- Much of Siberia enjoyed an unseasonably warm winter, with heatwaves taking temperatures in some places 10 degrees above average.
- In contrast, there have been snowstorms and tornadoes in June.
- The weather is causing the permafrost layer to melt, leading to a massive oil spill and the spread of wildfires.
One minute it’s T-shirts, the next it’s snow boots. Siberia is experiencing some wild weather swings in 2020.
Russia’s coldest region has just experienced a winter heatwave, with an early start to summer seeing temperatures hit 35°C. Much of Siberia experienced temperatures well above average for the period from June 2019 to May 2020, with some parts 10°C above the average temperatures seen between 1981 and 2010.

But June has brought snow, tornadoes and flooding to the region, with a state of emergency declared in some parts. Villages have been deluged, houses destroyed and bridges washed away.
Oil leaks, wildfires and floods
While locals have been enjoying the sunbathing, early-blooming flowers and harvests, the effects of the temperature fluctuations have had more concerning consequences for the environment.
Back in December, Russian President Vladimir Putin acknowledged the potential severe impact the heatwave could have if it triggered thawing of the permafrost layer on which a number of cities are built.
The melting permafrost led to what environmentalists say is the worst oil spill of its kind in the Russian Arctic. In May, diesel oil started to leak from a storage tank near Norilsk because melting permafrost weakened its supports. Thousands of tonnes of oil have contaminated the nearby Ambarnaya river and surrounding subsoil, and have put other parts of the region at risk.
Meanwhile, ice on a number of rivers has been melting and breaking up earlier than usual, putting some towns on watch for flooding. And there have been extreme wildfires which have been exacerbated by drier conditions.
The global picture
The warmer temperatures in Siberia have contributed to May being the warmest on record globally, 0.63°C warmer than the average May from 1981-2010, according to the Copernicus Climate Change Service from the EU.
There are concerns that the coronavirus pandemic has pushed climate change further down the list of concerns for governments. And although globally greenhouse gas emissions plummeted during the early months of 2020, when many nations were on strict lockdown, they have started to climb again in some places. According to figures from the Centre for Research on Energy and Clean Air, air pollution in China rebounded in May – overshooting concentrations seen during the same period last year.
What is the World Economic Forum doing to champion social innovation?
Social innovators address the world’s most serious challenges ranging from inequality to girls’ education and disaster relief that affect all of us, but in particular vulnerable and excluded groups. To achieve maximum impact and start to address root causes, they need greater visibility, credibility, access to finance, favourable policy decisions, and in some cases a better understanding of global affairs and access to decision makers.
The Schwab Foundation for Social Entrepreneurship is supporting more than 400 late-stage social innovators. By providing an unparalleled global platform, the Foundation’s goal is to highlight and expand proven and impactful models of social innovation. It helps strengthen and grow the field by showcasing best-in-class examples, models for replication and cutting-edge research on social innovation.

In the past, countries have relied on highly polluting industries such as manufacturing and construction to help lift them out of a downturn. But the figures from the CREA underline the need for governments to focus on clean and environmentally friendly economic recoveries as lockdowns ease.
