We are the students of Ahsanullah University of Science And Technology from civil Engineering department .We have prepared a presentation for our Environmental Engineering lll course to explain global warming and climate change.Global Warming and Climate Change is hot topic nowadays .So this presentation was made to discover main causes behind this situation . Is Anthropogenic or natural?? In this presentation we have tried to explain this .
The Earth’s climate is dynamic and characterised by trends, aberrations and quasi-periodic oscillations varying over a broad range of time-scales [1], which are governed by external (extraterrestrial systems) and/or internal(ocean, atmosphere and land system). Trends are largely controlled by plate tectonics, and thus to change gradually on million year time scale. Aberrations occur when the certain thresholds are passed and are manifested in the geological record as the unusual rapid (less than a few thousands of years) or extreme change in climate. The quasi-periodic oscillations are mostly astronomically paced; they are driven by astronomical perturbations that affect the earth’s orbit around the sun and the orientation of earth’s rotation axis with respect to its orbital plane. These perturbations are described by the three main astronomical cycles: eccentricity, precession and obliquity, which together determine the spatial and seasonal pattern of insolation received by the earth [2], eventually resulting in climatic oscillations of ten to hundreds of thousands of year [3].Sun being the main source of energy for the earth system controls the climate of it. Variation in solar activity and cosmic ray intensity has direct influence over climatic features such as cloudiness, temperature and rainfall [4]. Volcanic eruptions also force all elements of the climatic systems up to a varying degree but producing long term climatic signals in the ocean. The cumulative volcanic cooling effect at present offsets about one third of anthropogenic warming [5].Other than these causes paleoclimatologists also relates the past climate changes with movement of solar system[6], interplanetary dusts and influence of asteroids[7].However the recent variability in climate what earth is experiencing is unlikely due to any of the individual above factors rather it is due to the compound effect of complex interactions of all the natural as well as anthropogenic forcings.

Climate is a long term pattern of weather. and we humans are continuously disturbing our climate just because of some pathetic reasons.
There are many Human are natural factors responsible for climate change.
This will help you in identifying the factors responsible for Climate Change.
Please try to eradicate factors of climate change. Otherwise it will make this environment deadly for us and for our coming generations.
Warming is believed to be caused by increasing concentrations of greenhouse gases produced by human activities such as the burning of fossil fuels and deforestation. The effects of an increase in global temperature include a rise in sea levels and a change in the amount and pattern of precipitation, as well a probable expansion of subtropical deserts.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
2. Climate is the average weather usually taken over a 30-year time period for a
particular region and time period. Climate is long term.
Weather is what is happening in the atmosphere on any given day, in a specific place.
Weather is short term.
Climate system:
• Atmosphere: The atmosphere covers the Earth. It is a thin layer of mixed gases
which make up the air we breathe. This thin layer also helps the Earth from
becoming too hot or too cold.
• Oceans: Oceans cover about 70 percent of Earth's surface. Their large size and
thermal properties allow them to store a lot of heat.
• Land: Land covers 27 percent of Earth's surface and land topography influences
weather patterns.
• Ice: Ice is the world's largest supply of freshwater. It covers the remaining 3
percent of Earth's surface including most of Antarctica and Greenland. Ice plays an
important role in regulating climate, because it is highly reflective.
• Biosphere: The biosphere is the part of Earth's atmosphere, land, and oceans that
supports any living plant, animal, or organism. It is the place where plants and
animals, including humans, live.
2
3. The atmosphere, or the layer of air that surrounds the earth protects life on earth by
absorbing the suns energy and keeping the earth warm. This is called the
Greenhouse effect.
Certain gases in the atmosphere are special in a way, in that they can trap the suns
heat. These gases include carbon dioxide and water vapor, among others. These
gases are generally called heat trapping gases or greenhouse gases.
3
4. The Industrial Revolution, which was the transition to new manufacturing processes
in 1760 to sometime about 1840, brought about some unexpected changes to the
atmosphere.
The Industrial revolution moved us away from hand production methods to
machines, new chemical manufacturing, iron production processes, improved
efficiency of water power, the increasing use of steam power, and the development
of machine tools. But more concerning is that it also included the change from wood
and other bio-fuels to coal and later other fossil fuels.
Burning of these fuels releases carbon dioxide and other heat trapping gasses into the
atmosphere. And so the rate at which these gases are being release since the
Industrial Revolution is higher than ever before.
4
5. •The pre industrial level of carbon dioxide was about 280ppm; The 2016 approx. 409 ppm
•About 40% of these emissions to date have remained in the atmosphere
•The rest was removed from the atmosphere and stored on land (in plants and soils) and in the ocean.
•The ocean has absorbed about 30% of the emitted anthropogenic CO2, causing ocean acidification.
•About half of the anthropogenic CO2 emissions between 1750 and 2011 have occurred in the last 40
years
Now not only are we emitting more heat trapping gases (i.e. greenhouse gases), such as carbon dioxide
into the atmosphere, but we are also destroying forests (deforestation) and polluting oceans, two
systems that help remove carbon dioxide from the atmosphere.
So in effect, we have increased our carbon footprint, that is the amount of carbon dioxide and other
carbon compounds released due to the use of fossil fuels.
It therefore becomes obvious that the overall amount of carbon dioxide now reaching the atmosphere
will continue to increase as these activities continue.
5
6. Ocean Acidification - Once dissolved in seawater, CO2 reacts with water, H2O,to form
carbonic acid, H2CO3:CO2 + H2O ↔ H2CO3. Carbonic acid dissolves rapidly to form H+
ions (an acid) and bicarbonate, HCO3-(a base). Seawater is naturally saturated with
another base, carbonate ion (CO3
−2) that acts like an antacid to neutralize the H+,
forming more bicarbonate. The net reaction looks like this: CO2 + H2O + CO3
−2
→ 2HCO3-
As carbonate ion gets depleted, seawater becomes under-saturated with respect to
two calcium carbonate minerals vital for shell-building, aragonite and calcite.
6
7. Total annual anthropogenic greenhouse gas (GHG) emissions (gigatonne of CO2-
equivalent per year, GtCO2-eq/yr) for the period 1970 to 2010 by gases
• Forestry and Other Land Use (FOLU)
• fluorinated gases covered under the Kyoto Protocol (F-gases).
• Pound for pound, the comparative impact of CH4 on climate change is over 20
times greater than CO2 over a 100-year period. However, Methane's lifetime in the
atmosphere is much shorter than carbon dioxide
• Carbon dioxide equivalency is a quantity that describes, for a given mixture and
amount of greenhouse gas, the amount of CO2 that would have the same global
warming potential (GWP), when measured over a specified timescale (generally,
100 years).
Today's CO2 concentration is the highest in 15 million years.
7
9. Global warming
• Each of the last three decades has been successively warmer at the Earth’s surface
than any preceding decade since 1850.
• The period from 1983 to 2012 was likely the warmest 30-year period of the last
1400 years in the Northern Hemisphere, where such assessment is possible
• The globally averaged combined land and ocean surface temperature data as
calculated by a linear trend, show a warming of 0.85 [0.65 to 1.06] °C over the
period 1880 to 2012. the average global temperature for 2016 was 0.9 °C above
pre-industrial levels.
• Sea surface temperatures in the Caribbean are projected to warm, perhaps by up
to 2oC or higher by the end of the century.
9
10. Sea level rise
• Over the period 1901 to 2010, global mean sea level rose by 0.19 [0.17 to 0.21] m
(i.e. over 7 inches)
• The rate of sea-level rise since the mid-19th century has been larger than the
mean rate during the previous two millennia
• Caribbean sea levels are projected to rise by up to 0.24 m (i.e. Over 9 inches) by
mid century. Sea level rise is not the same everywhere – for example, sea level in
Guyana is projected to be twice that of the regional level.
10
11. Ocean Acidification
• Since the beginning of the industrial era, oceanic uptake of CO2 has resulted in
acidification of the ocean;
• the pH of ocean surface water has decreased by 0.1, corresponding to a 26%
increase in acidity, measured as hydrogen ion concentration
11
12. More intense storms – compounded by sea level rise
GCMs (global) show a median decrease of up to 22% for annual rainfall. While the
RCM (regional) suggests a decrease of up to 57%.
The warming trend is expected to continue. The country is projected to be warmer by
up to 1.2 oC by the 2030s, 2.1 oC by the 2060s, and 3.6 oC by the end of the century.
12
13. Tourism is Saint Lucia's main source of jobs and income - accounting for 65% of GDP -
and the island's main source of foreign exchange earnings.
13
14. Food security is important as an independent country, else the country becomes
highly dependent on the outside world. Everything has to be imported.
Being food secure is the situation where there is reliable access to a sufficient
amount of affordable, nutritious food.
14
15. • A small positive anomaly of 1-2 degrees C for 5-10 weeks during the summer
season will usually induce bleaching.
• 2005 bleaching event resulted after prolonged warming period (about 1 degree C).
Corals' reproductive organs are also damaged by warmer water whether they
bleach or not - they produce many fewer eggs and testes in warmer water (e.g.,
when water temperatures are > 30 C).
• Surveys conducted in Saint Lucia show that fifty to eighty percent of corals along
the west coast have been bleached. There was also adecline in white sea urchins –
no recruitment; and decline in dolphin fish (mahi mahi; dowad) catch.
• Percent of visitors in Saint Lucia classified as visiting at least in part due to the coral
reef: 25% (World Resources Institute, 2005)
• Coral Reef-associated Tourism and Recreation (US$160 – 194 M), Coral Reef-
associated Fisheries (US$.5 –.8 M), Shoreline Protection by Coral Reefs - avoided
damages – 2007 (US $28 – 50 M): Total: US$188.5 – US$244.8M per annum (World
Resources Institute, 2005)
• Changing sea conditions could also be responsible for the increase in Sargassum
(seaweed) currently affecting fishing boats and possible impacting fisheries such as
the flying fish.
15
17. Small islands were fighting to ensure that the increase in temperature does not
surpass 1.5 degrees C above pre-industrial levels. However, many others were
content with agreeing to a goal of 2.0 degrees C. The science shows that even with a
warming of 1,5, small islands and other unique and threatened systems stand to be
negatively impacted.
Note that these predictions do not take into account the current stresses on the
environment such as environmental pollution; and as such, the levels of impact
depicted in this figure are likely higher than predicted.
According to a UNEP (2000) report, about 15,000 tons of nitrogen enters the
Caribbean sea from untreated sewage and non-point runoff from agriculture. This
same report, indicates that about 300, 000 tons of solid waste end up in waterways
and ultimately into the Caribbean Sea.
