What is Global Warming?

Global warming, just as the name suggests, is the increase of the Earth’s average surface temperature and its oceans, and this happens due to greenhouse gases released as people burn fossil fuels.

These greenhouse gases, such as carbon dioxide and methane, absorb heat that would otherwise bounce off the Earth’s surface. Global warming has emerged as one of the most significant environmental issues in the last two decades.

“The global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years. Temperatures are certain to go up further.”


It seems that the temperature is rising at a rate faster than ever before. Human activities like the burning of fossil fuels, deforestation, industrialization, and increase in pollution are considered as few of the factors responsible for the rise in global warming.

This term, which was first used in the year 1975 in a science article written by a geochemist Wallace Broecker of Columbia University’s Lamont-Doherty Geological Observatory, has sparked many speculations and discussions ever since.

Now, as we stand in the middle of the 21st century, there is one question that we definitely have to ask ourselves. Have we really taken global warming seriously enough? Are we doing our bit to save our planet from the brink of overheating?

HowStuffWorks defines global warming as,

Global warming is a significant increase in the Earth’s climatic temperature over a relatively short period of time as a result of the activities of humans. In specific terms, an increase of 1 or more degrees Celsius in a period of one hundred to two hundred years would be considered global warming. Over the course of a single century, an increase of even 0.4 degrees Celsius would be significant.

More from global warming:

War contributes greatly to global warming, which shouldn’t surprise us. All those bombs going off, all those rockets, all those planes and helicopters. All that fuel of various kinds being used. It pollutes the air and water of this very fragile and interconnected planet.

Below are 40 Surprising Facts About Global Warming

Enough of everything we’ve said so far. Let’s now dive deep into our today’s nitty gritty and see what global warming truths are:

Fact 1: Global warming is the result of an increase in the earth’s average surface temperature due to greenhouse gases like carbon dioxide and methane. These gases are required for the presence of human life on Earth. However, global warming is happening due to the over-emittance of these gases.

Fact 2: Emissions like carbon dioxide, nitrous oxide, and other greenhouse gases will remain in the atmosphere for many years, making it impossible to eliminate global warming for several decades.

Fact 3: According to the IPCC 2007 report, sea levels will rise by 7-23 inches by the end of this century due to global warming.

Fact 4: Since 1880, the average temperature has risen by 1.4-Fahrenheit degrees. It may look like a slight difference, but it’s a huge one on a global scale.

Global Warming Happening

Fact 5: The last two decades of the 20th century have been the hottest in the past 400 years, according to climate studies.

Fact 6: The Arctic is one of the worst places to be affected by global warming.

Fact 7: According to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004, the average temperature in Alaska, Western Canada, and Russia has risen at twice the global average.

Fact 8: The Arctic ice is melting rapidly. By 2040, the region is expected to have a completely ice-free summer or even earlier.

Fact 9: The Montana Glacier National Park has only 25 glaciers instead of 150 that were there in the year 1910. That’s 125 glaciers that have melted in just over a century.

Fact 10: Due to global warming and pollution, coral reefs are suffering the worst bleaching, with the highest dying record since 1980.

Fact 11: Global warming that is causing extreme weather changes has shown its implications in the way of forest fires, heatwaves, and severe tropical storms throughout the world.

Fact 12: There has been a tremendous increase in water vapor, carbon dioxide, methane, nitrous oxide, and other greenhouse gases due to polluting substances emitted as a result of industrialization, pollution, and deforestation.

Fact 13: Humans are emitting more carbon dioxide into the atmosphere faster than the absorbing rates of plants and the oceans.

Fact 14: Sea levels have risen about 7 inches in the last 100 years, which is more than the previous 2000 years combined. The rising sea levels due to global warming could threaten the lives of people living in the coastal areas.

Fact 15: Around 100 million people live at 3 feet of sea level, and many cities of the world are located near such vulnerable coastal areas.

Fact 16: The melting of glaciers will cause sea levels to rise and water shortages in areas that depend on natural sources of water on the other.

Fact 17: More than 1 million species have become extinct due to disappearing habitats, ecosystems, and acidic oceans, all caused due to global warming.

Fact 18: Global warming will completely alter the ocean’s conveyer belt, which will cause a mini ice age in Europe.


Fact 19: The trouble is only expected to grow worse. That’s because the increasing temperatures will release more greenhouse gases, unlock methane, and cause more evaporation of water.

Fact 20: 2011-2020 has been the hottest decade recorded on the earth. But this might soon be replaced by the decade we’re currently in, considering that 2023 is already the hottest year ever recorded.

Fact 21: The rate at which carbon dioxide is being dumped into the environment was 1000 tons per second until the 2011 records.

Fact 22: The carbon dioxide levels in the 20th century have been highest in 650,000 years.  Till 1950, the levels rose by 11%, and recently the levels have risen by 40%.

Fact 23: Due to the Industrial Revolution, the burning of fossil fuels like coal, oil, and gas started on a massive scale. This not only increased greenhouse gases but was also responsible for large-scale deaths due to asthma and other respiratory diseases.

Fact 24: Human activities release around 37 billion metric tons of carbon dioxide per year.

Fact 25: Since the Industrial Revolution in 1700, the level of carbon dioxide on earth has increased by 34%.

Fact 26: By the year 2100, the average temperature will rise by 5.8 degrees as a result of global warming.

Fact 27: Each year of the 21st century ranks amongst the 23 hottest years since 1880. The most recent, 2023, goes down as the hottest year ever recorded.

Fact 28: In the last 30 years, the average consumption of fossil fuel by the United States has been 80%. Fossil fuels are the most dangerous contributors to global warming.

Fact 29: Between 2000-2100, the heat-related deaths will rise by 150,000.

Fact 30: Global warming is causing colder areas of the world to become hotter, thereby becoming more vulnerable to diseases.

Fact 31: A failure in preventing global warming can cause a significant economic collapse causing 20% of global domestic output to fix.

Fact 32: Droughts, hurricanes, wildfires, extinction of endangered species, melting of polar ice caps, and storms are a few of the effects of global warming.

Fact 33: The NRDC (Natural Resources Defense Council) proposed the Clean Air Act to cut power plant emissions by 26 percent in the next 7 years.

Fact 34: The heat-trapping gases have been increasing in the atmosphere at an alarming rate. The presence of a large number of these gases has resulted in an enhanced greenhouse effect. Heatwaves caused by global warming are responsible for many heat-related illnesses and deaths.

Fact 35: Global warming can lead to massive food and water shortages and has a life-threatening impact on wildlife.

carbon dioxide emissions

Fact 36: America contributes only about 4% of the world’s population, but they are responsible for a staggering 25% of the total carbon dioxide emissions. In recent years, however, China has taken the lead by producing 28% of carbon dioxide emissions. This makes them the top contributing country.

Fact 37: Many scientists have now pointed out that global warming is the biggest latent health threat of the 21st century. It is a problem that affects us all, from the young to the old and from the rich to the poor. All this means that this would give a steep rise to the death rates across the globe.

Fact 38: A 2015 study reveals that vertebrate species are going extinct at a rate that is 114 times faster than it actually should be. The situations could become worse if the situations are not controlled at the earliest.

Fact 39: Global warming also messes with air pollution levels. With the increase in the mean temperature conditions, the ground level of ozone also rises steeply. It is this ozone that forms a significant component of the smog.

Fact 40: The costs incurred on natural disasters will keep increasing drastically if the global warming levels are not controlled at the earliest. A little survey into the facts will help us understand better. From 1980 to 2011, the average cost was $5.2 billion. Now, between the years 2011 and 2015, the average cost was $10.8 billion.

If these figures do not startle, then it will be tough to prevent the world from collapsing from global warming. Many schools, organizations, government bodies, etc., are making efforts to encourage people to take steps that would prevent them from taking any action that would lead to global warming. The most important consideration, however, is to feel for the problem and to be fully awakened to the situation.

Unless the critical issue of global warming does not hit every person on Earth, it will be very difficult to prevent the world from burning due to global warming in the near future.
