You might think an angelfish in the waters off Massachusetts is one confused and chilly little tropical critter, unless you know that scientists have watched ocean temperatures rising since 1975. Check out the new seven-part web feature on oceans and human-caused climate change, featuring our own scientists and Doug's son Chris Rader, a marine biologist in the Florida Keys. The feature gives you a run-down of solutions and science, including the basics of glaciers, ecosystems and the ocean's "conveyor belt." What were you doing the year that corals were bleaching in nearly every ocean during the warmest 12-month span on record? Piece - http://www.oceansalive.org/explore.c...contentID=4704. Now, Chuck, you know darn good and well that there isn't such a thing as global warming. That's just something those unpatriotic, terrorist loving, well educated, liberal scientists are using to undermine the war on terror in Iraq. Now, everybody back in line, and goose step. I'm blaming my new depthsounder, but I have been getting summer water temperature readings that are consistently 1 degree higher and in some cases 2-3 degrees higher than readings in the same areas in previous years. It isn't unusual to have one warm year, or one cool year, and the climate does fluctuate- but we shouldn't be willing to accept any extreme amount of change we observe as a natural phenomenon. The ozone "hole" is a good example; since the use of CFC's was generally banned the hole seems to be repairing itself. (Although some free marketeers would claim the ozone hole would have stabilized, anyway, and that removing certain chemical compounds from the environment had nothing to do with it. You can still find people to insist there's no medical evidence linking smoking with lung cancer, too) Changes in the ocean environment certainly impact how we use and enjoy our boats. Small changes can effect the number of fish, and even the species of fish, available to catch. A trend of generally warmer water temps have played hell with out Pacific NW salmon runs for several years, although we did enjoy a couple of years where the temps dropped parially back toward the historic norms and we had (relatively)adequate runs of fish. Oceans (as well as green plants on shore) are vital to the existence of life as we know it on this planet. There is always a chance that just maybe some guy grousing one minute about how salmon fishing ain't what it used to be and gd'ing "them liberal environmentalists and their global warming crap" the next isn't seeing the big picture. The question is not global warming, but the cause. Is it the natural cycles of earth, or something else? How much is man to blame? 10k years ago was a mini ice age, what did man do to cause it? 1860 or there abouts 20 miles of glacier in Glacier Bay meltet. And has not come back. What caused this warming? Mt. St. Helens spewed more ozone killing chemicals in one eruption than man put up in 10-20 years. The same "Enviromentalists" were saying global cooling in 1970. When that grant money dried up, they are now touting man caused global warming. Maybe it is grant money that causes the problems. Does not seem to bring solutions. Which part of human life is causing the decrease in the earth's magnetic field? Another good explanation for causes of "global warming" "Blame it on the Sun So what drives global climate, if not greenhouse gas concentrations? Well, maybe it's the sun. There are three variables affecting the Earth's orbit--orbit shape, tilt, and wobble--which profoundly affect weather patterns. The Earth's orbit does not form a circle as it moves around the sun--it forms an ellipse, passing further away from the sun at one end of the orbit than it does at the other end. During a 100,000-year cycle, the tug of other planets on the Earth causes its orbit to change shape. It shifts from a short, broad ellipse that keeps the Earth closer to the sun, to a long flat ellipse that allows it to move farther from the sun and back again. At the same time the Earth is orbiting, it also spins around an axis that tilts lower and then higher during a 41,000-year cycle. Close to the poles, the contrast between winter and summer is greatest when the tilt is large. The Earth wobbles because it is spinning around an axis that tilts back and forth. Thus, a temperature drop occurs in the Northern Hemisphere when it tilts away from the sun; then the same thing happens in the Southern Hemisphere and again in the North, in a 22,000-year cycle. We know from simple physics that the additional energy added to the climate system by the doubling of atmospheric CO2 is about four watts per square meter (W/m2)--a very small amount of energy when compared to the 342 watts per square meter added by the sun's radiation at the top of the atmosphere, and small also when compared to natural variations in the amount of radiation the sun sends toward the Earth. The possible increase in energy stored in the atmosphere due to human activity is also small when compared to uncertainties in the computer simulations of the Earth's climate used to predict global warming. For example, knowledge of the amount of energy flowing from the equator to the poles is uncertain by an amount equivalent to 25 to 30 W/m2. The amount of sunlight absorbed by the atmosphere or reflected by the surface is also uncertain, by as much as 25 W/m2. Some computer models include adjustments to the energy flows of as much as 100 W/m2. Imprecise treatment of the effect of clouds may introduce another 25 W/m2 of uncertainty into the basic computations. (2) These uncertainties are many times larger than the four W/m2 input of energy believed to result from a doubling of CO2 concentration in the atmosphere. It is difficult to see how the climate impact of the four W/m2 can be accurately calculated in the face of such huge uncertainties. As a consequence, forecasts based on the computer simulations of climate may not even be meaningful at this time." http://www.heartland.org/Article.cfm?artId=15726 Of course harry, kevin and crowd will "blame it on Bush" like they do everything else......regardless of the facts |
