What causes global warming?

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. Normally, this radiation would escape into space—but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter. That's what's known as the greenhouse effect.
the burning of fossil fuels to make electricity is the largest source of heat-trapping pollution, producing about two billion tons of CO2 every year. Coal-burning power plants are by far the biggest polluters. The country’s second-largest source of carbon pollution is the transportation sector, which generates about 1.7 billion tons of CO2 emissions a year.
Reducing the amount of electricity generated from coal and gas and increasing the amount of electricity from clean, renewable energy sources like solar and wind, means less carbon pollution is emitted.
This is one of the the main ways we can address global warming.

CAUSE - CO2 AND CLIMATE CHANGE

CAUSES OF CLIMATE CHANGE CO2 AND CLIMATE CHANGE The most well-known and the most important greenhouse gas is CO2. The concentration of CO2 in the atmosphere is subject to variation even without human intervention. The carbon cycle causes an exchange of CO2 between the biosphere and the oceans on the one hand and the atmosphere on the other. Vast amounts of CO2 are also released by the burning of fossil fuels. there is incontrovertible evidence that the CO2 concentration in the air has never been so high in 8,00,000 years(probably even 60 million years) as it is now. The trend suggests that CO2 emissions will continue to rise globally, although the economic crisis did prevent a rise in 2009.  Besides CO2, methane (CH4), nitrous oxide (N2o), fluorinated gases, ozone (O3) and water vapour are important greenhouse gases. Water vapour plays a unique role as it strengthens the heat-trapping effect caused by other greenhouse gas emissions. This is beca...

Deforestation

Deforestation What is Deforestation? Deforestation is when humans remove or clear large areas of forest lands and related ecosystems for non-forest use. These clearing for farming purpose, ranching and urban use. In these cases, trees are never re-planted. It is any activity directed to forests resources, with the intention of using the trees or land created for other purposes. Trees may be cut down for logs or burned to make room for farms, construction or other economic purposes. Why do humans clear forest? High demand for wood More need for pulp and paper, wood for furniture, real estate construction fuel all mean that trees will be cut down. World population is growing and more than ever before, our needs have increased too. Animal grazing fields In many places in the world, animal farms have contributed to large areas as green space being converted to grazing fields. Classic cases can be found in Brazil. Animal rearing in the Amazon has increased remarkable o...

Deforestation increases the Earth's temperature- 1

Deforestation increases the Earth's temperature Deforestation results in an increase in CO2 and other green house gases, which increases the Earth's temperature Trees plays a vital role in the equilibrium of the ecosystem. Deforestation is a process of cutting trees to make space for industries and households of the ever increasing human population. Excessive cutting of trees for urban use and other purposes are harmful to the environmental balance. It is needless to say that deforestation has several adverse effects on the environment. One of the major disadvantage of deforestation is that it disrupts the water cycle. Trees are responsible for drawing up water from the soil and releasing moisture into the atmosphere. Deforestation causes a disturbance in the water cycle and makes the environment drier. Climate change is a severe outcome of the excessive cutting down of trees. Forests lock up atmospheric carbon during the process of photosynthesis. Trees contain a m...
