They're making a big deal out of it but note that they say this is the 1st time that water has been accurately measured. They have nothing to compare it to. Many volcanoes in the past could have easily put a lot more water than this in the air but they didn't measure it to know. Science is discovering and measuring it accurately. Political activism is using scare tactics to make it more than it is.
This is similar to the hoop de do about the ozone hole when they said that freon was causing it go grow. It wasn't even discovered until the '70's and they had no idea how big it was before that. It could have as easily been much smaller than normal. They didn't know it was there before and had nothing to compare it to.
And they call it 'science'.
