Results from a wide-range of climate model simulations suggest that the Earths average surface temperature could be between 1.1 and 5.4°C warmer in 2100 than it was in 2015. Which best summarizes this information:

By 2100, the global average annual temperature will decrease more than 1.1 and
less than 5.4°C.

By 2100, the global average annual temperature will increase more than 5.4°C.

By 2100, the global average annual temperature will decrease more than 1.1°C.

By 2100, the global average annual temperature will increase more than 1.1 and
less than 5.4°C.
