Sedimentary rocks are significant carbon reservoirs.
How much CO2 did the 2010 Iceland volcanic eruption emit per day?
150,000 – 300,000 tonnes
This highlights the impact of volcanic activity on atmospheric carbon levels.
What is the largest carbon store in the world?
Oceans
Oceans store 50 times more carbon than the atmosphere.
What percentage of ocean carbon is stored in algae, plants, and coral?
93%
These organisms play a crucial role in the carbon cycle.
What process produces half of the world’s oxygen?
Photosynthesis
This process is vital for sustaining life on Earth.
What percentage of global carbon is stored in soils?

How much carbon do mangroves sequester per hectare every year?
Approximately 1.5 metric tonnes
Mangroves are significant carbon sinks.
What will happen if just 2% of the world’s mangroves are lost?
50 times the natural sequestration rate of carbon will be released
This indicates the importance of mangroves in carbon storage.
By what year will the eastern Alps be completely ice-free?
2100
This points to the impacts of climate change.
How much faster are Arctic regions warming compared to the global average?
Twice as fast
