More difficult? You couldn't do it before...because you don't know what you're talking about. The Earth is such an impossibly complex system, that all your little models are like ancient maps of the Earth-centered universe. Curious, but baseless. Stop pushing your inadequate theories and climate fantasies as science.
Nobody knows the troubles I’ve seen.
Isn't that where man usually starts before he masters a science? Little models that don't quite pan out until new mathematics and physics are created to understand and predict phenomenon? I do not agree with Al Gore and company but I know all this research and science will be put to good use in the future once the chaff is blown away.
