Global Protocol- Preliminary Session

Western Europe is just as guilty as the United States when it comes to their contributions to climate change, in particular global warming. The U.S., Western Europe, and Japan (about 15 percent of the world population) are responsible for two- thirds of the world’s carbon dioxide emissions.
Western Europe is a leading burner of fossil fuels, which is a major contributor to the increase of carbon dioxide release into the atmosphere. Other activities such as deforestation also contribute to carbon release; the demand for wood such as mahogany creates the need to cut down large areas of forest, which causes high levels of carbon emissions.
The main issue impacting our region is glacier melt of Greenland contributing to global sea surface rising. The glacier melt that is being added to the ocean is not cold dense water, like the rest of the water in the ocean. This fresh water melt is not being pulled down with enough strength to continue the thermohaline circulation as it should be. The worry is that the "Ocean Conveyor Belt" is slowing down. Sea surface temperatures and levels could, and are rising. Global climate change is more than just warmer temperatures. It's a domino effect melting the glaciers. The chemistry of the ocean is being interfered with. There is a positive feedback as well; water absorbs more solar radiation than it reflects, resulting in more ice heating.
The most common factors that contribute to global warming are cars, trains, refrigerators, and electricity. In Greenland they propose that decreasing the use of greenhouse gas emissions is the first way to start solving global warming and preventing the glaciers in Greenland from melting. Another solution they have is to change the way that they produce and consume energy. Friends of the Earth Europe say that “this can also create millions of new green jobs in sectors such as energy efficiency, energy saving, and renewable energy.” This is a good solution because there is a need for job openings, and this is a good way for people to learn more about the effects of carbon emissions. People will then have a job and also help save the planet. If Western Europe could cut back on the usage of cars, trains and electricity then their usage of carbon dioxide will decrease exponentially. Friends of the Earth Europe say “So far the EU has only agreed to cut greenhouse gas emissions by 20% by 2020, [but] if the European Union takes the lead and shows that Europe is ready to make cuts in greenhouse gas emissions” they could lower their gas emissions by 40% instead of 20% by 2020. Once some takes the lead, other countries will then follow and sooner or later the whole world will then be making an effort to lower their gas emissions to solve global warming.

Short-term weather extremes, not warming, driving Greenland ice sheet flow: Study

http://www.thaindian.com/newsportal/health/short-term-weather-extremes-not-warming-driving-greenland-ice-sheet-flow-study_100471671.html

Another piece of evidence supporting that climate change is more complex than just global warming. "Since the 1990's, it has been documented to be losing approximately 100 billion tonnes of ice per year." And most surprising, it's not only increased temperature that is speeding up the glaciers melting, but the increased rain fall is resulting in increased melt. Gradual warming causes gradual glacial melt, and sudden increases in rainfall can cause glacier melt to spread and speed up. "...during heavy rainfall, higher water pressure is required to force drainage along the base of the ice..." As a result of glacial melt from Greenland, global sea levels rose about 0.14 to 0.28 milimeters per year between 1993 and 2003.

Expectedly Greenland is experiencing warm weather

It has been stated that some parts of Western Europe are witnessing record low temperatures. Greenland, however, known for record lows, has been experiencing higher than usual temperatures. Explanations as to why this is happening include changes in jet stream paths. This change is causing places like Australia to have snow. It seems that warmer air off the Atlantic is being directed towards Greenland and Canada, causing a sort of climate swap.
