As Europe's energy costs increase, Russia is burning off large amounts of natural gas.

The gas would have been sent to Germany.

The plant burns an estimated $10 million worth of gas every day.

Scientists are concerned that soot from the burn will impact the ice.

The analysis shows that 4.34 million cubic metres of gas are being burned each day.

There is a new liquified natural gas plant at Portovaya. A large flame on the horizon was the first sign that something wasn't right.

There is a compressor station close to Portovaya which is located at the start of theNordstream 1 line.

The Russian government blamed technical issues for the curtailment of supplies through the line. Germany says the move was a political one.

Researchers have noticed a significant increase in heat coming from the facility they think is burning gas.

Natural gas is being flared. The scale of this burn has confounded experts.

The expert on satellite data from Miami University said that she had never seen an LNG plant flare so much.

We saw a huge peak in June. It has remained very high.

It's more likely that the decision to flare was made for operational reasons.

"Operators are very hesitant to shut down facilities for fear that they may be difficult to restart, and it's probably the case here," he said.

There could be technical challenges in dealing with the large volumes of gas that were being delivered.

The safest way to handle that gas is to flare it off, since it may have had problems handling it.

Europe's trade embargo with Russia could be the reason for it.

Esa Vakkilainen is an energy engineering professor from the LUT University.

They are not able to make high-quality valves because of the trade embargo with Russia. Maybe there are some valves that can't be fixed.

The flaring has not been commented on by the gas company.

Scientists say that each day the flare continues to burn the financial and environmental costs increase.

Russia's dominance in Europe's energy markets can be seen in the volumes, emissions and location of the flare.

Russia can bring energy prices down tomorrow, that's a clear signal. This is gas that could have been exported via alternative routes.

Scientists are concerned about the environmental effects of the burning.

Flare is better than simply releasing the methane which is the key ingredient in the gas and is a very powerful climate warming agent.

According to the World Bank, Russia has the highest amount of flaring in the world.

The burning causes a lot of issues, as well as releasing thousands of tonnes of CO2 equivalent every day.

Black carbon is the name of the sooty particles that are produced through incomplete burning of fuels.

The transport of black carbon northward where it deposits on snow and ice is a particular concern of Prof Matthew Johnson.

Estimates show that flaring is the main source of black carbon deposition in the northern part of the world and any increase in flaring is especially bad.
