Global Warming atau Efek Pemanasan Global merupakan suatu gejala alam yang dapat menimbulkan bencana pada alam,akibat adanya efek rumah kaca, yaitu suatu efek penerapan panas yang mana sebagian panas yang diserap oleh bagian selimut atmosfir yang tidak dikeluarkan lagi atau tetap berada pada selimut atmosfir dan dapat memanaskan suhu bumi secara berangsur-angsur yang dapat menimbulkan mencairnya es di kutub, sehingga sebagian pulau atau daratan dapat terendam air pada suatu saat.
Global warming is the theory that we as humans are
increasing greenhouse gases through industrialization causing more gases and the increasing the amount of sunlight that gets caught and heats the earth.

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. Presentation by Rahul Singh, Ashish Sharma. Project Guide: Dr. Tanuja NAutiyal
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.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

3. Introduction
• Is the world getting warmer?
• If so, are the actions of mankind to
blame for earth’s temperature
increases?
• What can/should be done about these
issues?
4. History of Earth’s Climate
• Earth formed ~4.6 billion years ago
• Originally very hot
• Sun’s energy output only 70% of
present
• Liquid water present ~4.3 billion
years
5. History of Earth’s Climate
• Life appeared ~3.8 billion years ago
• Photosynthesis began 3.5-2.5 billion years
ago
– Produced oxygen and removed carbon
dioxide and methane (greenhouse gases)
– Earth went through periods of cooling
(“Snowball Earth”) and warming
• Earth began cycles of glacial and
interglacial periods ~3 million years ago
13. The U.S. emits about 6.4 billion metric
tons of greenhouse gases annually, 25%
of the world’s total.
6.4 billion metric tons
CO2/yr
These greenhouse gases last a
long time…
Carbon dioxide stays in the
atmosphere for approximately
100 years, methane lasts about
12 years. Other greenhouse
gases last even longer.
Warming begets more warming…
As these gases continue to raise surface
temperatures, they trigger the release of even
greater quantities of carbon dioxide and methane
that are currently trapped in frozen Arctic
permafrost and tundra soils, further increasing
temperatures.
A feedback mechanism ensues…
…potentially causing “runaway global warming”.

16. Future Carbon Dioxide
Levels
• Increasing CO2 emissions, especially
in China and developing countries
• Likely to double within 150 years:
– Increased coal usage
– Increased natural gas usage
– Decreased petroleum usage (increased
cost and decreasing supply)
17. Households are Big Contributors to Climate Change
Of all U.S. greenhouse gas
emissions come from
households:
• Vehicles
• Home Heating
• Electricity
18. So how can each of us slow
global warming now?
19. Reduce our consumption of fossil fuels
Because greenhouse gas emissions are tied very closely to our
energy consumption, using less fossil fuel based energy puts fewer
greenhouse gases into the atmosphere.
This will help slow global warming.

24. We can make some simple substitutions
Replacing just 1 incandescent light bulb with 1 compact
florescent bulb saves about 150 pounds of carbon
dioxide per year!
If every American household replaced just 5 high-use
incandescent bulbs with compact florescent lights we'd
collectively save more than $8 billion each year in energy costs
and we would prevent the greenhouse gases equivalent to the
emissions from nearly 10 million cars.

Replace your old refrigerator
with a new Energy Star:
Annual savings:
$90; 700 pounds CO2
Set your thermostat down a few
degrees in the winter
Annual savings:
$135; 1400 pounds CO2
Drive JUST 10 fewer miles per week
Annual savings:
$80; 520 pounds CO2
Wash clothes in cold water only
Annual savings:
$70; 500 pounds CO2
Caulk and weather-strip around doors
and windows
Annual savings:
$80; 650 pounds CO2
Reduce your garbage by 10%
through greater recycling or reduced
packaging
Annual savings:
1200 pounds CO2
These are mid-range estimates from
published sources; your savings may vary.

26. Blowing Up Your World
• 1. How many of you leave your
bedroom light on when you are
not in the room?
• Turning off lights saves energy and
money. The more energy used, the
more rivers are dammed or more fossil
fuel is burned, causing air pollution
and increased levels of carbon dioxide
in the atmosphere. 2 pts d
27. Blowing Up Your World
• How many of you walked, bicycled or
took public transportation to get to
school today, instead of coming by
private automobile?
Our reliance on cars that burn fossil fuels
is one of the major causes of increased
levels of carbon dioxide in the atmosphere
and it is the primary cause of urban smog.

• How many of you, when you drink a
soft drink, throw the container into the
garbage?
• Throwing away containers of any kind wastes
energy and resources and adds to our waste
problem. Many towns are running out of landfill
space. 3 pts d

How many of you eat fresh vegetables
instead of canned or frozen?
Fresh vegetables cook more quickly and are
usually more nutritious than frozen or canned
foods. Canned and frozen vegetables are often
over-processed, contain additives, contribute to
air pollution (transport and packaging) and add
to our waste problem. 4 pts u
30. Blowing Up Your World
• How many of you use a hairdryer or
other energy-consuming convenience
appliance, especially in the morning?
• Hairdryers use a lot of energy. In the
morning so much energy demand is put
on our grids that power companies have
to find other sources of energy just to
meet the morning rush hour 2 pts d
31. Blowing Up Your World
• . How many of you, when you go to a store,
get a bag for your purchases, even if you
have only one or two small items to carry?
• Making paper and plastic bags uses energy
and resources. The bags add to our litter
and waste problems, and plastic is not
biodegradable. Recycling is not the best
answer because collecting and recycling
materials requires energy. Instead, carry a
reusable cloth bag or a knapsack with you.

This is a big picture examination of the earth’s climate
The Earth was formed around 4.6 billion years ago
And was originally very hot
However, the Sun’s energy output was only 70% of what it is presently
Liquid water was present on the surface around 4.3 billion years ago
In examining global warming, we will be looking at questions such as
Is the world getting warmer?
If so, are the actions of mankind to blame for earth’s temperature increases?
What can or should be done about global warming?
Are the potential resolutions to global warming worth the cost to implement them?

The first life forms appeared ~3.8 billion years ago
Photosynthesis began 3.5-2.5 billion years ago,
which produced oxygen and removed carbon dioxide and methane, which are greenhouse gases, from the atmosphere
As a result, the Earth went through periods of cooling, commonly referred to as “Snowball Earth” and subsequent warming
Earth began its current cycles of glacial and interglacial periods around 3 million years ago
The temperature of the earth is directly related to the energy input from the Sun. Some of the Sun’s energy is reflected by clouds. Other is reflected by ice. The remainder is absorbed by the earth.
If amount of solar energy absorbed by the earth is equal to the amount radiated back into space, the earth remains at a constant temperature.
However, if the amount of solar energy is greater than the amount radiated, then the earth heats up.
If the amount of solar energy is less than the amount radiated, then the earth cools down.
To a certain degree, the earth acts like a greenhouse. Energy from the Sun penetrates the glass of a greenhouse and warms the air and objects within the greenhouse. The same glass slows the heat from escaping, resulting in much higher temperatures within the greenhouse than outside it.
Likewise, the earth’s atmospheric gases affect the ability of the earth to radiate the Sun’s energy back into space. Nitrogen and Oxygen make up 99% of the earth’s atmospheric gases and are non-greenhouse gases. Water, Carbon Dioxide, and Methane make up 1% of the earth’s atmosphere, but are greenhouse gases, since they cause the earth to retain heat.
This spike is due to the exponential increase in the use of fossil fuels over the last 150 years. Shown here are emissions of carbon from gas, solid, liquid fuels, and the total carbon emissions.
Despite this rapid increase in carbon emissions, only about half the carbon can be detected in the atmosphere. The remainder of the carbon dioxide is being dissolved in the oceans or incorporated into trees.
Future Carbon Emissions
will probably increase, especially in China and developing countries
This will result in a likely doubling of carbon dioxide levels within 150 years, due to
Increased coal usage
And increased natural gas usage,
although petroleum usage is likely to decrease due to increased cost and decreasing supply
