Global Warming and Biology

Increasing levels of CO2 and methane are trapping heat in the atmosphere, causing global temperatures to rise.

Give two biological consequences of global warming.

What is Global Warming and Biology?

"Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels."

Question 1

Which gas is a major greenhouse gas linked to global warming?

Question 2

Which gas is a major greenhouse gas linked to global warming?

Question 3

How can deforestation increase atmospheric carbon dioxide levels?

Rising Temperatures

Ice caps melting, leading to rising sea levels and loss of habitat.

Changes in migration patterns and the distribution of pests/disease carriers.

Mass extinction of species that cannot adapt quickly enough.

Exam Tip

Climate change refers to the long-term shift in weather patterns, while global warming is specifically the rise in temperature.
