In Finnmark and parts of Troms, good and favorite berry bogs have cracked and disappeared. The reason is warmer and more humid climate. "Almost impossible to reverse," says a bog researcher.

"It is unusual for bears with youngsters to wake up so early and it is difficult to say why these have come out. The bears may have been disturbed by humans or other animals."

Powder on the ground is nearly one meter deep in some parts of Finland's northernmost region.

Dozens of moose carcasses were discovered last spring in a Lapland national park, and Finland animal disease watchdog Evira has since determined that the animals died of malnutrition. The reason why they were unable to find sustenance is a mystery, as the area had relatively normal temperatures and snowfall last winter.

The skiing season ended in Northern Lapland in mid-May, but the weather there is still so cold and snowfall so frequent that the Saariselkä resort will temporarily reopen its slopes, which are currently up to a metre deep in snow.
