IMPACT OF GLOBAL WARMING ON AQUATIC FLORA AND FAUNAMahendra Pal
A rise in temperature as small as 1° C could have important and rapid effects on the geographical distributions and mortality of some organisms. The more mobile species should be able to adjust their ranges over time, but less mobile and sedentary species may not.There are many factors that can cause a warming of our climate; for example, more energy from the sun, large natural events such as El Nino or an increased greenhouse effect. Rising temperatures can directly affect the metabolism, life cycle, and behaviour of marine species. For many species, temperature serves as a cue for reproduction. Clearly, changes in sea temperature could affect their successful breeding. The number of male and female offspring is determined by temperature for marine turtles, as well as some fish and copepods (tiny shrimp-like animals on which many other marine animals feed). Changing climate could therefore skew sex ratios and threaten population survival.

Environmental conditions play a key role in defining the function an.pdfanandhomeneeds
Environmental conditions play a key role in defining the function and distribution of plants, in
combination with other factors. Changes in long term environmental conditions that can be
collectively coined climate change are known to have had enormous impacts on plant diversity
patterns in the future and are seen as having significant current impacts. It is predicted that
climate change will remain one of the major drivers of biodiversity patterns in the future.
The Earth has experienced a constantly changing climate in the time since plants first evolved. In
comparison to the present day, this history has seen Earth as cooler, warmer, drier and wetter,
and CO2 (carbon dioxide) concentrations have been both higher and lower. These changes have
been reflected by constantly shifting vegetation, for example forest communities dominating
most areas in interglacial periods, and herbaceous communities dominating during glacial
periods. It has been shown that past climatic change has been a major driver of the processes of
speciation and extinction. The best known example of this is the Carboniferous Rainforest
Collapse which occurred 350 million years ago. This event decimated amphibian populations
and spurred on the evolution of reptiles
Greenhouse effect - the mechanism
The sun radiates solar energy on earth. The larger part of this energy (45%) is radiated back into
space. Greenhouse gases in the atmosphere contribute to global warming by adsorption and
reflection of atmospheric and solar energy. This natural phenomenon is what we call the
greenhouse effect. It is agreed that the greenhouse effect is correlated with global temperature
change. The primary greenhouse gases in the Earth’s atmosphere are water vapor, carbon
dioxide, methane, nitrous oxide, and ozone
Mechanism of global warming:
i. The incoming radiation from the Sun is mostly in the form of visible light and nearby
wavelengths, largely in the range 0.2 – 4 1m, corresponding to the Sun’s radioactive temperature
of 6,000 K. Almost half the radiation is in the form of “visible” light, which our eyes are adapted
to use.
ii. About 50% of the Sun’s energy is absorbed at the earth’s surface and the rest is reflected or
absorbed by the atmosphere. The reflection of light back into space – largely by clouds – does
not much affect the basic mechanism; this light, effectively, is lost to the system.
iii (a) Earth absorbs most of the sunlight it receives; The absorbed energy warms the surface; (b)
Earth then emits the absorbed light’s energy as infrared light; (c) greenhouse gases absorb a lot
of the infrared light before it can leave our atmosphere; (d) being absorbed slows the rate at
which energy escapes to space; and (e) the slower passage of energy heats up the atmosphere,
water, and ground. By increasing the amount of greenhouse gases in the atmosphere, humans are
increasing the atmosphere’s absorption of infrared light, thereby warming Earth and disrupting
global climate patterns.

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.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

7. temperature can have serious effects on climate
conditions & weather changes. This affect the frequency
& severity of storms hurricanes & tornados distort
seasons duration, increase cloud cover, change
precipitation levels & wind patterns. Warmer sea surface
temperature will cause frequent storms & hurricanes
along the gulf coasts & southeastern Atlantic. A number
of scientist have agreed that global warming is a serious
warming is happening more quickly in same parts of the
world than others.
The formation of the Earth took places around 4.6
Billion years ago & since then its temperature is
changing. It has been warmer in the past than it is today
& at time much colder. But the most alarming fact is the
speed at
8. which the Earth is now heating up. Before the first time
history humans are the main factor of the Earth’s
changing climate or as we have named it ‘GLOBAL
WARMING’.
10. CAUSES OF GLOBAL WARMING
1. Greenhouse Effect :
The greenhouse effect was discovered on 1896
and is a natural process. To support life for billions of
years it has kept our planet warm enough. But more
heat is trapped in the atmosphere as the amount of
greenhouse gases increases. The earth is getting
hotter as the natural process has spread up.
12. 2.
LIFE IN CITY
It is not just that there are more people than ever
before. It is also how we choose to live that puts a
strain on our planet. Life is comfortable and
convenient in large cities. But the energy this lifestyle
needs has a high environmental cost.
14. 3. INCREASE POPULATION :
One of the greatest factors in global warming is the
in increasing number of people on the earth. During
the past 100 years the world's population has grown
nearly four times larger. This has led to a massive rise
in the levels of greenhouse gases in the earth's
atmosphere.
The growth of towns and cities is called urban
spread. This takes up land that could be used for food
crops and also destroys the places where plants and
animal live.
17. 4.
AIR POLLUTION :
There are different kinds of pollution. Some visible,
some invisible, that contribute the global warming.
Carbon dioxide a greenhouse gases is the main
pollutant that is warming earth. Though living things
emit carbon dioxide when they breathe, carbon
dioxide is widely considered to be a pollutant when
associated with cars, planes, power plants and other
human activities that involve the burning of fossil.
20. 5. Deforestation :
Deforestation is clearing earth's forests on a
massive scale often resulting in damage to the quality
of the land. Forests still cover about 30% of the
world's land area.
Forests are cut down for many reasons but most of
them are related to money or to peoples need to
provide for their families. The biggest driver of
deforestation is agriculture.
Deforestation has many negative effects on the
environment. The most dramatic impact is a loss of
habitat for millions of speckles. It also drives climate
change. Forest soils are moist, but without protection
from sun blocking tree cover they quickly dry out.
The quickest solution to deforestation would be to
simply stop cutting down trees.
22. OTHER CAUSES OF GLOBAL WARMING
1. Ozone Layer :
2. Methane Gas :
3. Temperature :
4. Pollution :
23. Ozone layer
The ozone layer is a layer in Earth's atmosphere
which contains relatively high concentrations of ozone
(O3). This layer absorbs 97–99% of the Sun's high
frequency ultraviolet light, which is potentially
damaging to the life forms on Earth. It is mainly
located in the lower portion of the stratosphere from
approximately 20 to 30 Km (12 to 19 mi) above Earth,
though the thickness varies seasonally and
geographically. The ozone layer was discovered in
1913 by the French physicists Charles Fabry and
Henri Buisson. Its properties were explored in detail
by the British meteorologist G. M. B. Dobson, who
developed a simple spectrophotometer (the
24. Between 1928 and 1958 Dobson established a
worldwide network of ozone monitoring stations,
which continue to operate to this day. The "Dobson
unit", a convenient measure of the columnar density of
ozone overhead, is named in his honor.
30. EFFECTS OF GLOBAL WARMING:
1. Ice is melting worldwide, especially at the earth’s
poles. This includes mountain glaciers, ice sheets
covering West Antarctica & Greenland & Arctic sea
ice.
2. Sea level rise become faster over the last century.
Sea
levels are expected to rise between 7 & 23
inches by
the end of the century & continue
melting at the poles could add between 4 & 8 inches
3. Hurricanes & other storms are likely to become
stronger
4. Species that depends on the one another may
become out of sync.
31. 5. Floods & droughts will become more common.
Rainfall in Ethiopia, where droughts are already
common, could
decline by 10% over the next 50
years. Less fresh water will be available.
6. Some diseases will spread such as malaria carried
by mosquitoes.
7. Ecosystem will change – some species will move
further & could become extinct.
33. ACID RAIN :
Acid rain describes any form of precipitation with
high levels of nitric & sulfuric acids. It can also occur in
the form of snow, fog & tiny bits of dry material that
settle to earth.
Ratting vegetation & erupting volcanoes release
some chemical that can cause acid rain but most acid
rain falls because of human activities. The biggest
culprit is the burning of fossil fuels by coal burning
power plants factories & automobiles.
Acid rain has many ecology but none is greater
than its impact on lakes, streams, wetlands & other
aquatic environments. Acid rain makes water acidic &
causes them to absorb the aluminum that makes its
way from soil into lakes & steams. This combination
34. crayfish clams, fish & other aquatic animals
The only way to fight acid rain is by curbing the
release of the pollutants that cause it.
35.
36. DISAPPEARING WORLD:
Many nations have laws offering protection to
conservation reliant species: for example, forbidding
hunting, restricting land development or creating
preserves. Before greenhouse gases and global
warming species were able to survive in their natural
habitat. However the rapid increase of climate change
has put animals at risk of becoming extinct. As global
warming continues, species are no longer able to
survive and their kind starts to deteriorate. This is a
repeating cycle that is starting to increase at a rapid
rate because of climate change therefore landing
many species on the endangered species list.
46. ECO-FRIENDLY HOMES:
Our home release almost a third of the
greenhouse gas we produce. The good news is that
there are several ways ranging from now our homes
are built to the way we live inside them. By which we
can reduce the amount of greenhouse we make.
48. Preservation of Forests and Oceans:
Carbon is removed & trapped by the forest &
oceans as part of their natural process. In turn they
can decrease the amount of carbon dioxide in the
atmosphere & limit the power of the greenhouse
effect. Humans have upset earth’s natural balance by
damaging forest polluting oceans & fossil fuels. Due to
this reason we must work together to protect our
precious trees & seas.
50. LESS WASTE:
A large amount of our household waste ends up on
solid waste landfills. These enormous trash dumps
release methane a greenhouse gas as they vote. One
easy was to cut the methane that is released is to
reduce the amount of trash you produce & recycle as
much as possible of what is left.
52. What can you do Prevent Global Warming?
1. Recycle as much waste as is possible by sorting
your
trash.
2. Compost all your food scraps for use in your
garden.
3. Take used glass bottles & jars to a recycling
centre.
4. Save & reread old comics & amazing or give them
to a friend.
5. Donate old toys & cloths to thrift stores.
53. CONCLUSION:
One Green Day
By saving water & electricity each one of us can
held fight climate change. You can go even fate a
difference. The clothes you wear the foods you eat &
the product you use all contribute to your personal
carbon foot print simple everyday decision can make
a huge difference to the amount of the greenhouse
gas that your lifestyle contributes to our atmosphere.
