Climate Change

formerly “Climate Science” this has been updated in recognition of the fact that ALL of our articles, events, etc. involve climate sciience.  ”Climate change” is intended to suggest changing elements of the climate: e.g., shifts in global oceanic and atmospheric circulation and ensuing changes to temperature, precipitation, groundwater levels, saltwater intrusion.

Wind and Topographic Irregularities Influence Antarctic Melting

Loss of mass from ice sheets contributes to rising sea level. To understand the contributions of ice-sheets to sea level rise we must understand the spatial and temporal variability of ocean-driven melting, which has accelerated over recent decades.  Dutrieux and colleagues used observations and results from numerical modeling to show the case of Pine Island Glacier in the Amundsen Sea in west…

For Ecologists, Is Climate Change Research Sufficiently Complex?

Climate change will alter myriad natural processes as precipitation patterns shift and oceanic and atmospheric temperatures and CO2 concentrations rise. Modern ecology and environmental science has already examined the potential effects of climate change on species and ecosystems, allowing us to elucidate the mechanisms and pathways through which it may operate (Tylianakis et al. 2008)…

Climate Change Impacts Antarctica's Ross Sea

The Ross Sea, Antarctica’s most pristine region, is experiencing anomalously marked increase in sea ice concentration. Future changes in atmospheric temperatures and wind speeds, however, will likely produce a noticeably different environment. Smith et al. examines the effect of projected changes in atmospheric temperatures and winds on aspects of ocean circulation and its implications for primary…

After a Hard Winter, Scientists Explain "Where Has All the Warming Gone?"

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 continuing greenhouse gas emissions has gone.  In a recent paper…

Down-scaling Climate Models Without Up-scaling Costs

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 tools used to understand how our climate system works.  The models use mathematical equations to describe the physics of the oceans and atmosphere.  These equations quantify, for example, how hot air tends to rise (the reason hot air balloons fly) and how the wind flows from high-pressure areas to l

Water-related Disease and Climate

Human-induced climate change is altering precipitation patterns in most parts of the world (Stocker et al., 2013). In the future, climate change will likely exacerbate droughts (Trenberth et al., 2014; Dai, 2012) and drastically increase the likelihood of floods throughout many parts of South America, Africa and southern Asia (Hirabayashi  et al., 2013) …
