Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. This is a type of greenhouse effect.
• Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.
• The rate of warming is increasing. The 20th century's last two decades were the hottest in 400 years and possibly the warmest for several millennia, according to a number of climate studies. And the United Nations' Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the past 12 years are among the dozen warmest since 1850.
• The Arctic is feeling the effects the most. Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004.
Every single day, 70 million tons of Carbon Dioxide are released into our world’s atmosphere. That’s 1.4 billion pounds – yesterday, today, tomorrow, and every single day.
2008 saw the second-lowest summer Arctic sea iceever recorded since satellites began keeping track in 1979, at 1.74 million square miles. This is 860,000 square miles below the average minimum seen in the summers from 1979 to 2000. (Summer 2007 saw the lowest levels ever recorded, at 1.65 million square miles).
