Denver's low maximum temperature daily double

Bitterly cold Eyre sets new WA record

Eyre in the Eucla set a new mark for the coldest temperature ever recorded in Western Australia, minus 7.2 degrees.

Why is this site so obsessed with short term extrema? All this will do is reinforce crackpot opinions on long term climate change on the basis of irrelevant weather noise.
REPLY: “Beaker”, my business, my life, my job, is weather, weather reporting and weather instrumentation. I find weather events interesting, and if you’ll look back into the archives you’ll see that I’ve reported on interesting weather events long before this site became focused on climate change issues.
I take exception to your “crackpot” name calling. If you wish to hurl insults, have the courage at least to step out from behind the mask of the anonymous coward when doing so.
If I had said something totally unfounded like “This cold snap in Denver proves the entire AGW theory wrong.” then perhaps a label like “crackpot” would fit. However, the word “climate” as a focus does not even exist in the post (except for the amusing end quote from Heinlien) and the tags say only “weather”.

Here in Jackson, Michigan, we have only had one day in the 90’s back in early June, which is very unusual. My neighbors have an above ground pool, a couple of years ago they were in it all summer long, this year, it has only gotten warm enough for a couple of days.
My wife doesn’t get too happy though, when I predict our first snow to come sometime in September.

Why is this site so obsessed with short term extrema?
Because weather extrema is an equally valid measure of climate direction/trend as the average. Arguably its a better measure because extremes are less prone to systematic error.
The crackpot opinions are coming from those like you, beaker, who don’t understand basic statistics.

“Why is this site so obsessed with short term extrema? All this will do is reinforce crackpot opinions on long term climate change on the basis of irrelevant weather noise.”
Beaker,
Here are a ew answers to your questions:
1)The AGW Crowd itself uses short term weather events as proof of AGW. If you doubt me, please Google any number of recent weather events (August Heatwaves, floods, droughts, tropical storms, periods of warm winters, etc..) and you will most read a quote from a climatologist, NOAA official, or a local professor saying said event is proof of AGW or Climate Change. Anthony is just doing the same. You cannot have it both ways.
2)Dr Hansen warned that runaway GHG concentrations are so high that the earth will be passing through a “tipping point” within a decade. The last time that I heard him utter this warning was last year (2007). Which means he expects the process of runaway positive feedbacks to begin no later than 2017. As far as I know Hansen hasn’t recanted or at the very least reassesed his prediction. So, 2017 is only 9 years away (short term), and it would be important to investigate short term weather events for signs of runaway positive feedbacks. Currently, everyone is looking at the Artic; I suppose most true-believers are waiting for an ice free artic to begin the process. But there are other things to watch for. I think we should keep a weather eye on the Pacific (after-all, this is the one area that has been proven to affect weather and climate worldwide). Another area to look at is the semi-permanent pressure cells. In a warming world, the northen mid-latitude cold lows will give way to the Hadley Cell, as tropical/subtropical highs would build far poleward. Places like the Rockies in North America, and North Atlantic/North Sea in Europe would see much warmer weather year around. Summers like Europe saw in 2003, or the US saw in 1980, 1988, and 2004 would be normal. For North America, the incidence of severe weather (especially in the Spring) would be way down as the polar front jet would be botteled up in Central Canada.

Mr beaker, There is enough sillyness on both sides of the climate change issue. You might look instead at the 400k and 600k year temperature graphs. You might consider the narrow appearance of the temperature peaks. Suppose the MWP as actually the peak for this 100k and 1999 was the last gasp for warm temperatures. Finally consider that AGW is the noise.
What is to be said for the billion$ $pent and to be $pent on what may be nothing more than “short term extrema” that might “reinforce crackpot opinions.”

Hey beaker,
I am an unlearned weather junkie but even I know that climate is study of short term weather extrema on a long term basis. I like to study the short term weather and realize that some of the climate scientists only recognize 30 year old data as being worthy of climate study an most anything younger than that is merely weather noise. I disagree in that there are or should be 2 areas of study long term climate and short term climate. Long term consisting of what we have now and short term consisting of a rolling average of the recent past 30 years as compared to the past record.
beaker trends have to start somewhere and we can not discount the recent weather as not counting due to the fact that we have to be prepared for weather. I would hate to eliminate the current energy supply and find my self in a very cold short term (for now) cold era.
I don’t argue with you that maybe we make to much of short term variables but then so do the warmist make to much of short term variables. They count in both directions.
Just my 2 cents.

“What are the chances of a little snow in Denver in late August?
Especially if Al Gore is in town.”
If algore shows up, 100% chance of the first snow ever in August in Denver 😉

Climate change is the trend line based on the average of the noise. So we talk about noise. Right now the noise is cooler, so the trend line will likely continue to stall as it has for the last 10 years.
However, if warmers really want to figure a trend line without noise, pick out 1998 and toss it away as an example of extreme noise. Then re-figure the trend line. Hey…it was your suggestion.

OT: We are in the beginning of another round of high speed solar wind (which shoots cosmic rays our way) as the repeating Sun’s coronal hole faces Earth. While the Sun is blank of sunspots, it is still active through its coronal holes. Will probably see Northern Lights with this rotation. Planetary K indices are already up so I will be watching cosmic ray and ozone measures to see what happens. Since the Sun is somewhat dim in the UV light spectrum but cosmic rays are strong, we should see a net ozone loss wherever cosmic rays hit hardest or most steady if the theory is correct.

Climatic autumn’s hold in Northern California is unmistakable. Only the most hardy deciduous species are still completely green leafed. Some are now showing early October levels of fall color. This cannot be attributed to drought stress alone. Cold nights, and, of course, the photons which never arrived, due to the smoke, must factor prominently.
