I actually think a bit of panic is a good idea. The reason I say that is we are already late and many people seem to think we still have a lot of time. Scientists report based on collected data but that data is already old when they publish. What people don't realize is that the scientists in an effort to please climate change skeptics and doubters have taken pains to be absolutely sure of their conclusions even when that is almost impossible. So they underestimate their conclusions.
Scientists are asked to predict what will happen and then get attacked for saying what they think will happen. Look at that graph! Isnt it pretty obvious? Yet some politician or fossil fuel lobbyist demand proof that Scientists can guarantee that trend will continue to happen. Well scientists can't do that. So they wait to make their conclusions until they can be sure. Meanwhile those conclusions may already have started happening because of the 'caution delay' in publishing the collected data.
It shouldn't be this warm so soon. I bet most people expect that sooner or later that there will be more normal winters again (snowier anyway). But what happens if we never have our old winters ever again? Is that time to panic? When the polar ice cap began melting away that was the time to panic but we took it in stride and morons talked about climate change was a cycle and it was happening on Mars!
It is long past time to panic. I say that because we are avoiding facing how bad it already is and how fast it is worsening. There is the inertia encountered when trying to affect so large a system. We took decades of profligate environmental abuse to get here and it will not be easy to stop that abuse quickly and it will still take time (inertia) for the system to show the beneficial effects.
Yeah time to panic. We may have seen the last winter... and missed noticing it since it was a couple or so years ago.
