Transcript of Climate Change

Are humans the big causes of climate change ?
What is causing it?
Opinions:
Humans :
Nature :

Climate change can be produce naturaly;
Man-made carbon dioxide emissions throughout human history constitute less than 0.00022 percent of the total naturally emitted from the mantle of the earth during geological history.

HOW IT IS PRODUCED:
So what do we do about it?
CLIMATE CHANGE
Causing changes in Earth’s atmosphere in the amounts of greenhouse gases, from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.

Did you know that climate change also affects in our health?

Burning fossil fuels, weather extremes, rising sea levels, lack of water and poor water quality are some of its examples.

Our health:
OUR OPINION:
In our opinion, we believe that humans have its fault. One of its reasons is because every day we emit a lot of pollution produced by cars, industries, flying and even cooking. Also burning fossil fuels, deforestation and extraction of petroleum affects it really badly, not just us but our world too.
THANK YOU FOR YOUR ATTENTION

Climate change occurs when the factors that influence it changes. Changing climate on a global scale, though, can only occur when the amount of heat in the Earth’s system changes by either being added or released.
The heat entering Earth comes from the Sun. Sunlight enters our atmosphere and heats the land surface and the oceans. The Earth then releases heat back into the atmosphere which radiates into outer space. The amount of heat trapped in the Earth’s atmosphere can fluctuate, possibly due to small changes in Earth’s orbit around the Sun that occur over thousands of years or by changes in the Sun’s intensity. Or, as a result of human actions.
Greenhouse gases allow the lower atmosphere to absorb the heat released by the Earth’s surface, trapping it within our atmosphere preventing it to turn into a block of ice. However the quantity of greenhouse gases in the atmosphere has been rapidly increasing over the past several decades, primarily as the result of burning fossil fuels, which releases carbon dioxide. As a result, the atmosphere is heating at an accelerated pace
