SMHI: Double warming in Sweden as well as global

oJosefin Silverberg

The new SMHI figures show that annual average temperatures have increased twice as fast in Sweden as the global average.

Compared to pre-industrial time, the temperature has increased by 1.7 degrees in Sweden.

– For Sweden as a whole, the annual average temperature has risen significantly more than the global average, says Professor Erik Kjellström, Professor of Climate Research, in comment.

From the last 30 years, only two years have been cooler than usual. SMHI has now updated its data with information from 2018 onwards.

– For Sweden as a whole, the annual average temperature has risen significantly more than the global average. Our development is in line with what we can expect from the climate scenarios that exist and calculations of how global warming can affect us, t something that we see happening today, says Erik Kjellström, professor of climatology in SMHI in comment.

Globally, the average temperature rise is 0.73 degrees between 1991 and 2018 compared to 1861–1890, referred to as pre-industrial time.

In Sweden, the average increase is 1.7 degrees for the same period, more than twice as much as the global average.

Global warming has been unevenly distributed across the world and also between different parts of the year. To follow climate change in Sweden, SMHI updates a number of climate indicators each year, based on SMHI measurements around the country, which started in some places in 1860, and so have been happening since over 150 years.

– The temperature increases faster in the Arctic, especially during the winter, and this is also evident in us in Sweden. In northern Sweden, the biggest increase is during the winter. During the summer, progress is weakest, with no systematic difference between the northern and southern parts of the country, said Erik Engström, head of the unit for climate information and statistics at SMHI.

The 2018 forest fire summer was the hottest eighth in Sweden since 1860. Over the last 30 years, only two years, 1996 and 2010, had cooled compared to the average temperature for 1961-1990, the reference period. used for weather and climate comparisons.
