Climate-smart agriculture Inflation Reduction Act Activation Guide
A broad range of companies within the food sector can use IRA-funded agricultural programs to support their climate goals. On average, two-thirds of food sector companies’ emissions are generated by farm-level production, making on-farm sustainability critical for abatement.
Liana cutting in selectively logged forests increases both carbon sequestration and timber yields
Infestations of trees by woody climbing plants (i.e., lianas) are common and increasing in an estimated 250 Mha of the 1 billion hectares of mixed-species tropical and temperate forest subjected to selective logging. Cutting lianas that impede the growth of future crop trees (FCTs) in these forests would sequester carbon at low cost and increase timber yields. We estimate that application of this treatment to five liana-infested FCTs per hectare across the 250 Mha of selectively logged forest would result in 0.8 PgCO2 of additional carbon removals by the liberated trees over 30 years at a direct cost of well less than $1.00 MgCO2−1.
Liana liberation: New study shows freeing trees from woody vines is a profitable natural climate solution
Liberating trees from their burdens of woody vines (lianas) is an extremely cost-effective way to improve the economic value of managed forests and help mitigate climate change, according to new research published in Forest Ecology and Management by scientists from the University of Florida, The Nature Conservancy, Conservation International, and partner institutions…
Yale Climate Opinion Maps 2021
This version of the Yale Climate Opinion Maps is based on data through fall 2021. Public opinion about global warming is an important influence on decision making about policies to reduce global warming or prepare for the impacts, but American opinions vary widely depending on where people live. So why would we rely on just one national number to understand public responses to climate change at the state and local levels? Public opinion polling is generally done at the national level, because local level polling is very costly and time intensive. Our team of scientists, however, has developed a geographic and statistical model to downscale national public opinion results to the state, congressional district, and county levels. We can now estimate public opinion across the country and a rich picture of the diversity of Americans’ beliefs, attitudes, and policy support is revealed.
Maps: Tracking air quality and smoke from Canada wildfires
Smoke and haze lingers over sections of North America, as polluted air continues to spread from hundreds of wildfires burning throughout Canada.
This is the current status of air quality across the United States and Canada. (Here’s a guide to understanding air quality readings.)
In early June, the level of particulate matter in the air from smoke became so unhealthy that many U.S. cities set records. Some Canadian cities experienced far worse conditions. At points, it was hazardous to breathe everywhere from Minnesota and Indiana to sections of the Mid-Atlantic region and the South, according to AirNow, a U.S government data source.
Climate change, antibiotics may threaten soil
A study by researchers at the Cary Institute of Ecosystem Studies in Millbrook, New York, has shown that when rising temperatures combine with antibiotic residues expelled by livestock, it degrades soil microbe efficiency, soil resilience to future stress, and its ability to trap carbon…
Breaking down the Inflation Reduction Act program by program, incentive by incentive
The Inflation Reduction Act is the biggest investment in clean energy and climate solutions in American history, so it can be hard to keep track of everything in it. This spreadsheet breaks down the funding opportunities in the bill in a way that allows a variety of users to easily find out which IRA programs and tax incentives can benefit them.
In particular, this spreadsheet was developed for use by:
- State and local/municipal governments
- Tribal Nations
- Businesses
- Non-profits
- Institutions of higher education
- Individual consumers
Study: Climate change increases global risk to urban forests
Climate change threatens the health and survival of urban trees and the various benefits they deliver to urban inhabitants. Here, we show that 56% and 65% of species in 164 cities across 78 countries are currently exceeding temperature and precipitation conditions experienced in their geographic range, respectively. We assessed 3,129 tree and shrub species, using three metrics related to climate vulnerability: exposure, safety margin and risk.
Research: Declining urban and community tree cover in the United States
Urban forests provide many benefits to society, including moderating climate, reducing building energy use and atmospheric carbon dioxide (CO2), improving air and water quality, mitigating rainfall runoff and flooding, enhancing human health and social well-being and lowering noise impacts (Nowak and Dwyer, 2007)…
Cities are rethinking what kinds of trees they’re planting
The U.S. Forest Service estimates that cities are losing some 36 million trees every year, wiped out by development, disease and, increasingly, climate stressors like drought. In a recent study published in Nature, researchers found that more than half of urban trees in 164 cities around the world were already experiencing temperature and precipitation conditions that were beyond their limits for survival.
“So many of the trees that we’ve relied upon heavily are falling out of favor now as the climate changes…”
