Global Warming: from Fantasy to Future
Your Own World USA, By Steve Russell and Jamie Stensrud Over the past decades, the issue of global warming has slowly moved to the forefront of humanity’s concerns about the future. Initially treated as fantasy, global warming is now a primary issue as a result of two indisputable facts: · Rising Surface Temperatures: The surface temperature of Earth has increased 0.45 – 0.6 degrees Celsius · Rising Sea Levels: The average sea level has risen globally by 10 – 25 cm over the past century. There have been at least six major extinctions on our planet in the last 600 million years, and these extinctions have eliminated 99% of all species. The reasons for these extinctions vary, but what they all have in common are dramatic changes in weather patterns and sea levels.
