Earth System True/False HuntOnline version

Test your knowledge on carbon and climate processes.

by Rhiannon
1

Oceans have absorbed only about 5% of human CO2 emissions.

2

The Arctic stores ~1,500 Gt of carbon in frozen soils.

3

The Amazon is approaching a tipping point, with some regions now net carbon sources.

4

The Arctic amplification is slower than the global average.

5

Thawing releases CO2 and methane (CH4).

6

Global average temperature has risen by 10°C since pre-industrial times.

7

Warming is ~4× faster in the Arctic than globally (Arctic amplification).

8

Methane is less potent than CO2 over 50 years.

9

Atmospheric CO2 has risen to ~420+ ppm (2024).

10

Thawing permafrost releases only CO2, not CH4.
