1
Q
due to climate change what is more likely due to hotter and drier climates?
A
wildfires
2
Q
what do wildfires release?
A
large quantities of CO2 into atmosphere - increases the warming effect
3
Q
ice reflects what?
A
radiation form the sun
4
Q
what does ice reflecting radiation reduce?
A
surface warming
5
Q
as sea temperatures rise and ice melts, what is amplified?
A
the warming effect
6
Q
why is the warming effect amplified?
A
because there is less ice to reflect the radiation
7
Q
what are higher temperatures thawing?
A
the permaforst
8
Q
what is the permafrost thawing releasing?
A
CO2 and methane
9
Q
how much more does the warming effect than co2 does methane have?
A
20 times
10
Q
what does the thawing of the permafrost cause?
A
warming on a local and global scale
