Climate Change vs Global Warming

NASA: Climate Change

When any change lasting for an extended period of time happens it refers to significant climate change. An ongoing rise in global average temperature approximating Earth's surface refers to global warming.

If you hear global warming, most of the time climate change will follow. People believe they go hand in hand, but they’re in fact two different events. 

             Throughout the years our climate has changed. Studies show that the Earth’s climate is undergoing change faster than ever. These long-lasting effects can be caused by natural forces of man-made issues.

Warmer conditions might lead to more evaporation and precipitation. Other places might become wetter and others drier. 

Loss of sea level, harsher heat waves, and accelerated sea level rise are examples of climate change. Many believe that global temperatures will continue to rise for years to come.

Climate change is very likely to affect farming. It can change food availability, affect food quality and make it more complicated to access food.

Any change to food transportation may have crucial impacts on food access. According to www.Epa.gov, “food transportation system in the United States frequently moves large volume of grain by water”. 

The lack of food storage can cause crisis and concerns. Less access to food can increase food prices. 

 

How are we responsible?

Humans release greenhouse gases that keeps heat in the Earth’s atmosphere. We are constantly burning fossil fuels such as planes, factories, trucks, cars and even power plants then releasing carbon dioxide,methane, water vapor, and more. Not all greenhouse gases are bad. If there wasn't any natural greenhouse gases, the earth would be freezing.

 

Global Warming

Global warming occurs when carbon dioxide and other air pollutants and greenhouse gases collect in the atmosphere. (There is more carbon dioxide in the atmosphere today than at any other point in the last 800,000 years). Normally, the radiation would escape, but because of pollution, the heat is trapped. Please see diagram below

According to www.nrdc.org, “Scientists agree that the Earth's rising temperatures are fueling longer and hotter heat waves.” The Earth's ocean temperatures are getting warmer. If global warming took a worse turn, a category 3 storm can turn into a category 4 storm. This rate could speed up if we continue to burn fossil fuels. Allergies,asthma, and infectious diseases will become more common due to higher levels of air pollution. Global warming can be seen anywhere. Higher temperatures are intensifying numerous disasters, including rising sea levels,tsunamis,volcanic activity,brought fires,floods and more.

According to a report by the Government Accountability Office, “Climate change and global warming has cost the U.S more than $350 billion over the past decade.

 

Why humans are to blame for Global Warming?

Since the 1700s, humans have been releasing large amounts of greenhouse gases from burning more fossil fuels to run our everyday life. We have also increased the amount of carbon dioxide. There can be no doubt that global warming and climate change are similar, but despite their similarities, they are both affecting our planet.
