SUMMARY: Did 2005 feel like a scorcher? Well, you're right. According to NASA researchers, 2005 was the warmest year for planet Earth in more than a century. Scientists have used weather stations on land, ships on the ocean, and satellite measurements from space to keep track of average global temperatures. Over the last 100 years, temperatures have risen on average by 0.8° C or about 1.4° F. And the five warmest years were 2005, then 1998, 2002, 2003 and 2004.

There seems to be little doubt that global temperatures are rising gradually. What is not clear is to what extent this results from human activity as opposed to a continuing recovery from the last Ice Age.
That there is a human contribution seems certain. That we should try to reduce it is equally certain, but I am not convinced that we are the whole cause.

A century ago is was as hot, so why did it dip and what made it so warm 100 years ago or so.?

Somehow I doubt that in the late 1800's anyone possessed the necessary technology to measure the average temperature of the entire world... if indeed they did, please tell me who :)

Instrumental data describing large-scale surface temperature changes are only available for roughly the past 150 years. Estimates of surface temperature changes further back in time must therefore make use of the few long available instrumental records or historical documents and natural archives or 'climate proxy' indicators, such as tree rings, corals, ice cores and lake sediments, and historical documents to reconstruct patterns of past surface temperature change.

No it wasn't.
We have reliable (actually measured) data for about a century (more in a lot of countries, less in remote areas like Antarctica), and 2005 was the warmest of those years. This does not mean that it was equally hot or hotter 101 years ago.
As we don't have relatively complete year-by-year measurements from over a centruy ago, we can't with certainty say that there hasn't been a single year that was hotter over the last few thousand years. However, as has been reported in the mainstream press (http://www.cnn.com/2006/WEATHER/01/24/hot.year.ap/index.html) (but can also be found in more scientific publications), the current climate, i.e. the average of the last thirty years, is about the warmest it has been for (at least) 10,000 years.
This and much more about global warming has been (heatedly, haha) debated in this thread (http://www.bautforum.com/showthread.php?p=665985#post665985) and a lot of other ones.

I am enjoying this unseasonably warm temperatures.

I just hope my grandchildren will live to make children of their own.

One of the local weathermen brought up an interesting statistic a couple of weeks ago...I'll recount it from memory:

--Two-thirds of all January record lows in SA took place before 1945, and only one-third after.

--There hasn't been a new record January low for any day since 1985, which he said was statistically bizarre; normally we'd expect a new January low every four or five years.

I know that this January will probably go down as one of the warmest on record...several days have been practically balmy.

This has been the mildest January I can remember for the Maryland/Virginia area.

I wore a hawiian shirt yesterday without a jacket. That is abby normal in my neck of the woods.

Models of global warming predict that some regions get colder and some warmer (because of changes in ocean currents and prevailing winds, for example) even as the over-all globe gets warmer. I recall one prediction for the midwest US is more extreme seasons (colder winters, warmer summers), but overall warmer.

I'm not saying that snow in southern Europe was caused by global warming, but it is not inconsistent.

You can check the New York Times where NASA climate scientist James Hansen claims NASA is trying to prevent him from speaking about global warming, and this statement has generated a reaction in Congress,
http://www.nytimes.com/2006/01/29/science/earth/29climate.html?_r=1&oref=slogin
this issue might soon come up the next time Griffin appears before Boehlert's committee but recently ne spokesman for a senator accused Hansen of pushing political views
however Dr. Hansen has responded by saying that nothing in 30 years equaled the push made since early December to keep him from publicly discussing what he says are clear-cut dangers from further delay in curbing carbon dioxide.
