Global Warming

By the end of the 1990s, climate science had grown increasingly precise and achieved virtual worldwide scientific consensus on climate change. The 2001 report of the Intergovernmental Panel on Climate Change concluded that global average surface temperature had increased by 0.6 degrees Celsius during the twentieth century, largely due to greenhouse gas emissions. Carbon dioxide concentrations in the atmosphere had increased by approximately 30 percent since the late nineteenth century, rising from 280 parts per million (ppm) by volume to 367 ppm in 1998.

Theres no doubt that we cant reverse any damage done to nature but All we can do is just lessen the heat build up. But at the status of our attitude I think it would take decades for it to be change or even not at all
