From the article: Is Global Warming Affecting Pollen Allergies?
Do you think that there is significant global warming? If the earth truly is warming, we might expect a "greenhouse" effect, causing the increased growth of plants as well as an increase in the pollination of these plants. We might also expect the pollinating seasons of these plants, such as spring and fall, to occur earlier in the year and to last longer. Have you noticed a change in your allergies over the years?
