.(Zeren Palta,Turkey)
Global warming has really increased recently. We can see that climate change is spread in many countries because of these reasons:
The excessive amount of greenhouse gases entering the Earth’s atmosphere due to human activity is causing our climate to change dramatically. (Miraç Utku Çetin,Turkey).
But there’s more to it than that.Let’s break it down. A certain amount of greenhouse gases (like water vapour, ozone, carbon dioxide, methane and nitrous dioxide) occur naturally. For example, carbon dioxide is produced by plants, or decaying organic matter (biomass).(Lorin Gül Bakır,Turkey).These greenhouse gases act like a blanket in our atmosphere, trapping some of the sun’s heat close to the Earth’s surface. This is known as the ‘greenhouse effect’ – and it makes the planet warm enough for us to live.(DireYıldırım,Turkey)
But since the Industrial Revolution (which began in the mid to late 1700s), greenhouse gases have built up in the atmosphere, which is trapping more heat close to the earth’s surface. This is because humans began digging up and burning coal, oil and gas, as well as scaling up agriculture and tree-clearing (deforestation), and increasing waste (landfill), which are all processes that produce greenhouse gases.(Nisa Atar,Turkey)
Climate can change if there is a change in the amount of solar energy that gets to the Earth. Volcano eruptions can really affect climate. The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation.(Berfin Oğuz,TURKEY).
The cooling effect can last for months to years depending on the characteristics of the eruption. Volcanoes have also caused global warming over millions of years during times in Earth’s history when extreme amounts of volcanism occurred, releasing greenhouse gases into the atmosphere..(Ege Sürmelioğlu,Turkey)Even though volcanoes are in specific places on Earth, their effects can be more widely distributed as gases, dust, and ash get into the atmosphere.(Atahan GENÇ,Turkey)
Because of atmospheric circulation patterns, eruptions in the tropics can have an effect on the climate in both hemispheres while eruptions at mid or high latitudes only have impact the hemisphere they are within. (Toprak YILDIRIM,TURKEY)
Climate change refers to significant, long-term changes in the global climate.The global climate is the connected system of sun, earth and oceans, wind, rain and snow, forests, deserts and savannas, and everything people do, too.
The climate of a place, say New York, can be described as its rainfall, changing temperatures during the year and so on. But the global climate is more than the “average” of the climates of specific places.
A description of the global climate includes how, for example, the rising temperature of the Pacific feeds typhoons which blow harder, drop more rain and cause more damage, but also shifts global ocean currents that melt Antarctica ice which slowly makes sea level rise until New York will be under water.
It is this systemic connectedness that makes global climate change so important and so complicated.
Global warming is the slow increase in the average temperature of the earth’s atmosphere because an increased amount of the energy (heat) striking the earth from the sun is being trapped in the atmosphere and not radiated out into space.
The earth’s atmosphere has always acted like a greenhouse to capture the sun’s heat, ensuring that the earth has enjoyed temperatures that permitted the emergence of life forms as we know them, including humans.
Without our atmospheric greenhouse the earth would be very cold. Global warming, however, is the equivalent of a greenhouse with high efficiency reflective glass installed the wrong way around.
Ionically, the best evidence of this may come from a terrible cooling event that took place some 1,500 years ago. Two massive volcanic eruptions, one year after another placed so much black dust into the upper atmosphere that little sunlight could penetrate. Temperatures plummeted. Crops failed. People died of starvation and the Black Death started its march. As the dust slowly fell to earth , the sun was again able to warn the world and life returned to normal.
Today, we have the opposite problem. Today, the problem is not that too little sun warmth is reaching the earth, but that too much is being trapped in our atmosphere.
So much heat is being kept inside greenhouse earth that the temperature of the earth is going up faster than at any previous time in history. NASA provides an excellent course module on the science of global warming. Mariem Essid ( Pioneer School Menzah v Tunisia )
Climate change is defined as a long-term change in temperature and weather patterns somewhere on surface of the earth.
Climate change has led to many harmful effects on the surface of the earth,the most prominent of which are:
Agricultural activities :The use of commercial and organic fertilizers leads to the release of nitrous oxide,which is considered a strong greenhouse gas.Livestock breeding also results in the release of methane,which is produced from the digestive system of livestock raised for meat production,as well as from the decomposition of waste in landfills,and the burning of organic masses.
The melting of ice sheets in the polar regions as result of global warming,which led to an increase in sea levels,which could cause floods and destroy coastal.It leads to a sharp change in the atmosphere,such as droughts,violent storms,and heavy rains,which causes people to suffer from respiratory and skin diseases,among others.
Climate change has always happened on Earth,which is clearly seen in the geological record,it is the rapid rate and the magnitude of climate change occurring now that is of great concern worldwide.Greenhouse gases in the atmosphere absorb heat radiation.
An increase in the average air temperature in the lower layer of the Earth's surface during the past one or two centuries.When the sun's heat is trapped or retained in the Earth's atmosphere after entering it,which raiser the temperature of the earth and makes it warmer as if it were it does not contain an atmosphere that protects it from these rays.This is done by absorbing the gases of the atmosphere as carbon dio5 to the sun's energy and locking them close to the earth,which helps in raising the earth's temperature to make it suitable for life.
Major eruptions alter the Earth's radiative balance because volcanic aerosol clouds absorb terrestrial radiation, and scatter a significant amount of the incoming solar radiation, an effect known as "radiative forcing" that can last from two to three years following a volcanic eruption.The eruption caused widespread destruction and loss of human life. Gases and solids injected into the stratosphere circled the globe for three weeks.
Volcanic eruptions of this magnitude can impact global climate, reducing the amount of solar radiation reaching the Earth's surface, lowering temperatures in the troposphere, and changing atmospheric circulation patterns. / (Eya Chaouachi _Pioneer school Menzah 5; Tunisia)
