Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner.
Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves
There are many causes of Climate Change the most important of them Earth's temperature is a balancing act .The greenhouse effect causes the atmosphere to retain heat .Changes in the sun's energy affect how much energy reaches Earth's system .Changes in reflectivity affect how much energy enters Earth's system.
Human activities, such as burning fossil fuels(coal, oil and natural gas) to make electricity and power vehicles, clearing forests for farms and cities, and cultivating livestock, release “greenhouse gases” into the atmosphere.
There are many tools about every habitat on the planet. Approaches include permaculture, holistic planned grazing, wetland restoration, reintroduction of native keystone species (e.g., otters, kelp, prairie dogs, mangrove forests, beaver), innovative water cycle management, reforestation, biochar, rock powders, coastline and fisheries restoration, regenerative agriculture – the list of promising options continues to grow. And we know how to put these into practice – nowز

Climate change in the world can be caused by 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.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. Global warming is due to the enhancing greenhouse gases emission and build-up in the Earth’s environment. The gases that have an influence on the atmosphere are water vapor, carbon dioxide, dinitrogen-oxide, and methane.atmosphere. Cars and trucks can effect climate by releasing carbon dioxide when fossil fuels are burned to power them.In conclusion, we need to take part and try to stop global warming and other effects on climate change. If the earth’s temperatures continue to rise in the future, living things on earth would become extinct due to the high temperatures. If humans contribute to control global warming, this world would be cooler and the high temperatures we currently have would decrease. If everybody as one take stand and try to end most of the climate changes that are occurring, this world would be a safer place to live on.

Today one of the hottest topics around the globe is “Climate Change” which is threatening our life on Earth. Climate change refers to the adverse change in the environment and its impacts on the living organisms on Earth. The climate of Earth has become warmer over the last two million years for which, climate change and global warming is responsible. The absurd increase in the atmospheric temperature leads to various drastic changes in the Earth, for example, season shift. Deforestation, the burning of fossil fuels, and other human activities are the most important reasons for global warming, which causes a variation in the climate.

Forest fire, intense rainfall, melting of the glaciers are so the horrific climate changes brought around by global warming. We need to prevent global warming to live a peaceful and happy life. Afforestation should be practiced, and the exploitation of the existing natural resources must be immediately cut down. Climate change and global warming are some severe issues that demand attention so that Earth can heal.
These changes that we have caused to the ecosystem are not reversible. The only thing we can do is try to make the biosphere a better place to live in. Because in the upcoming days it is predicted that the Earth’s temperature will rise day by day leading to the extinction of life and this is because of the increasing amount of greenhouse gases being released in the atmosphere. The greenhouse gases trap in the heat which is supposed to be emitted.

The phenomena of the increase of toxic gases in the atmosphere surrounding the Earth since the beginning of the industrial revolution; man’s evolution was at the expense of the threat of the planet One of the phenomena that accompanied the increase of toxic gases is what is known as global warming. Global warming is the gradual rise in the temperature of the first layer of the atmosphere around the globe than the limit due to the increase of toxic gases.
The modern science has been unable to give a clear reason for it, but scientists have agreed on several reasons that may be behind this phenomenon, including:

Oil refining and petrochemical processing.

Factory waste from fumes and toxic gases emitted into the atmosphere.

Vehicle exhausts from cars, trains and others.

Environmental pollution caused by frequent industrialization, fires, volcanic eruptions, and the emission of gases without treatment to reduce their damage to the atmosphere.

The disappearance of green areas, logging and forests that functioned as a purification machine for the atmosphere of greenhouse gases and toxic.

The solar wind coming from the sun and increases the temperature of the sun which has greatly affected the warming of our planet.

Climate change refers to the change in the environmental conditions of the earth. This happens due to many internal and external factors. The climatic change has become a global concern over the last few decades. Besides, these climatic changes affect life on the earth in various ways. These climatic changes are having various impacts on the ecosystem and ecology. Due to these changes, a number of species of plants and animals have gone extinct.Man due to his need and greed has done many activities that not only harm the environment but himself too. Many plant and animal species go extinct due to human activity. Human activities that harm the climate include deforestation, using fossil fuel, industrial waste, a different type of pollution and many more. All these things damage the climate and ecosystem very badly. And many species of animals and birds got extinct or on a verge of extinction due to hunting.If we do not do anything and things continue to go on like right now then a day in future will come when humans will become extinct from the surface of the earth. But instead of neglecting these problems we start acting on then we can save the earth and our future.Although humans mistake has caused great damage to the climate and ecosystem. But, it is not late to start again and try to undo what we have done until now to damage the environment. And if every human start contributing to the environment then we can be sure of our existence in the future.

The climate started changing a long time ago due to human activities but we came to know about it in the last century.
During the last century, we started noticing the climatic change and its effect on human life. We started researching on climate change and came to know that the earth temperature is rising due to a phenomenon called the greenhouse effect.
The warming up of earth surface causes many ozone depletion, affect our agriculture, water supply, transportation, and several other problems.
These climatic changes have a negative impact on the environment. The ocean level is rising, glaciers are melting, CO2 in the air is increasing, forest and wildlife are declining, and water life is also getting disturbed due to climatic changes. Apart from that, it is calculated that if this change keeps on going then many species of plants and animals will get extinct. And there will be a heavy loss to the environment.
