Improvements in Water Quality Offset Climate Debt in UK Rivers

By analyzing over 20,000 samples of aquatic macroinvertebrates, researchers were able to show that shifts in macroinvertebrate communities corresponded to improvements in water quality from 1991 to 2011. The improvements in water quality have created a “credit” that could have offset the climate debt created by rising temperatures. Local improvements can potentially offset global climate impacts, but for how long can this trend continue?

Why coastal flood maps are wrong: the tale of compound hazards

Coastal flooding is expected to increase in frequency due to future sea level rise and more extreme weather, but most coastal flood hazards maps do not portray the increase risk. We dive deeper into how these maps are made and uncover why the current flood hazard maps may be misleading.

Is there enough dirt in the Mississippi River to save the delta?

I know what you’re thinking: dirt flowing down a river doesn’t sound too exciting. But what if I told you this dirt could be the difference between building and losing physical land on our coastlines? Information like how much sediment is flowing down the river, what kind it is, and where it might end up is important in deciding how people will manage coastlines in a delta. For some places, like the Mississippi River Delta, sediment can be the difference between saving and losing precious natural resources, and even people’s homes.

Throwback Thursday: How did streams and rivers flow before humans started changing things?

Throwbacks aren’t just for old songs and embarrassing childhood photos. Knowing how rivers and streams flowed before people started changing things can help us to create water management practices that are better for the ecological health of these systems. However, the first challenge of throwing it back to these natural flows is just figuring out what these natural flows are.

River Streams Benefit from Fallen Trees

Rivers have suffered the most from human urbanization. Damming, river straightening and removal of large woody debris have disrupted many natural processes essential for healthy habitats of fish, insects and algae. Many land managers have returned fallen trees back into rivers in hopes to improve habitat quality. It wasn’t until this research by Thompson and colleagues that there was clear evidence that this management strategy was successful.

Snow: More Than Just the Backdrop for your Favorite Winter Olympic Sport

Even if you don’t live anywhere near mountains, it is very possible that the water that comes out of your tap originated as snow in the mountains. Many places rely on melting snow from the mountains to supply water downstream for cities, agriculture, and ecosystems. However, melting is not the only thing that can happen to mountain snowpack and scientists are trying to figure out where else it goes and how that could change in the future.
