The latest scientific research indicates that there could be no ice at the North Pole this summer, while the Siberian permafrost—soil that is below freezing temperatures year round—may start melting three times faster.
The scientific consensus on global warming is that it has been caused by
greenhouse gases such as carbon dioxide, which are emitted by fossil fuel-based
power plants, automobiles and other sources.
The melting now extends 1,000 miles inland into areas that previously have been
frozen all year long. As the area of sea ice decreases, less sunlight is
reflected and more heat is absorbed.
It is not the case that temperatures are simply going up at a steady rate each
year; instead, the quantitative change of rising temperatures appear poised to
transition to a phase of qualitatively different, accelerated climate change.
The only solution to the crisis of global warming is a drastic reduction in
greenhouse gas emissions
