Why do they say there is global warming, when the warmest years were during the "dust bowl years of the 30's?

Question

I'm 53 years old I have not noticed any change in the average climate in the past half century. Do you think that it is possible that "the emperor has no clothes" and everyone is just afraid to say that Al Gore is wrong because they want to be PC?

Answer 1

Your question and grammar are similar to another denier on this board. Bringing up the 30's as the warmest years and speaking of the emperors clothes. I can't pin you down yet, but I'll figure it out. As anyone who has shown the slightest interest in fact would know, 1934 was the warmest year in the US, not the globe. And we are debating GLOBAL warming, aren't we?

Does it really matter what you have noticed? After all, you may not be the most perceptive person on the planet, for all we know. It's better you provide respected sources to back up your claims. People will be more inclined to take into consideration your views.

Answer 2

People who say this are IGNORANT of the issue. Global warming is global. The warmest temperatures globally have all been within the past decade.

Some of the warmest years for the continental US were during the 1930's. But because the continental US makes up less than 2% of Earth surface area, this information has limited relevance.

Answer 3

The discussion of global warming is not so much about the temperature of any given year, it is about the rise of greenhouse gases in the atmosphere. The amount of carbon dioxide, a major greenhouse gas, has risen precipitiously in the past couple of decades. This has a bearing on climate trends in the long run. There may be anomalous years here and there, but as the co2 rises, there will be more high-temperature years.

Answer 4

Global temperatures left the 1930s behind about 25 years ago:

So someone has misinformed you.  Fox News perhaps?

At Fox News, a Pundit for Hire

"Objective viewers long ago realized that Fox News has a political agenda. But, when a pundit promotes this agenda while on the take from corporations that benefit from it, then Fox News has gone one disturbing step further"

Here's a detailed analysis of the effects of climate change on agriculture, water supplies and quality, and electrical demand appears in this report to Congress:

The Potential Effects of Global Climate Change on the United States

http://www.epa.gov/climatechange/effects...

"The effects of a warmer climate alone would generally reduce wheat and corn yields. Yield changes range from + 15 to -90%."

"Dryland farmers in the Great Plains are particularly vulnerable to climate variability. The Great Plains States of Nebraska, Kansas, Oklahoma, and Texas were the hardest hit during the Dust Bowl of the 1930s (Worster, 1979; Hurt, 1981). Yields of wheat and corn dropped as much as 50% below normal, causing the failure of about 200,000 farms and migration of more than 300,000 people from the region."

The science of global warming has nothing whatsoever to do with Al Gore.  He's just a guy who made a movie about it.

The recent count of pro vs. con positions by actual peer-reviewed scientific papers is summarixed here:

http://norvig.com/oreskes.html

The consensus was quantified in a Science study by Prof. Naomi Oreskes (Dec. 2004) in which she surveyed 928 scientific journal articles that matched the search [global climate change] at the ISI Web of Science. Of these, according to Oreskes, 75% agreed with the consensus view (either implicitly or explicitly), 25% took no stand one way or the other, and none rejected the consensus.

So global warming is well documented as happening.  The Dust Bowl is no consolation, it is an example of things to come.  For those of us the U.S. the plummet in the dollar and the rise in oil prices won't help, and our food costs will continue to rise sharply.

Answer 5

Because they weren't.  NASA data.

http://data.giss.nasa.gov/gistemp/2007/

I simply don't understand the obsession with Gore.  These people don't say global warming is real, and mostly caused by us, because of Gore.

The National Academy of Sciences, the American Association for the Advancement of Science, the American Institute of Physics, the American Chemical Society, the American Geophysical Union, the American Meteorological Association, etc.

They say it because it's been scientifically proven, with data.

Answer 6

You are confusing the US (which is about 2% of the earths surface) with the entire planet.  The key word is "global".  And the global average temperature has most definitely been rising over the past 50 years.

Answer 7

Because people are doing this for financial and/or political gain. Water is twice as strong as a green house gas than CO2, and it's present at a concentration 100's of times that of CO2. I challenge anyone to find actual scientific evidence of CO2 inducing global warming. No, the main stream media is not a viable source....try finding something in a peer-reviewed journal, such as Science or Nature.

Answer 8

The sun's corona fluctuates between 1 and 3 million degrees celsius.  and the earth is not perfectly round, nor does it rotate in a perfect axis.  100 years of data is not enough.

but if it helps people be more conservative with energy, and helps spur people's imagination to build a more efficient/environment friendly ways of energy use, then its not really doing any harm.  human population isnt shrinking.  if we wait till its too late to move from oil to other forms of energy, there is going to be a big problem in society.

Answer 9

They weren't.  The hottest year in the US was 1934, but on a global scale, that was a very average year.  The hottest years have all happened in the past decade, as you can see here:

http://data.giss.nasa.gov/gistemp/graphs...

Al Gore is just the messenger.  It's the scientists who are warning us about global warming.

Answer 10

You are looking at the temperature data for the US and north America.  The US and north America is not the globe.  This is why it is called global warming and not US warming.
