Some may have flown off to Mars in 100,000 years, but what if we had a new glacial period
, much sooner?
could have reached a tipping point during these glacial periods
, triggering a series of chain events that caused temperatures to rise abruptly.
Considering present common occurrence of the genus Sorex in temperate and boreal regions, often crossing the polar circle, these shrews are good candidates to endure glacial period
also in northern refugia (Vega et al.
Likewise, the late Glacial period
, during the early Holocene, (10 500-9000 cal yr BP), herb paramo was the main vegetation type around the study area.
The Holocene is a geological epoch that began after Earth's last glacial period
ended roughly 11,700 years ago and which continues today.
The last glacial period
, which ended 12,000 years ago, began 80,000-70,000 years ago.
Also, at the end of the last glacial period
, the Younger Dryas period was a 1,300 year long return to glacial climates.
Tuliptrees and hickories, for instance, once spanned the temperate zones of North America and Eurasia, but became extinct in Europe when the first glacial period
forced them south against the uninhabitable Alps, Pyrenees and Mediterranean Basin.
Montana has been covered with glaciers several times, and if we are in the beginning of the next glacial period
, I am not afraid that I will have to move.
When it goes back to a glacial period
, lake sediments blow away.
Crossing the narrower and shallower Red Sea would have been possible at the start of the interglacial period; water locked up in ice sheets during the preceding glacial period
was yet to melt and raise the local sea level.
The area also contains endemic species and ecosystem remnants from the last glacial period
2008), a 650-year-long slightly warmer episode of the late glacial period
Despite the fundamental importance of environmental history for diversity and conservation, there is little primary evidence concerning the nature of vegetation in north equatorial Southeast Asia during the Last Glacial Period
Moreover, the decreasing amount of fossil pollen from floating meadows over the last 9,000 years (Absy, 1979) may indicate that few or no floodplains existed during the last glacial period
of lowered sealevel, when the Amazon River flowed in a rather narrow deep "canyon.
