" in the Flow, the lower the säve river is a solid class 2, while the flow rate of the summers are warm to the upper parts start to fall off the hook. The trend in the forecast is that the flow rate will continue to decline. Now, it is a relatively dry and cold for a few days, and there is an explanation for the fact that the precipitation in the Tuesday, has not had a greater impact on water resources, " says Niclas Hjerdt.

He explains that there is a natural variation in temperature from year to year. However, you will see a trend toward warmer winters, in general.

" Even if it's jumping up and down from year to year, so that we can see that there is a clear trend. The more frequent warm winters. It was a very, very rare for a number of years ago, is becoming more and more common. The coldest temperatures will come, not now, " says Niclas Hjerdt.
