In that year, El Nio added to the increased warming caused by the build-up of heat-trapping emissions in the atmosphere, leading to that record-breaking heat. Humans have a direct effect on albedo through emitting industrial aerosols such as sulfates, which accumulate in the atmosphere due to the burning of fossil fuels.

How Is Climate Change Affecting Winter Storms in the US?

The warming ocean is especially important. First, as we warm the ocean, this is creating a bigger temperature contrast with temperatures over the land when Arctic air plunges southward. Another factor is there is more evaporation from the land and ocean as the globe warms, so there is more water vapor in the atmosphere.
