This document discusses climate change and human impacts on the environment. It defines key terms like climate, weather, and greenhouse gases. It explains how the greenhouse effect traps heat in the atmosphere and is impacted by carbon dioxide, methane and water vapor. It also discusses how climate naturally changes over time but that human activities like fossil fuel use, pollution, and ecosystem damage are exacerbating climate change. It provides examples of evidence for climate change through changing ice caps, storms, and plant/animal distributions. Finally, it briefly covers the concepts of biomagnification and invasive species introduction.
Climate like any other physical phenomena it is dynamic and not static.
In every part of the world one year, one decade or one century is different than the other.
The change does not only have academic important but its effects in all the forms of life.
Plants, animals, human beings change with changes of climate.
In general, all living species thrive under definite and limit conditions and any great deviation from that will leads to destruction and death of the species.
Ecology: Scientific study of interactions between organisms and their environments which includes Biotic Factors: (Living organisms) , Abiotic Factors: (Nonliving physical and chemical conditions of an environment).
What are the levels of the Ecology?
Ecology has Five Levels.
Individual organism: Single organism in an environment
Populations: Group of individual organisms of same species living in the same area
Communities: All of the organisms that inhabit a particular area make up a community, like coral reef and other organisms live around in the reef
Ecosystems: An ecosystem includes both the biotic and abiotic factors of an area
Biosphere:
Sum of all of Earth's ecosystems, it is an envelope of air, land, and water supporting all living things on Earth. It consists of both the atmosphere and ocean.
Ecologists investigate global issues in the biosphere, including climate change and its effect on living things
The effects have been most dramatic at high latitudes, where multiple processes contribute to decreased surface reflectivity
Changes in temperature are causing species to shift their natural ranges; however, those are unable to move in line with changing temperatures are being put at risk.
In this presentation, climatic factors like light, temperature and water are explained. Along with this their importance and their effect on plant life is also explained

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
Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
Francesca Gottschalk - How can education support child empowerment.pptxEduSkills OECD
Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. (1) Climate
Climate: Average, annual conditions of temperature
and precipitation in Earth-regions.
Weather = day to day conditions.
Climate is Impacted By:
– Earth’s tilt, rotation, orbit
– Location of Land and Water masses
– Wind and Water Currents
– Concentrations of Greenhouse Gases, Organisms, Inorganic
Compounds

7. (2) Greenhouse Effect
Greenhouse Effect: The containment of
heat on Earth due to shielding gases.
Greenhouse Gases: Gases which absorb
heat, subsequently warming earth’s
atmosphere.
– Carbon Dioxide
– Methane
– Water Vapor

10. (3) Climate Change
Climate Change: A regular, natural change
in the earth’s climates due to a variety of
factors working together.
Cause:
– Any one of the factors which impacts
climate
– Humans are not helping
11.
12. (4) Evidence for Climate Change
Record of the climate changing regularly and
frequently in the past (naturally).
Change in ice caps and water levels.
Change in severity of storms and shifts in
atmospheric temperatures.
Change in survival of climate-specific plants
and animals.
13. (5) Human Activities of Concern
Over-Use of Fossil Fuels & Natural Resources
Over-Production of Waste & Pollution
Damage to Ecosystems
Altering Ecosystem Stability
14. (6) Biomagnification
Also known as “bioamplification”.
Occurs when a chemical compound is released into
an ecosystem, and higher level heterotrophs
receive/contain larger amounts.
EXAMPLE Why Does This Happen?
– A pesticide is absorbed by plankton.
– A small fish eats 100 plankton, each with the pesticide.
– A large fish eats 50 small fish (each with 100 plankton).
– A shark eats 5 large fish (each with 50 small fish).
15.
16. (7) Invasive Species
When non-native species of organisms move into an ecosystem
and disrupt the balance and stability.
Results:
– The non-native organisms might over-use resources.
– The non-native organisms might end up killing off native
organisms.
How Does This Happen?
– Can happen naturally with changes in climate, wind, water
patterns.
– Mostly happens due to humans transporting foreign
organisms into new habitats.
