Global Warming TRUE - US warmest in at least 400 years |

Earth warmest in at least 400 years, panel finds
National Research Council report focuses on 'hockey stick' data
Intergovernmental Panel on Climate Change

Panel on Climate Change, has been dubbed the "hockey stick" chart due to
its shape.
WASHINGTON - Weighing in on the highest profile debate about global
warming, the nation's premier science policy body on Thursday voiced a
"high level of confidence" that Earth is the hottest it has been in at
least 400 years, and possibly even the last 2,000 years.
A panel convened by the National Research Council reached that
conclusion in a broad review of scientific studies, reporting that the
evidence indicates “recent warmth is unprecedented for at least the last
400 years.”
The panel of top climate scientists told lawmakers that the Earth is
running a fever and that “human activities are responsible for much of
the recent warming.” Their 155-page report said average global surface
temperatures in the Northern Hemisphere rose about 1 degree F during the
20th century.
The report was requested last November by the chairman of the House
Science Committee, Rep. Sherwood Boehlert, R-N.Y., to survey what
science says about climate change over the last 2,000 years.
Last year, when the House Energy and Commerce Committee chairman, Rep.
Joe Barton, R-Texas, launched an investigation of three climate
scientists, Boehlert said Barton should try to learn from scientists,
not intimidate them.
The Bush administration also has maintained that not enough is known
about the threat to warrant new emission controls that the White House
says would have cost 5 million Americans their jobs.
Boehlert said Thursday the report shows the value of having scientists
advise Congress. “There is nothing in this report that should raise any
doubts about the broad scientific consensus on global climate change,”
he said.
Many scientists tie warming temperatures to rising emissions of certain
gases like carbon dioxide. While essential to survival, carbon dioxide
has seen a spike as fossil fuels are burned by cars and factories,
leading to concerns that it and other gases are exacerbating the
greenhouse effect that keeps Earth inhabitable.
“The numerous indications that recent warmth is unprecedented for at
least the last 400 years and potentially the last several millennia, in
combination with estimates of external climate forcing variations over
the same period, supports the conclusion that human activities are
responsible for much of the recent warming,” the panel wrote.
The report focused on research data criticized by warming skeptics and
which was published in 2001 by the Intergovernmental Panel on Climate
Change, a United Nations body that has led international warming research.
Climate scientists Michael Mann, Raymond Bradley and Malcolm Hughes had
prepared the research, concluding that the Northern Hemisphere was the
warmest it has been in 1,000 years. Their research included a graphic
dubbed the “hockey stick” because of the way the temperature data looked
when presented over time — stability followed by a sharp curve upwards
over the last 140 years.

Now THAT raises a red flag! We were in the 'Little Ice Age" in 1600
A.D. That's like saying, "the earth has been in a definite,
significate warming trend since January 1st of this year"- A. McIntire
" the panel wrote. It said the "recent warmth
is unprecedented for at least the last 400 years and potentially the last
several millennia," though it was relatively warm around the year 1000
followed by a "Little Ice Age" from about 1500 to 1850.

See, they implicitly agree with me- A. McIntire
