New research released yesterday, July 20, 2016, in the respected weekly journal of science, Nature, finds that the Antarctic Peninsula has been cooling for decades. The Antarctic Peninsula, regarded as a “global warming hot spot”, has been cooling for almost 20 years. Natural variability was responsible both for the decades-long warming since the 1950s and more recent cooling, according to the research. The research, led by John Turner from the British Antarctic Survey, said while the start of Antarctic Peninsula cooling in 1998 had coincided with the so-called “global warming hiatus”, the two were not connected. Prior to the paper’s publication, science media organizations around the world were ready with quotes from climate scientists to ensure the Turner paper was not misinterpreted.
Ms. Zharkova, a professor in the department of mathematics, physics, and electrical engineering, says this regular heartbeat of the sun is subject to predictable fluctuations of its magnetic field, and over the next few years as it enters a lull temperatures, here on earth, will plummet. This time last year Professor Zharkova announced she had discovered a key solar event which determines magnetic field variations over time. And she ‘confidently’ predicts we will be heading to another ‘Solar Grand Minima’ in solar cycle 25, beginning in 2020 and lasting until 2053.
More confirmation came out earlier this month that the Earth’s climate is naturally changing in a new study by the National Center for Atmospheric Research (NCAR). The study offers evidence that the negative phase of the Interdecadal Pacific Oscillation (IPO), which is characterized by cooler-than-average sea surface temperatures in the tropical eastern Pacific, has created favorable conditions for additional Antarctic sea ice growth since 2000.
The findings, published in the journal Nature Geoscience, may resolve a longstanding mystery: Why is Antarctic sea ice expanding when climate change is causing the world to warm? The study’s authors also suggest that sea ice may begin to shrink as the IPO switches to a positive phase.
“The climate we experience during any given decade is some combination of naturally occurring variability and the planet’s response to increasing greenhouse gases,” said NCAR scientist Gerald Meehl, lead author of the study. “It’s never all one or the other, but the combination, that is important to understand.”
Study co-authors include Julie Arblaster of NCAR and Monash University in Australia, Cecilia Bitz of the University of Washington, Christine Chung of the Australian Bureau of Meteorology, and NCAR scientist Haiyan Teng. The study was funded by the U.S. Department of Energy and by the National Science Foundation, which sponsors NCAR.
