All data sets support the warming since the 1970's. That is a fact...Learn to accept it.
You need to go back to 1850 Matthew. And, most of the warming occurred over 50 years ago. No matter what the data manipulators claim the 1930's were far warmer than the present day with far more days over the 100 degree mark than any decade since.
Like hell. Only in the US was the '30's that warm. You continue to by a lying fuck. By your thinking, January and February were record cold months worldwide because the Eastern US was cold.
1934 is the hottest year on record
Climate Myth...
1934 - hottest year on record
Steve McIntyre noticed a strange discontinuity in US temperature data, occurring around January 2000. McIntyre notified NASA which acknowledged the problem as an 'oversight' that would be fixed in the next data refresh. As a result, "The warmest year on US record is now 1934. 1998 (long trumpeted by the media as record-breaking) moves to second place." (
Daily Tech).
The year 1934 was a very hot year in the United States, ranking fourth behind 2012, 2006, and 1998. However, global warming takes into account temperatures over the entire planet. The U.S.'s land area accounts for only 2% of the earth's total surface area. Despite the U.S. heat in 1934, the year was not so hot over the rest of the planet, and is barely holding onto a place in the hottest 50 years in the global rankings (today it ranks 49th).
Climate change skeptics like to point to 1934 in the U.S. as proof that recent hot years are not unusual. However, this is another example of "cherry-picking" a single fact that supports a claim, while ignoring the rest of the data. Globally, the ten hottest years on record have all occurred since 1998, with 2005 and 2010 as the hottest.
The fact that there were hot years in some parts of the world in the past is not an argument against climate change. There will always be regional temperature variations as well as variations from year to year. These happened in the past, and they will continue. The problem with climate change is that on average, when looking at the entire world, the long term trend shows an unmistakable increase in
global surface temperatures, in a way that is likely to dramatically alter the planet.
