Answer:
Human activity - Produces greenhouse gasses.
Greenhouse gasses - Cause atmosphere to trap more heat.
Sun's output - Can vary.
Ice age - Peaked 20,000 years ago.
Explanation:
Human activity includes the usage of fossil fuels on a very large scale, and by using them we release huge amounts of greenhouse gasses into the atmosphere.
The greenhouse gasses have the ability to trap the heat that is reflected from the surface of the planet, thus keeping more of it in the atmosphere and causing global temperature rise.
The sun is technically a star, thus an object that produces energy and light, and like every star, it has variations in its activity in accordance with the processes going on on it.
There have been numerous ice ages through the geological past, and the last one of them ended only around 10,000 years ago, with its peak being just 20,000 years ago.

So with the first number in each set, look on the x axis or the horizontal line for the number. For example, 2 1/2 on the horizontal line or x axis is on the right side, next to the two and the x. The second number is on the vertical side, and the same thing. In this case, -1 1/2 would be on the bottom in between the -1 and the arrow.
Now find the place where the two intersect on the coordinate plane, and put a dot there to mark the coordinate.
The maps of world biomes are thought of as maps of theoretical natural vegetation because of heavy interference by humans
The 5 types of biomes includes:
- aquatic
- grassland
- forest
- desert
- tundra
The maps of the combined biomes of world map is seen as theoretical natural vegetation.
In conclusion, the maps of world biomes are thought of as maps of theoretical natural vegetation because of heavy interference by humans
