Global warming is the phenomenon of gradual increase in the average temperature of earth . It is caused by the release of greenhouse gases like carbon dioxide, methane, CFCs etc. into the atmosphere. https://healthhouseeveryone.blogspot.com/2023/04/what-is-global-warming.html

1. What Is Global Warming?
Global warming is the phenomenon of a gradual increase in the
temperature near the earth’s surface. This phenomenon has been
observed over the past one or two centuries. This change has disturbed
the climatic pattern of the earth. However, the concept of global warming
is quite controversial but the scientists have provided relevant data in
support of the fact that the temperature of the earth is rising constantly.
There are several causes of global warming, which have a negative effect
on humans, plants and animals. These causes may be natural or might be
the outcome of human activities. In order to curb the issues, it is very
important to understand the negative impacts of global warming.

2. Within the earth's atmosphere, accumulating greenhouse gases like water
vapor, carbon dioxide, methane, nitrous oxide, and ozone are the gases
within the atmosphere that absorb and emit heat radiation. Increasing or
decreasing amounts of greenhouse gases within the atmosphere act to
either hold in or release more of the heat from the sun.
Our atmosphere is getting hotter, more turbulent, and more
unpredictable because of the “boiling and churning” effect caused by the
heat-trapping greenhouse gases within the upper layers of our
atmosphere. With each increase of carbon, methane, or other
greenhouse gas levels in the atmosphere, our local weather and global
climate is further agitated, heated, and “boiled.”
Global warming is gauged by the increase in the average global
temperature of the Earth. Along with our currently increasing average
global temperature, some parts of the Earth may actually get colder while
other parts get warmer—hence the idea of average global temperature.
Greenhouse gas-caused atmospheric heating and agitation also increase
the unpredictability of the weather and climate, and dramatically increase
the severity, scale, and frequency of storms, droughts, wildfires, and
extreme temperatures.
Global warming can reach levels of irreversibility, and increasing levels of
global warming can eventually reach an extinction level where humanity
and all life on earth will end. In this book, irreversible global warming is
defined as a continuum of increasing temperature that causes the global
climate to rapidly change until those higher temperatures becomes
irreversible on practical human time scales. The eventual temperature
range associated with triggering and marking the beginning of the
irreversible global warming processes is an increase in average global
temperature of 2.2°-4° Celsius (4°-7.2° Fahrenheit) above preindustrial
levels.
Extinction level global warming is defined in this book as temperatures
exceeding preindustrial levels by 5-6° Celsius (9-10.8° Fahrenheit) or the
extinction of all planetary life, or the eventual loss of our atmosphere. If

3. our atmosphere is also lost, this is referred to as runaway global warming.
The result would be similar to what is thought to have happened to Venus
4 billion years ago, resulting in a carbon-rich atmosphere and minimum
surface temperatures of 462 °C.
How long carbon dioxide remains in our
atmosphere
Carbon dioxide is currently the most important greenhouse gas related to
global warming. For the longest time, our scientists believed that once in
the atmosphere, carbon dioxide remains there for about 100 years. New
research shows that is not true. 75% of that carbon will not disappear for
thousands of years. The other 25% stays forever. We are creating a serious
global warming crisis that will last far longer than we ever thought
possible.
"The lifetime of fossil fuel CO2 in the atmosphere is a few centuries, plus
25 percent that lasts essentially forever. The next time you fill your tank,
reflect upon this...[the climatic impacts of releasing fossil fuel CO2 to the
atmosphere will last longer than Stonehenge… Longer than time
capsules, longer than nuclear waste, far longer than the age of human
civilization so far."
Overfishing
The globe currently heavily depends on the fish business because fish is
one of the primary sources of protein for humans. There is currently less
marine life since fewer people are buying and eating fish. Overfishing has
also caused a lack of diversity within the water.

4. Marine ecosystems are facing a huge problem: overfishing. This happens
when too many fish are taken from the ocean, more than can be replaced
naturally.

5. How carbon dioxide in our atmosphere is
tracked
Atmospheric carbon from fossil fuel burning is the main human-caused
factor in the escalating global warming we are experiencing now. The
current level of carbon in our atmosphere is tracked using what is called
the Keeling curve. The Keeling curve measures atmospheric carbon in
parts per million (ppm).
Each year, many measurements are taken at Mauna Loa, Hawaii to
determine the parts per million (ppm) of carbon in the atmosphere at
that time. At the beginning of the Industrial Revolution around 1880,
before we began fossil fuel burning, our atmospheric carbon ppm level
was at about 270. Here is the current Keeling curve graph for where we
are today:
As you can see, we are not doing very well. In later chapters, you will
learn what this exponentially rising carbon means to your future. You also
will see other graphs that will show you how today’s atmospheric carbon
levels compare to those of our near and far distant past (hundreds,
thousands, hundreds of thousands, and millions of years ago).
No matter what you hear in the media, if the total carbon ppm level is not
going down or carbon’s average ppm level per year is not falling or at least
slowing its steep increase, we are not making any significant progress on
resolving the escalating global warming emergency. Total atmospheric
carbon and carbon’s average ppm level per year are the mostdependable
measurements of our progress and a predictor of what will be happening
with global warming and its many consequences.
Industrialization
The pollution brought on by industry is referred to as industrial pollution.
The industrial revolution brought about increased industrialization and

6. technological advancement. This, however, caused significant pollution of
our planet's air, land, and water.
Pollution from industry is one of the worst types. This is because the
smoke released into the air contributes to ozone depletion. It also affects
the health of animals and humans, as well as global warming.

7. Power plants
In a study published in Environmental Research Letters, 5% of the 29,000
power plants surveyed were responsible for 73% of the global electricity
generation industry’s C02 emissions. These “hyper-polluting” power
plants, as the study calls them, are found in places like East Asia, India,
and Europe. Inefficiency is a big reason. Coal plants in particular are a
problem. There are around 8,500 coal power plants in operation globally,
but they produce ⅕ of total greenhouse gases. This makes them the
largest single source. Smithsonian Magazine names a 27-year-old power
plant in Poland, which produces 20% of Poland’s electricity using brown
coal, an especially “dirty” form of coal. Globally, coal plants generate over
⅓ of all electricity, so we need to turn to other sources quickly.

8. Agriculture
According to The World Bank, agriculture is a big driver of climate change.
It produces between 19-29% of total greenhouse gas emissions. Emissions
are likely to rise due to the demand for more food production to feed the
world’s growing population. Where are the problems originating from?
Methane is a big concern since it is 26 times stronger than carbon dioxide.
Methane is released from livestock and rice production. About ⅓ of
agriculture’s global methane emissions come from livestock. Rice grown
in rice paddies also produces a lot – about 11% of agriculture’s emissions.
Nitrous oxide – which is 300 times stronger than CO2 – is also a problem!
60% of human-caused N2O emissions come from agriculture. It’s
produced after croplands are fertilized and after crop residues get burned.
Vehicles and transport
According to the Center for Biological Diversity, transportation is
responsible for around ⅓ of the United States’ greenhouse gas emissions.

9. Transport includes more than cars. At 9%, airplanes make up the
third-largest source of emissions in the United States. Globally, the
aviation industry will likely produce around 43 metric gigatons of CO2
through 2050. Globally, ships release almost 3% of the world’s carbon
dioxide emissions. With expanding international trade, it’s expected that
ship and boat emissions could increase 250% by 2050. To reduce
emissions from vehicles and other transport, the world needs solutions
like increased technology efficiency, changes in how people travel and
move goods, and lower-carbon fuel sources.
Waste
Humans are creating more waste than ever before. This is due to the
extensive use of packaging and the short life cycle of products.
The majority of items, waste and packaging aren't recyclable, which
means it ends up in landfills. Waste in landfills decomposes, releasing

10. harmful gases into the atmosphere. These gases contribute to global
warming.
Deforestation
Deforestation is the clearing of woodland and forest. This is often done to
extract wood or to make space for farming or ranching.
Deforestation contributes to global greenhouse gas emissions. It is
responsible for approximately 25% of them. This, combined with land use
changes and agriculture, makes it a considerable factor in climate change.
Forests and trees are essential for absorbing carbon dioxide and creating
oxygen. When they are destroyed, the stored carbon is released into the
atmosphere.

11. Natural deforestation happens often. It is usually caused by wildfires.
These fires can have a bigger effect on the environment because of the
fumes they release.
Landfills
Landfills present serious risks to the environment and human health. Our
old friend methane is a big reason why. As organic waste (like food waste)
sits in landfills, the decomposition process releases methane gas. Since
2016, NASA’s Jet Propulsion Laboratory and Scientific Aviation, a
leak-detection firm, have performed flyovers over landfills in California.
Commissioned by air-quality regulators, the years-long survey revealed
that “super-emitters” landfills were responsible for 43% of measured
methane emissions. This puts landfills above fossil-fuel and agricultural
sectors in the state. Results also showed that the ten biggest culprits were
averaging 2.27% over the federal estimates of methane emission. This is
just one example of the impact landfills have on global warming.
Considering how many landfills there are in the world, they deserve more
attention.
Offshore drilling
Offshore drilling is the extraction of petroleum in rock formations beneath
the seabed. Companies drill wellbores. Measuring the impact of offshore
drilling is extremely important because of how many offshore platforms
there are. For a while, offshore drilling was considered efficient with
limited methane leakage. However, a study by scientists from Princeton
University found that extracting oil and natural gas in the North Sea
released a lot more methane than previously estimated. The survey found
that on average, methane leakage during normal operations was more
than double the reported emissions. Offshore drilling also threatens
ocean health and human health with spills and pollution. Burning the

12. fuels extracted through offshore drilling increases greenhouse gas
emissions, as well.
Producing Food
Producing food causes emissions of carbon dioxide, methane, and other
greenhouse gases in various ways.

15. Many factors affect the environmental impact of the food we buy and eat.
As mentioned above these include the farming methods, where food is
grown, the use of pesticides and fertilizers, and what is fed to our
livestock.
All this makes food production a major contributor to climate change. And
greenhouse gas emissions also come from packaging and distributing
food.
