Sea-Level Rise & the State of Sinking: A Brief Discussion of Land Subsidence Factors in the US

What’s scarier than sea level rise? How about sea level rise in a sinking city? Land levels are slowly lowering due to a combination of natural and man-made processes across many US cities. This sinking is known as land subsidence. Read on to learn how land subsidence contributes to sea level rise conflicts across the United States.

Flame retardant sharks?

Flame retardants are found everywhere from your house to your car. Unfortunately, these chemicals can accumulate in the environment, including the ocean. Once in the ocean, flame retardants can make their way into marine organisms. The researchers in this study wanted to determine if flame retardants are transferred from mothers to offspring in sharks.

Burning Desire to Forage

During the fall of 2018, California had some of the worst and deadliest fires to date, with devastating costs to human communities. Communities of plants and animals are also greatly impacted by fires. But how does wildlife respond to wildfires? Burns alter the environment and open up new habitats allowing smaller shrubs to recolonize in areas that were dominated by tall trees. A recent study in Oregon suggests that elk utilize a wide array of habitats and that burned forests are critical areas for food for many herbivores.

How can we help salt marshes recover after an oil spill?

Salt marshes impacted by oil spills (like Deepwater Horizon) often experience vegetation diebacks and a loss of ecosystem function. Researchers recently found that re-establishing the dominant salt marsh vegetation, Spartina alterniflora, is critical to ensure and enhance the presence of other marsh animals. Unexpectedly, the addition of fertilizer had little to no effect on the recolonization of salt marsh critters.

Bacteria, Viruses and Carbon: how microorganisms in arctic soils can alter our climate

Wetland soils store 20-30% of global soil carbon, that carbon is mostly controlled by bacterial populations. Arctic wetland soils store twice as much carbon as the atmosphere, but are frozen year round as permafrost which limits microbial activity. We try to predict what will happen with microbial communities and soils when temperatures continue to warm, but we’re finding out it’s more than just bacteria that are driving arctic carbon cycles.

Climate change could make your beer dear

Apart from being popular beverages in the world, do you know what the common link between beer and coffee is? Both may be affected by climate change. While we already know that climate change will impact coffee, a new study published in Nature Plants has established that beer is also under threat. Rising temperature and drought due to climate change can hit the beer supply hard all over the world and make beer more expensive.

Desalination: As If Corals Didn’t Have Enough to Worry About Already

Clean, safe drinking water is a basic human need. However, for many areas around the globe, freshwater is becoming scarce. Desalination is increasingly used to provide drinking water in some coastal regions, but the waste products – brine and antiscalants – are discharged back into the ocean with unknown consequences. A recent study by Karen Lykkebo Petersen (University of California Santa Cruz) and colleagues sought to simulate happens to coral reefs as they are increasingly exposed to desalination discharge.
