From the BBC

http://www.bbc.co.uk/news/world-us-canada-40361374

"Summer has only just begun but a record-breaking heatwave in the southwest corner of the US has sparked wildfires and triggered power outages.

There were 15 large blazes burning in Arizona, California, New Mexico and Utah on Wednesday.

And intermittent blackouts were reported in a number of southwest cities and towns as the spike in demand for electricity to run air-conditioning units overloads power systems.

But what are the more unlikely ways the blistering conditions are affecting the region?"

* Driving with oven gloves

* Melting mail

* Swimming scorpions

* Planes grounded

* Free ice cream

* And, of course, eggs cooking outside

When they talk about triple digit temperature (> 100), they mean above 38 degrees Celsius

I have to say I am somewhat disappointed in global warming so far.

I still can't grow tropical fruit at home;
The snapper still leave Tasman Bay during the winter; and
It's still too cold for tropical game-fish like Mahi Mahi and Wahoo.

Why can't we just have global warming in winter?

Not to mention that its still too cold during winter for my wifes body parts not to go into hibernation, roll on the balmy evenings...........

Planes grounded is more about economics than anything else.

Higher temperatures mean thinner air which means less lift. That in turn means lower maximum takeoff weight. So, to take enough fuel for the flight, you have to reduce the payload (passengers or freight), which reduces profit. Eventually, it gets cheaper to cancel a flight completely rather than fly half-empty.

I was surprised to find that Phoenix isn't particularly high (only about 1,000ft above seal level), so you could expect this to expand to other airports.

Yah... it's actually an energy storage problem. Store excess heat in summer, release it in winter.

Exactly. That's the problem season for fruit and fish.

Today 43 degrees C at 7 pm at night in Phoenix.

I think it's little too warm with just an open window and a fan

So, none of these things ever happened before 'global warming'?

Please keep up. It's now called 'Climate Change' because it was getting hard to explain the freezing temperatures. Is it happening, yes. Has the earth always warmed and cooled, yes. Was one of the hottest periods on earth when the dinosaurs were around, yes. Do humans cause it....ummmmm most would have you think so and I am not going to start that 'discussion' here.

I think we need a global heat transfer kit. Take the warm air from one side of the planet and pump it into the other. Just switch 'er into reverse every 6 months. Now the next question is DVS or HRV...who does it better?

Lazy is such an ugly word, I prefer to call it selective participation

Warming means there is an increase in the Earths temperature. It means different weather, as more heat causes more evaporation, more rain. The more weather means some locations get wetter or drier and that affects local temps in any given weather bomb situation.

Id say ChCh has cooled, the summers were hotter more often and winters were mild, snow if you were lucky was slush. All of that is cooler now. I look at it that depending on where you are, temperate, semi tropical, tropical and if its large land mass or like us, it just changes the weather, for better for for worse.

That's pretty much what "record breaking" means.

A record is there to be beaten. How long have we been keeping records for?
Maybe the earth has a broader climate cycle and we are just going through a warmer patch of one? Oh yeah it does, ice age wasnt that long ago. like 2004 or something. Cant remember.

XKCD lays it out better than I can. History is long. The current changes are unprecedented.
