Well, which is it? Global Warming or cooling
A new study (2014) found that warming temperatures in Pacific Ocean waters off the coast of North America over the past century closely followed natural changes in the wind, not increases in greenhouse gases related to global warming.
"What we found was the somewhat surprising degree to which the winds can explain all the wiggles in the temperature curve," said lead author Jim Johnstone, who did the work while a climatologist at the Joint Institute for the Study of the Atmosphere and Ocean at the University of Washington. "So clearly, there are other factors stronger than the greenhouse forcing that is affecting those temperatures," he added. The article.
Do they really know?
Global warming/cooling is a very complex subject and there are many factors that may control our climate including; continental drift, sun spots, volcanoes, shifting poles, but also (all but forgotten) El Niño and La Niña, the Earth's axis "wobbles" and perhaps even our drift through the rotation of the entire galaxy...
News reports are saying the earth is at its warmest in 2000 years. Doesn't that simply mean it was warmer 2000 years ago? (Long before man would have had an effect!) The original source.
Here is something to think about... Only 10,000 years ago grasses covered the Sahara desert region and mammals such as lions and elephants roamed the land. What happened to that region? It is called nature! Global warming has been occurring since the end of the last ice age and will continue to occur until the next ice age begins, which may be on its way...
It is easy to pick the emotional/political cause and say man is the problem, but hold on a moment...
It is interesting to us that the warmest temperatures ever recorded have not been recent events, in fact they were in the early 1900's, locally, Nationally and Globally.
- The warmest on record for Minnesota was 114 degrees in 1917 and again in 1936.
- The lowest recorded temperature was -60 degrees in 1996. Source.
- Nationally the warmest on record was in California back in 1913.
- The lowest recorded temperature was -80 degrees Montana recently in 1971.
- Globally the warmest on record was recorded back in 1922.
- Lowest -129 in 1983. Source.
"Most of the climate community has agreed since 1988 that global mean temperatures have increased on the order of one degree Fahrenheit over the past century, having risen significantly from about 1919 to 1940, decreased between 1940 and the early '70s, increased again until the '90s, and remaining essentially flat since 1998."

Will Let cooler heads prevail: The media heat up over global warming http://www.NewsAndOpinion.com | So, "the debate is over." Time magazine says so. Last week's cover story exhorted readers to "Be Worried. Be Very Worried," and ABC News concurred in several stories. So did Montana's governor, speaking on ABC. And there was polling about global warming, gathered by Time and ABC in collaboration.
Eighty-five percent of Americans say warming is probably happening, and 62 percent say it threatens them personally. The National Academy of Sciences says the rise in the Earth's surface temperature has been about one degree Fahrenheit in the past century. Did 85 percent of Americans notice? Of course not. They got their anxiety from journalism calculated to produce it. Never mind that one degree might be the margin of error when measuring the planet's temperature. To take a person's temperature, you put a thermometer in an orifice or under an arm. Taking the temperature of our churning planet, with its tectonic plates sliding around over a molten core, involves limited precision.
Why have Americans been dilatory about becoming as worried — as very worried — as Time and ABC think proper? An article on ABC's Web site wonders ominously, "Was Confusion Over Global Warming a Con Job?"
It suggests there has been a misinformation campaign implying that scientists might not be unanimous, a campaign by — how did you guess? — big oil. And the coal industry. But speaking of coal . . .
Recently, Montana Gov. Brian Schweitzer flew with ABC's George Stephanopoulos over Glacier National Park's receding glaciers. But Schweitzer offered hope: Everyone, buy Montana coal. New technologies can, he said, burn it while removing carbon causes of global warming.
Stephanopoulos noted that such technologies are at least four years away and "all the scientists" say something must be done "right now." Schweitzer, quickly recovering from hopefulness and returning to the "be worried, be very worried" message, said "it's even more critical than that" because China and India are going to "put more carbon dioxide in the atmosphere with conventional coal-fired generators than all of the rest of the planet has during the last 150 years."
That is one reason why the Clinton administration never submitted the Kyoto accord on global warming for Senate ratification. In 1997 the Senate voted 95 to 0 that the accord would disproportionately burden America while being too permissive toward major polluters that are America's trade competitors.
While worrying about Montana's receding glaciers, Schweitzer, who is 50, should also worry about the fact that when he was 20 he was told to be worried, very worried, about global cooling. Science magazine (Dec. 10, 1976) warned of "extensive Northern Hemisphere glaciation." Science Digest (February 1973) reported that "the world's climatologists are agreed" that we must "prepare for the next ice age." The Christian Science Monitor ("Warning: Earth's Climate is Changing Faster Than Even Experts Expect," Aug. 27, 1974) reported that glaciers "have begun to advance," "growing seasons in England and Scandinavia are getting shorter" and "the North Atlantic is cooling down about as fast as an ocean can cool." Newsweek agreed ("The Cooling World," April 28, 1975) that meteorologists "are almost unanimous" that catastrophic famines might result from the global cooling that the New York Times (Sept. 14, 1975) said "may mark the return to another ice age." The Times (May 21, 1975) also said "a major cooling of the climate is widely considered inevitable" now that it is "well established" that the Northern Hemisphere's climate "has been getting cooler since about 1950."
In fact, the Earth is always experiencing either warming or cooling. But suppose the scientists and their journalistic conduits, who today say they were so spectacularly wrong so recently, are now correct. Suppose the Earth is warming and suppose the warming is caused by human activity. Are we sure there will be proportionate benefits from whatever climate change can be purchased at the cost of slowing economic growth and spending trillions? Are we sure the consequences of climate change — remember, a thick sheet of ice once covered the Midwest — must be bad? Or has the science-journalism complex decided that debate about these questions, too, is "over"?
About the mystery that vexes ABC — Why have Americans been slow to get in lock step concerning global warming? — perhaps the "problem" is not big oil or big coal, both of which have discovered there is big money to be made from tax breaks and other subsidies justified in the name of combating carbon.
Perhaps the problem is big crusading journalism.
