In the face of a climate crisis, the role of state and local governments in the United States is more crucial than ever. While the federal government may be lacking in climate leadership, states like New York and Maryland are poised to make significant strides in controlling methane emissions, a potent greenhouse gas with a short lifespan. Methane, which accounts for an estimated 30% of human-caused warming over the past century, is removed from the atmosphere much faster than carbon dioxide, making it a critical target for mitigating climate change.
One of the most concerning aspects of methane is its potential to induce an irreversible collapse of the great ocean conveyor, a critical climate tipping point that could be just a couple of decades away. This highlights the urgency of reducing methane emissions, which are currently driven by oil and natural gas systems, agriculture, and landfills. By stopping the release of methane, we can help mitigate climate change over the next few decades, buying us time as we transition away from fossil fuels.
However, there are concerns that state and local governments may not be doing enough to address this issue. In New York, Governor Kathy Hochul's proposal to discount the global warming potential of methane would weaken the state's efforts to mitigate climate change. This proposal has been met with backlash from climate scientists, who argue that it would undercount the short-term impacts of methane pollution. In Montgomery County, County Executive Marc Elrich is urging the county council to export the county's trash to an out-of-state landfill, which would increase methane emissions from landfills.
The decentralized nature of the U.S. political system, with its system of checks and balances, means that state and local governments have a critical role to play in protecting human health and the environment. In fact, it's quite common for state or local entities to adopt environmental regulations ahead of the national government. California's leadership in promoting renewable energy is well-known, and even Republican-dominated states like Texas and Iowa have embraced renewable energy.
As we approach the nation's 250th birthday, it's important to remember that the founders imagined a system in which the states and national government would restrain and complement one another. In the words of James Madison, 'ambition must be made to counteract ambition.' While the Trump administration has failed to lead on climate change, state and local politicians have a critical opportunity to step up and be leaders, not laggards. And a critical weapon in their climate action toolkits is reducing methane pollution.
