The same as it is in 2O17, the Quaternary glaciation. We are currently in an interglacial period.
"...The Quaternary glaciation, also known as the Pleistocene glaciation or the current ice age, is a series of glacial events separated by interglacial events during the Quaternary period from 2.58 Ma (million years ago) to present. During this period, ice sheets expanded, notably from out of Antarctica and Greenland, and fluctuating ice sheets occurred elsewhere (for example, the Laurentide ice sheet). The major effects of the ice age are erosion and deposition of material over large parts of the continents, modification of river systems, creation of millions of lakes, changes in sea level, development of pluvial lakes far from the ice margins, isostatic adjustment of the crust, and abnormal winds. It affected oceans, flooding, and biological communities. The ice sheets themselves, by raising the albedo, affect a major feedback on climate cooling....
...n popular culture, there is often reference to "the next ice age". Technically, because Earth is already in an ice age at present, this usually refers to the next glacial period (because the Earth is currently in an interglacial period).
In the 1970s a few paleoclimatologists were concerned with the possibility of global cooling, and suggested that the next glacial period could be rapidly approaching. The previous interglacial periods seemed to have lasted about 10,000 years each; a report in 1972 assuming that the present interglacial period would be equally long concluded, "it is likely that the present-day warm epoch will terminate relatively soon if man does not intervene." Since then, our understanding of the climate system has improved. It is known that not all interglacial periods are of the same length and that solar heating varies in a non-linear fashion forced by the Milankovitch orbital cycles (see Causes section above). At the same time, it is also known that greenhouse gases are increasing in concentration with each passing year. Based on the variations in solar heating and on the amount of CO
2 in the atmosphere, some calculations of future temperatures have been made. According to these estimates, the interglacial period Earth is in now may persist for another 50,000 years if CO
2 levels increase to 750 parts per million (ppm) while the recent atmospheric concentration of CO
2 is about 407 ppm by volume. If CO
2 drops instead to 210 ppm, then the next glacial period may only be 15,000 years away. Moreover, studies of seafloor sediments and ice cores from glaciers around the world, namely Greenland, indicate that climatic change is not smooth. Studies of isotopic composition of the ice cores indicate the change from warm to frigid temperatures can occur in a decade or two. In addition, the ice cores show that an ice age is not uniformly cold, nor are interglacial periods uniformly warm (see also stadial). Analysis of ice cores of the entire thickness of the Greenland glacier shows that climate over the last 250,000 years has changed frequently and abruptly. The present interglacial period (the last 10,000 to 15,000 years) has been fairly stable and warm, but the previous one was interrupted by numerous frigid spells lasting hundreds of years. If the previous period was more typical than the present one, the period of stable climate in which humans flourished—inventing agriculture and thus civilization—may have been possible only because of a highly unusual period of stable temperature...."
