"Global Green USA" flunks math

If they were real scientists, they would be able to convert millimeters into feet and inches. They use both measurement methods but are obviously unaware that 200mm converts to about 8"

Among other challenges, climate change is causing our sea levels to rise and putting our coastal cities -- and billions of people -- at risk across the globe.

SEA LEVEL RISE: RAPID ICE SHELF MELTING

Below, some alarming facts about the increasingly rapid rate of ice shelf melting.

* Sea level has risen four to 10 inches this past century and is projected to rise up to three feet by 2100.

* For every foot of sea level rise, we can expect about 100 feet of coastal flooding.

* As much as 33% of coastal land and wetland habitats are likely to be lost in the next hundred years if the level of the ocean continues to rise at its present rate. (Source)

* Sea level has risen by more than two millimeters per year on average since the late 19th century, the steepest rate for more than 2,100 years. (Source)

* The Greenland and Antarctic ice sheets are losing mass at an accelerating pace. The findings of a NASA-funded satellite study indicate that these ice sheets are overtaking ice loss from Earth's mountain glaciers and ice caps to become the dominant contributor to global sea level rise -- much sooner than model forecasts have predicted.

A reply from James Macdonald [jmac0013@cox.net], a retired meteorologist

Your article on sea level rise contains ridiculous predictions. Based on the present rate of sea level rise, which even your article pegs at about 2 millimeters per year, the rise for the next century would only be about 8 inches, not three feet! Statements that it is accelerating are pure nonsense. Worldwide, there has been no warming in the last 14 years. Only in the United States have we had a warm year so far after a very cold winter two years ago. At the same time the Arctic regions have been colder than normal for the past 12 months. The Southern hemisphere has also had no warming. The major icecaps are not melting and the South Pole ice is getting thicker..

This all adds up to no acceleration of sea level rise. No one knows whether our climate will get warmer or colder in the next century. This will be governed by the sun and the ocean oscillations.
