October 2012: Earth's 5th warmest October on record
Posted by: Dr. Jeff Masters, 5:18 PM GMT on November 15, 2012 +36
October 2012 was the globe's 5th warmest October on record, said National Oceanic and Atmospheric Administration's National Climatic Data Center (NCDC) today. NASA rated October 2012 the 2nd warmest October on record. Global temperature records begin in 1880. October 2012 global land temperatures were the 8th warmest on record, and global ocean temperatures were the 4th warmest on record. October 2012 was the 332nd consecutive month with global temperatures warmer than the 20th century average. The last time Earth had a below-average October global temperature was in 1976, and the last below-average month of any kind was February 1985. Global satellite-measured temperatures in October 2012 for the lowest 8 km of the atmosphere were 7th or 2nd warmest in the 34-year record, according to Remote Sensing Systems and the University of Alabama Huntsville (UAH), respectively. Wunderground's weather historian, Christopher C. Burt, has a comprehensive post on the notable weather events of October 2012 in his October 2012 Global Weather Extremes Summary.


Figure 1. Departure of temperature from average for October 2012, the 5th warmest October for the globe since record keeping began in 1880. Several regions around the globe were much warmer than average, including northeastern and southwestern North America, most of South America, northern Africa, southeastern Europe, southwestern Asia, and far eastern Russia. A heat wave brought record warmth to large areas of Brazil and Bolivia. Record heat was also present in southern India. It was cooler than average in parts of northern Siberia, Mongolia, and northern China along with much of central North America. Western Canada was much cooler than average.

El Niño watch discontinued
Neutral El Niño conditions exist in the equatorial Pacific, where sea surface temperatures were 0.4°C above average as of November 12. NOAA's Climate Prediction Center (CPC) has cancelled their El Niño watch, and expects neutral El Niño conditions for the coming winter. Temperatures in the equatorial Eastern Pacific need to be 0.5°C above average or warmer to be considered an El Niño. El Niño conditions tend to bring cooler and wetter winter weather to the Southern U.S.


Figure 2. Arctic sea ice extent in October 2012 (thick black line) was the second lowest since satellite records began in 1979. Sea ice extent has sunk to the lowest values on record for this time of year during the first half of November. The previous record low occurred in 2007 (magenta line.)

Arctic sea ice falls to 2nd lowest October extent on record
Arctic sea ice extent during October reached its second lowest extent in the 35-year satellite record, behind 2007, according to the National Snow and Ice Data Center (NSIDC). Beginning in late October, Arctic sea ice extent began setting new daily record lows again, and it is very likely we will have a new monthly record low for the month of November. I have much more to say about this year's extraordinary loss of Arctic sea ice in my October 20, 2012 post, Earth's attic is on fire: Arctic sea ice bottoms out at a new record low.

The Northshore of What?

Lake Ponchartrain...sorry. I thought everybody knew I was a Louisiana boy

I've seen news about three different documentaries will or have already aired. It did not mention viewer time zones, but a quick search should tell you.

Quoting AussieStorm:
Not only is the temperature no longer rising, but one can also see the disconnect with CO2.
As far as the temperatures rising faster than forecasted, a couple of points:

1.) The only way that could happen is if they were being forecasted to fall, since they are not rising.

2.) When you compare the observed temperatures of the past 10 years against all the climate model predictions, the result should do more than raise eyebrows about how much taxpayer money is being wasted on climate science that is proving to be wrong.

Of course we know that the earth is still accumulating heat on climatic timescales. Near-surface air temperatures alone are just a part, a very small part, of all the heat reservoirs of Earth. The atmosphere/oceans/ice, when looked at on climatic timescales, continue to accumulate heat and this rate has not reduced by any level of statistical significance.

Let's just say for argument that the air temperatures of the near surface atmosphere were not warming at the expected rate. Would it not then be countered by the fact that the ice and oceans are accumulating heat at a faster-than-predicted rate?

Interestingly enough, when looking at a different source, the comparison between models used in the IPCC report and observed temperatures appears different:

Why AGW is not real:

It is impossible if the oceans are cooling. Ocean heat content is >1000000x than the atmosphere. http://bit.ly/USEOM8

In real science, theories are constantly being tested, but NO, regarding AGW, "the science is settled".

If the assertions (i.e. %u2013 polar bear population decrease) made by AGW advocates were true, they would be backed by hard data, and they are not.

If it were, the prior predictions of global climate computer models based on CO2 would have been correct, and they were not. No one can deny this, but they do anyway.

If it were, ALL climate money would go directly to deep subsidies for solar panels, and it does not. Do the math: everyone could already have them already if the money %u201Cused%u201D to date had been used for that purpose.

If it were, world governments would be building nuclear plants like crazy, and they are not. They produce no CO2 and the newer thorium-based systems are an order of magnitude safer than those built with early technology.

Climate science research goes on (http://bit.ly/SOYJpi ), but to deaf ears of those who are eager to profit from it.
