What does our trash have to do with the changing climate of the Finger Lakes? More than we might think.
The New York State Climate Impacts Assessment projects that average annual temperatures in the Central/Finger Lakes region will rise 4.6°F to 6.4°F by the 2050s, compared with the 1981-2010 average. By the 2080s, the projected increase is 5.9°F to 10.5°F. The region is also expected to receive more precipitation overall, with more of it falling in heavy bursts.
Trash is part of this climate story. When food and other organic materials break down in a landfill, they produce methane, a powerful greenhouse gas. The Sierra Club reports that landfill gas systems may capture only part of that methane, while decomposing organic waste can continue producing it for decades.
That means reducing food waste, composting when possible, reusing materials and supporting effective waste-diversion programs are some of the most effective local climate actions we can take. Keeping organic material out of landfills can reduce methane production while creating compost that can support healthier soil.
Our climate and our waste system are connected. What we throw away does not simply disappear.
