Earth’s last glacial age was 7,000 years ago. Making human civilization a new modern climate era. Climate changes occur due to the amount of solar energy our planet receives. Scientists working together with NASA believe the earth’s warming trend is due to human-induced greenhouse gases. They use earth-orbiting satellites and other technologies to see pictures and study data. Evidence of a large scale in changes that have happened very quickly, not in hundred or thousands of years , but in only 10 years.

6 Reasons
  • Global sea level grew 17 centimeters (6.7 inches ) in the last 100 years. Shockingly in the last 10 yeas, it has nearly double that of the last 100 years.
  • Since 1880 earth’s global surface temperatures has been warming . Most of it occurred in 1970’s, with the 20 warmest years having occurred in 1981 and with all 10 of the warmest years occurring in the past 12 years. Surface temps continue to rise.
  • Shrinking ice sheets in Greenland show a lost of mass of 150 to 250 kilometers (36 to 60 cubic miles) per year between 2002 and 2006. In Antartica
    it has lost 152 cubic kilometers (36 cubic mile) of ice sheets.
  • Both the extent and thickness of Arctic sea ice has declined rapidly over the over the last decades. Arctic sea ice is now declining at a rate of 13.3 percent per decade, relative to the 1981 to 2010 average.
  • The number of records high temperatures events in the United States have been increasing while the the record low decreasing.
  • Since the industrial revolution the ocean acidification has increased about 30 percent. In order to maintain balanced ecosystem the ocean absorbed an increased amount per year of 2 million tons of human made CO2 emissions.
