Global warming and its effects on earth

Share Tweet Global warming is the current increase in temperature of the Earth's surface both land and water as well as it's atmosphere.

Average temperatures around the world have risen by 0. This is creating the global warming we see today.

These findings are recognized by the national science academies of all the major industrialized countries. It is accelerating the melting of ice sheets, permafrost and glaciers which is causing average sea levels to rise. What causes global warming?

The cause of global warming is the increasing quantity of greenhouse gases in the our atmosphere produced by human activities, like the burning of fossil fuels or deforestation. These activities produce large amounts of greenhouse gas emissions which is causing global warming. The natural greenhouse effect exists due to the balance of the major types of greenhouse gases.

However, when abnormally high levels of these gases accumulate in the air, more heat starts getting trapped and leads to the enhancement of the greenhouse effect.

What is global warming?

Human-caused emissions have been increasing greenhouse levels which is raising worldwide temperatures and driving global warming. Unfortunately, greenhouse gases generated by human activities are being added to the atmosphere at a much faster rate than any natural process can remove them.

Global levels of greenhouse gases have increased dramatically since the dawn of the Industrial Revolution in the 1750s. The majority of man-made carbon dioxide emissions is from the burning of fossil fuels such as coal and oil so that humans can power various vehicles, machinery, keep warm and create electricity.

Other important sources come from land-use changes ex: For centuries, people have burned and cut down forests to clear land for agriculture. This has a double effect on the atmosphere both emiting carbon dioxide into the atmosphere and simultaneously reducing the number of trees that can remove carbon dioxide from the air.

When forested land is cleared, soil disturbance and increased rates of decomposition in converted soils both create carbon dioxide emissions. What are the effects of global warming? Global warming is damaging the Earth's climate as well as the physical environment.

One of the most visible effects of global warming can be seen in the Arctic as glaciers, permafrost and sea ice are melting rapidly.

Global warming is harming the environment in several ways including: Desertification Increased melting of snow and ice Sea level rise Stronger hurricanes and cyclones Desertification Increasing temperatures around the world are making arid and semi-arid areas even more dry than before. Current research is also showing that the water cycle is changing and rainfall patterns are shifting to make areas that are already dry even drier.

This is causing water shortages and an intense amount of distress to the over 2.

Increased melting of snow and ice Around the world, snow and ice is melting at a much faster pace than in the past. Perennial ice cover in the Arctic is melting at the rate of 11. Stronger hurricanes and cyclones Tropical cyclone activity has seen an obvious upswing trend since the early 1970s.
