Glaciers form when millions of layers of snow compact themselves into ice. Scientists take samples from glaciers and are able to determine what happened thousands of years ago, just by examining the ice rings.

If you’re heading to San Francisco for the CyTSE conference on March 8 and 9, look for Concord Consortium staff at the following presentations: Serious Games for STEM Learning, Learning From and With Data, The Molecular Workbench, Innovative Technology in Science Inquiry, and Inquiry in the Digital Age – Enhancing Science Learning using Computer Models.
The Concord Consortium will be attending and presenting at the NSTA conference in March 2011. We look forward to seeing you at our sessions. Add the following sessions to your conference schedule.
A new study from the University of Colorado suggests that 66% of Earth’s permafrost could disappear by the year 2200. And this could be really bad for Earth’s temperature. If the temperature increases, the permafrost melts. Simple enough, right? But it’s slightly more complicated. Trapped in the permafrost is lots and lots of carbon–in the […]
A new study from the University of Washington suggests that Earth’s temperature will keep increasing, even if all greenhouse gas emissions were stopped right now. Why? Because greenhouse gases will last longer in the atmosphere than particulate matter (aerosols) that reflect the sun’s light. So, the solar radiation coming in will increase and the heat […]
The Concord Consortium’s Paul Horwitz and Evolution Readiness advisory board member Louise Mead of the BEACON Center for the Study of Evolution in Action discuss “the evolution of teaching evolution“ in a February 7 article originally published in the Hechinger Report.
The following are two Energy2D simulations that compare convection and conduction, which should run within this page if you have installed Java and Java applets are enabled with your browser. The first one shows the case of natural convection. The seco…
“Within the next 6 to 12 months, I suspect we’ll be able to detect and verify and announce planets that at least have the size of our own Earth.” –Dr. Geoffrey Marcy, University of California Berkeley “This changes our understanding of our role in the universe. We, in some sense, are not alone in terms […]
It seems counter-intuitive, but it seems that warmer summers actually slow the flow of Greenland’s ice sheets. A new study, published yesterday in Nature, explains how increased melting in warmer years causes the internal drainage system of the ice sheet to change, slowing the glacier’s flow towards the ocean. Normally, the melt-water finds its way […]
Warm millennium, that is. And Southern Hemisphere, that is. New research suggests that Earth will continue to warm into the year 3000, even if human-caused carbon dioxide emissions stop right now. According to their models, scientists predict that the Northern Hemisphere will fare much better, with the warming trend reversing within the millennium. This is […]
