When did the little ice age begin?
About 20,000 years a go when the earth entered a long period of freezing and cold
No. ice ages are SLOW events, and need a lot more than 7 Days to get going. A typical ice age lasts for thousands of years and takes several centuries to begin or end, as temperatures slowly fall or rise. The "Little Ice Age" happened from about 1300 to about 1850 and it is the shortest documented such event (and did not last long enough to reach the very cold temperatures of typical ice ages).
Strictly speaking the most recent Ice Age started about 2.6 million years ago and we are now in an interglacial period,(warm period), during the Ice Age. The last glacial period started 115,000 years ago and finished about 10,000 years ago, though there were a number of warmer periods during that time.
