Climate Change

The climate change is a

sudden or gradual change in

Earth’s climate, and it longs

periods of time until new

equilibrium is reached.

Green-House Effect

Earth's climate history

Earth has an amazing

variety of climates, like

dry, cold polar regions to

the wet, hot tropics etc.

Scientists study climates

to better understand how

the atmosphere, water,

land masses, and solar

energy interact within a

climate.

Is the process by wich the gases trap heat, keeping Earth warm.

Without green-house gases thermal energy would radiate from Earth's surface and scape directly into space, and it would make our planet to coold to support life

By studying the data from yearly climate patterns in

an area, scientists can observe that some years are

cooler and wetter, while others are hotter and drier.

Scientists collect ice cores by drilling down through

layers of ice, sometimes kilometers thick.

The ice

cores, wich look like glass rods, contain air bubbles

and particles such as sea, salt, and dust, and by

analyzing some of these materials they know how

climate has changed.

Types of climate change

-Tropical

-Dry

-Temperate

-Continental

-Polar

Human activities

We change Earth's surface by releasing green-house gases such as carbon dioxide or methane.
