Global Warming Introduction

Global Warming is the changing of climate all across the world. Climate change is referred to the transformation of climate on a global level. There has been a transformation of climate on a global level previously but the current changes are up at a rapid pace. So this long-term alteration of temperature and change in weather patterns is becoming a concern globally. In today’s topic, we will focus on global warming, responsible factors, what are its impacts globally, and how to stop global warming.

Global Warming

What is global warming? Definition

Global warming is defined as an increase in the earth’s temperature. Because of natural causes, the earth’s climate has changed from ice ages to warmer periods for many years. Temperatures on planet Earth have risen by an unusually large amount in the last century, about 1.2 – 1.4 degrees. Scientists believe it’s due to some activities of humans that are the cause of rising temperatures. This rise in temperature globally is known as global warming.

Global Warming

According to Scientist Research

Whenever industrial countries are consuming fossil fuels, and non-renewable energy sources, the factors resulting in climate change are sure to increase. Scientists did a lot of research around the world to track climatic changes and they found below mentioned points in their research

  •  Evidence of climatic change frequencies.
  •  Evidence pertaining to climate such as serious changes in hurricanes, heatwaves, droughts, etc.

According to the calculations of Scientists, the world needs to reduce global carbon emissions by as much as 40 percent by the year 2030.

Causes of Global Warming

Human activity is directly responsible for global warming today. Many factors contribute to global warming include:

  • Starting of the Industrial Revolution led to emerging of factories, power plants, locomotives, automobiles, etc.
  • The burning of non-renewable sources such as fossil fuels for energy needs constantly releases greenhouse gases into the air which trap heat near the earth’s surface by a phenomenon called the greenhouse effect.
  •  Now scientists are at the conclusion that the greenhouse effect is being intensified by the extra greenhouse gases that humans have released. Especially the burning of fossil fuels such as coal, oil, gasoline, and natural gas, which results in the greenhouse effect.
  • Extensive use of electronic products like Air Conditioners, Refrigerators, is also increasing level of global warming. The CFCs used in Air Conditioners, and refrigerators are very dangerous to our environment.

Effects of Global Warming on Earth

Global warming is a global concern hence its impacts are attributed globally such as:

  • We had 10 warm years since 1880 among which 9 out of 10 have occurred since 2005. Basically, global warming is a pathway to extreme weather conditions. While 2016 is recorded as the warmest year since 1880.
  • Arctic sea ice loss is one of the most dramatic effects of global warming. Both the fall and winter of 2015 and 2016 saw record-low sea ice extents, meaning that at the time when the ice should have been at its peak, it was not. Due to the melt, there is less thick sea ice that persists for several years.
Arctic Ocean
  •  Arctic ice has declined 10% in the last 30 years.
  • When the ice melts, the sea level automatically rises. The rate of sea level rise doubled from 0.08 inches (2.1 millimetres) per year between 1993 and 2002 to 0.17 inches (4.4 millimetres) per year between 2013 and 2021.
  • As ocean levels rise, coastal areas, where roughly half of the Earth’s human population lives, will be flooded.
  • 2015 was recorded a lengthy drought in California for 1200 years which means it’s a 20% change in global warming.
  • The National Academy of Sciences reported that many species of plants and animals are already moving northward or to higher altitudes because of warming temperatures. Species unable to adapt to the changing conditions would face extinction.
  • There is a category of storms starting from 1 to 5 and scientists believe global warming has the ability to turn category 3 to category 4 storms.
  • In the year 2020, the Atlantic hurricane season included a record-breaking 30 tropical storms, 6 major hurricanes, and 13 hurricanes altogether.
  • Other impacts on seas such as rising sea levels, and disappearing glaciers. Disturbances in aquatic life.
  • Additionally, impacts will eventually increase in disturbances in aquatic life, frequent floods, infectious diseases, and disruption of habitats.

How to Stop Global Warming

Global warming is mainly caused by developing countries, so it is their responsibility to contribute to activities that will lower the temperature of our mother earth and prevent upcoming destruction.

  • All countries should stand up and work with each other.
  • Switch to renewable sources and go solar for lighting and heating purposes in homes.
  • Government should make plans and schemes that will help people to switch to electric automobiles or hybrid cars.

Global Warming
  • Over the past decades, there has been a growing demand for building houses from wood, resulting in the cutting down of more and more trees. We need to plant trees instead of cutting them.
  • Support Local utility markets or businesses that promote& support climate-smart practices.
  • Local-level like in homes consumers can switch to fluorescent light bulbs, turn off electronics that are not in use,
  • We should lower our reliance on fossil fuels and non-renewable energy sources for our energy needs
  • We need to follow the mantra of Reduce, Reuse, and Recycle.

 By making these simple changes, we may be able to keep the earth’s temperature cooler in the future.


 The numerous impacts of global warming have led us to conclude that it is a serious challenge for our society. Global warming is not only a threat to humans and future generations but also to animals and the sea. As individuals, we must do what we can for the planet, even change our lifestyle and adapt accordingly, in addition to relying on government policies. Once we realize and work on possible solutions, we can mitigate climate-changing factors altogether
