Important
Vocabulary

Greenhouse gas
A gas that contributes to the greenhouse effect by absorbing infrared radiation, such as carbon dioxide and methane.

Greenhouse effect
The process by which certain gases in the Earth's atmosphere trap heat, preventing it from escaping into space and thus warming the planet.

Global warming
The long-term increase in Earth's average surface temperature due to human activities, particularly the emission of greenhouse gases.

Infrared rays
A type of electromagnetic radiation with wavelengths longer than visible light, which can be felt as heat and is absorbed by greenhouse gases.

Ultraviolet rays
A type of electromagnetic radiation with wavelengths shorter than visible light, which can cause skin damage and play a role in the greenhouse effect.

Important
Vocabulary

Fossil Fuels: Natural substances formed from the remains of ancient plants and animals, used as a primary source of energy, including coal, oil, and natural gas.

Power Plants: Facilities that generate electricity by converting various forms of energy (such as fossil fuels, nuclear, or renewable sources) into electrical power.

Combustion: A chemical process in which a substance (usually a fossil fuel) reacts with oxygen to produce heat and light, often resulting in carbon dioxide and water as byproducts.

Carbon Footprint: The total amount of greenhouse gases, particularly carbon dioxide, emitted directly or indirectly by an individual, organization, event, or product, typically measured in units of carbon dioxide equivalents.

Natural Gas: A fossil fuel consisting primarily of methane, used for heating, cooking, and electricity generation, often considered a cleaner alternative to coal and oil.

Coal: A solid fossil fuel formed from the remains of ancient plants, primarily used for electricity generation and in industrial processes, but associated with high carbon emissions.

Crude Oil: A liquid fossil fuel extracted from the ground, consisting of a mixture of hydrocarbons, used to produce gasoline, diesel, and other petroleum products.

Nature vs Human change(impact)

Introduction to the Greenhouse Effect

●Definition: The greenhouse effect is a natural process that warms Earth's
surface

●Key greenhouse gases: Carbon dioxide (CO₂) and methane (CH₄)

●Importance: Maintains Earth's temperature for life to thrive

●Human activities have intensified this effect, leading to global warming

Where do anthropenic greenhouse gases come from?

Up until about 150 years ago, human activity did
not produce many greenhouse gases. That
changed as forests were cleared to make way for
cities and farms, and as important inventions and
industrial innovations, like the widespread use of
electricity and cars, transformed the way we live.

These inventions and innovations demand
energy. Burning fossil fuels — coal, oil, and
natural gas — has become an important source
of that energy. Burning fossil fuels releases
carbon dioxide and other greenhouse gases into
the atmosphere.

Carbon Dioxide (CO₂) and Its Impact

●Primary source: Burning fossil fuels (coal, oil, natural gas)

●Natural sources: Volcanic eruptions, respiration

●How it affects the greenhouse effect:

●Absorbs and re-emits infrared radiation

●Increased CO₂ levels trap more heat in the atmosphere

●Current atmospheric CO₂ levels: \(~410\) parts per million (ppm)

●Pre-industrial levels: \(~280\) ppm

Methane (CH₄) and Its Influence

●Sources: Agriculture, landfills, natural gas production

●Potency: \(~25\) times more effective at trapping heat than CO₂

●Shorter atmospheric lifetime: \(~12\) years (compared to CO₂'s \(~100\)
years)

●Recent trends: Rapid increase in atmospheric methane levels

●Impact on greenhouse effect:

●Absorbs more infrared radiation per molecule than CO₂

●Contributes significantly to short-term warming

Analyzing and Interpreting Data

●Tools for measuring atmospheric gases:

●Satellite observations

●Ground-based monitoring stations

●Key data trends:

●Rising CO₂ and CH₄ concentrations over time

●Correlation with global temperature increase

●Interpreting the data:

●Identifying human vs. natural sources

●Projecting future climate scenarios based on current trends

●Additionally, there are other
greenhouse gases which are
considered synthetic because they
are a byproduct of human
activity. Carbon dioxide is both
naturally occurring and the leading
factor in human-caused global
warming, as it is a byproduct of
many industries and types of
transportation. However, there are
also fluorinated gases like CFCs,
HCFCs, PFCs, HFCs,
and SF6SF6 and NF3NF3, which are
all considered synthetic greenhouse
gases.

Conclusion: Implications and Actions

●Summary: Changes in CO₂ and CH₂ levels significantly impact the
greenhouse effect

●Consequences: Global warming, climate change, extreme weather events

●Actions to mitigate:

●Reducing fossil fuel use

●Improving agricultural practices

●Investing in renewable energy sources

●Importance of continued data analysis and interpretation for informed
decision-making

15 Sources of Greenhouse Gases

Where do you think
anthropogenic
greenhouse gases
come from?

15 Sources Of Greenhouse Gases

#Greenhouse

Human industrial revolution has brought other problems too

●
Over time, a number of institutions have
taken measures to counter the greenhouse
effect derived from harmful gas emissions:
before the Kyoto protocol we had
the Montreal Protocol (1987), which
established the terms within which the
signatories had to contain the production
and consumption of substances that are
harmful for stratospheric ozone. These
include halon, carbon tetrachloride,
chlorofluorocarbons,
hydrochlorofluorocarbons, trichloroethane,
methyl chloroform, methyl bromide, and
bromochloromethane.

All of this adds to

Deforestation

Forests store large amounts of carbon. Trees and
other plants absorb carbon dioxide from the
atmosphere as they grow. This is converted into
carbon and stored in the plant’s branches,
leaves, trunks, roots and in the soil.

When forests are cleared or burned, stored
carbon is released into the atmosphere, mainly
as carbon dioxide. carbon stored in these sinks is
part of an active, relatively quick carbon cycle. As
living things (including trees) die and decay, the
carbon that they once stored is released back
into the atmosphere.

Fossil Fuels

Carbon stored underground in the form of fossil
fuels such as coal, oil and gas, is much more
stable, and is part of a much slower carbon
cycle. Without the influence of humans burning
these fossil fuels for energy, this carbon would
be unlikely to reach the atmosphere. When fossil
fuels are burned, carbon from dead and decayed
plants, animals and phytoplankton that lived
hundreds of millions of years ago (before
dinosaurs existed), is released into the
atmosphere in the form of carbon dioxide.

Today in the United States, electricity and transportation (cars, trucks and
planes) are responsible for almost 60 percent of carbon dioxide emissions.
The rest comes from agriculture, industry – such as factories that make
products we use – and from energy we use in our homes and businesses.

Rising Temperature

As global carbon emissions have increased, so have global temperatures. The
following charts show how both emissions and temperatures have gone up
since 1900, and the projections for how they could continue to change in the
future. If we continue on our current path, and emit more and more
greenhouse gases, the temperature of the Earth will rise a lot – maybe as
much as 5 degrees Celsius (9 degrees Fahrenheit) by 2100. However, if we
reduce our emissions, the temperature of the Earth will still rise but we might
be able to keep the rise below 2 degrees Celsius (or about 4.8 degrees
Fahrenheit).

Human Impact

The Impact of Global Warming

Global warming is a serious environmental
issue that occurs when certain gases,
known as greenhouse gases, accumulate in the Earth’s
atmosphere. These gases, such as carbon dioxide
and methane, trap heat from the sun, preventing
it from escaping back into space. As a result,
the average temperature of the planet increases,
leading to various consequences like rising
sea levels and more extreme weather patterns.
This trapping of heat is a major factor in
climate change, affecting ecosystems
and human communities around the world.
It is crucial for us to understand and address
the sources of greenhouse gases to mitigate
the effects of global warming and protect
our planet for future generations.
