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.

Dendrochronology's "Divergence Problem" Explained?

A new study by Alexander Stine and Peter Huybers offers strong evidence that reduced light availability (“global dimming”) explains the apparent lack of tree-ring evidence in many Arctic regions for the recent warming observed in instrumental records there. Dendroclimatology uses measurements of the yearly growth width and density of tree rings to reconstruct changes in past climate. The …

Studying the ecological roles of top predators and the impacts of climate change on predator-prey interactions and ecosystem dynamics

I study the effects of climate change on animals, the interactions they have with each other and plants, and the cascading impacts of climate change on humans and how we live. This research is important because the climate is changing rapidly and we need to understand how ecosystems will respond so that we can adapt to the new realities of a warming world.

Belowground biotic interactions and how they respond to, and influence climate change via climate-ecosystem carbon feedbacks.

My research interests include soil, ecosystem and climate change ecology. Specifically, my work focuses on biotic interactions and how they respond to, and influence climate change via climate-ecosystem carbon feedbacks. My PhD work, conducted at Cardiff University, centered on the topic of soil biodiversity. This work advanced our theoretical and mechanistic understanding of how top-down processes control soil biodiversity and nutrient cycling.

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…
