Global warming breaking records in the Arctic say scientists

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

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
