New reports from the National Center for Atmospheric Research tell that sea levels and temperatures will rise over the next century, no matter what we do.
The report expects that by 2001 sea levels will have risen by 25cm on average while temperatures will rise at least 0.5 degrees Celsius.
Researcher Wigley points out that this is one of the more optimistic forecasts - a worst-case scenario would be a 30cm sea level rise and a global temperature increase of 3.5 degrees Celsius.
Researcher Wigley added that global warming is caused by greenhouse gases like carbon dioxide pumped into the atmosphere by human activity. Even if humans stopped pouring greenhouse gases into the atmosphere today, sea levels will rise by 11 centimeters (about 4 inches) over the next century at a minimum, the studies predicted.
