The document discusses the albedo effect and its impact on climate change. It defines albedo as the extent to which an object reflects light from the sun. Changes in albedo, such as melting snow and ice, can impact global temperatures by reducing the amount of sunlight that is reflected. As snow and ice disappear, less sunlight is reflected and more is absorbed, causing further warming of the Earth's surface and contributing to climate change.

Horizontal Distribution & Differences of Temperature
If the Earth was a homogeneous body without the present land/ocean distribution, its temperature distribution would be strictly latitudinal. However, the Earth is more complex than this, being composed of a mosaic of land and water. This mosaic causes latitudinal (horizontal) zonation of temperature to be disrupted spatially.
Energy balance of Earth
The earth-atmosphere energy balance is the balance between incoming energy from the Sun and outgoing energy from the Earth. Energy released from the Sun is emitted as shortwave light and ultraviolet energy. When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth's surface.

E\' stata avviata un’attività di ricerca riguardante l’albedo terrestre e l’influenza di tale proprietà sul cambiamento climatico globale in collaborazione tra CIRIAF, CNR Ambiente e una rete di Imprese per l\'Albedo.
Dalla realizzazione di modelli di validazione e da alcune verifiche sperimentali, sono stati ottenuti dei risultati circa la correlazione fra la radiazione riflessa da superfici trattate con pigmenti o cultivar caratterizzate da spiccata capacità di riflessione della radiazione solare e la quantità di emissioni di Co2eq evitate in atmosfera (circa 10 mq di superficie con riflettenza maggiore del 90% equivale ad una tonnellata di CO2eq).
Il progetto rivoluzionerebbe l\'attività per la mitigazione del riscaldamento globale che fin\'ora pensava solo alla riduzione del CO2. Molto interessati al progetto paesi come la Cina e i paesi del Nord Africa che hanno grandi superfici terrestri da poter trattare per la riduzione dell\'accumulo di calore per effetto della radiazione solare.
Con l’implementazione della seconda fase (lancio di un satellite di probabile fabbricazione italo-cinese e messa in orbita polare eliosincrona), si darebbe avvio alla certificazione di tali superfici ad elevato albedo su scala globale ai fini del riconoscimento di crediti di carbonio validi e commercializzabili all’interno dell’Emission Trading System
E\' infatti possibile la Certificazione da satelite della CO2 compensata mediante superfici ad elevato albedo; tale attività potrà essere articolata nelle seguenti fasi:
- acquisizione di richieste di certificazione di singoli attori interessati al riconoscimento di efficacia delle superfici per il controllo dell’albedo, previa acquisizione di adeguata documentazione progettuale (materiale cartografico/fotografico relativo ai siti di installazione e corrispondente inquadramento meteorologico e geografico);
- valutazione dei progetti e quantificazione della CO2 compensata dall’installazione delle superfici ad elevato albedo;
- rilascio certificati.
TUTTE QUESTE ATTIVITA\' SARANNO SVOLTE DALLE AZIENDE PROMOTRICI PER L\'ALBEDO DA ME COORDINATE IN COLLABORAZIONE DI CIRIAF E CNR.

Heat transfer due to emission of electromagnetic waves is known as thermal radiation. Heat transfer through radiation takes place in form of electromagnetic waves mainly in the infrared region. Radiation emitted by a body is a consequence of thermal agitation of its composing molecules. The underlying mechanisms and the concepts involved are discussed in the ppt
This is likely to be one of the most well-cited pictures oGrazynaBroyles24
This is likely to be one of the most well-cited pictures of Earth called “Blue
Marble”. It was taken on December 7, 1972, by the crew of the Apollo 17
spacecraft. It has a distinct color of blue, because the Earth uniquely carries
an atmosphere and 70% of the Earth’s surface is covered by the ocean.
Atmosphere from Space
We can see our atmosphere even from space. In this figure, the bright layer is
the atmosphere between space and Earth; both are shown here in black.
Please note how thin the atmospheric layer is relative to Earth’s diameter!
Another view
of the
Atmosphere
from Space
This is a zoomed-in image of the atmosphere. You will notice that there is a
gradual color change ranging from a brownish color closer to the Earth’s
surface that transitions to a pale blue and eventually fades into space. The
atmosphere extends about 10,000km into space. There is no exact top to the
atmosphere. Due to the Earth’s gravity, the number of molecules, which
individually each carry mass, gradually decreases outward into space. Most of
the gas molecules are within the lower atmosphere. 90% of the atmosphere’s
mass is in its lower 10km and 99.9997% is within the lower 100km. You will
also notice that there are little blobs in the brownish colored layer close to the
surface. This layer is called the troposphere, the lowest layer of the
atmosphere ranging from 6-10km above sea level. This is where we live,
clouds are formed, daily weather is observed, and the majority of the
molecules exist. The blobs you see are seemingly giant cumulonimbus – dense
towering clouds – often associated with thunderstorms.
Composition of the Atmosphere including
variable components (by volume)
The three elements that make up over 99.9% of the atmosphere – nitrogen,
oxygen, and argon. These elements are abundant in the atmosphere and have
many uses.
Pure nitrogen (N2) is used in its very cold, liquid state as it boils at -195.8 C (or
-320F). Ted Williams, a baseball player who played for the Boston Red Sox for
22 years, and deceased in 2002, is preserved in liquid nitrogen since his family
members chose to have his remains frozen.
Pure oxygen (O2) is used to achieve higher temperatures, to increase the
efficiency of waste incinerators. It is also used as an oxidizing agent, and in
medical applications to assist and sustain a person’s respiratory functions.
Argon (Ar) is a colorless, odorless, nontoxic, and nonreactive gas. It creates
inert environments for growing crystals, often used in semiconductors. It
protects materials against corrosion. It also fills the air space in double-pane
insulating windows.
Earth’s climate system
and interactions of its
components
Two key ideas for this course, especially for the first half is:
1st: Climate is regulated by complex interactions amongst components of
the Earth’s system.
2nd: Understanding climate change can be reduced to understanding

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.
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

A Strategic Approach: GenAI in EducationPeter 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.

15. Introduction What is climate change? In simple terms, climate change is an alteration in long term weather patterns due to human activities. What is Albedo? Albedo is defined as the extent or area to which an object diffusely reflects light from the sun, or it is the ratio of light reflected by a planet or satellite. Albedo levels 2003-2004 Note: Albedo is also measured from 0 to 1 on a scale, 0 for no reflecting power and 1 for perfect reflection.
16. Climate Change The life on earth is made possible by the energy of the sun. With so many data and statistics going around about climate change, it can be confusing and rather complicated. Climate change is cause by many factors such as industrial pollution, car pollution, etc. C02 emissions is one of the largest factor of climate change, coming mainly from the burning of fossil fuel. The sun's ray provide the basic sustenance for life on planet earth. For example this energy helps plant's create food which is the primary source of food for all forms of life.
17.
18.
19. When the snow and ice disappears, less sun rays are reflected out and instead the heat is absorbed by land and sea - which causes further increase in the warming.
20. Change to the Earth's Albedo is a powerful driver of climate. When the planet's Albedo or reflectivity increases, more incoming sunlight is reflected back into space.
21.
22. Terrestrial Albedo Effects Trees: Because trees tend to have a low Albedo, removing forests would tend to increase Albedo and thereby could produce localized climate cooling. In seasonally snow-covered zones, winter Albedo of treeless areas are 10% to 50% higher than nearby forested areas because snow does not cover the trees as readily . Snow: Snow Albedo can be as high as 0.9; this, however, is for the ideal example: fresh deep snow over a featureless landscape. If a snow-covered area warms, snow tends to melt, lowering the Albedo, and leading to more snowmelt. Water: Water reflects light very differently from typical terrestrial materials. At the scale of the wavelength of light even wavy water is always smooth so the light is reflected in a locally specular manner. Although the reflectivity of water is very low at low and medium angles of incident light, it increases tremendously at high angles of incident light such as occur on the illuminated side of the Earth near the terminator. However, waviness causes an appreciable reduction. Since the light specularly reflected from water does not usually reach the viewer, water is usually considered to have a very low Albedo in spite of its high reflectivity at high angles of incident light. Clouds: Cloud Albedo is an important factor in the global warming effect. Different types of clouds exhibit different reflectivity. Albedo and climate in some areas are affected by artificial clouds, such as those created by the contrails of heavy commercial airliner. Cited from: http://en.wikipedia.org/wiki/Albedo
23.
24. This melts the ice and increases the global temperature to a few degrees, when ice melts, it can cause flooding in some areas.
25. Exposed water or exposed land is darker in colour and it absorbs more energy from the sun. When the ice melts, more land is exposed, this absorbs more heat, melting more ice.
26. The snow and ice play a important role. without them the sunlight will not reflect back and temperature will rise causing global warming due to an imbalance of light being reflected and absorbed.Anything white for example snow or ice have a high Albedo level
29. In order for the earth to have a stable temperature, there has to be a balance between the light being reflected and absorbed.
30. With increasing C02 in our atmosphere more and more heat from the sun's rays are being trapped and due to this we are having an increase in temperature in some countries which is causing the weather patterns to be changed.
31. As we are losing more arctic ice shields we are exposing more soil and earth land which has far less albedo then ice covered land.
