Scientists say droughts and wet periods come and go between ice ages. To understand and predict long-term climate changes, Northern Arizona University assistant research professor Nick McKay examines sediment samples from Arctic lakes.

Researchers from Northern Arizona University traveled to Alaska and Switzerland, among other places, in a quest to learn how the Earth’s climate has changed over time. It’s the subject of a documentary called "Taking Earth’s Temperature: Delving Into Climate’s Past."

The key to understanding recent climate changes could be at the bottom of Arctic lakes. That's what Darrell Kaufman believes. He's a paleoclimatologist at Northern Arizona University and studies core sediment samples of Arctic mud to get a glimpse of thousands of years of environmental changes.

September 24, 2014- NAZ Today looks into NAU's Idea Lab and their recently produced film about climate change . . .

The film will be screened Friday, September 26 at 6:30 p.m. at Cline Library. The film was also recently aired on Phoenix's KAET Channel 8.

As the Intergovernmental Panel on Climate Change releases Vol. 1 of its fifth assessment report, the results of published investigations by several Northern Arizona University researchers are receiving renewed international attention.

The IPCC represents the world’s scientific community by periodically reporting on the state of knowledge about climate change. The organization follows an extensive peer-review process to independently assess all published information and to summarize the most relevant advances in climate science.

A Thousand Invisible Cords will be screened at the 2013 Flagstaff Festival of Science on Thursday evening, September 26, at 6:30 pm in NAU's Cline Library Auditorium. NAU Regents’ Professor Tom Whitham (Department of Biological Sciences), who is one of the featured scientists in the film, will be master of ceremonies for the screening. The event is free and open to the public.

Next month, a scientific committee sponsored by the United Nations will put out its latest assessment of climate change. The report is expected to underscore yet again that climate change is a serious problem and human beings are largely responsible.

The (IPCC) represents a consensus view of hundreds of scientists from around the world. The effort shared the 2009 Nobel Peace Prize with Al Gore.

On its first day of broadcasting, Al Jazeera America devoted 30 minutes to climate change—more time than top shows on CNN and Fox News have given to this issue in the past four-and-a-half months, combined. In fact, the full half-hour (24 minutes, plus commercials) of broadcast of Inside Story was equal to about half of the coverage climate change received in 2012 from the nightly news on ABC, CBS, NBC, and Fox, combined.

While the Obama administration presses forward with plans to deal with climate change, Congress remains steadfast against taking action. It's not easy to find a scientist who will agree with that point of view. But Republicans have found an ally in a climate scientist by the name of Judith Curry.

"The main conclusion of the study is that the most coherent feature in nearly all of the regional temperature reconstructions is a long-term cooling trend, which ended late in the 19th century, and which was followed by a warming trend in the 20th [century]."

From: Major PAGES 2k Network Paper Confirms the Hockey Stick

"... two main results are a confirmation that current global surface temperatures are hotter than at any time in the past 1,400 years (the general 'hockey stick' shape...), and that while the Medieval Warm Period (MWP) and Little Ice Age (LIA) are clearly visible events in their reconstruction, they were not globally synchronized events.

From the ABC Science's article "Late 20th century hottest in over 1000 years"

"Average temperatures around the world in the last thirty years of the 20th century were higher than any other time in nearly 1400 years.

That's the conclusion of the first climate reconstruction to examine global climate change from a regional perspective by an international network of climatologists known as the PAGES 2k network."
