What is Climate?
Climate - the average variations of weather over a long period of time (~30 years)


Слайд #3
What is Weather?
Weather - all natural phenomena
within the atmosphere at a given
time (hours to days)


Слайд #4
What is Science?
Science is the search for knowledge.
The lunar cycle
The extent of snowfall as the seasons progress from Summer into Winter and then back to Summer again.


Слайд #5
What is Climate Change?
Records change over
decades to millions
of years.


Слайд #6
The Climate System
The Earth has many different systems that interact with each other in different ways.
Oceans
Atmosphere
Ice
Biosphere
Land


Слайд #7
Modern Climate Systems
Atmospheric circulation
Sunlight


Слайд #8
Modern Climate Systems
Ocean circulation
The Great Ocean Conveyor
Sinking cool water, rising warm water and wind help to form global ocean current systems.


Слайд #9
What is the Greenhouse Effect?
The temperature of the Earth depends on the amount of energy we receive from the sun versus the amount of energy lost back out to space.


Слайд #10
Is the Climate Changing?


Слайд #11
What are the current climate trends?


Слайд #12
Future predictions…
Based on
no changes in emissions (“business
as usual”)
The UK would be
2-3.5°C hotter
on average.


Слайд #13
The way to solve the problem.
Recycle
Turn off lights
Low energy light bulbs
Shorter showers
Recycle «grey»water
Install solar panels
Walk or ride instead
of taking a vehicle

and autumn with

of the air.
