What is Global Warming?

Global warming occurs when Earth’s atmosphere warms due to increased levels of greenhouse gases in the air. Greenhouse gases trap heat within our planet by absorbing infrared radiation emitted by its surface. This causes temperatures to rise at a rate faster than would otherwise be expected without these additional emissions. The most important greenhouse gas is carbon dioxide which makes up about half of all human-made emissions.

Other significant contributors include methane, nitrous oxide, and ozone. The average surface air temperatures around the world have increased by 1 degree Fahrenheit since 1880. This has led to melting ice caps, rising sea levels, more frequent heatwaves, droughts, floods, wildfires, and other effects that are already being felt worldwide.

What causes global warming?

Greenhouse gases like carbon dioxide, methane, nitrous oxide, and ozone trap heat from the sun inside our atmosphere. When these greenhouse gases build up over time — through human activities such as burning fossil fuels, deforestation, landfills, agriculture, and waste management — they contribute to an overall buildup of atmospheric heat. This excess heat then warms Earth’s surface, oceans, and
lower levels of the atmosphere.

Effects of Global Warming Are as Follows :

1. More Immortality rate.

2. Air Pollution Increases.

3. Greater danger of Extinction of Animals.

4. Higher sea Levels.

5. Water Turning More Acidic.

6. Threat to crops.

Where does the United States stand in terms of global-warming contributors?

The United States is still number one, by far, in cumulative emissions over the past 150 years. It is second in emissions after China. As a top contributor to global warming, the United States must help propel the world to a cleaner, safer, and more equitable future. Our responsibility matters to other countries, and it should matter to us, too.

Is the United States doing anything to prevent global warming?

Industry and business leaders have been working with the public sector to create and adopt new clean-energy technologies and increase energy efficiency in buildings, appliances, and industrial processes.

Today the American automotive industry is finding new ways to produce cars and trucks that are more fuel-efficient and is committing itself to put more and more zero-emission electric vehicles on the road. Developers, cities, and community advocates are coming together to ensure that new affordable housing is built with efficiency in mind, reducing energy consumption and lowering electric and heating
bills for residents. And renewable energy continues to surge as the costs associated with its production and distribution keep falling. In 2020 renewable energy sources such as wind and solar provided more electricity than coal for the first time in U.S. history.

How do I know whether my actions will make any difference?

If you want to help stop global warming, your first step should understand how your personal choices affect the environment. You may think that buying an electric car won’t matter because they only account for less than 3 percent of U.S. vehicle sales. But consider what happens after you drive home with your new Tesla Model S.
