Ano ang Greenhouse Effect? | Tanaw Episode #5
Summary
TLDRThe video script discusses the greenhouse effect, a natural process where certain gases in Earth's atmosphere trap heat, keeping the planet warm. It explains how greenhouse gases like carbon dioxide and methane absorb and re-emit radiation, maintaining Earth's temperature. The script also touches on the impact of human activities, such as burning fossil fuels, which increase these gases and exacerbate global warming. It concludes by hinting at future content on how individuals can contribute to mitigating this environmental issue.

Q & A
What is the greenhouse effect?
-The greenhouse effect is a process where certain gases in the Earth's atmosphere trap radiation, preventing heat from escaping and thus warming the planet.
How does a greenhouse structure relate to the greenhouse effect?
-A greenhouse structure allows sunlight to pass through its glass or walls, trapping heat inside and creating a warm environment. This is analogous to how greenhouse gases in the Earth's atmosphere trap heat.
What are the primary greenhouse gases?
-The primary greenhouse gases include carbon dioxide, water vapor, methane, and fluorinated gases like chlorofluorocarbons.
Why are greenhouse gases important for life on Earth?
-Greenhouse gases are essential for maintaining the Earth's temperature at a level suitable for life. Without them, the average global temperature would be much colder, making life as we know it impossible.
How does the burning of fossil fuels contribute to the greenhouse effect?
-Burning fossil fuels releases carbon dioxide and other greenhouse gases into the atmosphere, which increases the concentration of these gases and enhances the greenhouse effect.
What is the 'Keeling Curve' and why is it significant?
-The Keeling Curve is a graph that shows the increase of carbon dioxide concentration in the Earth's atmosphere over time. It is significant because it visually demonstrates the impact of human activities on the environment.
How does the increase in greenhouse gases affect the environment?
-An increase in greenhouse gases leads to higher global temperatures, which can cause the extinction of flora and fauna species, as well as other environmental changes.
What are some ways to reduce the impact of greenhouse gases on the environment?
-Ways to reduce the impact include reducing the burning of fossil fuels, adopting renewable energy sources, and implementing energy-efficient practices.
What is the average global temperature without the greenhouse effect?
-Without the greenhouse effect, the average global temperature would be around -18 degrees Celsius, which is significantly colder than the current average.
How can individuals contribute to the solution of reducing greenhouse gas emissions?
-Individuals can contribute by adopting sustainable practices such as recycling, using public transportation, reducing energy consumption, and supporting policies that aim to reduce emissions.
Outlines
đż Understanding the Greenhouse Effect
The first paragraph introduces the concept of the greenhouse effect, which is a process where certain gases in Earth's atmosphere trap radiation, preventing it from escaping into space. The analogy of a greenhouse is used to explain how radiation from the sun passes through the atmosphere, is absorbed by the Earth's surface, and then some of it is trapped by greenhouse gases, keeping the Earth's surface warm. The paragraph emphasizes the role of greenhouse gases such as carbon dioxide, water vapor, methane, and fluorinated gases in this process. It also highlights the importance of these gases for life on Earth, as without them, the average global temperature would be too low to sustain life. The paragraph concludes by mentioning the impact of human activities, particularly the burning of fossil fuels, which emit carbon dioxide and contribute to the greenhouse effect.
đ„ Impact of Fossil Fuels on Greenhouse Gases
The second paragraph delves into the consequences of burning fossil fuels, which not only emit carbon dioxide but also other greenhouse gases. It points out that the increase in these gases is observable and alarming, as illustrated by a graph referred to as the 'Keeling Curve,' which shows a consistent rise in carbon dioxide levels in the atmosphere over the years. The paragraph also addresses the negative impacts of this increase, including the accelerated rate of extinction of plant and animal species. It ends with a teaser for the next video, promising to provide tips on how individuals can help mitigate the increase of greenhouse gases and become part of the solution to this environmental challenge.

Transcripts
so first define monolithic one algorithm
so on greenhouse effect it is a process
in which particular gases in the earth's
atmosphere trap the radiation and
negative molasses
now to better
understand from annual definition of
greenhouse effect let us go to the
definition or the concept now some
greenhouse now familiarity don't even
smart and they got plenty
so on greenhouse exams house-like
structure
so i'll concentrate some greenhouse
first in radiation
it will pass through the glass troops or
gas walls
[Music]
environmental system within the
greenhouse period
[Music]
um
[Music]
now let us relate the concept of a
greenhouse to the greenhouse effect
first the radiation
coming from the sun
passes through the earth's atmosphere
that time i only wind up earth surface
center then
some of the
radiation will be reflected back to
outer space
but some of the radiation
will be trapped
and kept close to the earth's surface
perov here's the question if the
greenhouse has gas that would act as
barriers so that heat will not be able
to escape
from the things uh
greenhouse effect
so what keeps that heat closer to the
earth's surface now vito papa
greenhouse gases so these greenhouse
gases are the particular gases which
absorb the reflected radiation coming
from the earth's surface and then
re-emits them back as heat or infrared
radiation now electromagnetism
i am carbon dioxide water vapor methane
fluorinated gases like
chlorofluorocarbons
okay now we understand along greenhouse
effect finally mechanism of greenhouse
effect and annoying greenhouse gases
which contribute to the greenhouse
effect so that next question is
and the answer is yes mahalaka and
greenhouse effect in fact
life will not be able to exist
if while on greenhouse gas to better
understand
an average global temperature crayon
i 15 degree celsius
average
15 degrees celsius if
while i'm greenhouse silver if whatever
greenhouse gas is natural
i'm gigging average global temperature a
negative eight million celsius that is
33 degrees lower
than what we have right now
um
or early 1800s
which
uses energy
that comes from burning of fossil fuels
now burning of fossil fuels
emit carbon dioxide
and also other greenhouse gases as well
so the more you burn fossil fuels the
more carbon dioxide is produced the more
greenhouse gases produce and we were
able to observe it increasing in fact
there was a curve a graph which showed
the increase of carbon dioxide
concentration in the earth's atmosphere
every year it was called the killing
curve you can observe that it is really
increasing throughout the years now that
heldua damien greenhouse gases are
atmospheric
increasing rates of extinction of flora
and fauna species
and there are also
[Music]
[Music]
to lower or stop the increase of
greenhouse gases i will be posting the
next video
about in which i will be giving many
tips on how you can help become part of
this solution
i know
