IPCC February 2007 Report - November 19, 2008
GLOBAL WARMING
Industrialization, deforestation, and pollution have greatly increased atmospheric concentrations of water vapor, carbon dioxide, methane, and nitrous oxide, all greenhouse gases that help trap heat near Earth's surface.
Humans are pouring carbon dioxide into the atmosphere much faster than plants and oceans can absorb it.
• These gases persist in the atmosphere for years, meaning that even if such emissions were eliminated today, it would not immediately stop global warming.
What's Going to Happen?
A follow-up report by the IPCC released in April 2007 warned that global warming could lead to large-scale food and water shortages and have catastrophic effects on wildlife.
• Sea level could rise between 7 and 23 inches (18 to 59 centimeters) by century's end, the IPCC's February 2007 report projects. Rises of just 4 inches (10 centimeters) could flood many South Seas islands and swamp large parts of Southeast Asia.
• Some hundred million people live within 3 feet (1 meter) of mean sea level, and much of the world's population is concentrated in vulnerable coastal cities. In the U.S., Louisiana and Florida are especially at risk.
• Glaciers around the world could melt, causing sea levels to rise while creating water shortages in regions dependent on runoff for fresh water.
• Strong hurricanes, droughts, heat waves, wildfires, and other natural disasters may become commonplace in many parts of the world. The growth of deserts may also cause food shortages in many places.
• More than a million species face extinction from disappearing habitat, changing ecosystems, and acidifying oceans.
• The ocean's circulation system, known as the ocean conveyor belt, could be permanently altered, causing a mini-ice age in Western Europe and other rapid changes.
• At some point in the future, warming could become uncontrollable by creating a so-called positive feedback effect. Rising temperatures could release additional greenhouse gases by unlocking methane in permafrost and undersea deposits, freeing carbon trapped in sea ice, and causing increased evaporation of water.

Recently I received an e-mail from a reader who asked me what I thought about "global warming."
I think that global warming is an observable, measurable phenomenon. From a hobo's perspective, that is, spending a good deal of time outdoors, I have personally observed that summer and winter have been warmer than I remember them as a child or even a teenager. I actually was aware of the changes in climate before I'd heard the terms "global warming" and "global climate change."
As to the question of whether human activity has caused the climate to warm; I think that this is quite likely although there may be room for an agrument that part of this warming effect is an element of a natural cycle.
Common sense tells me, as a layman, that I cannot pollute earth's atmoshere and get away with it indefinitely. An old prison inmate adage says; "If you play you gotta pay."
Unfortunately, the issue of global warming is being defined by special interest groups instead of the individual human conscience. That global climate change is occurring is not in question for most people. The main points of contention seem to be; what should we do about it and when, and, who will govern our action.
These are questions that can be referred to, as the AA people say, your "higher power" if you have one. In addition, you may rely on your own wisdom to guide you. You can also rely on the corporate "common sense" of the special interest groups focused on the issue of global warming.
I frequently confer with the God of the Bible as my "higher power." He has been the only "spiritual" medium that has taken the time to answer my questions and offer me direction for the road I'm on. I am totally satisfied with His performance to date. I am able to ask Him specific questions in real time and receive real, relevant answers that I can understand. Pretty cool huh?
I gotta go. Till next week, this is the Hobo's perspective. Have a great week.
