Climate Change Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What is climate change?

Climate change refers to long-term variations in the Earth’s climate system, including changes in temperature, precipitation, wind patterns, and other weather conditions. It is a natural process but has been significantly accelerated by human activities in recent times.

What indicators show climate change from the Quaternary period to the present day?

Indicators include the early onset of spring, shrinking glaciers, ice cores revealing atmospheric gas concentrations, rising sea levels, and increasing global temperatures based on thermometer readings.

How do melting and retreating glaciers indicate climate change?

Glaciers worldwide have been melting and retreating due to increased global temperatures. This contributes to rising sea levels and the loss of ice in the Arctic, worsening the impacts of climate change.

What information do ice cores provide about climate change?

Ice cores contain trapped air bubbles that reveal atmospheric gas concentrations from when the ice formed. They show that Earth’s temperature has rapidly increased in recent decades, indicating that humans have caused climate change.

How have global sea levels changed since 1900, and what are the impacts?

Global sea levels have risen by approximately 0.21 metres since 1900, mainly due to melting glaciers and ice sheets, and the expansion of seawater from higher temperatures. This causes increased flooding, erosion, and loss of coastal habitats.

What do thermometer readings tell us about recent climate trends?

Thermometer readings show that Earth’s average surface air temperature has risen by about 1°C since 1900. The decade from 2010 to 2020 was the warmest recorded, with 2016 and 2020 being the hottest years.

Future warming depends on greenhouse gas emissions and natural changes in climate.
