methane and climate

I’ve spent a lot of time over the last decade plus thinking, writing, angsting, and trying to work on climate change issues. This was especially evident during the protracted battle to ban high-volume hydraulic fracturing in New York State, as we also endeavored to help our Pennsylvania neighbors cope with the damage they were seeing from the industry. I was part of a team that wrote comments on media articles and rebutted industry talking points with facts and science.

Because of this, I read a lot of science and heard a lot of speakers on the topics of fracking, fossil fuels generally, and climate change. Because the Binghamton area where I live was one of the most heavily targeted by the fracking industry, there were frequent rallies that drew experts from the Ithaca area, most of whom were connected to either Ithaca College or Cornell University, which is where my daughter T did her undergraduate degree in environmental science.

One of the many environmental warnings that we sounded was the risk of accelerating climate change, particularly due to methane leakage, which occurs at every point from production through transport, storage, and use.

The powers that be didn’t listen.

Atmospheric methane levels climbed to all-time highs, which has the effect of forcing climate change effects in the near-term. While methane is much more short-lived in the atmosphere than carbon dioxide, it is much more potent in trapping heat than CO2, over a hundred times more in a ten-year timespan.

Finally, at the COP26 climate change summit currently meeting in Glasgow, over a hundred countries have agreed to limit methane emissions. In the United States, the Biden administration is finally putting in place regulation of existing fossil fuel wells regarding methane leakage as well as tightening of other rules regarding methane emissions from the fossil fuel industry. Previous efforts targeted new wells only.

One of the sorrows of dealing with climate change is the “what if” factor. What if governments and industry had acted to curtail methane emissions over a decade ago when scientists and activists were pointing out the dangers? What if government and industry had taken global warming from carbon dioxide seriously over fifty years ago when scientists, including industry scientists, made clear the dangers of burning fossil fuels?

If they had, we would not be dealing now with the large increases of extreme weather events, heat waves, floods, and droughts; rising sea levels; loss of glaciers and polar ice; ocean acidification and massive death of corals; weakening of ocean currents; climate refugees; and the threat of even worse consequences in the decades to come.

We can’t redeem the missed opportunities, but we can take action now, including helping those already suffering from climate change impacts.

We can’t afford further inaction.
