According to the Environment Canada, the country’s major environmental agency, Canada will fail to reduce greenhouse gas emissions and achieve its 2020 targets because of emissions from tar sands.
The rapid development of tar sands in Canada which injects steam into thick oil deposits to produce oil will account for 62 million metric tons of CO2 emissions from 2005 to 2020, almost dwarfing 31 million metric tons in planned CO2 reductions as Canada’s power plants switch from burning coal to natural gas.
The recent study by Canada’s Pembina Institute estimates that by 2020 Alberta’s tar sands will account for 12 percent of Canada’s total CO2 emissions.
Tar sands will be the main reason why Canada will likely exceed its 2020 CO2 emissions reductions target by gigantic 178 million metric tons.
The Canadian fossil fuel industry, as expected, has denied these reports claiming they are far blown out of proportion because new technologies being employed in tar sands will help significantly reduce emissions in the upcoming years.
One thing is sure though, Canada has a very difficult task in reducing the amount of greenhouse gas emissions in years to come.
Russia's permafrost melting could further increase global climate change impact as according to the latest scientific estimates Russia could lose 15-30 percent of its permafrost by the year 2050.
Permafrost refers to the soil that has been permanently frozen and it currently covers around 63% of Russia's territory. Once permafrost melts it will release massive amounts of greenhouse gas methane currently stored in the frozen soil which will add more impact to climate change.
Not only that, thawing of permafrost will also give huge problems to transportation, building, and energy extraction infrastructure, accounting also for huge economic damage.
The temperatures in western Siberia territories will rise by up to two degrees Celsius to just three or four degrees below zero which will result in shifting of the boundary of the permafrost to the north-east by 150-200 kilometres.
This negative news have come from the Andrei Bolov, the head of the ministry's disaster monitoring department. He also added that "the negative impact of permafrost degradation on all above-ground transportation infrastructure is clear.
The ideal solution to solve the climate change issue would be turning carbon dioxide (CO2) into something useful such as fuel and plastics but the current scientific reports claim that this solution is years off, mostly because of very high construction costs.
Some pilot projects showed great promise such as manufacture of concrete, plastics and oils from carbon dioxide but the main drawbacks of all these pilot projects were high construction and operational costs.
Carbon capture and storage solutions that aim to store and bury carbon dioxide underground are also connected with relatively high costs but are currently receiving more attention than technologies that aim to transform CO2 into some useful products. However, these technologies have so far been used only in some regional pilot projects, still lacking global character.
This means that at this moment the only possible solution to tackle climate change is to significantly reduce global level of greenhouse gas emissions and this sadly cannot be achieved without the international climate deal.
International climate deal also looks to be years off because there is still a huge difference in opinion between developed and the developing world. The world leaders continue with their talks and promises but there's nothing concrete coming out of it. Hope for new climate deal seems to be fading away with each new disappointing talk.
At this moment there doesn't seem to be some easy solution to tackle climate change. There's no magic trick that will return climate back to the normal, the only solution at this time is to make a drastic cut in greenhouse gas emissions.
