SMHI has gathered statistics for the last fifteen years. While meteorologists generally use the thirty year period from 1961-1990 as a standard, SMHI’s Hans Alexandersson is of the opinion that these latest statistics are sufficiently conclusive.
“I think we can now dismiss the argument that we have to wait a while. We can see the changes at a local level in Sweden and we can also see them in global statistics,” Alexandersson told TT.
Statistics for Sweden show that the country has grown warmer and wetter over the last fifteen years. The country is on average a full one degree warmer, mainly as a result of warmer winters.
The average winter temperature on the coast of Norrland has increased by 2.2 degrees. This ties in with global models which suggest more noticeable changes in polar regions.
But SMHI’s statistics also detected major changes in the south of the country during the remaining seasons. Alexandersson was not so sure that this was related to climate change.
“These may be temporary anomalies,” he said.
Rainfall has increased by 40 millimetres per year, with the month of June seeing the most dramatic changes. It is now 36 per cent wetter in June than it was in previous decades.
On the whole SMHI’s statistics seem to bear out the state’s own climate study, which yesterday warned of more rainfall and flooding in Sweden.
