April was coolest one since 1999 [Tucson: About that Gore-Bull Warming]

Arizona Daily Star ^

This April was the coolest one in Tucson since 1999, the National Weather Service reported Monday.

The average temperature for April 2010 was 65.4 degrees, slightly cooler than the normal average April temperature, 66 degrees, the weather service reported. The official recording for rainfall also was slightly below normal. The station at Tucson International Airport received 0.23 inches of rain in April, compared to a normal of 0.28.

The temperature still hasn’t officially hit 90 degrees in Tucson, which is very late compared to recent years. Since 2000, the average first 90 degree temperature has been on March 26th.

The high temperature could hit 90 on Tuesday or Wednesday, the service forecasts. Either day would be among the dozen latest dates for a year’s first 90-degree temperature in recorded Tucson history.

The latest 90-degree temperature ever recorded in Tucson was on May 16 in both 1933 and 1905.

We had a nice snowstorm here in northern Arizona yesterday. Cool! I mean, Cold!

[SandRat]

So Al Bore... about this Gore-Bull Warming.

[Rushmore Rocks]

More snow predicted here in the Black Hills of South Dakota for Wednesday and Thursday. After this winter, I’m really ready for some Gorebull warming.

[Inspectorette]

Tomorrow, Portland, Oregon is predicting a record low for the high for May 4. Record low for the day’s high temp was 52 degrees in 1950. Tomorrow’s high temp is predicted to be 51.

FORT WORTH.

THE AC IS ALWAYS ON BY MAY.

NOT THIS YEAR, (thank you dufus Agore).

We've been in a flat or declining temperature trend since 1995. And before that, what little warming there was could have easily been linked to increased solar activity. The Sun was more active during the period between about 1930 and 2000 than at anytime in the past 1,000 or so years (during peaks of the 11-year sunspot cycle).

From BBC News [yr: 2004]:
"A new [2004] analysis shows that the Sun is more active now than it has been at anytime in the previous 1,000 years. Scientists based at the Institute for Astronomy in Zurich used ice cores from Greenland to construct a picture of our star's activity in the past. They say that over the last century the number of sunspots rose at the same time that the Earth's climate became steadily warmer."..."In particular, it has been noted that between about 1645 and 1715, few sunspots were seen on the Sun's surface.

This period is called the Maunder Minimum after the English astronomer who studied it. It coincided with a spell of prolonged cold weather often referred to as the "Little Ice Age". Solar scientists strongly suspect there is a link between the two events - but the exact mechanism remains elusive."

Here's a sunspot chart showing the various peaks and dips throughout the past centuries. Note the "Medieval Max". It corresponds to the "Medieval Warm Period". The "Maunder Minimum" corresponds to the "Little Ice Age", and the "Modern Max" to the recent warming trend we had been experiencing, at least until the past 15 years or so.

"Changes in carbon-14 concentration in the Earth's atmosphere, which serves as a long term proxy of solar activity. Note the present day is on the left-hand side of this figure."

Well...Oregon had the rainiest month on record...25 days of rain....it’s been GLOOMY...

[SandRat]

Developed Webbed feet yet with all the rain?

[Caipirabob]

The weather’s been wonderful this spring. We’ll see how I feel about it all when I experience my second summer here in about6-7 weeks....

[goodnesswins]

HA...I’m from western WASHINGTON, the State....I already have webbed feet!

[SandRat]

Remember, that there are all kinds of places near Phoenix, or Tucson that you can go to cool off.

Last February I was emailing back and forth with some guys from Boston I work with occasionally. I told them, after living my entire life in Texas, for the first time, I'm considering moving somewhere warmer.

The mall?

[SandRat]

Mt Lemon, Ramsey Canyon, USrey Moutain Recreation Area, to name jus three.
