_____ is the astronomical motion considered by Milankovitch as most related to the seasons.
Global warming refers to present-day warming of the world's climate that most scientists believe is likely to continue and is, at least, partly caused by human activities.
The term albedo refers to the reflectivity of a surface as a percentage of the total reflected radiation.
Scientists commonly use variations of the Köppen system to describe the present-day distribution of climate zones.
Milankovitch cycles are the combined influences of astronomical-orbital factors that produce changes in Earth's climate.
Fossils of tiny sea creatures called foraminifera, which once lived in surface waters, equilibrate with the water around them, preserving a chemical record of past climatic changes
