Natural Science 301 Guidelines

This is an open forum area for all members for discussions on all issues of science and origins. This area will and does get volatile at times, but we ask that it be kept to a dull roar, and moderators will intervene to keep the peace if necessary. This means obvious trolling and flaming that becomes a problem will be dealt with, and you might find yourself in the doghouse.

    This may be part of hypothetical reason assuming nuclear testing would continue and increase, but the science of climatic cycles, was the main reason scientists proposed the possibility of an impending Ice Age. The data has been considerably refined since, and the view toward the possibility and timing of the possible Ice Age is refined as more scientific knowledge figures into the calculations. This is not a classic hysterical Dooms Day scenario except in the popular press, and not really the subject of the thread.

    Actually, when you compare the data from the known geologic cyclic climatic data we should be entering an Ice Age, but something happened in the last ~20,000 years or so, and not related to human influence. Instead of entering another Ice Age, the climatic cycles plateaued and stayed warm. The data in this period indicated a gently warming curve up in this plateau to the Holocene climatic warm period, and then a slow average decline since with a little Ice Age. The human effect of global climate change has complicated the picture, but for some natural reason we did not enter the normal trend to an Ice Age.

      Yes, it was based on a continuation of nuclear testing. I think (but I can't be sure since I was very young) that it was one of the reasons for the pressure to end nuke testing.

      Well, that's the question. What were humans doing 10-, 15-, 20,000 years ago that might have influenced climate? There are various possibilities - agriculture, forest clearance (slash or burn), coppicing, hunting large grazers to extinction, introducing invasive species - that would have affected whole ecosystems and may have affected climate.

        Also the increasing amount of particulates in air pollution. Regulating PM-10 (10 micron particulate matter) a la the U.S. Clean Air Acts (don't know about other developed nations) allowed more sunlight to reach Earth's surface.

        Remember Pinatubo?

        P.S. I seriously doubt Paleo- and Neolithic H. sapiens populations of around 1 million doing slash-and-burn could have affected climate 10 or 20 Ka.

            Aparently the UN is having a summit soon to talk about the problems of exces antibiotic use. It's a real shame that 80% of antibiotics go to fattening animals. Overuse to "treat" viral infections and to purify wastewater ar also problems. I personaly think antibiotic resistance is the worst thret to human wel-being in the next several decades. Next ar warfare, resource depeletion, and climat change.

              I tend to agree. There are several modern medical/hygiene issues and trends that are creating a possible impending health crisis. The over use of antibiotics is the biggest elephant in the room, but this is compounded by a fanatical paranoia of cleanliness, especially for children in the west. I grew up on a farm where we played in everything from mud to manure. As we grew up with my neighbor friends, my fellow siblings and cousins, virtually none of us had serious asthma problems, and rarely got sick, except for the normal childhood diseases. I also developed a very mild reaction to insect stings.

              Recently the FDA has banned certain chemicals in hand cleansers, because of health risks, which is a possitive move in the right direction.
