Ammonia pollution harms human health and reduces the richness and diversity of the environment. As new policy frameworks are implemented in the UK, there is an opportunity to support farmers to make the changes necessary to reduce ammonia pollution.
The EPA's interest in including a systematic retrospective review element in new regulation has the potential to provide a transparent and well-structured method for assessing which decisions worked well and which didn't. If successful, it could serve as a role model for other regulatory agencies.
President Trump's actions have not yet resulted in demonstrable change in environmental conditions or funding. But the groundwork is being laid to unwind major regulations and diminish staff at the EPA and other federal agencies with climate-related research in their portfolios.
The framework for the Paris negotiations is in sync with what science tells us about how to make effective public policy decisions. This alone makes them historic and may provide a model for both local and global action on more than climate alone.
Negotiators in Paris achieved a historic breakthrough by adopting a fundamentally different, and likely more effective, institutional framework to address climate change. It builds on two concepts missing from past attempts to forge a global treaty: voluntary participation and adaptive policymaking.
The Paris climate conference cannot provide the engine that will drive a solution to the world's climate change challenge. Rather, it can best serve as a mediator that will help guide and structure the swirling, bottom-up process of radical change that is the best hope of preserving Earth's climate.
Because climate change is largely irreversible, mitigation alone won't solve the problem. While mitigation will prevent even greater, future climatic changes, adaptation — efforts to adjust to climate change's effects — will prepare the world for a new set of living conditions, whatever they may be.
As China strives to sustain its upward economic trajectory, it must also address its domestic problems—such as its air pollution and the challenges presented by its aging population—if its people are to share fully in the rewards of economic development and expansion.
Policymakers know that the risks associated with climate change mean they need to cut greenhouse-gas emissions. But uncertainty surrounding the likelihood of different scenarios makes choosing specific policies difficult.
Opponents of action to mitigate climate change often suggest that regulation could have a negative impact on jobs, but stakeholders need to consider benefits, too. For instance, lower emissions could produce savings in the form of lower health care costs, reductions in premature death, and greater well-being.
China's economic transformation over the last three decades has produced potentially deadly air pollution its people inhale every day. But an investment of $215 billion annually could substantially reduce pollution, lessen its drag on productivity, spare the lungs of countless people, and save lives.
Stopping climate change will require the United States and the rest of the world to virtually eliminate emissions over the course of the 21st century. Getting anywhere close to zero emissions demands sustained political and public support, driven by an energy production sector given enough incentives to make carbon reduction succeed.
Mobility — the ability to travel from one location to another — may look very different in the United States in the year 2030. Three key drivers differentiate possible scenarios: the price of oil, the development of environmental regulations, and the amount of highway revenues and expenditures.
Further study, including primary data collection in regions where extraction is occurring, will be important to track the magnitude of emissions and to insure that the DEP's permit requirements are adequate to protect human health and the environment, writes Aimee Curtright.
Carbon dioxide has garnered the most attention in the climate change debate because it accounts for the bulk of greenhouse gas emissions. But there is good reason to worry about methane, say Nicholas Burger and Noreen Clancy.
