Document Summary
Gaining a historic perspective on climate change (cont. ) The first discoveries that helped explain recent climate change and global warming began during the 18th and 19th century. 1827 jean baptiste fourier suggested that an atmospheric effect kept the earth warmer than what would otherwise be - he used the analogy of the greenhouse. 1753 john tyndall discovered some gases block infrared radiation. He suggests that the concentration of the gases could bring climate change. 1896 arrhenius proposed that co2 emissions from the burning coal would enhance the earth"s greenhouse effect and lead to global warming, first to point to anthropogenic climate change. First one to say we have an affect! Callendar argues that co2 greenhouse global warming is underway, reviving interest in the issue. From the late 1950s co2 measurements were made on a mountain top in hawaii. Over the next decade these measurements confirmed that levels of co2 in the atmosphere were rising year on year.
