Despite rapidly dropping temperatures, there's little sign that the number of refugees making the journey to Europe is lessening. In fact, this week, the International Organization of Migration in Greece announced that it had recorded the highest migration inflows since the beginning of 2015, with about 48,000 migrants crossing into the country between Oct. 17 and Oct. 21.

That's an average of 9,600 a day.

Authorities are unprepared for this surge, IOM says. More than 500,000 people have arrived in Greece since the start of the year, according to figures from the United Nation's refugee agency. While many remain in Greece, overwhelming the country, many others make the  journey north across various countries in hopes of reaching other E.U. states, such as Germany.

The Greek island of Lesbos continues to receive the highest percentage of refugees and migrants, even though it is struggling with the number who have already arrived — more than 270,000. “What we’ve seen this year is something we’ve never seen before," Lt. Cmdr. Antonios Sofiadelis, head of Greek coast guard operations in Lesbos, told The Post's Griff Witte last month.
