The Russian Arctic region of Siberia has front row tickets to an approaching climate change rollercoaster ride as it experiences soaring temperatures.

The mercury climbed to 38⁰C (100.4F) in Verkhoyansk, Siberia in June 2020 creating the new record of highest temperature in the arctic region and beating Fort Yukon, Alaska, which recorded 37.8⁰C in June 1915. The forecast for the coming weeks was also a whopping 10⁰C higher than last year. This region is also known for experiencing the coldest temperatures, reaching as low as minus 60⁰C during winters.

Concerned scientists claim that the Arctic is heating with double the speed of global average. “Such heat-waves aren't necessarily new to Siberia, but that climate change is increasing their severity and length,” says Sergei Semyonov of the Yu. A. Izrael Institute of Global Climate and Ecology in Moscow.

The heat waves are occurring due to a ‘heat dome’ effect in the Arctic region. This phenomenon happens when the Air is pushed and compressed, creating a very high mass of air into one location. This heavy air prevents clouds from forming, keeping the weather sunny, and pushes warm temperatures down to the surface which creates a virtual dome in which heat is trapped for a long duration.

This has led to devastating consequences for the environment of the arctic region. The forest areas of Sakha Republic, Russian Federation are witnessing rampant Wildfires. In Siberia, a major diesel oil spill incident happened due to the melting of Permafrost and caused contamination in the Ambarnaya River.

Permafrost serves as a foundation for almost the entire Northern Hemisphere’s landmass and is also responsible for trapping twice the amount of carbon found in the atmosphere. This is a cause of concern, not only for the Arctic, but for the entire globe as it would amount to release of more carbon dioxide in the atmosphere.

Global warming is further fuelling the increase in temperatures of the frigid regions. May 2020 was reportedly the warmest month, according to the climate report of Copernicus Climate Change Service. As a result, snow in these areas melted earlier than it was supposed to. In 2012 as well, around 97% of the ice sheets in Greenland turned to slush due to extensive warming and in 2016, the warm climate in Norway resulted in rainfall instead of snowfall.

From these observations, it would be fitting to state that our planet is undergoing ‘Polar Amplification’, meaning, quicker warming of the poles. Snow cover helps in reflecting the sunlight back in the atmosphere. However, with the gradual warming of Earth, the amount of snow is declining and more heat is being captured instead of being reflected. Melting of snow and icy bodies contributes to sea level rise, increasing the probability of floods in low lying coastal areas.

These events are indicative of the degrading health of our planet which to a large extent are caused by our reckless actions. If we persist with business as usual, the survival of the human race may be as endangered as that of the Siberian tigers.

Sweden’s No Lockdown Policy: How That Changed The Outcome

Sweden has gone against conventional wisdom in its response to the COVID-19 situation. While the neighbouring countries like Denmark, Finland and Norway imposed strict lockdown on the places and services frequented by the public, Sweden has chosen to not do so at all during the initial phases when COVID-19 started taking the shape of a worldwide pandemic. The public places like Cafes, restaurants, gyms, malls, playgrounds, ski slopes and some of the schools were kept open all across Sweden.

The country’s fight against the threat of pandemic was handled exclusively by the Public Health Authority, with no political interference. They believed that a lockdown only serves to delay the virus, which is not necessary since the health services are equipped to deal with the cases. They also made it clear that achieving herd immunity is also not their aim. The public authorities in Sweden instead relied on the public's sense of responsibility, and appealed to them to do frequent hand washing, observe social distancing and keep people over 70 years old from going out.

The state epidemiologist, Anders Tegnell, made multiple statements about the state’s unusual approach, such as 1) “Once you get into a lockdown, it’s difficult to get out of it,”, “How do you reopen?  When?” 2) “There is no evidence whatsoever that doing more at this stage would make

any difference. It’s far better to introduce stringent measures at very specific intervals, and keep them running for as little time as possible” , 3) " As long as the healthcare system reasonably can cope with and give good care to the ones that need care, it's not clear that having the cases later in time is better”.

The assumption of public responsibility did not work for Sweden and there were people out on the streets, in cafes, restaurants and playgrounds. Not wearing a mask was the social norm instead of the reverse. The models for charting the virus spread given by the concerned authorities also turned out to be faulty forcing them to rescind it. Over 2000 Swedish researchers and doctors signed a petition which claimed that there was not enough testing,tracking or isolation in the country. They believed that the authority has clearly not planned their response and that the authority’s claim for herd immunity has very little scientific basis, even though the government has repeatedly claimed that herd immunity is not what they were aiming for.

Sweden’s lax approach to the combating of coronavirus forced its neighbouring Scandinavian countries to close the border for the Swedish citizens. Some of the Swedish officials were worried for the possible harm to the long term relations between Sweden and its neighbours.  Also, the plan of letting life go on as usual to avoid the economic recession occurring due to a lockdown also failed as it didn’t shield  the country from economic slowdown.

Here comes the question; was the lockdown successful or not? There are some comparisons that have been drawn which indicate more deaths per 100,000 people than in nearby countries with homogenous population, even though it is significantly lesser than some of the European countries. While the infections rates are double that of Denmark, the death rates in comparison are much higher. This difference has been attributed to the fact that approximately half of these deaths have occurred in old care homes despite the stated priority of the officials to protect the elderly. This has been in part to the volunteer program, which replaced symptomatic old age home cares with new volunteers, hence increasing exposure. Another factor is the lack of protective equipment in such homes, along with laws preventing administration of medical procedures without the presence of doctors. There were reports of people threatened with lawsuits for banning visitors.

All of this led to Mr.Tegnell claiming that the ideal policy would have been something between what Sweden adopted and what the other countries did, in the light of what they know now. However this claim of Mr.Tegnell will be put to test when the second wave comes, later in time.
