Research Into Oaks Helps Us Understand Climate Change
August 2, 2012 — Biologists are tracking the evolution of the live oaks of eastern North America, seeking to understand how the trees adapted to climate change during glacial ... > full story -
Tropical Climate in the Antarctic: Palm Trees Once Thrived on Today’s Icy Coasts 52 Million Years Ago
August 1, 2012 — Given the predicted rise in global temperatures in the coming decades, climate scientists are particularly interested in warm periods that occurred in the geological past. Knowledge of past episodes ... > full story -
Atmospheric CO2 Drove Climate Change During Longest Interglacial
July 31, 2012 — Known as the marine isotope stage 11 (MIS 11), the interglacial period centered around 400,000 years ago was the longest and possibly the warmest interglacial in the past 0.5 million years. Because ... > full story -
Cooling, Not Population Loss, Led to Fewer Fires After 1500 in New World
July 30, 2012 — After Columbus’ voyage, burning of New World forests and fields diminished significantly – a phenomenon some have attributed to decimation of native populations. But a new study suggests ... > full story -
Scientists Connect Seawater Chemistry With Ancient Climate Change and Evolution
July 19, 2012 — Humans get most of the blame for climate change with little attention paid to the contribution of other natural forces. Now, scientists are shedding light on one potential cause of the cooling trend ... > full storyMore: -
Trigger for Past Rapid Sea Level Rise Discovered
July 11, 2012 — The cause of rapid sea level rise in the past has been found by scientists using climate and ice sheet models. The process, named 'saddle-collapse', was found to be the cause of two rapid sea level ... > full story -

July 10, 2012 — Switzerland’s highest peaks in the geologically young central Alps have been this high for quite some time, as a new study shows. 15 million years ago Europe’s own mountain range was at ... > full story -
Climate in Northern Europe Reconstructed for the Past 2,000 Years: Cooling Trend Calculated Precisely for the First Time
July 9, 2012 — Scientists have published a reconstruction of the climate in northern Europe over the last 2,000 years based on the information provided by tree-rings. Researchers used tree-ring density measurements ... > full story -
Natural Climate Shifts Drove Coral Reefs to a Total Ecosystem Collapse Lasting 2,500 Years
July 5, 2012 — A new article shows how natural climatic shifts stopped reef growth in the eastern Pacific for 2,500 years. The reef shutdown, which began 4,000 years ago, corresponds to a period of dramatic swings ... > full story -
