Global warming breaking records in the Arctic say scientists

by Takver - Climate IMC
Saturday Dec 8th, 2012

Records were smashed in the Arctic during 2012 with rapid changes occurring in sea ice extent and surface melt of Greenland Ice sheet according to the latest Arctic Report Card launched at the fall meeting of AGU in San Fransisco this week. These changes happened despite air temperatures being fairly unremarkable. It was the warmest summer in the last 170 years on Greenland.Source: website


"Water Mark" -- The Discovery Files

According to research results from scientists at Rutgers University, future generations will likely witness sea levels rise between 40 and 70 feet higher than at present even if humankind manages to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit).

Global warming

Global warming refers to the rising average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's average surface temperature has increased by about 0.8 C (1.4 F), with about two thirds of the increase occurring since 1980.[2] Warming of the climate system is unequivocal, and scientists are more than 90% certain that most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and the burning of fossil fuels. These findings are recognized by the national science academies of all major industrialized nations.Read more at Wikipedia
