It is not possible to determine whether an individual weather event is linked to climate change, states Michael Tjernström, professor of meteorology at Stockholm University.
Nor in the case of the large amounts of rain that have fallen over Central Europe.
- It is natural that the weather is abnormal - extreme weather situations are part of the natural system and they have always occurred.
It always depends on the weather, it is usually a sequence of events that is completely random, says Michael Tjernström.
May become more common
However, climate change will make floods more common in the future.
- Floods are definitely something that will become more common in the future.
This type of flood is caused by a lot of rain in a short time in combination with this terrain.
But there are also floods due to, for example, tropical hurricanes and rising water levels, says Michael Tjernström.
"A taste"
Berit Arheimer, head of hydrological research at SMHI, is in the same line.
- It is a foretaste of what we may see more of in the future, this type of very extreme weather events linked to summer precipitation.
This is in line with our calculations for future climate, she says.
Giuliano di Baldassarre, professor of hydrology at Uppsala University, emphasizes that climate change will have different effects in different places.
- What we can see is that floods in our part of Europe are more common and more severe.
In other areas, they are becoming rarer, he says.
