Want to discuss Science News? Global warming? H5N1 Bird Flu? Genetics? If so, come join in!
I think it would be safe to say that most people who read the news have at least heard of the H5N1 avian influenza virus. The commercial media sites are doing a pretty good job at instilling fear - sensationalizing every case of flu that might be H5N1 in origin. I sure hope that mass hysteria doesn't break out - more may die of panic and riots than the virus if this does happen.
So perhaps it is time to take a little look at what data the CDC and WHO has available. Before I am willing to join the unwashed masses in hysteria - I have a few questions.
Question 1 can be answered simply by looking at the chart below. It does appear to be recent enough - and the source is the WHO website. Please note that 160 people have been identified as infected, 85 of which died as a result. That makes it a 53% fatality rate in my book. Ok - I am concerned about the mortality rate.

The WHO does not recommend travel restrictions to any country at this time on the basis of this virus. It does recommend that people stop playing with sick or dying poultry. Ok, I think I can manage that one with ease. I never thought about playing around with sick birds - perhaps I am just too boring of a person for that one.
Tamiflu and a couple other medications (amantadine, rimantadine, oseltamivir, and zanamivir) have been touted as a treatment for the virus. However, the University of Pittsburg claims to have created a vaccination that is 100% effective upon the current strain - and did so within 1 month. They also state they can create updated versions of the vaccination to cover genetic mutations on an as-needed basis. Ok, I can deal with that. I am not a chicken farmer, and I don't play with dead birds. SO - I feel safe enough waiting for the vaccination should the great pandemic begin.
I do not believe the virus, at this time, is particularly easy to catch. Unless many different strains mutate off the virus as it is now - I really don't think we have a problem. However, if it does, we very well may have one. At least that is what the officials at the CDC and WHO is stating. Perhaps the people who actually work with birds, such as chicken farmers, should wear a mask when in direct contact with birds - whether or not they suspect illness. The chicken farmers should also entertain the possibility that regular handwashing might not be such a bad idea either. These precautions may not prevent 100% of all human contamination with the virus, but the odds of mutations are drastically reduced with a reduction in number of people contaminated in the first place. Unfortunately, I have heard of no educational program in place to prevent these people from becoming infected in the first place. This makes me scared.
Ok, now what if the great pandemic occurs? Perhaps if we are lucky, the CDC and WHO will order enough vaccinations for every person in affected areas - free of charge. I sure would hate to think that some guy without medical insurance skipped a vaccination, caught the virus, mutated the virus, and passed on the mutated virus to everyone he came in contact with over a couple bucks to cover the cost of a vaccination. At present, the WHO is only purchasing enough medication to treat 3 million people. If this does turn out to be the great pandemic, exactly HOW do they plan on going about selecting these 3 million people out of a global population that is in the trillions? No word yet on plans to purchase any vaccinations.
If money must be made, let it be made by selling the movie and book rights. I am sure those professors at the University of Pittsburg would be happy with the millions upon millions of dollars reaped for the story of the century about prevention of the disease - not counting the Nobel prize money, and worldwide fame that would come to them as well. It would be in their best long term interest, as well as that of the planet to simply publish the formula online where any country could simply produce enough to cover their own needs.

Apparently, the earth has been shifting on its axis. The north pole has moved about 1100 km in the last 10 years to the north. Perhaps some of the warm winters of the USA, and the bitter cold winters of Europe are here to stay - at least for the rest of the lives of us earthlings. Predictions exist that within 50 years, the north pole will have changed from northern Canada to Siberia.
Some points come to mind:
Now, point 4 brings some interesting thoughts up. Would not the current glaciers have to melt (raising sea levels globally) at some time - perhaps before or during buildup of new glaciers in the new "cold spots" at the polar ends of the planet?
I am not sure if the great ocean conveyor belt will be affected. Climate scientists are theorizing that the oceans conveyor belt controls our present weather patterns, keeping the northern regions of the United States and Europe warm enough to be habitable. The delicate balance between salt and water maintains the flow of the water (see bottom link) - thus if extra water is added to the oceans, such as from melting polar ice, the conveyor belt may stop. If the belt stops - a new ice age will immediately begin.
If the science communities around the world are indeed correct, how much of our global warming can be attibuted to this shift? Should the world leaders have a little chat concerning relocating people out of the new polar regions, while reclaiming tillable land that was previously untillable due to their previous location? Can or should any planning occur to deal with a stoppage of the oceanic conveyor belt?
The scientific data I am referring to comes from these sources:
