A new study by Neil Pederson and four co-authors presents a 1,112-year tree-ring-based self-calibrating Palmer Drought Severity Index (scPDSI) reconstruction for the Central Mongolian warm-season, using 107 living and dead Siberian pines growing on the Khorga lava flow. The reconstruction...

In the provocative new book “Supply Shock,” ecological economist Brian Czech argues that perpetual economic growth is a doomed policy and that the world must transition to a steady state economy to curb over-exploitation of natural resources and climate change. Climate change is driven by...

A presumed benefit of global warming is the assumption that warmer winter temperatures might decrease excessive winter deaths (EWDs) common in temperate climates. EWDs are defined as the difference between the number of deaths in a region during winter months (December – March) and the average of...

After much of the U.S. experienced an unusually long and cold winter, many ask whether climate change is still happening.  There has, in fact, been little change in global mean annual temperature since the early 2000s leaving scientists struggling to figure out where the heat associated with...

Recently analyzed ice core data from West Antarctica confirms warming since 1957, but shows two other warming episodes over the past three centuries suggesting that anthropogenic influences are within the range of natural variation of climate there. Elizabeth Thomas and collaborators’ study focused...

Earth’s surface shows large zonal asymmetries, i.e., surface properties vary greatly in longitude, and these asymmetries greatly impact the dynamics of the overlying atmosphere. These asymmetries can be broadly characterized by whether they primarily affect the atmosphere through mechanical or...

A recent study published in Global and Planetary Change demonstrates cost-saving opportunities in the otherwise computationally expensive process of high-resolution climate modeling.  General Circulation Models (GCMs, occasionally also referred to as ‘global climate models’) are extremely useful...
