The graph above shows the global temperature anomaly since 1979 (blue) and CO2 levels (fuchsia). There is no correlation between CO2 levels and temperatures. There are very strong historic correlations between solar activity and temperatures. Right now our sun is experiencing very mild solar activity, so expect cooler temperatures!

Average US home = 11,040 kWh/year in electricity = 6.3 tons/year of CO2 for coal powered energy.
Bloom Industries is planning to introduce a 2x3x3 foot sized off-grid unit for about $3,000 that can generate the same 11,040 kWh/year while emitting less than .01 tons/year using NG or Bio gas. Companies like Bay, Google, Fed Ex and Walt Mart already have the $700,000/box commercial sized version. Bay will recoup the cost of their 5 Bloom Boxes within 20 years and factoring in depreciation will cut energy costs by $4 million in that 20 years. It is much more reliable and cheaper than solar or wind and it won't kill birds or need all the water that is needed to keep solar panels clean.

Why don't you go help the flood victims... You do know that they are attacking non- Moslems for helping them so bring an M-16.
And after you man up and find your D&B's, do like the scarecrow and find a brain.
Again, you seem to think the weather events during your life time are some how worse than the past weather... Are you some how special or deserve special punishment?
Or do you think the weather is out to get you because of the sins of your ancestors?

but it's o.k. I know you don't understand physics.
this year has been full of events. (aka evidence) 1 percent rise is a big deal.
man up?? tell that to the survivors of Katrina, or the survivors of the Pakistan floods.
why don't you man up and travel there to help the flood victims out?
maybe then you'd get a taste of the real world effects that are actually occurring. 1% is a huge deal when talking in terms of global events.

A 1 degree average lowering of world wide temperature could be said to have these effects. You act like the weather we have is some how worse then our great grandfathers, or something. Man up boy, you're a wimp.

Now, back to my point:
There is growing empirical evidence that warming temperatures cause more intense hurricanes, heavier rainfalls and flooding, increased conditions for wildfires and dangerous heat waves.
Anonymous
Global warming is a reality already with us. The 1990s were the warmest decade on record, about 0.6 of a degree celcius (°C) warmer than 100 years ago. Australia has warmed by 0.7 °C between 1910 – 1999, with most of this increase occurring since 1950 (CSIRO, 2001).
the average for all of Australia is higher, regardless of your one record cold temperature in Perth.

Climactically or geologically who's to say what's what or who's on first?

"Winter records set in Perth"
"A winter record was also set with the mean minimum temperature for the three months hitting 6.4C."

If you only focus on hot weather that can not be attributed to man you might be a catastrophic warming hypochondriac. lol

is Lake Superior as monitored by MSU. When you check/click on the map for temperatures you get this warning:NOTICE (8/11/2010) Due to degradation of a satellite sensor used by this mapping product, some images have exhibited extreme high and low surface temperatures. Please disregard these images as anomalies. Future images will not include data from the degraded satellite and images caused by the faulty satellite sensor will be/have been removed from the image archive.
I really can't refute data that is admittedly unreliable due to sensor degradation possibly for as long as ten years. I'm not a miracle worker.

// Font Size - Increase / Decrease / Reset Data discovered on NASA's Goddard Institute for Space Studies (GISS) website revises recorded temperatures for the United States. It is expected that similar revisions will also be made for global temperature recordings. This information was discovered by Steve McIntyre of Climate Audit on Wednesday (8/8/2007). No NASA press release, no James Hansen (head of GISS) announcement, nothing. Could it be because they don't want anyone to see it? The data is certainly devastating for the Al Gore camp which has based much of their Carbon Credits sales pitch on recent temperatures (e.g. claiming that 1998 was the warmest on record).
Other aspects of the data are just as stunning.
- Only 4 of the top 10 warmest years occurred in the past 10 years (1998, 1999, 2006)
- Out of the top 10 warmest years half occurred before 1940
- The years 2000, 2002, 2003 and 2004 were cooler than the year 1900
- 1996, just two years before what Al Gore called the hottest year in the history of the planet, was actually cooler than average.
- 1921 was the third warmest year in recorded history (behind 1934 and 1998).
We're almost back to the 1970's theory of global cooling! The data clearly changes things.
Had we been living in 1934 we would have heard the same claims of global warming, this is the evidence that we would have heard at the time:
- 8 of the past 10 years had been above average.
- 1934 was the warmest year ever recorded. The warmest in over 54 years!
Shift that to 1944 and you would have seen that 17 of the past 21 years had been warmer than average. It is obvious that in just the past 125 years there have been other periods just as warm, or warmer, than what we are now experiencing. If we could look at the past 1,000 years with the accuracy of the past 100 years we would most likely find that this is not unusual at all.
Update: Turns out this NASA data was revised because of a Y2K bug in the algorithm used to adjust measurement station raw data. Blogger Finds Y2K Bug in NASA Climate Data. NASA's James Hansen has refused to release his algorithms but they were reverse engineered by Steve McIntyre of Climate Audit and NASA has since updated their data (so you know he Steve got it right). What this author finds truly disturbing (and disgusting) is that NASA would keep these algorithms secret. This is public information. Steve really should file a Freedom of Information (FOIA) request to obtain this and what ever else he needs. NASA would be very hard pressed to justify withholding that information. These events seriously call in to question anything James Hansen has touched, supervised, or managed. Not just because he got the math wrong but because he also hides his methods. He is apparently attempting to establish a new religion by requiring people to have faith in his data.

A New Leaderboard at the U.S. Open
By Steve McIntyre
A little unexpectedly, 1998 had a late bogey and 1934 had a late birdie. (I thought that they were both in the clubhouse since the turmoil seemed to be in the 2000s.) In any event, the new leader atop the U.S. Open is 1934.
2006 had a couple of late bogeys and fell to 4th place, behind even 1921. I think that there’s a little air in the 2006 numbers even within GISS procedures as the other post-2000 lost about 0.15 strokes through late bogeys, while it lost only 0.10 strokes. It is faltering and it might yet fall behind 1931 into 5th place.
Four of the top 10 are now from the 1930s: 1934, 1931, 1938 and 1939, while only 3 of the top 10 are from the last 10 years (1998, 2006, 1999). Several years (2000, 2002, 2003, 2004) fell well down the leaderboard, behind even 1900. (World rankings are calculated separately.) Note: For the new leaderboard see
. The old data has been erased; by sheer chance, I had the old data active in my R-session but I can’t give a link to it.)

Will the Real USHCN Data Set Please Stand Up?
By Steve McIntyre
The GISS homepage formerly said:
In econometrics, you couldn’t use loosy-goosy phrases like “replaced by a later corrected version.” You’d have to identify the version. Actually AGU policies (which apply to JGR) require proper data citation, although climate scientists publishing in AGU journals flout this policy, including Hansen here. Following an email to Hansen and Ruedy of GISS, they changed the introduction at the GISTEMP intro from:to the following:
This doesn’t really clarify the provenance of the data. In his email, Ruedy added:
Well, I hadn’t really “noticed” that they had used GHCN data to extend the USHCN data. I’ve done lots of cross-comparisons with different variations trying to identify exactly where the GHCN raw data came from. I’ve put up many plots at CA showing GISS raw as compared to different USHCN versions and I’ve done many more that I’ve not posted up. At his point, there’s one thing that we can say for sure: I’ve now looked at GISS raw as compared to GHCN raw data in the post-2000 period and in the few sites that I’ve examined since receiving this email (Detroit Lakes, Port Angeles), there is an exact match. So at least we’ve tracked down one aspect of the provenance of GISS raw data. I’ve done a comparison plot below for Detroit Lakes MN, a series that we’ve looked at before. After 2000, the match is exact (the delta is 0.0). However, before 2000, the USHCN TOBS/adjusted series sort of match for a while but the match tails off in the earlier portions, with the GISS raw version being quite different.

hansen48.gif
So where does the GISS raw version come from? At this stage, I think that we can declare that it doesn’t come from any of the USHCN version 2 (raw, TOBS, adjsted). If it did, then the versions would match as exactly as the GHCN raw and GISS raw after 2000. So where does it come from? Another stupid climate science guessing game, although hopefully it will solved in a shorter time than the unsolved MBH99 confidence intervals.
Ruedy’s letter has opened up the possibility of really obsolete data being used - I hadn’t thought to look at really obsolete data. I browsed through some obsolete data in connection with Swindle - who would have thought that we’d be doing so again. Two possibilities spring to mind: (1) maybe he’s using something from USHCN version 1; this is online, but I don’t think that the dates are right. (2) Maybe there’s an earlier USHCN version 2 that’s been overwritten (3) maybe he’s using an old GHCN version before 2000. Maybe none of the above - hey, it’s climate science.
