It refers to the long-term temperature increase of the earth's climate system observed starting from the pre-industrial period and caused by anthropogenic activities, primarily fossil fuels, which have led to an increase in the levels of greenhouse gases trapped in the atmosphere.

The chemical compound carbon dioxide (also known by its shorthand CO2) is the primary greenhouse gas and driver of climate change. It’s an integral part of life cycles on earth, produced through animal respiration (including human respiration) and absorbed by plants to fuel their growth, to name just two ways. Human activities are drastically altering the carbon cycle in many ways. Two of the most impactful are: one, by burning fossil fuels and adding more carbon dioxide into the atmosphere; and two, by affecting the ability of natural sinks (like forests) to remove carbon dioxide from the atmosphere.

Renewable energy is energy that comes from naturally replenished resources, such as sunlight, wind, waves, and geothermal heat. By the end of 2014, renewables were estimated to make up almost 28% of the world’s power generating capacity, enough to supply almost 23% of global electricity. Because renewables don’t produce the greenhouse gases driving climate change, shifting away from fossil fuels to renewables to power our lives will put us on the path to a safe, sustainable planet for future generations.

Water's extensive capability to dissolve a variety of molecules has earned it the designation of “universal solvent,” and it is this ability that makes water such an invaluable life-sustaining force.

A glacier is a big chunk of ice that is created from falling and accumulated snow over a period of time. They get created in areas where the temperatures are exceedingly low. Due to heat changes, especially to relatively high temperatures, the Glacier melting occurs a process where the ice changes from solid to liquid or water. In the recent past, scientists have discovered an alarming rate of glacier melting. This intense melting of glaciers is producing a big ripple effect like extreme flooding and biodiversity loss, and scientists have warned that the world is losing its ice fast.

Global warming is causing global mean sea level to rise in two ways. First, glaciers and ice sheets worldwide are melting and adding water to the ocean. Second, the volume of the ocean is expanding as the water warms. A third, much smaller contributor to sea level rise is a decline in the amount of liquid water on land-aquifers, lakes and reservoirs, rivers, soil moisture. This shift of liquid water from land to ocean is largely due to groundwater pumping.

Deforestation is the cutting down of trees in a large area, or the destruction of forests by people. Deforestation is destroying large areas of tropical rain forest.
A forest in good conditions regulates the global climate, houses a great biological wealth, supplies much of the water we consume and is home to millions of living beings that depend directly on them for their subsistence.
High and growing demands for wood products for construction, papermaking and furniture are part of these causes. As well as obtaining land for agriculture, livestock or for mining purposes, deforestation problems have also been impacted by the fact that the increase in urban areas, commercial or industrial construction are supported by the felling of forest areas.

Due to, the greenhouse effect is perforating and provoking the entry of ultraviolet radiation, causing negative radiative forcing, melanomas, cataracts and affecting vegetation.

Fossil fuels are a source of energy that comes from the decomposition of organic matter from animals, plants and micro-organisms, the transformation process of which takes millions of years.
The combustion of these fuels generates emissions of gases such as carbon dioxide, carbon monoxide and other gases that have contributed and still contribute to the greenhouse effect, acid rain, air, soil and water pollution.

Volcanism is a phenomenon of molten rock (magma) erupting from the Earth's surface. This causes a great deal of pollution, as it releases enormous amounts of CO2, which increases the greenhouse effect enormously. This makes the situation much worse and makes our atmosphere more vulnerable.

Ecology is the science of ecosystem studies. Ecological balance is scientifically defined as follows:Ecological balance is scientifically defined as: a state of dynamic equilibrium within a community of organisms in which genetic, species and ecosystem diversity remains relatively constant, subject to gradual changes. The most important point in an ecosystem is the preservation of the natural balance.

Greenhouse gas emissions from human activities strengthen the greenhouse effect and cause climate change. Most is carbon dioxide from the burning of fossil fuels: coal, oil and natural gas.Car exhaust,burps, and radio broadcasts are all examples of emissions. Technically, an emission is anything that's been released out into the open. But more often it refers to gases being released into the air, like greenhouse gasses or emissions from power plants and factories.Emissions of greenhouse gases from combustion of fossil fuels are associated with the global warming of Earth's climate. Certain air pollutants, including black carbon, not only contribute to global warming, but are also suspected of having immediate effect on regional climates.

An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, thus benefiting from the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction, or the need for slip rings or yaw mechanism. An electrical generator may be on the ground or airborne. Challenges include safely suspending and maintaining turbines hundreds of meters off the ground in high winds and storms, transferring the harvested and/or generated power back to earth, and interference with aviation.

Deforestation is the result of cutting down large sums of trees in a specific area. In order to make space for buildings or to collect  wood, people will cut trees down in enormous amounts. An example of how big that amount is, is that in the course of a year, areas of trees the size of Bangledash, which is a fairly big country, are being cut down.
