What’s with all the threatening volcanoes lately? Over the weekend news about Mt. Redoubt in Alaska that threatened the most populated area around Anchorage, was followed by England’s unusually cold winter with the most snow in 18 years. While, this morning 3 different volcanoes in Japan are spewing, as well as a Mt. Karymsky in Russia!

So far, so good. No one is hurt. Ash spitting volcanoes can swamp a city to its rooftops. It’s like an impure avalanche that just blankets people, houses, and streets, and adds to earth’s dilemma. Volcanic activity adds to the ozone effect, the greenhouse effect, and haze effect where particulates partially block the sun causing an overall cooling. In other words, while they may be a good belch for the earth, they are not good for the environment or us.
Â
Researchers also recently found that volcano activity tends to cool the tropics for years afterward. The 20th century didn’t have too much volcanic activity, and global warming may have stopped that cooling as well as squelch some volcanoes from belching.
Â
I think that it’s only logic that as scientists work together worldwide and compile their findings about climate change relative to gulf streams, water surface temps, ice melt, drought, rainfall, volcanoes, earthquakes, etc., we will find that the impact on each other is greater than we once thought, and that the whole thing can indeed be thrown off kilter by excess or lack of component parts of the whole, like gases.Â
