NASA-funded research using satellites to study atmospheric nitrogen will examine how different farming approaches affect greenhouse gas emissions.

The $1.1 million grant will fund a team of scientists, including two at institutions in Maryland, who will use remote sensing satellites to look for accumulations of airborne ammonia and nitrogen in rural settings.

The researchers will then conduct soil sampling to determine which types of farming methods are better or worse for the climate.

Stephanie Yarwood, PhD - associate professor of environmental science and technology at the University of Maryland - is one of the principal investigators and said this research will help improve climate modeling.

"What we're really trying to do is make a connection between what a satellite can see, which is ammonia, and to make more of a link or less of a link depending on what we find, to nitrous oxide production," said Yarwood. "Because that's really what global models are trying to account for. They're trying to really understand, well how much greenhouse gas emission is there?"

She said as a greenhouse gas nitrous oxide is 300 times more powerful than CO2.

The grant runs for four years with research set to begin this winter.

While air quality measurements in cities are common, there is less data on rural areas. Yarwood said remote sensing satellite technology that can examine atmospheric chemistry at a continental scale is relatively new.

In studying soil contents, researchers hope to establish how microbial communities impact the release of nitrogen into the air and water.

Yarwood said the team will build mathematical models that can predict how nitrogen moves through the soil.

Researchers hope the work will offer hard data on the impact of various conservation practices and help policymakers and stakeholders decide how to spend both time and money.

"A lot of times, there's money invested, either from the government or from the producer," said Yarwood. "There's time in figuring new technologies out and applying those, there's some risk involved in that. I think we really need good data to be able to tell farmers, 'Yes, this is really something that's going to help', and we're going to see less nitrous oxide or not based on that."

The study includes a researcher from the University of California, Irvine - and one at the U.S. Department of Agriculture's Sustainable Agricultural Systems Laboratory in Beltsville.

New polling shows most Americans still favor non-fossil fuel energy sources, but support for certain renewables is not quite as strong these days and a Wisconsin expert hopes the direct impacts of climate change bolster messaging.

The Pew Research Center is out with a new public opinion report on energy choices. Among those surveyed, 63% support the U.S. taking steps to become carbon-neutral by 2050. But support for expanding wind and solar development has gone down from well past 80% to around 75%.

Dr. Ciaran Gallagher, energy and air manager for the climate nonprofit Clean Wisconsin, feels it is important to remind residents climate change is happening at their doorstep.

"We can point to the drought that affected our farmers last summer and then in stark comparison, the intense rain and flooding events we've been experiencing this spring and summer," Gallagher explained.

She mentioned last summer's smoky air from Canadian wildfires as another example. Advocates said such events might help convince the public to regain confidence in renewables as policymakers try to limit climate disasters. Local opposition has surfaced for various solar and wind projects. Gallagher acknowledged it is not surprising, adding misinformation and polarization are driving changing attitudes.

Grid operators warn as more coal plants and other fossil sources come offline to meet clean energy goals, reliability issues might surface in the short term as energy demand soars. But Gallagher countered it does not mean wind and solar are failing to keep the lights on.

"These last few winters, the energy source that has failed is gas power plants," Gallagher pointed out. "Solar and wind in some of the recent storms have outperformed more than they (were) expected (to)."

The Federal Energy Regulatory Commission points out in a 2022 winter storm affecting parts of the Midwest, 90% of prolonged outages were linked to fossil sources.

The Pew survey also showed Americans are not quite as eager to purchase an electric vehicle compared with a few years ago. Gallagher echoed predictions from agencies such as the Bureau of Labor Statistics which indicate organic growth will still happen. She added people taking advantage of federal incentives right now to bring EVs within reach are likely to spur word-of-mouth.

"We're going to see these numbers continue to grow as more people talk to their friends and families that have been early adopters of these technologies," Gallagher predicted.

A new poll shows Idahoans support the development of more clean energy in the state.

In February, 500 likely Idaho voters were surveyed.

Jillian Hanson, climate and renewable energy program manager for The Nature Conservancy in Idaho, said clean energy was a winning issue in this poll.

"Sixty-four percent of Idahoans agree we can both increase the production of clean energy while preserving natural areas, wildlife habitat and the character of our communities," Hanson reported.

Hanson noted 64% of participants in the survey agreed clean energy is economically beneficial for communities, bringing lower energy prices and jobs. The poll was conducted by GS Strategy Group on behalf of The Nature Conservancy in Idaho.

Hanson emphasized proper planning is integral to clean energy production. Last year, The Nature Conservancy released its Power of Place report. It lays out how renewable energy can be developed while still preserving natural and working lands.

Hanson stressed the report shows it is possible and one important element is getting local residents involved.

"In all of this planning conversation, too, robust community engagement is very important from the outset," Hanson asserted. "Engagement that prioritizes community benefits and responds to community concerns."

Hanson noted clean energy can have economic benefits and low impacts on nature at the same time.

"Clean energy technology can provide reliable energy to communities at a marginal cost increase," Hanson added. "It can also create economic opportunities, like in the form of jobs, U.S. manufacturing and more."

Tomorrow Minnesota will reopen online applications for electric bike rebates.

Environmental advocates are closely watching consumer demand for these products, in hopes they'll play a role in emissions reductions.

The state Commerce Department is launching the application period, after a technical issue forced it to shut down the portal last month soon after going live.

The rebates of up to $1,500 are expected to go quickly, and that's welcome news to Lena Reynolds - communications and policy advocate for the Environmental Law and Policy Center.

She said having more e-bikes replace gas-powered vehicles for shorter trips bodes well for improving air quality.

"In places that have done e-bike rebate programs like this before," said Reynolds, "I know Denver, their average participant replaced 22 miles of car trips a week. So, that's a lot of gas that they're not burning."

Research is still coming together on just how much of a dent e-bikes would make in reducing transportation emissions.

But the Policy Center says even when factoring in the manufacturing and charging requirements, an e-bike's climate impact is 93% lower per mile than a fossil-fueled car.

While rebate programs are emerging, the purchase price is still seen as a barrier.

Other policy experts think more coordination is needed in crafting regulations to keep riders and those around them safe.

Reynolds agreed that steps like adding off-street trails could bring a level of balance toward this growth.

As for skeptics who say charging an e-bike still creates a carbon footprint, she said it isn't as bad as they might think.

"And in Minnesota, it's even better," said Reynolds. "Renewables generate the largest share of Minnesota's electricity. So, you know, riding an e-bike is even more sustainable in Minnesota than it would be in other states where fossil fuels are a larger portion of the electricity mix."

When looking at the rebates, Minnesota's discount is 50% to 75% of a buyer's qualifying expenses, depending on their income.

The state of Michigan just adopted a similar program. And just like Denver, Reynolds noted that some cities are offering their own rebates - including Columbus, Ohio.
