Starting at the Bottom: The Potential Impact of Climate Action by Sub-National Entities in the United States

International agreements on climate change action, like the Paris Agreement of 2016, are typically reached by individual countries working together. However, sub-national governments and non-governmental entities pursuing their own policies of combating climate change can often lead to significant positive impact. The United States, which signed and then withdrew from the Paris Agreement, is a model of this scenario.

Blue Carbon and Green Kelp: Kelp forests could reduce carbon emissions

Blue carbon is the carbon that is stored within marine ecosystems. It is being used more frequently within global carbon budgets, which are calculated to help us reduce climate change. Historically, only tidal marshes, mangrove forests, and seagrass beds have been used in calculating stored carbon for carbon budgets. A team of researchers from Norway wanted to see if kelp forests could significantly contribute to carbon storage. They studied the kelp forests along Australia’s southern coast and found their storage potential to be similar to that of the other historically used ecosystems. Conserving and restoring kelp forests could therefore increase carbon storage and help reduce climate change.

Does wearing a face mask make humans less scary to tree sparrows?

Environmental conditions can change quite quickly. In this case, due to the global pandemic of COVID-19 we’ve all been wearing masks when we venture outside. How might this sudden change in our appearance affect animals that frequently live amongst us? Find out how Eurasian tree sparrows responded to wearing masks in two provinces of Sichuan, China.

Some Soil Microbes Don’t Mind Our Camping Trips

Have you ever thought about the microorganisms living under your tent while you’re camping? It may seem like setting up the tent and trampling all over the campsite may harm the organisms that live in the soil but new study in the Arizona savanna turns that idea on its head. Read on to learn about camping resistant plants, microbes, and resiliency of this awesome ecosystem.

From Food Waste to Roadways: Using Compost to Improve Soil Conditions and Tree Success Along Highways

Planting trees along highway roadsides is a good way to increase tree coverage in cities, but getting trees to grow here and maintaining these plantings over time can be difficult. Reducing soil compaction and adding organic material, such as compost, can improve roadside soils and support tree growth in these areas. A 5-year study in Ontario recently found that loosening up the soil and mixing in 10-25% food waste compost relative to soil can help improve tree growth along roadsides, possibly reducing the need to follow up and maintain these trees over time.

In otter news: Disappearing otters and climate change spell double trouble for reefs

As many people know, sea otters are great at being adorable. But do sea otters also play an important role in combating the impacts of climate change? In this study, scientists looked at how the loss of sea otters might be making reefs more susceptible to climate change.

When Fire and Water Collide: Looking to Lakes to Understand Fire’s Deep Past

As I woke up this morning, I learned that a wildfire raging in our local forest had grown to nearly 70,000 acres. A mixture of emotions subsequently flooded in, combining thoughts of concern with questions about how climate change is altering wildfire patterns. In order for scientists and land managers to better predict wildfire outbreaks and to understand the role that climate plays in their behavior, they must first examine the fire history of an area over a long period of time—longer than recorded history. Charcoal and pollen deposits in lake sediments may be able to provide answers to the mysteries of fire’s deep past. Read on to hear about this interesting approach and how one study of lake sediments mapped out 1.5 million years of fire history in China.

Leaving aquaculture ponds ‘out-to-dry’ has implications for nitrous oxide budgets

Researchers from China and the UK have demonstrated that the dormant period of shrimp farming, when aquaculture ponds are drained and left ‘out-to-dry’ for half a year, is associated with increased nitrous oxide emissions. The global aquaculture industry is currently growing at a rate that surpasses most other food sectors, yet the potential climatic impacts from increased greenhouse gas production has implications for the sustainability of this farming system. Through an extended field campaign of nitrous oxide measurements, emissions from the dry-period of aquaculture ponds made up the vast majority of total nitrous oxide emissions. As a previously unaccounted for part of the pond farm greenhouse gas budget, this dry phase of the aquaculture period is too large to be ignored.

Identifying the Urban Populations in Africa at Risk for Malaria from a New Vector

Malaria continues to ravage many parts of the world, particularly in rural sub-Saharan Africa. A recently detected outbreak of malaria in urban areas has now been traced to an invasive species of mosquito from Asia. This species, A. stephensi, thrives in urban settings and its presence in Africa considerably increases the populations that are now at risk of contracting malaria.
