In the last 11 years since 2000, 9 of them have been the warmest years ever recorded. NASA’s Goddard Institute for Space Studies has kept temperature records since 1880, and the records show that the first 11 years of the 2000′s were hotter than both the middle and late 20th century, according to James Hansen, the institute’s director. The study links the hotter temperatures with our CO2 emissions and greenhouse gasses:
The NASA statement said the current higher temperatures are largely sustained by increased concentrations of greenhouse gases in the atmosphere, especially carbon dioxide. Carbon dioxide is emitted by various human activities, from coal-fired power plants to fossil-fueled vehicles to human breath.
Current levels of CO2 are way above the 350 parts per million level, at 390ppm. Scientists and climate experts have determined that 350ppm is the safest upper limit for CO2 in our atmosphere, but we are well above it and continuing to climb. With record temperatures in the last 11 years and climate disasters getting more drastic and expensive each year, the future is not looking too bright anymore.
