      The time between peak temperatures can be used to measure climate change. Global warming is expected to decrease those times. Since it was 12 years since the hottest year on record, the next value might be 7 years, then 5 years, and so on. Without climate change those times would be a function of the length of recorded temperatures and would usually increase in duration as more data was recorded (40 yrs to 50 years to 80 years, etc.).

      It is saddening that people are even arguing this. You don't grasp the complexity of the problem. The reason we believe global warming occurs is that many different readings -not all- point in the same direction. All measurements, regardless of their duration are subject to random deviations, which by definition have random durations. Some probably have durations measured in millions of years.

    I think we are in the interesting part of Climate change right now. Energy levels (not temperature) have increased dramatically in a rather short time and the climate is trying to find a place for all that extra energy now. So the oceans are cycling rapidly (Nina/Nino phases), precipitation levels etc are changing. In essence we're cycling rapidly between extremes. Anecdotally in Utah, last year we had the largest snows on record, and this year is probably the driest on record. For my entire childhood (I'm nearly 40) these cycles were nearly a decade long now they are a cycling in a year.

    This will probably continue for a decade or three as the system tries to stabilize the energy levels and sink some of the temperature increase into the oceans, etc. The models aren't perfect and the deniers point to that, but the reality is we simply don't know how the climate will stabilize these energy levels, we can only make predictions based on previous climates we have rudimentary knowledge of. I'll likely be dead long before the worst of climate change hits (major shifts in breadbasket areas), but I know I'm going to live during the most erratic climate change this world's ever seen.

    The scariest part to me is how to plan for the future because there is one thing the models do predict and that's the bad weather (the kind that kills people) is going to increase dramatically. I was hoping the SW would get wetter as the models predict but it appears, at least during my lifetime, things are just going to get more erratic making it very difficult to predict and manage scarce water resources.

    The funniest part about Climate Change and the Deniers is that the government is planning for it. The military and defense planners and many others are planning for summers where the Arctic passage that's never existed becomes a reality. And before people say this is because of Obama I'll point out this planning started under GW Bush. Those in the know and with power and influence are causing our government to react like Climate change is not only a reality but something that's very important strategically including how to get to all that oil that's in the arctic that no one ever thought would be accessible. This includes a certain pair of brothers that are highly invested in carbon based energy and fund much if not all of the deniers making plans to drill and tap that oil when the ice melts permanently.
