Got this post earlier today from Adam :
Yes, there are all kinds of records, record highs and record lows. There were a number of record lows this past winter.
But the number of record highs has been outnumbering record lows in the past 20-30 years, and particularly this year. See for example:
which shows both long-term and short-term trends. So yes, we are still seeing record lows, but a lot more record highs, and an increasing ratio of highs to lows with each decade.
That is exactly the behaviour we would expect from Urban Heat Islands. Phoenix, Arizona is often 15 degrees hotter at night than the surrounding desert. Denver can be 20 degrees warmer during the winter than surrounding areas at the same elevation.
Furthermore, measuring the heat of the planet by measuring air temperature is like measuring your body temperature at your big toe: it’s correlated, but very weakly. The oceans have roughly the same thickness and 500 times the density of the atmosphere at sea level, and average sea level is a terrific measure of average ocean temperature. After 8000 years of stagnation, sea level has risen first slowly then more rapidly over the past 130 years, and the more accurately we measure its average level, the smoother and more monotonic the rise.
Better to look at the correct graph before making ridiculous comments. Sea level has risen 15 metres during the last 8,000 years. Over the last eight years it has hardly risen at all.
The planet is warming. We are causing it. Get over it.
The planet’s temperature changes as much as 12C on a regular basis. How can any educated person claim that a 0.65C rise is due to man? That amount is less than measurement error in the paleo data.
