Question

How is climate change causing global warming ? Suggest measures to minimise the influence of the global warming.

Answer 1

1. What is global warming?

Global warming refers to the increasing average global temperature since the Industrial Revolution. The average global temperature has increased by about 0.8 degrees Celsius (1.4 degrees Fahrenheit) since 1880. Global warming is an ongoing process; scientists expect the average global temperature to rise an additional 0.3 to 0.7 degrees Celsius through 2035.

2. What causes global warming?

Certain gases, such as carbon dioxide and methane, help trap the sun's heat in the atmosphere. Known as greenhouse gases, they exist naturally in the atmosphere and help keep the Earth’s surface warm enough to sustain life (without greenhouse gases, the average temperature on Earth would be a mere zero degrees Fahrenheit, instead of today's roughly 58.3 degrees Fahrenheit).

Human activities, notably the burning of fossil fuels (coal, natural gas, and oil) to power vehicles, factories, and homes, release additional carbon dioxide into the atmosphere. Other activities, such as raising livestock, increase methane levels. Higher concentrations of these greenhouse gases in the atmosphere trap more heat on Earth, causing a manmade rise in global temperatures. According to multiple reviews of the scientific literature, an overwhelming 97 percent of climate scientists agree that human activity is the main driver behind the global warming we are experiencing.

 
3. What is climate change? Is it different than global warming?

The terms climate change and global warming are often used interchangeably, but climate change refers to both the rise in global temperatures because of human activities and the many impacts this rise has on the planet—such as more intense and frequent droughts and storms, melting glaciers and ice sheets, rising sea levels, warming seas (which can cause coral reef bleaching and disrupt the marine food chain), and ocean acidification (see question 7). Climate change can also refer to natural fluctuations in the Earth’s average temperature between cold periods (ice ages) and warm periods.

The climate change we are currently experiencing is almost certainly manmade in origin (see question 2). Scientists have concluded that, over the last 50 years, the Earth’s surface should have been cooling slightly based on natural factors, like solar intensity and volcano activity; instead, the increased burning of fossil fuels has led to global warming—and at a significantly faster rate than at any time over the last 800,000 years.

People around the world are already feeling the impact of climate change on the environment. A hotter atmosphere means extreme weather is more likely and potentially more devastating: droughts, flooding, and more severe storms have all become more common. Changing weather patterns can ruin crops and cause serious water shortages. Rising sea levels are threatening low-lying islands and coastal cities. Tropical and insect-borne diseases are spreading as their hosts colonize new habitats that were previously too cold for them to survive.

Climate change represents a significant threat to the health and well-being of human societies, especially in vulnerable areas of the developing world where people are ill-equipped to deal with the side effects of a warmer climate.

Answer 2

Answer:

global warming

Explanation:

it is caused due to air pollution ,water pollution,soil pollution,and noise pollution prevention of global warming is by not using small polluting like vechiles
