The document discusses the greenhouse effect and global warming. It explains that the greenhouse effect occurs when certain gases in the atmosphere, such as carbon dioxide, trap heat from the sun and cause the planet to warm. While some level of greenhouse effect is natural, human activities like burning fossil fuels and deforestation have increased greenhouse gas levels and led to additional global warming. The consequences of this warming include more extreme droughts, changes in weather patterns, endangered species, natural disasters, and melting of the poles.
Global warming and climate change are terms for the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.
Multiple lines of scientific evidence show that the climate system is warming.
Temperature changes vary over the globe. Since 1979, land temperatures have increased about twice as fast as ocean temperatures. Ocean temperatures increase more slowly than land temperatures because of the larger effective heat capacity of the oceans and because the ocean loses more heat by evaporation

Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth.
This Presentation is regarding the Global warming, the causes and cure. This was made by Shakeel Ahmed to be presented at Mehran University Institute of Science and Technology Development Jamshoro Sindh Pakistan.
The average global temperature has risen 1.7 degrees F in past 150 years. Average global sea level has increased by 4.7 inches since the last ice age. Sea level rises for two reasons: water expands when it is warmed, and water volume increases as melt water is added. What does it all mean? If the floating Arctic ice caps melt, global sea level will not be affected. If all the snow and ice in Greenland melted, global sea level will rise 24 feet. The “natural” greenhouse effect keeps the earth warm at about 57.9 degrees F, and the “unnatural”greenhouse effect causes the atmosphere’s temperature to rise, followed by a rise in land and ocean temperatures, causing climate change on a global scale. Satellite measurements indicate that the tropo-sphere is warming faster than the earth’s surface. Note: this indicates that greenhouse gases in the atmosphere are absorbing too much heat. Without the “natural” greenhouse effect, Planet Earth would be much colder, for example, a temperature of about minus 2 degrees F. If the “unnatural” greenhouse effect were to get out of control, Planet Earth would be warmer than the current average temperature of 57.9 degrees F. Current scientific debate focuses on what is called the “tipping scenario issue” that “within a few decades, humans will be virtually helpless to slow the perceived risks associated with global climate change… Presentation courtesy of Dr. Walter Hays, Global Alliance For Disaster Reduction

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.

5. WHAT IS THE GREENHOUSE EFFECT?
The Earth’s temperature rises by certain
atmospheric gasses (carbon dioxide,…) that trap
the Sun’s energy. This leads to global warming.
6. WHAT ARE THE CAUSES OF THE GREENHOUSE
EFFECT?
There can be a number of reasons for what causes greenhouse gasses which
then leads to global warming. Most of these pertain to human activity.
DEFORESTATION AND
AGRICULTURE BURNING OF FOSSIL FUELS,
