Presentation Global Climate Change Prepared by Oleksandra Pekhno

Presentation: «Global Climate Change» Prepared by Oleksandra Pekhn’o Form 11 -A School of Chynadiievo

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

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

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.

What is Climate Change? • Records change over • decades to millions • of years.

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

Modern Climate Systems • Atmospheric circulation Sunlight

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

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.

Is the Climate Changing?

What are the current climate trends?

Future predictions… Based on no changes in emissions (“business as usual”) The UK would be 2 -3. 5°C hotter on average.

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

Four Seasons Winter Autumn Spring Summer

Winter • Winter - one of the four seasons between autumn and spring climatic season with the lowest temperatures for the area in the air.

Spring • Spring - one of the four seasons between winter and summer, where temperatures are bitter winter air from moving to warmer.

Summer • Summer - one of the four seasons between spring and autumn with the highest average temperature of the air.

Autumn • Autumn - one of the four seasons between summer and winter. Autumn - the transition season when daylight hours decrease markedly and progressively reduced the average daily air temperature.
