Transcript By Rathdown Junior School GLOBAL GLOWERS

By Rathdown Junior School
The Aim and Method
• The aim of our project is to inform people of how serious global
warming is and how to create awareness to try and slow it down.
• We have researched the different categories that make up global
warming. We have had talks from scientists who are in the process of
studying global warming. We have explored the consequences of
global warming and how it may affect the world.
Global Glowers
• Global warming is the current increase in temperature of
the Earth’s surface as well as its atmosphere.
• In the past , when the Earth experienced increases in
temperature, it was the result of natural causes but
today it’s being caused by greenhouse gases such as
carbon dioxide and methane which human activities
produce.
Climate Change
• Climate change is where the average long-term weather patterns of a
region are altered for an extended period of time, typically decades or
longer.
• Climate change is caused by changes in the total amount of energy
that is kept within the Earth’s atmosphere.
Animals and Plants
• Because the earth is getting warmer some species are moving to cooler places
others are finding their natural habitats disappearing altogether.
• Many plants are starting to grow and bloom earlier in the spring and survive
longer into autumn. As the temperature changes, many plants are not capable of
reproducing, causing many plant species to become endangered.
• If the earth keeps getting warmer up to one quarter of all the plants and animals
will become extinct within 100 years.
Rising Sea Levels
• There are two major reasons behinds rising sea levels. First, shrinking
land ice, such as mountain glaciers and polar ice sheets, is releasing
water into the oceans.
• Second, as ocean temperatures rise, the warmer water expands.
Trapped within a basin between the continents, the water has
nowhere to go but up.
Fossil Fuels
• Fossil fuels contain high percentages of carbon and include
petroleum, coal, and natural gas.
• The use of fossil fuels raises serious environmental concerns.
• The burning of fossil fuels produces around 21.3 billion tonnes of
carbon dioxide per year.
Alternative Energy
• There are many other forms of energy that we can use, rather than
using fossil fuels, such as; Solar energy, Hydroelectricity, wind energy
and wave power. All these resources are renewable energy and are
healthy for the environment.
Effects on weather
• Global warming is increasing the intensity of some types of extreme
weather.
• It is changing precipitation and weather patterns in many different
places, making some places dryer, with more intense periods of
drought and at the same time making other places wetter, with
stronger storms and increased flooding.
Is Global Warming a Hoax?
• 3% of the world’s scientists believe that global warming is hoax. U.S.
President Donald Trump has also made claims that global warming is
a hoax. They do not believe that it is caused by human activity. The
average temperature in Ireland has both increased and decreased
over the last 100 years. This supports this view but is strongly rejected
by leading scientists in the field.
Places Around the World
• Ireland: Since 1980, temperatures have increased by about 0.8F◦ every decade, at a
rate much faster than the global average.
• Beijing, China: In Beijing, China, the city is so polluted due to burning a high content
of fossil fuels. Hence, the citizens go around wearing masks, covering their nose and
mouth, to protect them from inhaling the pollution.
• The Alps France/Italy: : The Alps are warming 3 times the global average. The glaciers
there are melting and mountain plants, including alpine flora, are climbing towards
the peeks.
• Kiribati, Pacific Ocean: Last summer Kiribati became the first country to declare that
global warming is making its lands uninhabitable, asking for help in evacuating its
people. This is occurring due to the rising of sea levels.
How to prevent global warming at home
• You can replace your regular lightbulbs with compact fluorescent lightbulbs
• Do not leave appliances on standby
• Replace your single glazed windows with double glazed
• Take a shower instead of a bath
• Plant a tree
• Eat less red meat
• Reuse your shopping bags
• Use less hot water
• Avoid products with lots of packaging
• Use clean fuel
• Choose energy efficient appliances when making new purchases
New inventions
• Many people and countries are finding new ways and
creating new inventions that will help our planet.
• First water powered train: Unveiled by French
manufacturers Alstom this month, the new Coradia iLint
will feature a motor that gains its power from a
hydrogen tank and a fuel cell. Stored in a tank large
enough to fuel a 497-mile journey, the hydrogen’s
chemical energy will be turned into electricity by the
fuel cell, the train will travel up to 87 miles per hour.
• The first motion censored light introduced Los Angelas.
These amazing light are powered by the movement of
people’s feet as they walk down the busy streets. They
use no electricity just renewable energy.
Speakers
Evelyn Cusack
(Meteorologist at Met Éireann)
John Gibbons
(Journalist and Environmentalist)
• Evelyn Cusack came into school to
talk to us about climate change in
the past on the 22nd of December.
The main thing we learned in this
talk was that, though the Earth’s
climate has changed many times in
the past, that has been because of
natural changes, this is the first
time that it is being caused by
humans.
• On Thursday the 1st of December
Mr. John Gibbons came to give us a
talk about Global Warming and
climate change. He showed us
what is happening to our animals,
homes, environment and our
world. He encouraged us to think
of ways that we, as the next
generation can do our part to
reduce global warming.
Kyoto Protocol + Paris agreement
• The Kyoto Protocol is an agreement to the United Nations Convention
on Climate Change, to reduce GHG (greenhouse gas) emissions to an
average of five percent against 1990 levels.
• The Paris Agreement’s aim is to strengthen the global response to the
threat of climate change by keeping a global temperature rise for the
next one-hundred years below 2 degrees.
Conclusion
• Global sea levels are rising at an alarmingly fast rate — 17 centimetres
in the last century alone. The ice sheets continue to decline, and our
oceans are more acidic than ever. We could go on…which is a whole
other problem.
• Take Action before it’s too late!
