James Hansen puts an interesting spin on reports of the ninth warmest year on record

2012 was a kind of glass-half full, glass half-empty year in terms of global temperature.  

I. Climate Chief: Don't Worry, We're Still Doomed

The National Aeronautics and Space Administration's (NASA) in-depth analysis of satellite and other forms of climate data ruled the year was the ninth warmest on record.  The National Oceanic and Atmospheric Administration's (NOAA) independent analysis of ground and sea-based climate stations reported that the year was the tenth warmest on record.

The NASA report states that the average global temperature was 58.3 degrees Fahrenheit (14.6 Celsius), which is 1.0 F (0.6 C) warmer than the mid-20th century baseline, or 1.4 F (0.6 C) warmer than the earliest comprehensive observations from the 1880s.

Still, the year marks the fifth year of a relative flatline in global temperatures after a decade in which the record was regularly broken.

Global warming proponents like James Hansen, director of NASA’s Goddard Institute for Space Studies, blame this deviation from their "doomsday" calculations on a specialized cooling phenomenon called "La Nina", which lowers temperatures in the Eastern Pacific.

The climate official claims that aerosols, which reflect solar radiation, also had a cooling affect on temperatures.

Mr. Hansen argues that the public shouldn't just look at the numbers, but look at more nebulous and abstract observations, which he sees as supporting his beliefs of runaway warming.  He writes, "The observant person who is willing to look at the past over several seasons and several years, should notice that the frequency of unusual warm anomalies has increased and the extreme anomalies."

He and other global warming advocates have pointed to the summer's drought in central North America and high temperatures in the Rocky Mountains as such "extreme anomalies".  

II. A Hot Year for the U.S., Arctic, but a Cool One Elsewhere

2012, according to a separate NOAA report, was the hottest year on record for the U.S. The year did mark a new low for summer Arctic sea ice, according to NASA.  However, that could bring some benefits for mankind, such as opening up oil resources.

And temperatures for the year were actually cooler than average in several regions -- Alaska, far western Canada, central Asia, parts of the eastern and equatorial Pacific and parts of the Southern Ocean.

California meteorologist Anthony Watts, a known critic of doomsday predictions from folks like James Hansen, casts the U.S.'s record year in a different light, commenting, "If anything, U.S. temperatures are warming at a slower rate in recent decades compared to the early warming period, even with all of that lovely warm weather last year."

He points out that the recent increase (1980-2012) in U.S. surface temperatures was dwarfed by a sharp rise between 1919-1934, which was followed by a period of cooling.

In a follow-up piece, he argues the overall flatline may indicate that natural forces (including in a cooling direction) have a greater impact on global temperatures than human ones, based on his independent analysis over the last half decade.

You're basically right. There was a medieval warm period, during which crops flourished in Europe, wine was produced in Britain, and the Vikings colonized Greenland (which had forest along the southern coast at the time, hence the name) and what they called Vinland (modern Newfoundland and Labrador, which was warm enough for wine at the time, again hence the name).

But if you belong to the Church of Al Gore, warming is evil! Death to the Denialists!

Wine produced in Britain? Just like today then. Some nice, crisp whites and very good sparkling wine is produced here though I'd give the red a miss as it tends to be pretty thin and rubbish. Did you also know that the technique used to create champagne was actually first recorded in England, and not in France by Dom Perignon as some would have you believe?

Currently, the most northerly vineyard in the UK is close to York (around 54 degrees north) though in medieval times, wine was also produced around 70 miles further north in Durham. The only reason wine isn't produced that far north these days is because nobody bothers to do so!

In other words, don't believe all the memes you hear about the medieval warm period. They tend to be a load of nonsense.

The vast majority of evidence would seem to indicate that AGW exists and is here to stay. As for the alternative 'denialist' theory which seems to be that AGW is a vast conspiracy amongst thousands of corrupt poorly-paid academics looking to make a buck? Well, I know which I believe.

It will be interesting to see what happens when we get to the next solar maximum which I understand is expected in a few years. In theory, things ought to get even hotter once again. Time will tell.
