The ice age started in the Poles after the Holocene Climate Optimum
Summary edit
| Description |
English: A new ice age started after the Holocene Climate Optimum, 8,000yrs ago in the Arctic and 10,500 yrs ago in the Antarctic. All polar ice core and global climate reconstructions show that the temperatures today are lower than at the Holocene Climate Optimum. The Arctic temperature fell 4.86 degrees Celsius between 5980BCE and 1700CE, and the Antarctic temperature declined 4.56degrees Celsius between 8577BCE and 1738CE. This fall in temperature happened in a devolving oscillatory manner i.e. sequential warming then cooling phases (i.e., natural climate change). The decline in Arctic temperature since the Holocene Climate Optimum paralleled the Northern Hemisphere's solar irradiance decline of 40-50W/m2 at 65 degrees North latitude (precession of the summer solstice modified).
