Hello student, in this question we're asked to list down the differences between climate change and biome shift of the past and present.
00:10
So let us look at the present climate change and biome.
00:26
So ever since the industrial revolution what happened is that the use of fossil fuels has increased.
00:44
There has been a demand for more land for cultivation.
00:56
This means that there needs to be deforestation.
01:03
There is demand for land for settlement, urbanization, development etc.
01:16
This also leads to deforestation.
01:19
Coming up of technology, increased use of vehicles, all this leads to a contribution of exhaust release.
01:44
As a result, what happens is that the greenhouse gases increases and when this increase then this leads to the increase of greenhouse effect.
01:58
Increase in greenhouse effect increases the global temperature.
02:09
So as a result, what happens it leads to melting of glaciers.
02:17
It leads to a shift in the rainfall pattern.
02:28
In some areas there is less rainfall and it leads to drought.
02:35
All of these effects can be seen in the ecosystem.
02:44
How this affects the ecosystem is that there is a biome shift...
