Last week, I joined my colleagues at COP28 in Dubai , as negotiators and civil society push for a fossil fuel phaseout to meet climate goals. The industry is pushing a narrative that misleadingly calls out emissions , not fossil fuels as the problem. Global net anthropogenic greenhouse gas emissions 1990–2019.

Fossil fuel power plant owners are facing increased accountability for their air and water pollution, including from a new round of environmental and public health protections that are being rolled out by the US Environmental Protection Agency (EPA). We’ve heard these lazily disingenuous narratives before.

And fossil fuel power plants may not stick to their retirement schedules for a variety of reasons. In 2021 alone, the plants slated for retirement emitted more than 28,000 tonnes of nitrogen oxides (NO x ), 32,000 tonnes of sulfur dioxide (SO 2 ), and 51 million tonnes of carbon dioxide (CO 2 ), according to EIA data.

but it inevitably brings forth a mish-mash of half-remembered, inappropriate or out-of-date comparisons between the impacts of carbon dioxide and methane. There is also a very small impact of the CH 4 oxidation to CO 2 itself for any fossil-fuel derived methane. (a) Stocks and flows. References. Etminan, G. Myhre, E.J.

The fossil fuel industry has systematically contaminated our environment with a wide range of toxic chemicals for over a century. One good example of the nexus between global warming and local pollution is ground-level ozone. A study has shown that PM2.5 Another study found high levels of PM2.5

For some parts of the spectrum, the IR can be either absorbed by CO 2 or by water vapour or by clouds, but taking those overlaps into account we find that 50% of the greenhouse effect is from water vapour, 25% from clouds, and about 20% from CO 2 and the rest absorbed by ozone, aerosols, and other trace gases ( Schmidt et al, 2010 ).

volume mixing ratio), together with a number of trace gases, such as argon (0.93% volume mixing ratio), helium, radiatively active greenhouse gases such as carbon dioxide (0.035% volume mixing ratio), and ozone. Fluorinated gases are sometimes used as substitutes for stratospheric ozone-depleting substances (e.g.,
