Weather refers to short-term conditions for a limited area that can change rapidly, while climate describes average weather conditions over longer periods of time spanning many years. Climate is influenced by both abiotic factors like latitude and biotic factors such as plant transpiration. Greenhouse gases in Earth's atmosphere like carbon dioxide, methane and nitrous oxide are essential for trapping heat and maintaining a suitable temperature, but human activities that release additional greenhouse gases are causing global warming. Evidence of a changing climate comes from melting glaciers, tree rings, shifting animal and plant ranges, and increasing temperatures documented in many countries. Reducing greenhouse gas emissions and conserving energy in transportation, buildings, appliances, and water use can help address climate change.
“Change is the Law of Nature”.Climate Change is a reality. It has changed in Past, is changing in Present and will change in Future. The variation and shifts in weather conditions over space and time of different scales and magnitude resulting into
changes of Climatic Type is defined as Climate Change.
The factor that affect climate are,Continental drift,Variation in the earth’s orbit,Plate tectonics,Volcanic activity,Ocean currents,Greenhouse Gases,Atmospheric Aerosols etc. It effect climate in different ways such as Higher Temperatures,Changing Landscapes,Wildlife/Ecosystem at Risk,Ocean acidification /Rising Seas level,Increased Risk of Drought, Fire and Floods,Intensified Storms and Increased Storm Damages,Illness and Disease,Economic Losses,Agriculture Productivity/Food Security etc.
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 .

Historical Geography expert John Slifko, PhD, presents a brief overview of the History of Climate Change over the years including new research and discoveries up to the 2013 year
Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years). Climate change may refer to a change in average weather conditions, or in the time variation of weather within the context of longer-term average conditions.
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.

The Earth is warming. Earth's average temperature has risen by 1.5°F over the past century, and is projected to rise another 0.5 to 8.6°F over the next hundred years. Small changes in the average temperature of the planet can translate to large and potentially dangerous shifts in climate and weather.

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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.

Climate change ppt
1. LETS DO SOME CASE STUDY……
First of all, you should know
that weather and climate
are not the same thing.
2. WEATHER IS:
• Short term
• Limited area
• Can change rapidly
• Difficult to predict
WEATHER is what’s
happening outside your
window right now.
3. CLIMATE IS:
• Long term
• Wide area
• Seasonal
changes
• Measured over
long spans of
time
CLIMATE is the
average of many years
of weather observation.
4. Climate is affected by many factors
ABIOTIC FACTORS:
Latitude
Altitude
Ocean Currents
Topography
Solar Radiation
Evaporation
Orbital Variations
Volcanic Activity
BIOTIC FACTORS:
Transpiration
Respiration
Photosynthesis
Decomposition
Digestion
5. Greenhouse Gases are essential to our climate
http://www.larryjzimmerman.com/wproblems/warming/greenhouse.gif
6. Planets with very little
greenhouse effect are either very
cold…
Pluto’s average temperature is –370° F
http://www.windows.ucar.edu/tour/link=/pluto/statistics.html
7. On Mars, there is about a 300 degree F difference between
high and low temperatures
…or they have huge temperature
swings from day to night.
(http://quest.nasa.gov/aero/planetary/mars.html )
8. Planets with abundant
greenhouse gases are very hot
The average temperature on Venus is about 855° F!
http://www.windows.ucar.edu/tour/link=/venus/statistics.html
9. …which is just right…
…for the moment, anyway.
…and then there’s Earth….
11. With no greenhouse gases at all in its
atmosphere, scientists estimate that Earth’s
average atmospheric temperature would be
about -18° C, or about 0°F
http://plaza.ufl.edu/knhuang/project2/cause.html
12. The greenhouse gas content
of the atmosphere is being
altered by human activity.
The result of this change is
global warming.
14. Glaciers are melting away
worldwide
Agassiz Glacier,
Montana, in
1913…
Pasterze
Glacier,
Austria, in
1875…
…and in 2005
…and in 2004
15. Ice cores yield information and
actual samples of Earth’s past
atmosphere
www.daviesand.com/
16. Tree ring data show a
warming trend
www.accesstoenergy.com
17. Animal and plant life is
changing
2/3 of European butterfly
species studied have
shifted their ranges
northward by as much as
150 miles. (Parmesan, 1996;
Parmesan et al., 1999)
An analysis of the
distributions of
British birds found
that many species
have moved north by
an average of 18.9
km. (Thomas et al, 1999)
At Boston's Arnold
Arboretum, plants are
flowering eight days
earlier on average than
they did from 1900 to
1920. (Primack et al,2004)
18. Climate change seems to
accelerating
Each of the 48 continental states experienced above-normal
annual temperatures in 2006. For the majority of states, 2006
ranked among the 10 hottest years since 1895. ( NOAA)
19. More Greenhouse Gases Mean a Warmer
Earth
www.stuffintheair.com/global-energy-balance.html
21. Carbon Dioxide
In the distant past, the
Earth was much warmer.
High levels of Carbon
Dioxide in the atmosphere
fueled lush growth, some
of which was stored in the
form of fossil fuels.
22. www.epa.gov/climatechange
Carbon Dioxide in Earth’s
atmosphere has risen by
about 30% since the
beginning of the industrial
revolution. Most of the
increase is due to the
combustion of fossil fuels,
which releases the long-
stored CO2 back into the
atmosphere.
25. First we must admit that climate
change is everyone’s problem. No
agency, government, or scientist
can “fix it” for us. We are all in
this together.
We got here because of our
lifestyle. So our lifestyle has to
change.
Here’s what you can do…
What can be done?
26. •Install programmable thermostats.
•Check and repair weather stripping on doors
and windows.
•Adjust your clothing instead of the thermostat.
•Keep furnace and AC filters clean.
•Consider closing off unused rooms.
•Install insulated drapes.
•Plant deciduous trees on the sunny side of your
home.
Heating and Cooling
What other ways can you conserve heat and AC?
27. Conserve Hot Water
•Take shorter showers.
•Install low flow shower heads.
•Install a blanket on your hot water
heater.
•Insulate hot water pipes.
•Wash laundry in cold water.
•Only run the dishwasher if it’s full.
•Fix leaky faucets
What other ways can you cut down on hot water use?
In the average home, 17% of energy is used to heat
water. http://www.eia.doe.gov/kids/energyfacts/uses/residence.html
28. •Plan ahead – do several errands in a single trip.
•Walk or bike. It’s healthier anyway.
•Clean out the junk in the trunk. Lighter cars get better
mileage.
•Make sure your engine is properly tuned.
• Keep your tires properly inflated.
•Carpool or ride the school bus.

•Consider a smaller car or a hybrid for your next
vehicle.
Conserve in the Car
What other ways can you use less gas?
29. •Unplug chargers for cell phones and
other appliances when not in use.
•Get in the habit of turning lights and
appliances off.
•Vacuum the coils on the back of the
fridge monthly.
•Change to compact fluorescent
bulbs.
•Make your next computer a laptop.
•Install timers or motion sensors on
outdoor lights.
Conserve Electricity
What other ways can you conserve electricity?
30. •Recycle and buy recycled products.
•Choose products that have less packaging.
•Reuse, repair, or donate.
•Don’t buy it unless you really need it.
•Carry cloth bags when shopping.
•Use a refillable travel mug or water bottle.
•Give your time instead of material gifts, or
donate to a charity in the recipient’s name.
Reduce waste
What other ways can you cut down on waste?
31. There’s no place like home…
…and there may never be again. Do your part.
