Going out yesterday made me think of the Icelandic erruption and wondered if it would have any effects on climate change. Haven't been following the news reports about it so I'm not sure just what's happening. Guess it depends how long it goes on for. Think the last one that had that kind of impact was the one back in the early 1990s that affected the atmosphere for a couple of years.

I expect it'll start the controversy going again though. It has a kind of dual effect .. creating a haze that obscures the sun a little and producing an acid aerosol effect that can affect the ozone layer .. the environmental news topic back in my younger days. It was thought then that volcanoes were the most significant cause of any global warming on the whole but that has changed because of research into the tip over balance from various inputs.

There have been improvements over the years though with a variable problem over Antarctica that I think I blogged about some time ago .. when I used to be more into writing about the subject .. because. like volcanoes there are dual effects from having the hole there or not. The hole is expected to clear up showing that we can help the environment.

Difficult to know just how to phrase things at times because often you start heading into a different subject and could .. um .. be writing for ages .. but, sometimes, things don't really fit into a few words.
