2005 Will Probably be Warmest on Record 698
Nilmat writes "A Washington Post Article notes that 2005 will probably have the highest mean global temperature of any year since the advent of systematic temperature records. At the moment, the mean temperature is about 0.75 degrees C above the global mean from 1950 to 1990, approximately .04 degrees higher than 1998, the year of the previous record. Only something dramatic, such as a major volcanic eruption, could cause enough cooling to miss setting a new record."

Suppose the temperate band moves 5 degrees towards the poles, what happens? Would there be the same amount of arable land, or more, or less? Hint: the world is round like a ball. The further north you go from the equator, the less the diameter is, and consequently the less surface there is per degree. Furthermore, most of the current temperate zone was under broadleaved woodland for thousands of years before the coming of agriculture, and we're still using the depth of fertile soil laid down in thousands of years of leaf-fall. But the current tundras have been tundras for thousands of years, and don't have any great depth of soil fertility. So it does matter if the temperate belt shifts five degrees towards the poles.

Only at a local level, these figures are global.
so how can anyone predict the weather for the next 2 1/2 months based on historical records and in face of supposedly dramatic climate changes...
The figures are global and also average, so it is possible to calculate ahead how cold things would have to get to reduce the "total" temperature and say whether or not that is likely. If the world record for an average score at some game was, say 9.5 over a 10 game season, and after 8 games a player had scored a total of 90 points, you'd feel pretty confident in saying that a record was coming, regardless of the fact that the last two games haven't been played.

Recent demonstration of global warming (Score:4, Informative)
Fact: Accurate satellite, balloon and mountain top observations made over the last three decades have not shown any significant change in the long term rate of increase in global temperatures.
No, that's not true at all. All terrestrial measurements have shown a steady increase - the satellite measurements were the exceptions, and showed a much slower increase in temperature.
Until last year, fossil fuel advocates pointed to the satellite measurements as refutation of the warming trend. Then, a bunch of clever guys realised that the problem was that the satellite measurements were taking an average of a rapidly heating troposphere (where we live) and a cooler upper section of the atmosphere.
There's a great discussion of this in the rather frightening book The Weather Makers by Australian scientist Tim Flannery, which is due for release in the US about now.

"Myth 4" is another mixture of truth and falsehood. Yes, water vapour is a greenhouse gas. However, relative humidity is more or less a constant in the atmosphere. Thus, the amount of water vapour (absolute humidity) is driven by the temperature. In this way water vapour increases the effect of any other heating - its an amplifier, but not a cause of global warming.
If you look over the site, you find more gems. "Myth 6", for example, not-cites the 1996 IPCC report, totally ignoring the current (2001) and upcoming reports.
Wikipedia has a reasonable good set of articles on global warming [wikipedia.org].

Thus inferring global warming from a 3 Martian year regional trend is unwarranted. The observed regional changes in south polar ice cover are almost certainly due to a regional climate transition, not a global phenomenon, and are demonstrably unrelated to external forcing. There is a slight irony in people rushing to claim that the glacier changes on Mars are a sure sign of global warming, while not being swayed by the much more persuasive analogous phenomena here on Earth...

again, reading the graph, from 1880 - 1910, there was a warming period that was even more significant than the one currently observed. Why?
From 1910 - 1940, there was a very significant decrease in temperateure. Why?
So, from 1880 - 1910 I'm sure everyone was afraid of the next heat wave
and from 1910 - 1940, there was an ice age headed our way.
Interesting that this graph shows a classic bell shaped curve that we all learned to love in our college statistics classes. It is safe to predict regular variations that follow the same pattern. Therefore, I predict in 20 - 50 years (a very short time span in the grand scheme of things), that a cool down will occur.

Apparently, very many times. Key points: It wasn't 1995, it was 1988, and Hansen wasn't off by 300%, he was frickin' on the money.
Also, remember that Arrhenius predicted [columbia.edu] anthropogenic CO2 global warming over 100 years ago. The basic premise- more atmospheric CO2 means more trapped heat- is well-understood and not controversial. The open question is the strength of the climate's negative feedback cycles.
