� Air pollution has dropped significantly in China and globally
� The waters of Venice are clean once again
� New York's air has also gotten cleaner
� Air pollution is dropping as planes are getting grounded
� Emissions from coal combustion are falling in China
� Domestic energy use rising, commercial use is falling further reducing emissions
So, which are these (temporary) «benefits» for the environment?

We can now meet our Paris Climate Accord goals
sooner
Human-generated emissions cause global warming.
Carbon dioxide, nitrous oxide, and methane are gases
that collect in the atmosphere and prevent heat from
radiating from earth’s surface into space, creating
what’s known as the greenhouse effect.
The 32-page document establishes a framework for
global climate action, including the mitigation of and
adaptation to climate change, support for developing
nations, and the transparent reporting and strengthening
of climate goals.

THE
GREENHOUSE
EFFECT
Heat from the sun shines onto the
Earth.
It passes through a
blanket of gases in our
atmosphere.
ENERGY ENGINEERING_Lecture 6 08/04/2020
Prof.ssa Elena INTORCIA 6
Some of the heat energy is
reflected back into space.
Some of the heat energy is
absorbed by the blanket
of gases.
The ‘greenhouse’ gases (methane, nitrous
oxide, water vapour and carbon dioxide) are
essential to life on Earth. Without them heat
energy would escape back into space.
Earth would be a very chilly
place with an average
temperature of -18°C !
ENERGY ENGINEERING_Lecture 6 08/04/2020
Prof.ssa Elena INTORCIA 7
The gases work a bit like
glass in a greenhouse to
trap in warmth.
But the earth is getting
warmer and warmer.
WHY?
The greenhouse gases help to keep the
temperature of the earth in balance. This
process is called the Greenhouse Effect.
Human activities are creating more
greenhouse gases including carbon
dioxide, CO2.
As we burn more fossil
fuels, for example, the
blanket of greenhouse
gases becomes thicker.
ENERGY ENGINEERING_Lecture 6 08/04/2020
Prof.ssa Elena INTORCIA 8
More greenhouse gases in the atmosphere
mean that more heat energy is absorbed.
We call this increase in the temperature of
the earth ‘global warming’.
Eleven of the last twelve
years have been the hottest
since records started in 1858.
Think about ways that you
could reduce your carbon
footprint and be part of the
climate-change solution!
Incoming radiation from the sun takes form of ultraviolet and visible radiation.
Some of this radiation is absorbed by the Earth’s atmosphere and some of the radiation is reflected back into space by the Earth’s surface (ground).
The radiation which is reflected back into spacetakes form of infrared radiation.
The greenhouse gases present in the atmosphere absorb infrared radiation and reflect it back towards the Earth’s surface.
The greenhouse effect, from Green Issues, p.10
ENERGY ENGINEERING_Lecture 6 08/04/2020
Prof.ssa Elena INTORCIA 9
Thus, heat energy becomes trapped inside earth’s atmosphere and accumulates, leading to the greenhouse effect and an increase in average mean temperatures on earth.
Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface. Normally, this radiation would escape into space—but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter. That's what's known as the greenhouse effect.
ENERGY ENGINEERING_Lecture 6 08/04/2020
Prof.ssa Elena INTORCIA 10
Global warming reduces ice/snow cover. This causes a decrease in albedo and increases the rate of heat absorption by the Earth.
CHAIN REACTION:
/alˈbiːdəʊ/
fraction of light that is
reflected by a body or
surface
ENERGY ENGINEERING_Lecture 6 08/04/2020
Prof.ssa Elena INTORCIA 11
Effects:
� Rise in mean sea level by the melting of ice on land.
� Extreme weather such as heat waves and heavy floods.
The solubility of carbon dioxide in the sea decreases with increasing temperature, leading to an increase in atmosphere carbon dioxide (greenhouse gas) concentration.
WRITING
PRACTICE
Write a short
definition of
climate change,
then report one or
more recent
episodes related
to it.

ALTERNATIVE LIVING
Watch this short video and take notes about each of
its three sections.
Green Issues, p.11 (www.ing.unisannio.it/intorcia)
ALTERNATIVE ENERGY� One of the biggest challenges we face today: …
� What do we need energy for?
� Which problems are caused by traditional energy sources?
� Why is the development of alternative energy sources becoming important?
� Which forms of energy do we need?
� What kind of energy will we be using in the future?
� Which green energy is used in Iceland?
� What are they building in the UAE?
� Describe the main features of this place.

In the USA there are private and public
schools.
Children aged three, four, and five attend
the Kindergarten; at the age of 6 they start
Primary education, followed by
secondary education and university.
There are three main systems, according to the place where you live, or the school you choose to attend:
Grade Age
ENERGY ENGINEERING_Lecture 6 08/04/2020
Prof.ssa Elena INTORCIA 17
� the system called 6 plus 3 plus 3: there are six years of primary education, 3 years of junior and 3 years of senior high schools;
Grade Age
� the system called 6 plus 6: there are six years of primary education and six years of combined Junior and Senior high school;
Grade Age
ENERGY ENGINEERING_Lecture 6 08/04/2020
Prof.ssa Elena INTORCIA 18
� the system called 8 plus 4, with 8 years of combined primary and junior high school and 4 years of secondary high school.
Grade Age
GRADES (voti)
Students are graded with letters:
� A � excellent
� B � good
� C � average
� D � poor
� E � very poor
� F � failure
ENERGY ENGINEERING_Lecture 6 08/04/2020
Prof.ssa Elena INTORCIA 19
The total number of grades (anni scolastici) is 12
and not all the schools offer the 12 grades.
During their last year of high school students sit
the S.A.T. (Scholastic assessment test) if they want
to attend a college or university.
There are private and state colleges and
universities.
Foreign languages, which used to be taught at
high schools only, are now being introduced during
the last few years of elementary school in some
areas (although in some cities, state schools don’t
offer any foreign language teaching).
The most popular foreign languages:
American Sign Language � deaf people
ENERGY ENGINEERING_Lecture 6 08/04/2020
Prof.ssa Elena INTORCIA 20
Elementary students are usually given homework; however, the workload (carico di lavoro) is lighter than in many countries. The workload increases with higher grades.
Secondary school students must take certain ‘core’
curriculum courses for a prescribed number of years or
terms, as determined by each state.
These generally include english, mathematics, general
science, health, physical education and social studies or
social sciences (which may include american history and
government, geography, world history and social
problems).
In addition to mandatory subjects students choose ‘electives’ (optional subjects), which supplement their future education and career plans. Electives usually comprise around half of a student’s work in grades 9 to 12. Students concentrate on four subjects each quarterand are seldom pushed beyond their capability or capacity for learning.

The nation’s most sweeping education law — the elementary and secondary education act of 1965, better known as no child left behind.
ENERGY ENGINEERING_Lecture 6 08/04/2020
Prof.ssa Elena INTORCIA 22
STILL SEPARATE AND UNEQUAL
� America spends a lot of money per student
� The U.S. ranks fifth in spending per student
� Socio-economic class plays a larger role in the U.S. than in other countries
� A different starting line – educational expectations are lower for black children
� Separate and Unequal – More than 2 million black students attend schools where 90 % of students are from minority students.
The No Child Left Behind Act of 2001 (No Child Left Behind) is a landmark in education reform designed to improve student achievement and change the culture of America’s schools.
With passage of No Child Left Behind, Congress emphasized federal efforts to support elementary and secondary education in the United States.
ENERGY ENGINEERING_Lecture 6 08/04/2020
Prof.ssa Elena INTORCIA 23
S.A.T. � Test for college admissions- introduced in 1901- includes three 800-point sections (maths, critical reading, and writing)- possible scores from 600 to 2,400
Since education standards and requirements differ
from state to state, most colleges require students to
take standardized tests, namely ACT, SAT, TOEFEL.
There is no national diploma � the value of a
degree depends on the prestige of the university.
