All the curves that are fit to print

Regarding the latest UAH and RSS global temperature data plots Dave B writes: “…could you post a best-fit, to be fair? I don’t have the technology.”

Sometimes I’m tempted to tell people to do the work themselves, after all, I’m overloaded as it is. But, it is the 4th of July weekend, and I’m stuck here in the smoky toasty Sacramento Valley babysitting a bunch of servers until my chief tech support guy comes back from vacation, so what the heck.

I’m not sure what he’s implying by “fair” but it has been my experience that no matter what you put in a graph, or how you graph it, somebody will find fault with it.  Below are raw data overlaid with 1st order and 5th order curve fits to show long and short term trends.

And “to be fair”, and to make everyone happy/angry here is the last 11 years, when the warming trend flattened.

Have at it lads. :-)





Charlotte smashes 123 year record low temperature

GREG LACOUR, The Charolotte Observer

This morning was downright cool in the Charlotte region — cool enough to break a record that had stood for more than a century.The temperature at Charlotte/Douglas International Airport was 56 at about 5:30 a.m., breaking the July 2 record of 58, set in 1885. The normal low for this time of year is 70.

It’ll warm up quickly today, though. Temperatures today are expected to peak at 90 degrees, according to the National Weather Service. But it’ll still feel pleasant because of humidity levels between 20 and 25 percent, said NWS meteorologist Doug Outlaw.

Conditions will be cool again overnight, with the low descending to 59, one degree warmer than the record for July 3, set in 1932. And the Fourth of July is expected to be warm and dry, with a high of 92 and “a very, very minimal chance” of rain, Outlaw said.

Forecasters don’t expect any rain until Saturday afternoon, when they call for a 40 percent chance of showers and thunderstorms.
