Welcome to the Lorlonolo platform. In
0:02
this lesson, we are conducting an
0:04
in-depth review of the 2025-2026
0:05
midterm topics, past exam questions,
0:07
and detailed explanations for Global
0:09
Climate Change and Atmospheric
0:11
Disasters. This explanatory guide of
0:14
ours is essentially a deep dive for
0:16
your upcoming exam. As we discuss a
0:18
massive topic like climate change, we
0:20
will certainly not skip any details,
0:22
concepts, or those confusing question
0:24
patterns you have encountered in past
0:26
exams. We will build the logic and
0:29
cause-effect relationships of
0:30
everything together, step by step.
0:32
Alright, let's jump right into the
0:34
subject and take a look at our
0:35
wonderful study schedule. We have five
0:37
main headings on our agenda. Structure
0:39
of the atmosphere, past climates,
0:41
anthropogenic—that is, human-induced
0:43
—effects, climate diplomacy, and
0:45
finally, socioeconomic disasters. Let's
0:47
begin. Part 1. Structure of the
0:50
atmosphere and landform shaping. Let's
0:52
lay the foundation by looking at how
0:54
our world's perfect natural system
0:56
works. Now, think about this for a
0:58
moment. -18 degrees. Can you believe it
1:00
? If it weren't for our atmosphere's
1:03
famous natural greenhouse effect, the
1:04
world we live on right now would be
1:06
exactly -18 degrees. That is, colder
1:08
than the harshest winter, completely
1:10
frozen, an impossible place to live.
1:12
The system that saves us from this end
1:14
is the natural greenhouse effect that
1:16
keeps the heat coming from the sun
1:17
inside. By the way, a quick reminder:
1:19
our most abundant gas in the atmosphere
1:21
by quantity is nitrogen. Another
1:23
fascinating part of the business is the
1:24
troposphere layer. This is the layer
1:26
where all those storms break out and
1:27
which contains almost all of the water
1:29
vapor. Since it touches the ground,
1:31
heating also occurs from the bottom up.
1:33
In other words, as you go up in this
1:35
layer, you directly feel the sharp cold
1:36
of the air. Of course, what we call
1:39
climate doesn't just affect the air or
1:40
the plants. It literally carves the
1:42
mountains and valleys we walk on,
1:44
meaning geomorphology as well. The
1:46
atmosphere slowly erodes rocks through
1:48
mechanical and chemical processes. But
1:50
look, this is a very critical detail
1:51
for exams. This is not something that
1:53
happens instantaneously or in a few
1:54
centuries. We are talking about an
1:56
unbelievably slow process that lasts
1:58
for tens of thousands of years. We call
1:59
these landforms that bear the signature
2:02
of that specific climate after this
2:04
massive time frame zonal forms or
2:06
morphoclimatic forms. Part 2. Past
2:09
climates and natural cycles. We are
2:11
going back in time to periods when
2:13
humanity wasn't even on the horizon and
2:15
the Earth was spinning in its own
2:16
rhythm. Well then, when there isn't a
2:18
thermometer or a satellite around, how
2:20
do we know the weather from thousands
2:21
of years ago? This is where nature's
2:23
own secret archive, namely
2:24
paleoclimatology, comes into play.
2:27
Cores taken from glaciers, sediments on
2:29
lake bottoms, fossils, pollen analyses,
2:31
and the dendroclimatology method that
2:33
examines tree rings. We call these
2:35
proxy data. When talking about modern
2:37
records, there is no need to go too far
2:38
. For example, in the 11th. century,
2:40
even during the period when the Turks
2:41
migrated to Anatolia, there were
2:42
naturally no meteorological stations.
2:44
To understand the weather of those days
2:45
, we rely entirely on these silent
2:47
records of nature. And these wonderful
2:49
records show us in a magnificent way
2:51
how natural cycles in deep time work.
2:54
Let's go back to the very beginning, to
2:56
the Carboniferous period within the
2:57
Paleozoic era. The world was so hot and
2:59
humid that the foundation of the giant
3:01
coal beds we burn today was laid by the
3:03
forests of those times. 19th. We said
3:05
we looked at natural records in the
3:06
century. 20th. When we come to the
3:08
century, a revolutionary discovery was
3:10
made. Milankovitch proved that
3:12
deviations in Earth's orbit and changes
3:14
in its axis created those great ice
3:16
ages. In other words, it was
3:18
definitively proven that the global
3:19
climate is already in a state of
3:21
constant change due to natural causes.
3:23
Chapter 3. Anthropogenic effects and
3:25
global warming. We are moving into that
3:27
dangerous phase where things leave
3:29
their natural cycle and become messed
3:30
up by human intervention. Put aside
3:33
that slow, millions-of-years-long
3:34
natural change we just talked about.
3:36
With the Industrial Revolution, we are
3:38
facing an incredibly fast and jarring
3:40
anthropogenic, or human-caused, change.
3:42
We are burning fossil fuels non-stop.
3:44
We are cutting down forests. Let's
3:46
immediately correct a common trap here.
3:47
Reforestation efforts never increase
3:49
greenhouse gases. On the contrary, it
3:51
protects us by absorbing these gases.
3:53
However, when we destroy forests and,
3:55
on top of that, emit sulfur and
3:56
nitrogen from factories, they combine
3:58
with water vapor in the sky and rain
4:00
down on us as acid rain. The damage
4:02
this causes to nature and structures is
4:04
truly terrifying. So, how is this great
4:07
warming changing the map? Let's get to
4:09
one of the most painful questions you
4:11
might face on an exam. Does global
4:13
warming expand the area of the polar
4:14
climate? Absolutely not. The logic is
4:17
actually quite simple. As the world
4:19
runs a fever, mountain glaciers melt
4:21
and the poles warm up. How can an area
4:22
that is melting and disappearing expand
4:24
? On the contrary, global warming
4:26
causes the polar climate zone to shrink
4:28
or diminish. Definitely write this
4:30
piece of information in a corner of
4:32
your mind. Chapter 4. Climate diplomacy
4:35
. Let's see what path governments are
4:36
taking in the international arena to
4:38
stop this crisis. Following this whole
4:40
picture, the world finally began to
4:42
come together. The first international
4:44
acknowledgment that the environmental
4:46
crisis was a global problem happened at
4:48
the 1972 Stockholm Conference. This was
4:51
a turning point. The process that
4:52
started there has extended to the 2015
4:54
Paris Agreement, which we frequently
4:55
hear about today. The goal is quite
4:57
strict and clear. We must keep global
4:59
warming within the 1.5 to 2-degree band
5:01
. At the heart of all this diplomatic
5:03
battle lies the famous principle of
5:05
sustainable development. In other words
5:07
, grow your economy and meet your needs
5:09
today, but do not consume nature in a
5:10
way that leaves no world for future
5:12
generations. Chapter 5. Socio-economic
5:15
disasters. Let's look at how these
5:17
macro-level events return as a shock
5:19
wave to local economies and our daily
5:21
lives. This table shows us that the
5:24
issue is not just nature, but directly
5:26
our wallets. When precipitation is
5:27
disrupted, agriculture immediately
5:29
collapses. Winter tourism takes heavy
5:30
hits because it doesn't snow, and
5:32
coastal tourism suffers as sea levels
5:34
rise. However, there is a detail you
5:36
will often encounter in exams to test
5:37
your attention. Faith tourism. Faith
5:40
tourism, which involves visiting sacred
5:42
sites, is almost entirely independent
5:44
of the weather or climate. Therefore,
5:46
its level of being affected by this
5:47
crisis is the most minimal compared to
5:49
others. In city centers, the situation
5:51
can become much more suffocating. Not
5:53
only do urban heat islands, where
5:55
concrete and asphalt trap heat like an
5:57
oven, exist, but local precipitation
5:59
balances are also completely thrown off
6:00
. Particulate pollution, with dust,
6:02
pollen, and soot flying in the air,
6:04
directly hits our respiratory tracts.
6:06
And there is that invisible but very
6:08
exhausting acoustic pollution, which is
6:10
city noise. Make no mistake. Acoustic
6:12
pollution doesn't keep people awake or
6:14
improve focus. On the contrary, it
6:16
strains the nervous system. It leads to
6:17
extreme stress and severe loss of focus
6:19
. Perhaps the most insidious link in
6:22
the chain of disasters is drought.
6:23
Drought does not happen all at once. It
6:25
comes step by step. In the first stage,
6:27
regular rainfall simply decreases. We
6:29
call this meteorological drought. If
6:31
this process drags on for weeks, months
6:33
, and starts draining our lakes and
6:35
rivers, the danger bells are truly
6:37
ringing. By the time the waters dry up,
6:39
the crisis has escalated to
6:41
hydrological drought. Visualize clearly
6:43
that meteorological drought is always
6:45
the first step. As we wrap up our guide
6:48
, I must warn you about the biggest and
6:49
most classic trap waiting for you on
6:51
the exam. Avalanches, storms, droughts,
6:53
floods, and even the famous El Niño
6:55
that creates weather anomalies
6:57
worldwide. These are all atmospheric
6:59
and climatic events. However,
7:01
earthquakes, which occur due to the
7:03
breaking of the Earth's crust, are
7:05
purely and solely geological events.
7:08
Frankly, earthquakes have no connection
7:10
to the atmosphere, weather, or global
7:12
climate change. While climate crises
7:14
rage on the surface, tectonic plates do
7:16
their own thing. Never let this vital
7:19
distinction slip your mind. Climate
7:21
change is not just a theoretical topic
7:23
left in textbooks. It is our most
7:24
critical reality that directly shapes
7:26
all of our futures. So, what kind of
7:28
world will be left after everything we
7:30
have learned? To solve the past exam
7:33
questions for this course and year that
7:35
