New research refutes claims that U.S. forests and vegetation are 'sequestering' enough carbon to offset fossil fuel emissions, suggesting at least 70-90% of emissions stay in atmosphere or be sequestered elsewhere. The study's findings have important implications for the role of the U.S. in combating global warming.
An asteroid impact would cause catastrophic destruction and an impact winter, but a subsequent 'ultraviolet spring' could be even more devastating due to ozone depletion and acid rain. This period of intense UV radiation could lead to widespread DNA damage, mutations, cancer, and plant death.
