The document provides information about global climate change, including its causes, effects, and steps that can be taken to address it. It discusses how human activities that release greenhouse gases are the main driver of increased global temperatures. Effects of climate change mentioned include more frequent and intense heat waves, rising sea levels due to melting ice sheets and glaciers, and bleaching of coral reefs. Proxy data from tree rings, coral reefs, and ice cores can be analyzed to study past climate changes. Nations have adopted measures like the Kyoto Protocol to reduce emissions, while individuals can contribute through actions such as using renewable energy and reducing meat consumption.
Climate change, additionally called an Earth-wide temperature boost, alludes to the ascent in normal surface temperatures on Earth. A staggering logical accord keeps up that environmental change is expected essentially to the human utilization of fossil fills, which discharges carbon dioxide and other nursery gasses into the air. The gasses trap warm inside the climate, which can have a scope of consequences for biological communities, including rising ocean levels, extreme climate occasions, and dry seasons that render scenes more vulnerable to rapidly spreading fires. Climate change is statistical data of weather for a given period of time. As all living beings interact with environment, the weather plays a vital role is development and sustainability of all living beings. Climate change is a phenomenon that is going to occur even if humans didn't exist on this planet, we for the sake of development have accelerated the climate change.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Introduction
"We are living on this planet as if we have another one to go
to"
- Terry Swearingen
Climate change is a vast, interesting and also a common topic for all
higher secondary school students and so I hope this video helps you to
understand some concepts related to climatic changes. Climate change can
be explored in various disciplines in different ways. We will look at it
from the geographical perspective and how we can make use of this
knowledge in real life situations, as it is of paramount importance for
our planet, to make it more habitable and healthier.
Climaton the other hand refers to long term regional or even global
average of temperature, humidity and rainfall patterns over seasons, years
or decades.

No challenge poses a greater threat to human
generations other than CLIMATE CHANGE
7. 7
Climate change
It is a long-term change in the average weather patterns that have come to define
the earth's local, regional and global climates.
History of climate change
Variability in climate occurs all the time. The nineties decade of the last century
witnessed extreme weather events. The 1990s recorded the warmest temperature of the
century and some of the worst floods around the world. During the 1930s, severe
drought occurred in southwestern Great Plains of the United States, described as
the dust bowl. From about 1885-1940 world temperature showed an upward trend. After
1940, the rate of increase in temperature slowed down.
When we talk about climate changes, we refer to the natural fluctuations in the
climate. The temperatures have been rising faster, due to human activities and
natural causes too. The world has been getting warmer day by day. We are adding to
the natural greenhouse effect, with harmful gases from the industries, agriculture,
explosions and many other factors and in turn trapping more energy and increasing
the temperature. This is known as global warming too, though the term "climate
change" refers to the broader range of changes that are occurring on earth other
than encompassing global warming.
8. 88
Causes of climate change
The causes for climate change are many. Some causes of climate change are listed below :
Topography: This refers to the shape of the land. Latitudes and elevation ranges are one of the
factors that lead to fluctuation in surface temperatures. It can lead to local changes in climate.
Sea level: One of the influential factors affecting a region’s climate is the distance from the sea
and nearby water bodies. The surface temperatures in sea have an effect on land temperatures. Coastal
areas are cooler and wetter than internal areas. This leads to cloud formation when warm air from
these interior areas meets cool air from the sea.
Ocean currents: These can transfer heat energy from land to sea or vice versa, hence influencing the
temperature of the region.
Prevailing winds: Winds scatter specific air masses. The climate of a region can be dependent on the
direction of the wind as the wind from the humid region brings cool air while that from the dry region
brings hot air.
Milankovitch oscillations: Variations in the earth’s orbital characteristics around the sun and the
changes in the earth’s axial tilt affects the amount of isolation faced by earth and hence affects the
climate.
Human activities: Deforestation, an increase in the human population, pollution caused by the burning
of fossil fuels, emission from vehicles and industries.

IMPACT OF CLIMATE CHANGE AND
PROXY DATA
Global warming, its effects and proxy data for studying climate change
“
EFFECTS OF CLIMATIC CHANGE
10. 1010
Global warming
Global warming is the
effect of gases such as
carbon dioxide, methane
etc on the temperature of
the earth. It has led to
an increase in the heat
holding capacity of the
atmosphere which in turn
increases the
temperature..
11. 1111
Effects of global warming
1) Heat Waves
2) Heat Islands
3) Increase in sea level
4)Organisms
5) Melting of glaciers
at high altitudes and
snow in polar areas
12. 1212
1) Heat Waves
Increases the heat
holding capacity of the
atmosphere which in turn
increases the
temperature especially
during summers.
13. 1313
2) Heat Islands
Global warming serves as a
base from which heat waves
become much worse
especially in big cities
where the heat island effect
comes into play. Urban areas
heat up more readily because
of paved surfaces and
concrete constructions.
14. 1414
3) Increase in sea level
The global sea level rise is caused
due to the following :
1. Melting of land ice
2. Changes in the amount of water
stored on land.
3. Higher sea levels can lead to
deadlier cyclones and frequent
flooding of coastal areas. For
example, parts of Konkan coast,
southern Kerala and flooding of
cities and coastal communities
around Kutch in Gujarat.
15. 1515
4) Organisms
i) Around the world the jellyfish seem
to be reproducing heavily and
congregating in places where they were
never seen before. This is happening
because of warmer waters and changes in
the acidity level of the oceans.
ii) Spread of insects in newer regions
: Global warming will apparently
increase the number of mosquitoes as
higher temperature and humid conditions
provide a perfect breeding ground.
iii) Coral reefs : When temperatures
change, corals throw out the algae
living in their tissues. These algae
are responsible for their color.
Increase in temperature leads to
bleaching of corals and if prolonged
the corals perish.
16. 1616
5) Melting of glaciers and snow in
polar areas
The melting of ice is a very
natural process. But when
glaciers and icebergs melt at an
alarming rate, it becomes a cause
of concern. This phenomenon has
intensified in the 20th century
and will soon leave our planet
iceless. The main culprit is
human activity in the emission of
carbon dioxide and other
greenhouse gases. The earth's
retreating glaciers are evident
impacts as oceans and other water
bodies absorb more than 80% of
the earth's warmth, and glaciers
are mostly located near the poles
and higher altitudes. For example
the Gangotri glacier, one of the
largest in the Himalayas, has
retreated more than 850 meters
with a recession of 76 meters
from 1996 to 1999 alone.
17. 17
Proxy data for studying climate
change
Examples of proxy data
and how it helps to
analyse climate change
1)Coral reefs
2)Tree rings
3)Ice sheets
18. 1818
Coral reefs
Coral reefs form skeletons
by extracting calcium
carbonate from the ocean and
are very sensitive to
temperature which results in
a change in their density in
different temperatures.
Because of this sensitivity
they form rings every season
and by observation
scientists determine the
temperature or water or the
season in which the growth
of the reef took place.
19. 1919
Tree rings
Trees form different
widths of rings every
season and are heavily
affected by
environmental
conditions. By studying
the variation in these
rings scientists can
determine the climatic
conditions that were
present at that time.
20. 2020
Ice cores
These are samples taken
from the inside of the
ice sheets and have a
different texture
depending on the
climatic conditions.
These sheets from
Antarctica or Greenland
give information about
the climate of each year
the sheets were formed.

Climate change is the single biggest thing that humans have done to this planet.
The one thing that needs to be bigger is our movement to stop it.

STEPS TO TACKLE DRASTIC CLIMATE
CHANGES TO A CERTAIN EXTENT
22. 2222
1.Power your home with renewable sources of energy : Set up solar panels on
the roofs of your house. Now since this might not be convenient for
everybody, start by observing your electricity bill and start reducing the
AC usage, start using LED lights which consume less power, reuse items in
your house and use less plastic.
2.Reduce water pollution : Surprisingly reducing water pollution also helps
to lower CO2 emissions. You must be wondering why..... that's because it
takes large amounts of energy to pump, heat and treat your water. Start
spending less time in your shower singing , close the tap while brushing
your teeth and switch off water appliances after their use has been served.
3.More trees please ....let's go green : Plant as many trees in your
neighborhood as possible but don't forget to also take care of them. It
won’t make a difference if you plant a sapling and forget all about it
later.
4.Dietary habits: Reduce meat intake or better still go vegan: By reducing
your consumption of animal protein by half, you can cut your diet's carbon
footprint by more than 40%. If its difficult to go vegan or turn
vegetarian, at least become a 'flexitarian' and reduce your red meat
intake.
23. 2323
Measures opted by nations to tackle climate change
Other than the previously given measures, there are several measures adopted by
different countries to tackle climate change. For example, the Kyoto Protocol is
an international treaty that commits member countries to reduce greenhouse gas
emissions.
The Government of India has also taken important steps to combat climate change:
1.National Action Plan on Climate Change (NAPCC), 2008
2.National Adaptation Fund for Climate Change, (NAFCC)
3.National Clean Energy Fund (NCEF)
To conclude this topic, I would like to reiterate the fact that its imperative to
understand the complexities of the climate change process, its causes, its
disastrous effects and what can be done to tackle this alarming issue. Let's not
take this lightly and try to be responsible for our actions on our planet and
strive for a better world, a greener and healthier version for the future
generations....

Hello everyone, this is Rupali Shelar, student of DY Patil college of education, pimpri. There is always a first time to everyrhing.so here I am with my first video, made as part of our college activity.
It’s a grest opportunity, given by our princiopal and our inspiration , Dr Rekha Pathak maam and our subject in charge and guide Asst prod S D Bhosle mam taking into consideration the current pandemic situation and the need to learn online teaching strategies. I thank them for their constant guidance and support.
The topic that I have taken up is Global Climate Change from class 11 Geog textbook , Maharashtra state board. Now how you look at this topic and understand it , depends a lot on your perspective towards climatic changes. For me, it’s a topic of significance because of its environmental and global impact. Lets have a look…
Global Climate change is a vast topic…
It is a common topic covered in every school board and I hope this will help you to understand some main points related to this topic. First lets understand what is climate…as we all know and have studied in our previous classes, weather and climate are 2 different things. Climate is what you expect and weather is what actually happens. Weather is what happens in our atmoasphere at a given poimt and location , depending on factors like air pressure, temperature, humidity, wind speed and many other things. It refers to the local atmospheric conditions and is different in different parts of the world. Climate on the other hand describes what the weather is like over a long period of time in a specific area. Like for instance, we say that the climate of Mumbai is hot and humid while that of Kashmir is cold. That tells us how the weather conditions prevail in those areas for a longer duration. And we all need to understand that Earths climate is changing drastically and we better get serious about this issue.
Climate changes refers to the averages of measures that we use to predict weather conditions like precipiatation, temperature, humidity, sunshine, wind,etc. Now these changes have been fluctuating quite a lot due to human activities as well as natural causes. There is an increase in the temperatures all over the world,also known a global warming due to the increase in the level of air pollutants and greenhouse gases like CO2, methane, ozone and nitrous oxide. Increasing industrial activities and deforestation have also contributed to the increase in the temperatures. Climate change is not just ablut global wareming and there are other changes also that occur on earth , which are responsible for it.
Human activities or more specifically the greenhouse gas emissions generated by us are the leading cause of the rapidly increasing climate change. But there are some common causes too that contribute to this change. Lets have a look at some of them. Topography…it means the shape of the land. Climatic variations occur due to the difference in the height of a place and its latitudinal extent. For eg the climate for a mountainous region would be dufferent than for a plain region.
