Causes Of Climate Change

Question 1

What are the two main types of causes of climate change?

Answer 1

Human causes and natural (physical) causes

Question 2

How does burning fossil fuels cause climate change?

Answer 2

It releases gases like carbon dioxide that trap heat in the air and is the largest contributor to greenhouse gas emissions

Question 3

Deforestation (effects on the climate)

Answer 3

Clearing forests for agricultural and urbanisation reduces the earths capacity to absorb carbon dioxide through photosynthesis
When forests are burned or degraded, carbon dioxide stored in tress in released back into the atmosphere

Question 4

Agriculture (effects on the climate)

Answer 4

Agricultural activities sue as livestock and avocado plantages produce greenhouse gases.
Livestock, specifically cattle, emit methaan during digestion and avocados need a huge amount of water

Question 5

Industrial processes (effects on the climate)

Answer 5

Cement production, chemical manufacturing and waste management release greenhouse gases

Question 6

Explain the term physical causes

Answer 6

Natural things that change the Earth’s climate, but not as fast as humans do and therefore do not account for the rapid and significant warming absorbed in these last decades

Question 7

Explain human causes

Answer 7

Human activities are the primary cause leading to climate change

Question 8

What are Milankovitch cycles?

Answer 8

Slow changes in the Earth’s movement that can change the climate over thousands of years

Question 9

What is El Niño?

Answer 9

Can cause temporary fluctuations in global temperature patterns but does not account for long term warming

Question 10

What is solar irradiance?

Answer 10

Changes in the sun’s energy. But recently, it hasn’t changed much, so it’s not a big cause

Question 11

How do volcanic eruptions affect the climate?

Answer 11

They can release ash and gases that block sunlight and cool the Earth for a short time.
