We have become so dependent upon air travel that when a major route is take out of the equation, Americans can't get out of Europe and Europeans can't get home from America. Hundreds of millions of dollars are being lost by people unable to get to where they need to be and it is unclear when this situation will abate.
Aside from a boat, the only way to get from London to the U.S. is to take a train to Rome, fly to Hong Kong, then across the Pacific to the U.S. Unfortunately the trains have been jammed with Europeans trying to get from country to country because they can't fly.
Although it seems like Mother Earth is cranky with us, what with all those earthquakes and volcanoes, according to the U.S. Geologic Survey: "Since 1900, an average of 16 magnitude 7 or greater earthquakes - the size that seismologists define as major - have occurred worldwide each year. With six major earthquakes striking in the first four months of this year, 2010 is well within the normal range."
One last thing about volcanoes. All that ash and sludge they push into the atmosphere tends to stay there for a while.
According to San Diego State University, when Mount Pinatubo erupted in the Philippines in 1991, it shoved so much Sulfur Dioxide into the atmosphere that the Earth's temperature dropped an average two degrees for two years.
The strongest volcanic eruption in the past 1,000 years is believed to have been Mt. Tamborain Indonesia in April of 1815. According to the Christian Science Monitor:
The eruption of Mt. Tambora cast a veil of ash around the world, lowering global temperatures by more than 5 degrees Fahrenheit. The result was the "year without a summer" in 1816."
A couple of decent volcanoes per decade and our global warming problem would appear to be solved.
