ice core, definition of

Carbon is the chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. There are three naturally occurring isotopes, with 12C and 13C being stable, while 14C is radioactive, decaying with a half-life of about 5730 years. Carbon is one of the few elements known since antiquity. The name "carbon" comes from Latin language carbo, coal.

• Oldest ice core ever dated reveals hidden clues to ancient Earth's atmosphere
  Ice cores hold secrets of what our planet was like millions of years ago, in bubbles preserving greenhouse gases from that time. A Princeton University-led team just revealed the date of ice from the oldest ice core we've ever dated, and it's 2.7 million...
• The Warmer The Icier
  Guest Post by Willis Eschenbach A WUWT commenter emailed me with a curious claim. I have described various emergent phenomena that regulate the surface temperature. These operate on time scales ranging from minutes to hours (e.g. dust devils, thunderstorms)...
• New ice core record shows climate variability in West Antarctica
  Similar warming and cooling trends occurred in the mid-nineteenth and eighteenth centuries From AGU highlights: A 308-year ice core record provides new data on climate variability in coastal West Antarctica and shows that a clear warming trend has occurred...
• Ancient Antarctic Ice Could Reveal Clues to Earth’s Climate 1.5 Million Years Ago
   Image © Shutterstock Swiss scientists from the University of Bern are hoping that a 3 km long cross-section of Antarctic ice could reveal new information about climate change throughout the Earth’s history...
• The oldest ice core – Finding a 1.5 million-year record of Earth’s climate
  How far into the past can ice-core records go? Scientists have now identified regions in Antarctica they say could store information about Earth’s climate and greenhouse gases extending as far back as 1.5 million years, almost twice as old as …...
• Recent climate, glacier changes in Antarctica at the ‘upper bound’ of normal
  From the University of Washington some walkback? In the last few decades, glaciers at the edge of the icy continent of Antarctica have been thinning, and research has shown the rate of thinning has accelerated and contributed significantly to sea …...
• Will Lonnie Thompson archive THIS new ice core data?
  From the Ohio State University , taken with a grain of salt since Dr. Thompson and his wife Ellen are serial non archivers of ice core data (even when asked for it), which prevents other scientists from checking their work. … Continue reading →
• AGW Proponents Fight Rearguard Action As Political Climate Science Fails
  Guest post by Dr. Tim Ball Proponents of the anthropogenic global warming (AGW) hypothesis are cornered. They made a political choice to prove rather than disprove the hypothesis, as the scientific method requires. It failed, as IPCC projections (range...
• First complete ice core record of last interglacial period shows the climate of Greenland to be significantly warmer than today
  Study: ‘ Greenland ice sheet is not as sensitive to temperature increases and to ice melting and running out to sea in warm climate periods ‘. From the University of Copenhagen Greenland ice cores reveal warm climate of the past … Continue...
• Does The Effect From The Cause Affect The Cause?
  Guest Post by Willis Eschenbach There’s been a recent paper claiming a long-term correlation between CO2 and sea level, discussed here at WUWT. The paper implies that CO2 controls temperature and thus indirectly sea level. I thought I might follow...
