El Nino and La Nina, are relative and go from altering to neutral from year to year. Deforestation; we need the trees to keep the air clean, but I just didn't think we were there yet on that one, though "please stop taking our trees down" people, you are ruining our pasture lands where I live. If you live where I live, at least trim them around the power lines, because I really like to keep power during snowmageddon or icemageddon. Land use and land cover....I think if we maintain the trees and limit their removal during construction that would be helpful. Aerosols, I can see that some. Melting Ice and Volcanic Eruptions; I think the ice melt varies by seasons, decades and centuries. Extreme Volcano's like from Iceland can have a severe impact on air travel. If a super volcano erupted, like in Yellowstone park, well then it would be... less
Mrs TAdding to my last comment - On Yellowstone park, if the super volcano erupted it would be the end. On Melting Ice, I'm glad scientists can now measure the activity of our polar ice caps and their rate of melting or freezing and have a good database to... moreAdding to my last comment - On Yellowstone park, if the super volcano erupted it would be the end. On Melting Ice, I'm glad scientists can now measure the activity of our polar ice caps and their rate of melting or freezing and have a good database to really determine the potential future.
Mrs TOn Aerosols, defiantly an issue, but I think environmentalists have made good progress in lowering the aerosol levels in the past 30 years. The sun and moon, defiantly affect many weather and temperature events on the earth. Sun spots, no sun spots,... moreOn Aerosols, defiantly an issue, but I think environmentalists have made good progress in lowering the aerosol levels in the past 30 years. The sun and moon, defiantly affect many weather and temperature events on the earth. Sun spots, no sun spots, more or less radiation. The position of the moon and it's affects on the ocean tides and patterns, as well as the weather is an interesting topic to study aloneless
