Question

Causes, affects and prevention of global warming

Answer 1

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.

Each year, scientists learn more about the consequences of global warming, and many agree that environmental, economic, and health consequences are likely to occur if current trends continue. Here’s just a smattering of what we can look forward to:

Melting glaciers, early snowmelt, and severe droughts will cause more dramatic water shortages and increase the risk of wildfires in the American West.
we need to do a lot more—together with other countries—to reduce our dependence on fossil fuels and start using clean energy instead.

In 2015, the U.S. Environmental Protection Agency pledged to reduce carbon pollution from our power plants by nearly a third by 2030, relative to 2005 levels, through its Clean Power Plan. But fast-forward to 2017, and under the Trump Administration, the EPA proposed repealing this critical tool for curbing climate change. Likewise, while under the Obama administration, the U.S. Department of Transportation proposed carbon pollution and fuel economy standards intended to cut emissions through the 2020s, under Trump administration, the DOT is working to roll back those clean vehicle safeguards that protect the climate and our health.  

Answer 2

Global warming is the rising of the Earth’s atmospheric temperature. Our Earth is enveloped with a natural warm blanket that protects us from the harsh rays of the sun and allows for the nights to be cool. This atmosphere is made of green house gases like water vapor, carbon dioxide, ozone and environmental pollution. Pollution contains harmful gases like the waste from animals and fossil fuels.

The sun’s rays penetrate the Earth’s atmosphere and the Earth reflects back heat energy. Some of this energy gets stuck in our Earth and makes the Earth warm. This is natural greenhouse effect.

Causes of Global Warming

After the Industrial Revolution, we started using more energy in devices like car engines and power plants. Where do we get this energy from? Mostly fossil fuels like coal. Carbon dioxide is produced when we burn fossil fuels. This carbon dioxide floats up and increases the greenhouse effect.

Effects of Global Warming

   Icebergs and glaciers will get heated up, causing land slides, flooding and rivers will dry up.

   Tornadoes, hurricanes, droughts and more natural calamities will occur.

   Animals will not be able to withstand the heat and will die.

   Crops will wither and die.

Prevention of Global Warming

   Reduce, reuse, and recycle

   Use energy saving lamps

   Switch off lights/electronic devices when not in use
