A new map based on research recently published in Geophysical Research Letters shows that most of the northern US is increasing in susceptibility to flooding based on trends in water tables. In the South and Southeast, recent droughts have lowered water tables and stream flows, reducing their likelihood of flooding. You can read more about…

As temperatures get warmer, scientists expect that there may be impacts on soil health. To look at that, some Australian scientists tried to determine how warmer temperatures would affect soil carbon, a measure of oil health. They looked at 12 different model simulations and found that while most of them predicted a decrease in soil…

USA Today reported earlier this week that a new study of 500-year-old clams published in Nature Communications shows that the oceans are experiencing changes in ocean chemistry that have not occurred in the last 1000 years. The clam shells have growth rings similar to tree rings that can be related to climate conditions in specific…

NASA’s Scientific Visualization Studio has a couple of graphics showing changes in the frost-free regions of the US for March and April. The graphics clearly show the expansion of frost-free areas in the Midwest and Great Lakes during those months, although they have more limited value for us in the Southeast. It would have been…

In previous blog posts I have noted the unprecedented decay of sea ice over the last few years and showed a graph which indicated a rapid decline of global (combined Arctic and Antarctic) sea ice this year. Here’s an update of the chart (most recent year in red). Note that the trend towards unbelievably low…

If you were hoping for snow in last weekend’s winter storm moving through parts of the Southeast (or even if you weren’t but like weather discussions) you will be very interested in this discussion of the complex forecast surrounding the storm by Matt Daniel, UGA alum and television meteorologist at WMAZ in Macon GA. He…
