Increasing ozone near the Earth's surface could lead to significant reductions in regional plant production and crop yields. Surface ozone also damages plants, affecting their ability to soak up carbon dioxide from the atmosphere and accelerating global warming. Near-surface ozone has doubled since 1850 due to chemical emissions from vehicles, industrial processes, and the burning of forests.

If heat-trapping emissions are not significantly curtailed, global warming will substantially change critical aspects of the Northeast's character and economy ... Winters will be on average 8 to 12 degrees warmer by the end of the century, and summers 6 to 14 degrees hotter ... the environment of the Northeast would be transformed, and Boston, Atlantic City, New York and other cities would all be subject to disastrous flooding on a regular basis.

Cyclical changes in the sun's energy output are not responsible for Earth's recent global warming ... Instead the findings put the blame for climate change squarely on human-created carbon dioxide (CO2) and other greenhouse gases—reinforcing the beliefs of most climate scientists.
