Scientists Confirm Human Role in Climate Change
It’s likely that greenhouse gasses have “contributed substantially to the observed warming over the last fifty years,” says an international panel of climate scientists. They warn that temperatures could rise much more quickly than previously anticipated.
Given the rapid warming that is already taking place in the arctic, this could mean that the melting of major polar features is not far off. The weight and mass of polar ice has declined by 58% over the past fifty years and blue water appeared at the North Pole in July of 2000. Should the pole melt, the resulting flood of relatively warm fresh water into the arctic oceans could cause a decline in the force of ocean currents, and trigger sudden climate change.
