Right, like we can control the climate of the earth like we can the fever of a baby.
If your baby's temperature is 98.7, you probably don't even consider 0.1 degrees a fever. If your baby's temperature is 99.6, you probably give the baby some pediatric Tylonol and see if the baby will sleep off the fever. If your baby continues to have a fever with a temperature of 100 or more, then you go to the doctor.
In global climate temperature terms, if you want to compare it to a baby's body temperature variations, we're talking about the 98.7 to 98.8 range -- not enough above "normal" to warrant any concern.
