Study Finds Recent Global Warming Unprecedented In 1,300 Years!

Study Finds Recent Global Warming Unprecedented In 1,300 Years!

WASHINGTON — A new scientific study adds evidence that temperatures in the Northern Hemisphere fluctuated a bit over time, but that the sharp increase during the past few decades is bigger than anything in at least 1,300 years.

The report was published Tuesday in the Proceedings of the National Academy of Sciences. Its conclusion is that temperature increased and decreased a little over the centuries, but the fluctuations were small enough that the line was roughly flat, like the shaft of a horizontal hockey stick. Then, from about 1980 to now, temperature increased sharply, more than any increase before — like the blade of the hockey stick.

I can't keep up with this week to week global warming consensus...One week, one group of scientists say it is astronomical, the next week some opposing group says it's all hooey, then the following week, something such as this...

Hard to know what to believe anymore.

They took data from other natural sources of clues about past climate — corals, ice cores and lake and cave sediments.

"We found we got more or less the same answer," Mann said. The recent temperature increase is an anomaly over 1,300 years without using tree rings, and for 1,700 years if the tree-ring data are used, the study found.

Why do these articles always seem to contradict themselves!

Here in the article they are doing there "fear mongering".

Study finds recent global warming unprecedented in 1,300 years

Then, from about 1980 to now, temperature increased sharply, more than any increase before — like the blade of the hockey stick.

The words, "more than any increase before" to me would mean it never happened before! Ever!

But the title of the article says,

"Study Finds Recent Global Warming Unprecedented In 1,300 Years!"

And the study says this:

The recent temperature increase is an anomaly over 1,300 years without using tree rings, and for 1,700 years if the tree-ring data are used, the study found.

So what they are REALLY saying is that it only hasn't happened in the last 1,300 to 1,700 years!

They have no data if this temperature fluctuation happened earlier than 1,300 to 1,700 years ago.

But they've just GOT to get that fear mongering, doomsday line in their!

more than any increase before -

They really mean in the last 1,300 to 1,700 years.

It really all depends on the scientists writing them.
If they are on someones payroll or working just for science itself.
I would have to believe that anything that comes out of Washington would tend to be a little biased.
